Detailed Description

In the prior art, the corresponding double eyelid surgical instruments have many defects, such as incapability of realizing individual customization, incapability of controlling scar formation depth and thickness by adopting bidirectional cautery, and inconvenience in clinical use.

In 1978, the united states dentist Ellman first applied radio frequency waves to dental soft tissue surgery, and then used radio frequency surgical technique as a major breakthrough in the field of electrosurgery, and has been widely used in different medical fields.

The invention provides a new scheme, designs a new double-eyelid operation instrument by utilizing a radio frequency surgical technology, and achieves a minimally invasive traceless double-eyelid operation medical instrument (device) and technology based on radio frequency thermosetting so as to better realize double-eyelid operation and solve the defects existing in the prior art.

The present invention will be described in detail with reference to the accompanying drawings for more clear illustration.

The embodiment of the invention provides a double eyelid operation instrument, which comprises:

The first left puncture complex 100, as shown in fig. 1, the first left puncture complex 100 includes a first left handle body 110 and a first left needle body 120, and the first left needle body 120 is connected to the lower end of the first left handle body 110;

The second left puncture complex 200, as shown in fig. 2, the second left puncture complex 200 includes a second left handle body 210 and a second left needle body 220, and the second left needle body 220 is connected to the lower end of the second left handle body 210;

A first right piercing complex (not shown, reference may be made to the corresponding contents of the first left piercing complex 100), the first right piercing complex comprising a first right handle and a first right needle, the first right needle being connected to the lower end of the first right handle;

A second right piercing complex (not shown, reference may be made to the corresponding contents of the second left piercing complex 200), the second right piercing complex comprising a second right handle and a second right needle, the second right needle being connected to the lower end of the second right handle;

A radio frequency electrocoagulation generator (not shown) for providing radio frequency current to the first left piercing complex 100 and the second left piercing complex 200 and for providing radio frequency current to the first right piercing complex and the second right piercing complex. The rf electrocoagulation generator is for generating high frequency radio waves to perform a surgical operation using the high frequency radio waves between the first left needle 120 and the second left needle 220 (similar between the first right needle and the second right needle). In this embodiment, the rf electrocoagulation generator may provide rf currents for the first left puncture complex 100, the second left puncture complex 200, the first right puncture complex and the second right puncture complex simultaneously, or may provide currents in a time-sharing manner, for example, provide rf currents for the first left puncture complex 100 and the second left puncture complex 200 first and then provide rf currents for the first right puncture complex and the second right puncture complex.

In the double eyelid operation instrument provided by the embodiment, the radio frequency electric coagulation generator utilizes the principle of an electric surgical generator, and the frequency of energy generated by the electric surgical generator is in the frequency range of frequency modulation and amplitude modulation radio wave, so that the radio frequency electric coagulation generator belongs to electric surgery and can be regarded as radio frequency surgery. Thus, the first left needle 120 and the second left needle 220 (the first right needle and the second right needle) of the present embodiment are a type of rf surgical rf knife.

Rf blades in rf surgery are similar in structure to, but differ from, rf blades in at least two ways:

1. the radio frequency electrocoagulation generator of the embodiment outputs high-frequency radio waves with the frequency of 3.0-4.0 MHz, and the high-frequency electrotome outputs high-frequency current with the frequency of 0.1-2.9 MHz;

2. the temperature of the operation electrode can not be increased when the radio frequency knife works, and the cutting, hemostasis and ablation at low temperature can be realized.

When the radio frequency knife electrode guides high frequency radio wave to pass through human body, ions in human tissue vibrate to generate low temperature heat energy, and different surgical effects can be achieved by adjusting the waveform of the radio wave.

The first and second left needles 120 and 220 (first and second right needles) make water molecules in the cells oscillate to generate heat and vaporize to decompose the cells to pressureless fine cut if the radio waves of full filter waveforms are used; the first left needle 120 and the second left needle 220 (the first right needle and the second right needle) can denature collagen of the vascular wall of the tissue and shrink the broken end of the blood vessel to achieve the hemostatic effect if full-wave rectification waveforms are adopted; the first left needle 120 and the second left needle 220 (first right needle and second right needle) can cut and stop bleeding tissue simultaneously if a partially rectified waveform is used.

Compared with the high-frequency electric knife, the first left needle 120 and the second left needle 220 (the first right needle and the second right needle) generate less heat per se, so that the heat damage to the two sides of the acting tissue is low, the range is only 0.01-0.02 mm, the tissue pulling phenomenon caused by the common high-frequency electric knife can not occur, and the first left needle 120 and the second left needle 220 (the first right needle and the second right needle) have obvious boundary between the normal tissue and the tissue due to light carbonization caused by the tissue, so that the tissue healing is fast and the scar is small. Thus, the present embodiment makes use of it to perform a double eyelid operation.

In this embodiment, the RF electrocoagulation generator, although not shown, may specifically be a bipolar electrocoagulation device (power at 0-100W) of model GD 350-S3. Bipolar radio frequency uses biological tissue itself as a heat source, and utilizes its abundant aqueous component to generate heat, which is an internal heating method, also called medium heating. Particularly, polar molecules such as positive and negative electrodes of water molecules in organisms are rubbed with each other along with the high-speed change of the polarities of the capacitance fields under the action of radio frequency alternating capacitance fields, and heat is generated between the two electrodes by high-speed oscillation, so that the local heat effect is good, and the temperature can reach 60-100 ℃. The tissue to be treated can be coagulated, dried and stuck by vascular occlusion, and the carbonization phenomenon, smog and peculiar smell are avoided, so that the tissue is self-heated to realize the purpose of operation. Its advantages include no electric arc between needle and eyelid, no smoke, no odour and no bleeding. Simultaneously, the coagulation and the coagulation are very effective, the electric coagulation speed is high, the maximum coagulation penetration depth can reach 8mm, and the coagulation depth can be adjusted (controlled by the radio frequency output power and the time of acting on tissues). Because no carbonization phenomenon exists, necrosis can be reduced to the minimum extent, and the rapid healing after operation is facilitated.

In other embodiments, the RF electrocoagulation generator may also employ other brands of RF electrocoagulation generators.

The first left handle body 110 is used for being held by an operator in the operation process, and the first left needle body 120 is used for being punctured into a corresponding part of left eyelid by using a needle body part thereof so as to realize double eyelid operation.

The second left handle body 210 is used for being held by an operator during an operation, and the second left needle body 220 is used for being punctured into a corresponding position of left eyelid by using a needle body part thereof so as to realize double eyelid operation.

The first right handle body is used for being held by an operator in the operation process, and the first right needle body is used for being punctured to the corresponding position of the right eyelid by the needle body part of the first right handle body so as to realize double eyelid operation.

The second right handle body is used for being held by an operator in the operation process, and the second right needle body is used for being punctured to the corresponding position of the right eyelid by the needle body part of the second right handle body so as to realize double eyelid operation.

In the present embodiment, as shown in fig. 1, the angle between the first left needle 120 and the first left handle 110 is approximately right angle. It should be appreciated that the first left needle 120 is not a regular straight segment structure (see later in the specification) and therefore, the respective included angles are not straight at least on the respective sides. Likewise, the angle between the first right needle (not shown) and the first right handle (not shown) is approximately a right angle, and at least one side of the corresponding angle is not a straight side. The included angle between the corresponding handle body and the corresponding needle body is basically right angle, which is beneficial to the operation process, and the corresponding puncture complex is more convenient and handy to use. In addition, since the corresponding double eyelid operation is performed, it is also conceivable that the corresponding handle body and the needle body have a corresponding angle therebetween, and that the angle is preferably right or close to right.

In the present embodiment, as shown in fig. 2, the angle between the second left needle 220 and the second left handle 210 is close to a right angle. Likewise, the second left needle 220 is not a regular straight segment structure (see later in the specification), and therefore, the respective included angles are not straight edges on at least the respective sides. Likewise, the angle between the second right needle (not shown) and the second right handle (not shown) is approximately a right angle, and at least one side of the corresponding angle is not a straight side. The included angle between the corresponding handle body and the corresponding needle body is basically right angle, which is also beneficial to the operation process, and the corresponding puncture complex is more convenient and handy to use.

As shown in fig. 1, in the present embodiment, the first left needle 120 is connected to the lower end of the first left handle 110, specifically, below the first left handle 110, but the lower protrusion 111 of the first left handle 110 is inserted into the hole groove 121 of the connecting end of the first left needle 120.

In this embodiment, the first right needle is connected below the first right handle. The lower protrusion (not shown) of the first right grip body is inserted into the groove (not shown) of the connection end of the first right needle body.

The lower protrusion 111 of the first left handle body 110 and the lower protrusion of the first right handle body may have the same structure or may have different structures. Correspondingly, the hole groove 121 at the connecting end of the first left needle 120 and the groove at the connecting end of the first right needle may have the same structure or different structures.

In the present embodiment, as shown in fig. 2, the second left needle 220 is connected to the lower end of the second left handle 210, specifically, the lower end of the side surface.

In this embodiment, the second right needle body is connected to the lower end of the second right handle body, specifically, the lower end of the side surface. Reference may be made to the second left needle 220 and the second left handle 210 for their respective content.

Referring to fig. 3, in the present embodiment, the first left puncture complex 100 and the second left puncture complex 200 are matched together to form a shape as shown in fig. 3.

Referring to fig. 4, a top view of the first left handle body 110 and the second left handle body 210 in the mated state of fig. 3 is shown. In this embodiment, specifically, the first left handle body 110 has a rectangular (specifically, square) top view. The second left handle body 210 has an arch shape (a trilateral frame shape) in plan view, and an area surrounded by the arch shape can surround a rectangle with a space between the arch shape and the rectangle. In other words, as seen in fig. 4, the second left handle body 210 surrounds the first left handle body 110, and there is a slight interval between the first left handle body 110 and the second left handle body 210. Meanwhile, the top view structure of the first left handle body 110 is a square structure, the top view structure of the second left handle body 210 is a three-sided frame structure, and the two structures together form a structure close to a square structure, and the length and width of the large square structure can be about 2.5mm, which refers to the following description.

Although not shown in the drawings, in this embodiment, the first right handle body has a square shape in plan view, the second right handle body has a door shape in plan view, and the area surrounded by the door shape can surround the square shape with a space therebetween. Reference is made to the corresponding content of fig. 3 and 4.

It should be noted that the rectangle (the first left handle body 110) and the square (the first right handle body) may have the same shape, or may have different shapes (e.g. different lengths and widths). The arch shape (the planar shape of the second left handle body 210) and the gate shape (the planar shape of the second right handle body) may have the same shape or may have different shapes.

Referring to fig. 5, the double eyelid surgical instrument further includes a left handle socket 300 and a left plug 400 electrically connected to the left handle socket 300, the left handle socket 300 for electrically connecting the first left piercing complex 100 and the second left piercing complex 200 with a radio frequency electrocoagulation generator; the right hand socket is used for electrically connecting the first right puncture complex and the second right puncture complex with the radio frequency electrocoagulation generator.

The left handle socket 300 is a socket with electric wires, the socket part forms a corresponding relation with the first left handle body 110 and the second left handle body 210, when in use, the first left handle body 110 and the second left handle body 210 of the left handle socket 300 are connected, and can be combined with reference figures, and the other side of the left handle socket 300 is connected with the radio frequency electrocoagulation generator through a plug.

It should be noted that, the left handle socket 300 and the right handle socket may be the same, i.e. one set of double eyelid surgical instruments may have only one handle socket; of course, the left handle socket 300 and the right handle socket may be separate, two different handle sockets.

Referring to fig. 6, the left handle socket 300 is shown mated with the first left piercing complex 100 and the second left piercing complex 200. The body is the first left handle body 110 and the second left handle body 210 after the mating together, i.e. they occupy the largest height portion, and the overall proportion of the left handle socket 300 is usually at most 1/6 to 1/7 of the total height of the composite body (mainly the needle body height) after the left handle socket 300 is inserted (it should be noted that the drawings are not strictly shown to scale), so that the operator can still perform some hand-holding operations and accurately position the left handle socket 300 after the operator inserts the left handle socket. While 300-left handle socket is energized, typically by foot pedal (not shown) of the corresponding rf electrocoagulation generator.

Referring to fig. 1 and fig. 7 in combination, in the present embodiment, the first left needle 120 and the first left handle 110 are detachable. Specific reference is made to the associated structure of the subsequent protrusions 111 and the aperture slots 121 for a removable structure. Similarly, although the first right needle and the first right handle are not shown in this embodiment, the first right needle and the first right handle are detachable from each other. The structures of the first right needle body and the first right handle body may refer to the contents of the first left needle body 120 and the first left handle body 110.

Referring to fig. 7, the bottom surface of the first left handle body 110 has a downward protrusion 111.

Referring to fig. 7 and 8 in combination, fig. 8 is a schematic bottom view of the first left handle 110. It can be seen that the bottom view of the protrusion 111 is in the shape of a cross.

Referring to fig. 7 and 9 in combination, the connection end of the first left needle 120 has a hole groove 121 that mates with the protrusion 111.

Fig. 9 shows that the shape of the hole groove 121 in plan view is also a cross shape. The cross shape of the hole groove 121 corresponds to the cross shape of the protrusion 111 so that the protrusion 111 can be fitted into the hole groove 121.

As described above, in this embodiment, the protrusion 111 is matched with the hole groove 121 to realize the detachment of the first left handle body 110 and the first left needle body 120.

It should be noted that, in this embodiment, the side surfaces of the protrusion 111 and the side walls of the hole groove 121 may have a textured structure (or a wire drawing structure, not shown), so that when the first left handle body 110 and the first left needle body 120 are matched, they are more firm and not easy to be separated during the operation. When the first left handle body 110 and the first left needle body 120 are separated, separation (disengagement) may be achieved by an auxiliary tool such as forceps.

Although not shown, in this embodiment, the bottom surface of the first right handle body has a downward protrusion, and the connecting end of the first right needle body has a recess that mates with the protrusion. Likewise, the protrusions and recesses are also used to enable the first right handle body and the first right needle body to be detachable. Accordingly, although not shown in the drawings, in the present invention, the bottom-view shape of the protrusions is a cross shape, and the top-view shape of the grooves is also a cross shape.

In this embodiment, the protrusion may be the same as the protrusion 111, or the protrusion may be different from the protrusion 111. Accordingly, the cross shape may be the same as the cross shape, or the cross shape may be different from the cross shape. The shape of the groove corresponds to the protrusion, and thus, the shape of the groove may be the same as the hole groove 121 or may be different from the hole groove 121.

Referring to fig. 7 and 9 in combination, in this embodiment, a pull wire (not shown) is connected to the connection end of the first left needle 120, the connection end of the first left needle 120 has micropores (not labeled as shown in fig. 7 and 9), and the pull wire is tied to the connection end through the micropores (not labeled as shown in the cylindrical structure in fig. 7 and 9, or in other embodiments, the connection end may not be cylindrical).

The pull wire is used to facilitate the subsequent pulling of the first left needle 120 from the eyelid of the subject. This is because, in the present embodiment, the first left needle 120 needs to be inserted into the eyelid of the operator at first, and then in order to prevent the first left handle 110 from affecting the use of the second left puncture complex 200, the first left handle 110 needs to be detached first, and after the second left puncture complex 200 completes the puncture, the first left handle 110 and the first left needle 120 are assembled together, and then the electric heating is performed. At this time, the traction wire can facilitate the removal of the first left needle 120 from the eyelid of the operated person in various cases.

It should be noted that, in other embodiments, there may be no micro-hole, that is, a non-micro-hole manner may be adopted, and the traction wire is tied to the connection end of the first left needle 120.

Although the drawing shows, the first right needle connecting end may be connected with a pulling wire, and the first right needle connecting end may have a fine hole, and the pulling wire is tied to the connecting end through the fine hole. The pull wire may be the same as the pull wire or may be different from the pull wire. Accordingly, the micropores may be the same as or different from the micropores, and reference is made to the foregoing.

Referring to fig. 1 and fig. 7 in combination, in the present embodiment, a side surface of the first left handle body 110 has a first left label hole 112 (as shown in fig. 7), and the first left label hole 112 is used for detachably connecting with the first left label pin 130; the first left label pin 130 has the same shape as the first left pin body 120, and the first left label pin 130 has graduations thereon. The first left label pin 130 may be a paper pin, thereby saving cost.

Although shown, the side surface of the first right handle body is provided with a first right label hole which is used for detachably connecting with the first right label needle; the shape of the first right label needle is the same as that of the first right needle body, and the first right label needle is provided with scales. The first right tag pin may be a paper pin body, thereby saving costs.

Referring to fig. 2 and 11 in combination, the second left handle body 210 has a second left label hole 211 (as in fig. 11) on a side surface thereof, and the second left label hole 211 is used for detachably connecting the second left label pin 230; the second left label pin 230 has the same shape as the second left pin body 220, and the second left label pin 230 has graduations thereon. The second left label pin 230 may be a paper pin, thereby saving cost.

Although shown, the side surface of the second right handle body is provided with a second right label hole which is used for detachably connecting a second right label needle; the shape of the second right label needle is the same as that of the second right needle body, and the second right label needle is provided with scales. The second right tag pin may be a paper pin, thereby saving cost.

The label needle of each part aims at being used as a running indication plate of an actual needle body, and the shape, the width and the length of the label needle are consistent with those of the corresponding needle body, so that the label needle is used as a running indication of the tissue needle inserting direction. After the needle body is inserted, the paper running indication plates, namely the label needle, can be removed.

In this embodiment, although not shown in the drawings, the side surface and a part of the bottom surface of the first left handle body 110 are provided with insulating coatings; the side surface and a part of the bottom surface of the second left handle body 210 are provided with an insulating coating. That is, the first left handle body 110 has only the top surface without an insulating coating, because this portion needs to be electrically connected to a corresponding socket. However, the downward projection 111 of the first left handle body 110 is also not insulated, i.e., there is no insulating coating, because the present embodiment is electrically connected to the corresponding first left needle body 120 through the projection 111. The sidewall surface of the corresponding hole groove 121 of the first left needle 120 may also be insulated to ensure electrical connection between the first left handle body 110 and the first left needle 120.

The side surface and part of the bottom surface of the first right handle body are provided with insulating coatings; the side surface and part of the bottom surface of the second right handle body are provided with insulating coatings. The first right grip downward projection is devoid of an insulating coating and reference is made to the corresponding reasons and content of the first left grip 110 and the second left grip 210 described above.

The curved side surface and the curved lower surface of the first left needle 120 have an insulating coating. The curved side and the curved upper surface of the second left needle 220 have an insulating coating. That is, this embodiment allows the first left needle 120 to have only a portion without the insulating coating surrounding (wrapping) the insulating coating except for the connecting end (the surface of the sidewall of the well 121). These portions without the insulating coating are just the surfaces seen in the drawing, i.e., the upper surfaces of the first left needle 120 except the connecting end, which are the positions for forming the double eyelid.

It should be noted that the curved side surface, the curved upper surface and the curved lower surface are mentioned above because the needle body is generally flat or elongated conical without a flat surface, and thus, by curved, the division is a general division, adding the curved side surface, the curved upper surface and the curved lower surface is a complete outer surface, and wherein the curved upper surface and the curved lower surface each occupy about one quarter of the whole surface.

Similarly, in this embodiment, only a portion of the second left needle 220 does not surround the insulating coating. These portions (not shown) without insulating coating are just the portions of the second left needle 220 except the connecting end (the connecting end of which has been fixed into the second left handle body 210 and the two are electrically connected), and the lower surfaces of the second left needle 220 are not coated with insulating coating, whereas these lower surfaces of the second left needle 220 are just opposite to the corresponding upper surfaces of the above-mentioned first left needle 120, and the eyelid structures (orbicularis oculi) between them are just the portions that need to be heated during the operation to well achieve the corresponding double eyelid operation.

That is, in this embodiment, except for those positions where electrical connection is to be achieved and where it is to be used to form double eyelids, it is desirable that the positions be insulated, and therefore, an insulating coating may be provided.

The curved side surface and the curved lower surface of the first right needle body are provided with insulating coatings. The curved side surface and the curved upper surface of the second right needle body are provided with insulating coatings. The insulation coating of the first right needle and the second right needle may refer to the corresponding contents of the insulation coating structure of the first left needle 120 and the second left needle 220.

The insulating coatings are prepared to realize the directional thermosetting effect on the surface of the corresponding needle body. That is, the heat is not generated at the position where the heat is needed, but only at the position where the heat is needed. Namely, the first left needle 120 and the second left needle 220 form directional thermosetting between the first left needle 120 and the second left needle 220 through the insulating coating structure, so that the normal tissue is prevented from being thermally damaged.

It should be noted that, the insulating coatings are not shown in the figures (one of the reasons is that the insulating coating is usually a thin layer), but it should be understood that they may be made of insulating materials harmless to human body, such as medical silica gel sleeves or nontoxic insulating metal plating materials, or other suitable materials. Their process may be by coating, electroplating (or even welding) or other suitable means to form an insulating coating on the corresponding surface of the corresponding needle.

Referring to fig. 9, in the present embodiment, the top view of the first left needle 120 is the top view of the double eyelid. Although not shown, the second left needle 220 also has a top view of the double eyelid.

Referring to fig. 10, the first left needle 120 has a curved shape in side view, which is the same as the curved shape of the eyelid itself (the curvature of the eyelid is also substantially the same as that of the eyeball). It should be noted that, in fig. 10, the bending direction of the first left needle 120 is shown as being upwardly bent, and generally, in operation, when the first left needle 120 penetrates into the eyelid of the operated person lying on the operation table, the bending direction is downward (it is easy to know that the bending is directly related to the curved surface of the eyeball); however, fig. 10 is not illustrated as not being shown in the right direction, since downward and downward are merely angles of placement, and fig. 10 is placed so as to be more easily referred to and correspond to the other figures.

Although not shown, the second left needle 220 is also curved in side view, and reference is made to fig. 10.

In this embodiment, the first left piercing complex 100 serves as a deep piercing portion of the double eyelid line. The structure actually used for puncturing is the first left needle 120. As can be seen from the foregoing, the first left handle body 110 of the first left puncture complex 100 has a three-sided frame shape as a whole. The first left handle body 110 has a square shape (three-frame shape) with a region cut in a top view, and the square shape may have a length and a width of 2.5mm when viewed alone. And the height of the three-frame body can be 30mm. The material of the first left handle body 110 may be medical stainless steel. The outer surface of the first left handle body 110 may be coated with a thin layer of medical silicone as an insulating coating.

In this embodiment, the second left piercing complex 200 serves as a superficial piercing portion of the double eyelid line. The structure actually used for puncturing is the second left needle 220. As can be seen from the foregoing, the second left handle body 210 of the second left puncture complex 200 has a rectangular parallelepiped shape, and the top surface of the second left handle body has a square shape with a length and a width of 2mm. While the height of the entire cuboid may be 30mm. The material of the second left handle body 210 may be medical stainless steel, and the surface of the second left handle body 210 is coated with a thin layer of medical silica gel as an insulating coating.

In other embodiments, the second left handle body 210 may leave a portion of about 15mm in length attached to the corresponding handle socket without an insulating coating.

The second left handle body 210 is connected to the second left needle body 220 and is not necessarily made to be detachable.

The needle shapes of the first left needle 120 and the second left needle 220 are arc-shaped to simulate the shape of double eyelid, and the needle may be flat (flat shape is better) or tapered cylindrical.

The first left needle 120 and the second left needle 220 may have a width of about 2mm and a length of about 20mm, and may be manufactured in sets of progressive sets, e.g., from 16mm to 26mm, at a level of each 2mm, as 6 sets of different kits. Meanwhile, different complete products can be manufactured through different bending radians, for example, complete products can be gradually formed according to 2 radian levels, so that the requirements of different-length and different-radian individualized double eyelid threads are met.

In this embodiment, the tips of the first left needle 120 and the second left needle 220 are preferably blunt tips to prevent bleeding during penetration of tissue.

In this embodiment, as can be seen from the figures, when the two handles are connected after the two needles are inserted into the corresponding positions of the eyelid, the first left handle 110 and the second left handle 210 are arranged side by side and close to each other, but are insulated from each other. The reason for the insulation comes partly from the insulating coating they have on their surface and partly from the small spacing between them. And their top surfaces are all conductive surfaces so that electrical connection can be made through corresponding handle sockets.

It should be noted that, in other embodiments, even the upper half of the first left handle body 110 and the second left handle body 210 may have a height of about 15mm without wrapping the insulating coating, so as to be better electrically connected with the handle socket. The electrical insulation between the first left handle body 110 and the second left handle body 210 at this time mainly depends on the corresponding minute interval.

The present embodiment mainly uses the instrument structure for the left-eye double-eyelid operation as an example, and thus, fig. 1 to 11 are mainly all instrument parts for the left-eye double-eyelid operation (except that the left handle socket 300 and the left plug 400 in fig. 5 can be directly used as the corresponding right handle socket and the right plug), and according to the instrument structure for the left-eye double-eyelid operation, only the instrument structure for the right-eye double-eyelid operation (including the structures of the aforementioned first right puncture complex, second right puncture complex, etc.) can be obtained by symmetrically manufacturing the instrument structure. Thus, although not shown, one skilled in the art can derive the corresponding structure from the present description.

In connection with the foregoing, the procedure of performing the corresponding double-eyelid operation using the double-eyelid operation instrument of the present embodiment may be as follows (the double-eyelid operation for the left eye is described as an example):

before an operation, designing and drawing lines on the skin surface by double eyelid design;

after the disinfection and towel spreading are finished, local multipoint infiltration anesthesia can be carried out by adopting lidocaine;

Then, according to the designed drawing line, the eyelid skin is punctured by a minimally invasive incision knife from the outer side of the eyelid to form a micro incision with the length of about 3 mm;

Selecting matched double eyelid surgical instruments according to a double eyelid line, firstly obtaining a combined first left puncture complex 100, holding a first left handle body 110 of the first left puncture complex 100 to puncture the needle tip of a first left needle body 120 from a micro incision to reach the surface of the eyelid, wherein the resistance sense can be realized at the moment, then, the double eyelid surgical instruments are turned into a transverse needle insertion mode, and the double eyelid surgical instruments transversely penetrate through the upper eyelid to reach the inner canthus angle double eyelid line design end point along a double eyelid design line; the whole needle part (i.e. the part except the connecting end) of the first left needle 120 is penetrated into the tissue, and the needle running position can be more clearly known by using the first left label needle 130 in the penetrating process; during the puncturing process, the first left needle 120 walks in the gap between the orbicularis oculi muscle and the meibomian;

After the needle body is determined to run according to the design and is positioned accurately through the first left label needle 130, the first left label needle 130 is removed;

Thereafter, the first left handle body 110 is detached (detached) from the first left needle body 120, thereby preventing the first left needle body 120 from affecting the puncturing operation of the subsequent second left needle body 220;

In the same manner as above, the second left handle 210 of the second left puncture complex 200 is held by hand to puncture the tip of the second left needle 220 from the micro incision, and after the second left needle 220 is punctured from the micro incision, the gap between the subcutaneous tissue and orbicularis oculi is followed, and the upper eyelid is penetrated laterally; during the puncturing process, the second left label pin 230 can be utilized to more clearly know the running position of the needle body; after determining positioning readiness, the second left label pin 230 is removed;

Then, the first left handle body 110 is assembled with the first left needle body 120 again, and the state can be combined with reference to fig. 3, the first left needle body 120 and the second left needle body 220 form a double-needle radio-frequency thermosetting loop, and the needle bodies are completely attached to the respective handle body parts;

The left handle socket 300 is reversely buckled on the first left handle body 110 and the second left handle body 210, the state can be combined with reference to fig. 6, the first conductive jack 310 of the left handle socket 300 is sleeved on the first left handle body 110, the second conductive jack 320 of the left handle socket 300 is sleeved on the second left handle body 210 (namely, the cuboid and the conductive part of the bow are respectively inserted into the jacks of the sockets), and the left plug 400 electrically connected with the left handle socket 300 is plugged into the corresponding radio-frequency thermosetting generator;

the RF heat coagulation generator adjusts parameters, the energy can be set to be 10 joules, the heat coagulation time is 20s, and the corresponding operation heating process is carried out;

After heating, the left handle socket 300 can be pulled out and the needles withdrawn in the same way. The first left needle 120 may be removed through the pull wire at the tail.

After the operation is finished, the operator can be instructed to open eyes to check the formation condition of the double eyelid, and at the same time, the micro incision is not needed to be sutured, and the upper eyelid can be coated with the antibiotic eye cream after the operation is finished.

The same method process is applicable to right eye surgery.

During the above-described operation, heat is generated by vibration between the first left needle 120 and the second left needle 220 to form a heat coagulation region. The current heats up between the first left needle 120 and the second left needle 220 with a current density that is large enough to create a linear heat set that is much larger than the monopolar rf heat set range. The radio-frequency thermosetting of the double-needle electrode has obvious directivity and accuracy, no matter how much the distance between the two electrodes is, the thermosetting is carried out between the double-needle electrodes, and the peripheral thermosetting range of the electrodes is very small and does not increase with the increase of the distance. Therefore, the double-needle electrode radio frequency operation has less damage to peripheral tissues and high accuracy and safety.

It can be seen that the operation performed by using the double eyelid operation apparatus of the present embodiment has the following advantages (i.e., the double eyelid operation apparatus has the following advantages):

1. Minimally invasive, no need of cutting skin, basically no bleeding in operation, small wound, small eyelid swelling after operation, quick recovery, and natural double eyelid in the next day; 2. no skin scar formation; 3. the double eyelid line is stable, is not easy to lose in long term, and can permanently maintain the appearance of the double eyelid; 4. the operation is simple and the time is short; 5. the directional low-temperature coagulation is adopted in the operation, so that the damage to surrounding tissues is small, normal tissues are not easily damaged, and the operation risk is small; 6. because the tissues are not removed, the appearance of the double eyelid after operation is natural, the phenomenon of eye closing meat strips is avoided, and the natural effect of eye closing without marks can be realized; 7. the height and the shape of the double eyelid can be individually designed (namely, the shape of the needle body can be customized).

The above examples are only for illustrating the technical scheme of the present invention and are not limiting. It will be understood by those skilled in the art that any modifications and equivalents that do not depart from the spirit and scope of the invention are intended to be within the scope of the appended claims.
