Description
Technical Field
The present invention relates to a tool for catgut implantation, and more particularly, to a thread inserter for inserting a thread into a human body.
Background
A thread-embedding therapy (thread-embedding therapy) for strengthening muscles or improving skin sagging or wrinkles by inserting threads into the dermis or the sarcolemma (SMAS, Superficial muscle aponeurotic System) of human skin or the like has been developed and widely used.
One example of a conventional wire inserter used in such a catgut embedding procedure is illustrated in fig. 1. In the conventional wire inserter as exemplarily shown, a through portion 13 extending inside an insertion needle 10 is open at a sharp distal end, a handle 12 is provided on a rear end portion side RD of the insertion needle 10, a wire 20 and a fixing member 30 are provided on the distal end portion 13 side of the insertion needle 10, the wire 20 is inserted into a part of the through portion 11 in a longitudinal direction, and the fixing member 30 fixes the wire 20, which is drawn out to the outside from the through portion 11 of the insertion needle 10, to the insertion needle 10 in the longitudinal direction. In order to minimize pain occurring during the operation or side effects that may remain after the operation, a thin insertion needle 10 is used in the thread inserter 10, and a thin thread 20 that can be inserted into the through portion 11 of the insertion needle 10 is used.
In the case of a thread burial operation using such a thread inserter, if the insertion needle 10 is inserted into a human body, the thread 20 is drawn into the inside of the human body by means of the insertion needle 10.
When the insertion needle 10 is pulled out from the human body in a state where the string 20 reaches a desired portion in the human body, the string 20 is pulled out from the through-portion 11 of the insertion needle 10 and remains in the human body. Thus, the thread 20 inserted into the human body stimulates and pulls the tissue inside the human body, providing the effect of strengthening the muscle or improving the sagging or wrinkles of the skin. An example of a prior art wire inserter is proposed in korean patent laid-open publication No. 10-0473108.
Disclosure of Invention
In order to greatly obtain the operation effect of strengthening muscles or improving skin sagging or wrinkles through a thread burying operation of inserting a thread into the inside of a human body, it is more advantageous to insert a thread thicker than a fine thread into the inside of a human body. This is because the larger the surface area of the skin in contact with the silk threads remaining in the skin, the more collagen formation is induced, and an effectively improved operation can be performed.
However, in the conventional thread inserter, since an insertion needle having a small diameter is used in order to minimize pain and side effects caused by the thread burying operation, it is difficult to insert a thick thread through a through-hole formed inside such a thin insertion needle. Therefore, in order to improve the surgical effect by using the conventional wire inserter, it is necessary to insert a plurality of strands of fine wires into the same surgical site by a plurality of times of thread embedding surgeries. There are problems in that the operation time becomes long, the operator feels great pain during the operation, and side effects such as bleeding or hematoma may be seriously occurred at the operation site after the operation.
In order to solve such a problem, a thread inserter in which a thread 40 is spirally wound on an insertion needle 10 has been proposed as shown in fig. 2. A part (distal end) of the wire 40 in the longitudinal direction is inserted into the through portion 11 of the insertion needle 10, the remaining part of the wire 40 in the longitudinal direction is spirally wound around the outer periphery of the insertion needle 10, and the rear end (distal end) thereof is fixed by being inserted into the fixing member 30. However, in this type of thread inserter, the pitch interval (PS) at which the thread 40 is wound around the outer circumference of the insertion needle 10 is wide, and the rear end portion of the thread 40 is simply fixed by penetrating the fixing member 30, and thus it is difficult to insert the thread 40 into the human body. Specifically, at the time of a thread burying operation using the thread inserter, if the insertion needle 10 is directly inserted into the human body, the thread 40 cannot maintain a shape wound around the outer circumference of the insertion needle 10 but is pushed to the rear of the insertion needle 10 and loosened. Therefore, the thread 40 cannot be inserted into the human body while maintaining its original shape, and as a result, the thread 40 cannot be sufficiently filled in the surgical site, and it is difficult to obtain a large surgical effect.
On the other hand, in order to insert the thread 40 into the human body while maintaining the spiral shape, the insertion needle 10 is rotated to penetrate the human body in accordance with the direction in which the thread 40 is wound around the outer circumference of the insertion needle 10 and the pitch interval PS. Therefore, there are considerable difficulties in performing catgut embedding surgery using a wire inserter. Even if the thread 40 is inserted into the human body in a spiral shape, it is difficult to expect a filling effect and an elastic effect of the thread 40 for spreading wrinkles or giving elasticity to sagging skin in the human body, for example, subcutaneous tissues or the like under the portion where wrinkles or sagging skin is present, because of the shape in which the pitch interval PS of the thread 40 is wide.
The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a thread inserter which can be inserted into and retained in a human body while maintaining a spirally wound state without pushing a winding portion spirally wound around an outer periphery of an insertion needle to the rear of the insertion needle even when the insertion needle is inserted into the human body in a linear direction. Accordingly, the present invention provides a thread inserter in which a wound portion of a thread is tightly and firmly wound around the outer periphery of an insertion needle, the wound portion is simply embedded in a desired portion without being pushed at all even if the insertion needle is straight and not rotated during an operation, and after the insertion needle is embedded in a human body, if only the thread is pulled, the thread is cut off in the interior, the elastic force of the wound portion is released, and only the insertion needle can be simply pulled out. As another proposal, a thread inserter is provided in which after embedding a thread, a predetermined length of a wound portion wound around the outer periphery of an insertion needle is left in the skin by a simple operation using a structure such as an ejector pin, and only the insertion needle can be easily pulled out. In this case, the present invention may provide a thread inserter in which a knotted portion or a fixing ring is formed as a fixing portion required for preventing a thread wound behind a winding portion of the thread from loosening.
A wire inserter of an exemplary embodiment aiming at solving the above-described problems may be provided with: an insertion needle having a sharp distal end portion and having a penetrating portion extending in a longitudinal direction and opened at the distal end portion; and a thread including a first extension portion inserted into the through portion of the insertion needle, a second extension portion extended from the first extension portion toward the front of the insertion needle, and a grip portion extended so as to be exposed from the first extension portion to the outside of the insertion needle by a predetermined length and capable of being pulled by hand, the thread including a winding portion wound in a spiral shape around the outer periphery of the insertion needle; after the insertion needle around which the yarn is wound is inserted into the human body, the holding portion exposed to the rear of the insertion needle is pulled to cut the yarn passing over the distal end portion of the insertion needle, and the tension of the wound portion of the yarn is released and a gap is formed between the wound portion and the insertion needle, so that the wound portion is left in a state of being buried in the human body, and only the insertion needle can be easily removed.
In addition, the holding portion of the string may be provided with a handle so that the user can easily grasp the string with his hand.
Further, a fixing portion for preventing the thread wound around the outer periphery of the insertion needle from loosening may be formed behind the winding portion of the thread.
In addition, the fixing part may include a knotting part or a fixing ring that is tied to the rear end portion of the winding part so as to prevent loosening.
The fixing portion may be formed of either a connecting portion wound around the outer periphery of the insertion needle in a staggered manner or an adhesive portion fixed by thermally fusing or adhering a thread to an adhesive.
A wire inserter according to another embodiment to solve the problem may include: an insertion needle having a sharp distal end and having a through-hole formed therein so as to penetrate in a longitudinal direction; and a thread including an insertion portion inserted into the distal-end-side through portion of the insertion needle by a predetermined length, and a winding portion extended from the insertion portion and spirally wound around the outer periphery of the insertion needle; and a thimble inserted into the rear through part of the insertion needle in a manner of advancing and retreating, capable of advancing to the front end side of the insertion needle and pushing the insertion part of the silk thread to the front side by a predetermined length; after the insertion needle with the thread wound thereon is inserted into the human body, the thimble is advanced to push out the insertion portion of the thread inserted into the insertion needle to the tip side, so that the wound portion is released in a state of being in close contact with the outer periphery of the insertion needle, and a gap is generated between the wound portion and the insertion needle, whereby the wound portion is left in a state of being buried in the human body, and the insertion needle can be easily removed.
The diameter of the thimble may be smaller than the inner diameter of the insertion needle penetration portion but larger than or equal to the diameter of the thread.
Further, the insertion needle may be configured such that a handle is provided on the outer periphery of the rear end portion of the insertion needle, the thread insertion portion is inserted into the insertion needle front end side through portion up to the front of the handle, and the thimble is inserted into the insertion needle rear side through portion so as to be positioned rearward of the thread insertion portion.
In addition, a fixing portion for preventing the thread wound around the outer circumference of the insertion needle from loosening may be formed behind the winding portion of the thread.
The fixing portion may be formed of either a connecting portion wound around the outer periphery of the insertion needle in a staggered manner or an adhesive portion that is fixed by thermally fusing or adhering the thread to the insertion needle with an adhesive.
In addition, the fixing part may be configured to include a knotting part or a fixing ring that is tied to the rear end portion of the winding part so as to prevent loosening.
If the thread inserter according to one embodiment of the present invention is used, a portion of the thread penetrating the insertion needle penetration portion in the length direction is continued to the outside of the insertion needle penetration portion, a winding portion wound spirally around the outer circumference of the insertion needle is formed, and knotting is performed at the rear end portion of the winding portion so as to be fixable, or another fixing portion such as a fixing ring is provided for fixing, so that the thread is not easily pushed to the rear when the insertion needle is inserted into the human body, and thus the thread can be easily left in the skin. Further, if the winding portion is located at a desired position of the human body, the operation is very convenient because the thread passing over the sharp distal end of the insertion needle is cut off by pulling the holding portion of the thread exposed to the rear of the insertion needle, the tension of the winding portion is released, a predetermined length is released, a predetermined gap is formed between the winding portion and the insertion needle, and the winding portion is left in a state of being buried in the human body, and the insertion needle can be simply removed.
On the other hand, if the winding portion is located at a desired position of the human body, the winding portion following the insertion portion is unwound by a predetermined length from the outer periphery of the insertion needle and a space is formed between the winding portion and the insertion needle, so that the winding portion is left in a state of being buried in the human body, and the insertion needle can be simply removed, thereby providing a very convenient operation.
Thus, the present invention does not require the insertion needle to be inserted into the human body while rotating as in the prior art, and therefore, the use of the wire inserter is convenient, and the pain of the operator can be reduced.

Fig. 5(b) illustrates a method of fixing the yarn at the terminal end of the winding portion of the yarn by using a fixing ring as a fixing portion without forming the knotted portion. If necessary, the knotting portion and the fixing ring may be overlapped with each other, or may be arranged at a predetermined interval from each other.
In fig. 3, arrow FD indicates a direction toward the front end 113 side of the insertion needle 110, and arrow RD indicates a direction toward the rear end side of the insertion needle 110 where the handle 112 is located. The insertion needle 110 of the embodiment may refer to "injection needle" and the like in the corresponding field.
As shown in fig. 3, the thread inserter 100 is composed of an insertion needle 110 and a thread 120, and this thread inserter 100 is provided with a fixing portion 126 that fixes a rear end of the thread wound in a spiral shape on the insertion needle so as not to loosen, and as the fixing portion, a knotting portion 126 that knots and fixes the thread using a linking portion 125 may be used to fix the wound thread so as not to loosen. In the drawings, although both the knotted portion 126 and the fixing ring 130 are illustrated, one may be selectively used.
On the other hand, the insertion needle 110 has an elongated tubular shape with a sharp leading end portion 113 so as to be inserted into a human body. The insertion needle 110 has a penetrating portion 111 extending in the longitudinal direction inside thereof and opened at a distal end portion 113, and a handle portion 112 at a rear end portion thereof to be grasped by fingers of an operator. At this time, since the first extension portion 128 and the second extension portion 127 of the wire 120, which will be described later, are bent 180 degrees over the distal end portion 113 of the insertion needle 110, if one end portion of the wire 120 is pulled rearward RD, the insertion portion 121 of the wire is pressed against the sharp distal end portion 113 of the insertion needle 110 and can be easily cut. Such an insertion needle 110 is generally formed of a metal material, and the handle 112 is formed of a plastic material, but is not limited thereto. That is, the insertion needle 110 may be formed of a plastic material, particularly a transparent plastic material, so that the wire 120 inserted into the through-hole 111 inside thereof can be visually recognized, and the handle 112 may be formed of a metal material, or a composite of a metal material and a plastic material.
The thread 120 is used for insertion into a human body, strengthening muscles or regenerating aged skin, increasing skin elasticity, and improving sagging or wrinkles of the skin, and a surgical suture, particularly, a biodegradable suture (biodegradable suture) that is partially dissolved in the human body may be used as the thread 120.
The thread 120 includes a first extension 128 inserted into the through-hole 111 of the insertion needle 110 and extended to be exposed to the outside of the handle 112 at the rear of the insertion needle 110, and a second extension 127 connected to the tip of the first extension 128, and spirally wound around the L1 on the outer peripheral portion of the insertion needle 110 via the sharp tip 113 of the insertion needle 110.
The first extension 128 of the thread 120 includes an insertion portion 121 inserted into the through portion 111 of the insertion needle 110, and a grip portion 122 exposed and extended to the rear of the insertion needle 110 so that an operator can pull the thread with a hand. In this case, the grip portion 122 may be formed with a handle 122a to be easily grasped by a hand of an operator, and the handle 122a may be formed by forming the grip portion 122 in a ring shape or by forming another member such as plastic to be easily grasped by a hand of an operator.
The second extension 127 of the thread 120 is constituted by a winding portion 123 and a fixing portion 126, the winding portion 123 is densely and strongly wound spirally around the outer periphery of the insertion needle 110 from the sharp front end 113 of the insertion needle 110 to the rear RD, and the fixing portion 126 is fixed so that the rear end (distal end) of the thread 120 extended from the winding portion 123 does not loosen.
As shown in fig. 4, the winding portion 123 is a portion where a winding (e.g., a portion wound once around the outer periphery of the insertion needle) 123a of the filament 120 and another winding 123b adjacent thereto are wound in close contact with each other, and if the filament is wound between the windings 123a and 123b with almost no gap, the portion of the insertion needle 110 where the winding portion 123 is formed may be configured not to be exposed to the outside. The length L1 (see fig. 3) of the winding portion 123 of the wire inserter 100 may vary depending on the surgical site, and may also vary depending on the degree of skin sagging at the surgical site, the depth and size of wrinkles, and the like.
As shown in fig. 5(a), the fixing portion 126 on the rear end RD side of the thread 120 is a knotted portion type in which the thread 120 itself is connected or adhered to the outer periphery of the insertion needle 110 to form a knotted portion 126a and fix the thread 120, and as shown in fig. 5(b), a fixing ring type in which the thread 120 is fixed by another fixing ring 130 is used. The knotting part type of fig. 5(a) includes a connection type in which a thread is alternately wound around the outer circumference of the insertion needle 110 to form a knotted part 126a, and a bonding type in which adjacent threads 120 are thermally welded or fixed by an adhesive harmless to the human body so that the threads are not loosened in the thread inserter, although not shown in the drawing. In the fixing ring system of fig. 5(b), a knotted portion is not formed behind the wound portion 123, but a separate fixing ring 130 made of sponge, rubber, or the like is inserted to fix the thread 120 to the thread inserter, and the fixing ring 130 is movable in the longitudinal direction of the insertion needle 110 and also rotatable in the outer circumferential direction of the insertion needle 110.
On the other hand, the fixed ring 130 of fig. 5(b) may be used to form the winding portion 123 by rotatably winding the thread around the needle. For example, when the insertion needle 110 and the thread 120 are inserted so as to penetrate the inside of the fixing ring 130, and then the fixing ring 130 is rotated in the outer circumferential direction of the insertion needle 110 and moved in the rear direction RD of the insertion needle 110, the thread 120 inserted inside the fixing ring 130 can be densely wound around the outer circumference of the insertion needle 110 to form the winding portion 123. In the embodiment, the case where the winding portion 123 is formed by the fixing ring 130 is described as an example, but the method of forming the winding portion is not limited to this, and for example, the winding portion 123 may be formed by using a winding device independently.
In fig. 6, a thread burying operation example using the thread inserter in fig. 3 is illustrated, and in fig. 7, a case where a thread is inserted inside a human body according to the thread burying operation example shown in fig. 6 is illustrated.
In fig. 6 and 7, a procedure using the thread inserter of fig. 3 constructed according to an embodiment of the present invention is shown, thereby explaining an example of a thread burying procedure, i.e., a thread inserting method. The leading end of the wire inserter 100 is aligned and inserted into a surgical site where sagging or wrinkles L of the skin S are to be improved, for example, in fig. 6, into the subcutaneous tissue K below the wrinkles L. At this time, the operator may directly insert the insertion needle 110 into the human body without rotating the wire inserter 100. That is, in one embodiment of fig. 3, the winding part 123 is formed so as to firmly wind the filament 120 around the outer circumference of the insertion needle 110 without a gap and not to be pushed backward, and thus the winding part 123 is not pushed to the rear length direction of the insertion needle 110 even if the insertion needle 110 is directly inserted into the human body without physically rotating the insertion needle 110. In addition, during surgery, even if the insertion needle 110 of the wire inserter 100 is repeatedly advanced and retreated in the skin for the purpose of adjusting the insertion path, depth, and the like, the wound portion 123 is not loosened or dropped from the insertion needle 110, but is kept firmly wound, so that the operator can perform surgery at a desired position of the human body with confidence.
After the winding portion 123 is positioned at a desired portion of the human body, as shown in fig. 3 and 4(b), the filament 120 is cut by the sharp distal end portion 113 of the insertion needle 110 by pulling the grip portion 122 of the filament exposed to the rear of the insertion needle 110, and the tension of the winding portion 123 is released, so that the filament is loosened by a predetermined length, and a predetermined gap is formed between the winding portion 123 and the surface of the insertion needle 110, whereby the winding portion 123 can be left in a state of being embedded in the human body, and only the insertion needle 110 can be easily removed from the human body.
A wire inserter 100 in accordance with yet another embodiment of the present invention is illustrated in fig. 8. Comprises an insertion needle 110, a thread 120, an ejector pin 130 for pushing out the thread 120, and a fixing ring 140 for fixing the thread 120 as required.
As shown in fig. 9(a) and (b), the thimble 130 is an elongated needle-shaped member inserted into the rear side through-hole 111 of the insertion needle 110 so as to be able to advance and retreat, and has a grip 131 formed at a rear end portion thereof so as to be easily gripped by a hand. The length of the thimble 130 may be any length as long as the insertion portion 121 of the filament 120 can be pushed out to the tip FD by a desired length. The diameter R of the thimble 130 may be smaller than the inner diameter R of the insertion needle penetration portion 111 but larger than or equal to the diameter R' of the thread 120. (R' is not more than R and R is less than R)
At this time, the thread insertion portion 121 is inserted to a desired length into the distal end portion 113 side of the insertion needle 110 before the grip 112, and the thimble 130 is inserted into the rear RD penetration portion 111 of the insertion needle 110 so as to be positioned behind the thread insertion portion 121 so as to be capable of advancing and retreating.
Fig. 10 is a diagram illustrating an example of a thread burial procedure using the thread inserter shown in fig. 8. After the winding portion 123 is positioned at a desired portion of the human body, if the thimble 130 is advanced toward the distal end side of the insertion needle 110 to push the insertion portion 121 of the thread 120 inserted into the insertion needle 110 by a predetermined length as shown in fig. 9(b), the tension of the winding portion 123 continuing to the insertion portion 121 is released, the predetermined length is released from the outer periphery of the insertion needle 110, a space is generated between the winding portion 123 and the insertion needle 110, and the winding portion 123 is left in a state of being buried in the human body, so that the insertion needle 110 can be simply pulled out.
Thus, the embedded filament 120 is densely wound in a spiral shape and firmly maintained in a state like a tube, and thus has a large amount of filling in the subcutaneous tissue K compared to the conventional filament inserted in the human body in one or more strands, thereby providing a great surgical effect of strengthening muscles or improving sagging or wrinkles of the skin. That is, compared to a conventional silk thread inserted into a human body in one or more strands, the subcutaneous tissue K is stimulated so that a large amount of collagen C is gathered around the silk thread 120 and the periphery of the silk thread 120 is relatively more raised, and the sagging skin S can be made more elastic by the embedded form of the silk thread 120, and wrinkles L can be sufficiently developed.
The thread inserter 100 of the foregoing embodiment inserts the thread 120 into the subcutaneous tissue of the face or the like, tightly pulls the skin or muscle, improves wrinkles or gives elasticity to the skin tissue. Since the thread 120 wound around the outer periphery of the insertion needle 110 of the thread inserter 100 is densely wound without gaps between the winding threads, the thread can be inserted into the human body without rotating the insertion needle 110. Thus, the use of the wire inserter 100 is facilitated. In addition, the filament 120 may be directly inserted into the surgical site in a shape wound around the outer circumference of the insertion needle 110, and the filling effect of the surgical site may be increased. That is, the insertion of the thread 120 into the human body can enhance the operation effect of strengthening the muscle or improving the sagging or wrinkles of the skin. In addition, in order to shorten the time required for the catgut embedding operation and obtain the desired operation effect, the number of operations can be significantly reduced, the pain felt by the operator can be reduced, and the occurrence of side effects after the operation can be minimized.
The present disclosure described above is not limited to the foregoing embodiments and drawings. It is obvious to those skilled in the art to which the present disclosure pertains that various substitutions, modifications, and alterations can be made without departing from the technical spirit of the present disclosure.
