Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and when the description is made with reference to the drawings, the same or corresponding constituent elements are given the same reference numerals irrespective of the reference numerals, and repeated description thereof is omitted.
Fig. 1 and 2 are side views schematically showing a net assembly 10 for cosmetic surgery according to a first embodiment of the present invention, and fig. 3A and 3B are views schematically showing a part of the net assembly 10 for cosmetic surgery according to the first embodiment of the present invention.
Referring to fig. 1-3A and 3B, a first embodiment of a cosmetic surgical mesh assembly 10 of the present invention may generally include a mesh sleeve 100, a core 200, and a protrusion 250. Although not shown, a needle such as a cannula insertion tube or a suture needle may be provided at the distal end of the mesh module 10 for cosmetic surgery, and one or both of the mesh sleeve 100 and the core 200 may be coupled to the needle (not shown).
The mesh sleeve 100 may include a plurality of helical wire members 110, and the plurality of helical wire members 110 may be woven in mutually intersecting directions to form a three-dimensional shape. Of course, wire members other than the helically extending wire members 110 may be included, depending on the desired diameter of the mesh sleeve 100. The mesh sleeve 100 may be basically formed with a passage of a predetermined diameter inside to be formed in a cylinder-like shape. The mesh sleeve 100 may have an outer diameter of 1.8mm to 4.5mm, for example, but the invention is not limited to the diameter of the mesh sleeve 100.
The mesh sleeve 100 may be formed of different materials depending on the application, and in one embodiment of the present invention, the mesh sleeve 100 may be formed of a hydrolyzable material. For example, mesh sleeve 100 may be formed from a material containing Polydioxanone (PDO). Polydioxanone is a biocompatible polymeric material that is decomposed by hydrolysis and most of the resultant is excreted in urine. It is known that polydioxanone generally decomposes and disappears within 6 months and does not cause a foreign body reaction. Similarly, the mesh sleeve 100 may be formed of a material containing one or more polymers of polylactic acid (PLA), poly-L-lactide (PLLA), polycaprolactone (PCL), polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB; polyhydroxybutyrate), poly-D-lactide (poly-D-lactide), and poly-DL-lactide (PDLLA).
The core 200 may extend in one direction and at least a portion of the core 200 may be located inside the mesh sleeve 100, i.e., within the passageway of the mesh sleeve 100. The core 200 may be formed to have a diameter smaller than that of the passage of the mesh sleeve 100. The core 200 may have an outer diameter of 0.4mm to 2.0mm, for example, but the invention is not limited to the diameter of the mesh sleeve 100. In fig. 3A and 3B, the cross-section of the core 200 is depicted as having a generally circular shape, but in some embodiments may be implemented as a more flattened form. Of course, the present invention is not limited to the cross section of the core 200.
The protrusion 250 may be configured to protrude from the outer circumferential surface of the core 200 in a direction inclined to one side. In a preferred embodiment, the protrusions 250 may be formed in a length such that the ends thereof may extend toward the outside of the mesh sleeve 100. That is, the ends of the protrusions 250 may be located outside the mesh sleeve 100 through the spaces 120 formed between the wire members 110 constituting the mesh sleeve 100.
Referring to fig. 3A and 3B, in the mesh assembly 10 of an embodiment of the present invention, the protrusions 250 may be formed at upper and lower portions with reference to the core 200. That is, the protrusions 250 may protrude from the core 200 in only two directions. This allows the core 200 formed with the protrusions 250 to be configured flat. Accordingly, the mesh assembly 10 may be applied so as not to protrude greatly toward the front in a state of being inserted into subcutaneous tissue of a patient unless expanded as needed.
Due to the configuration of the protrusions 250 being inclined toward one side, the net assembly 10 is made difficult to move toward one side as compared to the other side. That is, when the mesh assembly 10 moves toward one side, the end of the protrusion 250 is blocked from moving by being caught by the surrounding tissue, but when it moves toward the other side, the end of the protrusion 250 is not caught by the surrounding tissue, and thus movement is not blocked. In this regard, the needles (not shown) of the mesh assembly 10 may be coupled in a direction opposite to the direction in which the protrusions 250 are inclined.
When the mesh assembly 10 of an embodiment of the present invention is used for suturing or tissue lifting purposes, the protrusions 250 protruding outward of the mesh sleeve 100 may serve to secure the mesh assembly 10 in a desired position. The protrusions 250 firmly attach the mesh assembly 10 to tissue at the surgical site to prevent separation thereof. Thus, when a healthcare worker applies a force to the mesh assembly 10, the mesh assembly 10 effectively pulls on the surrounding tissue.
Since the mesh sleeve 100 is formed by braiding a plurality of wire members 110, it can withstand much higher tension than general wires. In addition, the mesh sleeve 100 is formed in a three-dimensional shape by the wire members 110, and the space 120 between the wire members 110 occupies a large area, so that when tissue is regenerated at a surgical site, the mesh sleeve 100 grows inward of the mesh sleeve 100, and the mesh sleeve 100 can be integrated to the surgical site. When the mesh sleeve 100 is formed of a hydrolyzable material, it may be decomposed and removed in the body, and when the mesh sleeve 100 is not formed of a hydrolyzable material, it may remain in the body as an implant.
On the other hand, as shown in fig. 2, in the mesh sleeve 100 of an embodiment of the present invention, the mesh sleeve 100 may be expanded to be used. Since the mesh sleeve 100 is formed by braiding the wire members 110, the middle portion of the mesh sleeve 100 can be inflated and expanded when pressurized from one side and the other side. This may be accomplished, for example, by pressing one side of the mesh sleeve 100 after the other side of the mesh sleeve 100 is snapped onto one of the protrusions 250. The expanded configuration of mesh sleeve 100 may act as an implant in this region. In some embodiments, a functional agent such as a filler may be injected into the inside of the mesh sleeve 100.
Fig. 4 is a cross-sectional view schematically illustrating a portion of a mesh assembly 20 for cosmetic surgery according to a second embodiment of the present invention. The net assembly 20 for cosmetic surgery of the second embodiment of the present invention has in common a plurality of points with the net assembly 10 for cosmetic surgery of the foregoing first embodiment. Hereinafter, description will be made centering on differences of the mesh assembly 20 of the second embodiment. The features described with respect to the first embodiment may be applied to the second embodiment, and similarly, the features described with respect to the second embodiment may also be applied to the first embodiment. Some reference numerals mentioned in describing the second embodiment are intended to refer to constituent elements corresponding to those to which the corresponding reference numerals are applied in the first embodiment.
Referring to fig. 4, the cosmetic surgical mesh assembly 20 of the second embodiment of the present invention may generally include a mesh sleeve 100, a core 200, protrusions 250, and a cover film 310. Since the mesh sleeve 100, the core 200, and the protrusions 250 are substantially the same as those described in the first embodiment, duplicate description will be omitted.
The cover film 310 corresponds to the part that binds the protrusions 250 between the mesh sleeve 100 and the core 200. The cover film 310 may prevent the protrusion 250 from protruding to the outside of the mesh sleeve 100 by surrounding the protrusion 250, and may be located inside the passage of the mesh sleeve 100. In the embodiment shown in fig. 4, the cover film 310 is implemented in such a manner as to be spirally wound around the core 200, and the protrusions 250 are bound in such a manner that the protrusions 250 are in contact with the core 200.
As described with respect to the first embodiment, the protrusions 250 of the mesh assembly 10 are formed to protrude toward the outside of the mesh sleeve 100 and to be inclined toward one side, so that they can be caught to the peripheral tissue to achieve firm coupling, and can also be used to fix the other side end of the mesh sleeve 100 when expansion of the mesh sleeve 100 is required. On the other hand, since the protrusion 250 formed on the core 200 has a shape inclined in one side direction, the movement of the net assembly 10 to the other side is not hindered, but may be hindered. Therefore, attention is required to dispose the mesh assembly 10 at a necessary position because if it is moved further in the other direction beyond the necessary position, it is difficult to move the mesh assembly 10 in the one direction to adjust the position.
The net assembly 20 for cosmetic surgery of the second embodiment of the present invention further includes a cover film 310, so that the protrusions 250 can be prevented from interfering with the movement of the net assembly 20 until necessary. The medical staff using the mesh assembly 20 can insert the mesh assembly 20 into the operation site in a state where the cover film 310 is disposed above the protrusions 250 between the mesh sleeve 100 and the core 200, and can remove the cover film 310 when the mesh sleeve 100 and the core 200 are disposed to a necessary position.
Since the cover film 310 is spirally wound, a medical person can separate the cover film 310 by holding the end of the cover film 310 and rotating it around the core 200. As the cover film 310 is removed, the protrusions 250 protrude to the outside of the mesh sleeve 100 and are caught in the tissue around the mesh assembly 20, so that a firm coupling can be achieved.
Fig. 5 and 6 are cross-sectional views exemplarily showing a part of a net assembly 30 for cosmetic surgery according to a third embodiment of the present invention. The mesh assembly 30 for cosmetic surgery of the third embodiment of the present invention has a plurality of common points with the mesh assembly 10 for cosmetic surgery of the first embodiment and the mesh assembly 20 for cosmetic surgery of the second embodiment. Hereinafter, description will be made centering on differences of the mesh assembly 30 of the third embodiment. Features described in relation to the first or second embodiment may be applied to the third embodiment, and similarly features described in relation to the third embodiment may also be applied to the first and second embodiments. Some reference numerals mentioned in describing the third embodiment are intended to refer to constituent elements corresponding to the constituent elements to which the corresponding reference numerals are applied in the first and/or embodiments.
Referring to fig. 5 and 6, a net assembly 30 for cosmetic surgery according to a third embodiment of the present invention may generally include a net sleeve 100, a core 200, a protrusion 250, and a cover film 320. Since the mesh sleeve 100 is substantially the same as that described in the first embodiment, a repetitive description will be omitted.
In the net assembly 30 of the third embodiment of the present invention, the cover film 310 may be formed in a tube shape surrounding the core 200 as shown in fig. 6. With the protrusion 250 and the core 200 positioned inside the cover film 320 having a predetermined width, the protrusion 250 is abutted against the core 200 so as not to protrude to the outside of the mesh sleeve 100 and not to interfere with the movement of the mesh assembly 30. The medical staff using the mesh assembly 20 can insert the mesh assembly 30 into the surgical site in a state where the cover film 320 is disposed above the protrusions 250 between the mesh sleeve 100 and the core 200, and can remove the cover film 320 when the mesh sleeve 100 and the core 200 are disposed to a necessary position.
Since the cover film 320 is tubular around the core 200 and the protrusions 250, a healthcare worker can peel the cover film 320 from the core 200 by grasping and pulling the end of the cover film 320. As the cover film 320 is removed, the protrusions 250 protrude to the outside of the mesh sleeve 100 and are caught in the tissue around the mesh assembly 30, so that firm coupling can be achieved.
As shown in fig. 5, in the mesh assembly 30 of the third embodiment of the present invention, the end of the protrusion 250 may be formed with a spike 252 on the inner side thereof and a bent portion 254 on the outer side thereof. The spike 252 may form a sharp point or linear edge and the bend 254 may form a gentle curve. In addition, in a state where the protrusion 250 is abutted against the core 200, the connection portion 256 between the protrusion 250 and the core 200 may be gently curved as well.
On the other hand, a receiving groove 202 may be formed in the core 200. The receiving groove 202 may be concavely formed at a position spaced apart from the connection portion 256 of the protrusion 250 by the protruding length of the protrusion 250, and may be configured such that the spike 252 of the front end portion of the protrusion 250 is inserted when the protrusion 250 is abutted against the core 200.
Referring to fig. 6, in a state where the cover film 320 surrounds the core 200 and the protrusion 250 in a tubular shape, the spike 252 of the protrusion 250 may be inserted into the receiving groove 202 formed in the core 200, and only the bent portion 254 of the outer side of the protrusion 250 may be directed to the outer side. Since the connection portion 256 and the bent portion 254 of the protrusion 250 face outward and are in contact with the cover film 320, and the spike portion 252 of the protrusion 250 is not in contact with the cover film 320, the cover film 320 can be easily moved without being caught when the medical staff pulls the cover film 320.
When the cover film 320 is pulled to peel around the protrusions 250, the protrusions 250 may extend outward as shown in fig. 5 to the outside of the mesh sleeve 100 and may firmly bond to the tissue surrounding the mesh assembly 30. In order to make the protrusions 250 more easily protrude to the outside, the pitch (pitch) of the spiral wire members 110 constituting the mesh sleeve 100 may be proportional to the pitch of the protrusions 250.
In some embodiments of the present invention, the cover film 320 may be formed of a hydrolyzable or dissolvable material, or the protrusions 250 may be caused to protrude outwardly as the cover film 320 is decomposed or dissolved at the surgical site after insertion of the mesh assembly 30 by a medical practitioner.
Fig. 7 is a side view schematically illustrating a portion of a mesh assembly 40 for cosmetic surgery according to a fourth embodiment of the present invention. Referring to fig. 7, in addition to any one of the aforementioned mesh assemblies 10, 20, 30 for cosmetic surgery of the first to third embodiments, the mesh assembly 40 for cosmetic surgery of the fourth embodiment of the present invention may further include a needle 400. That is, the cosmetic mesh assembly 40 may include a mesh sleeve 100, a core 200, cover films 310, 320, and a needle 400.
When one direction in which the core 200 extends is referred to as a first direction, the needle 400 may extend in the first direction and a passage space 420 may be formed therein. In this specification, the term needle 400 is not limited to a syringe needle, but encompasses all kinds of tools having a channel space 420 on the inside, including cannula insertion tubes, suture needles, catheters, etc.
The passage space 420 may pass from an opening 430 at a rear end of the needle 400 to an opening 440 at a front end of the needle 400. As shown in fig. 7, the mesh sleeve 100, the core 200, and the cover films 310, 320 may be inserted into the passage space 420 of the needle 400. The mesh sleeve 100, the core 200, and the cover films 310 and 320 may be inserted so as to enter the opening 430 on the rear end side of the passage space 420 and pass through the opening 440 on the front end side or behind the opening 440. The rear end of the needle 400 may also be provided with a connector 500 for convenience of use.
Fig. 8 and 9 exemplarily show a needle 400A of the mesh assembly 40 for cosmetic surgery, which can be applied to an embodiment of the present invention. According to an embodiment of the invention, needle 400A may include a compression portion 450. The term compressed portion 450 is used herein to describe the shape of the needle 400A and is not actually intended to be formed by compressing the body 410 of the needle 400A.
When the direction in which the needle 400 extends is referred to as a first direction, the direction orthogonal to the first direction is a second direction, and the direction orthogonal to both the first direction and the second direction is a third direction, in the compressed portion 450, the body 410 of the needle 400 is compressed in the second direction so that the cross section thereof may have a reduced width in the second direction and may have a conversely increased width in the third direction.
In the mesh assembly 40 of an embodiment of the present invention, since the protrusions 250 are formed to protrude from the core 200, the width of the cross section of the core 200 including the protrusions 250 in a specific direction (i.e., the third direction) is greater than the width in the other direction (i.e., the second direction). If the passage space 420 of the needle 400 maintains a circular cross-section with an increased inner diameter to accommodate the mesh sleeve 100 and the core 200 therein, the overall diameter of the needle 400 may be excessively large, which may form an increased size hole at the site of the patient's operation to increase the likelihood of scarring.
When the compressed portion 450 is formed on the needle 400 as in one embodiment of the present invention, the cross section of the passage space 420 has a reduced width in the second direction and an increased width in the third direction, and thus is suitable for accommodating the core 200 having a smaller width in the second direction and a larger width in the third direction. In one embodiment of the invention, the compressed portion 450 may actually be formed by compressing a portion of a needle of a basic configuration, such as an 18 gauge needle.
In the example shown in fig. 8 and 9, a plurality of compressed portions 450 are formed in the needle 400. The location and number of compressed portions 450 may be varied as desired. On the other hand, the front end 412 of the needle 400 is rounded, including only a smooth curved surface without sharp edges. An opening 440 at the front side of the passage space 420 may be formed at a side surface of the front end portion 412.
Fig. 10 and 11 exemplarily illustrate another needle 400B of the mesh assembly 40 for cosmetic surgery, which can be applied to an embodiment of the present invention. In the needle 400B shown in fig. 10 and 11, the compressed portion 450 is formed on a large portion of the body 410 of the needle 400, and the compressed portion 450 extends to the front-side opening 440. In the needle 400B shown in fig. 10 and 11, the rear end portion of the body 410 of the needle 400 is maintained in an uncompressed state, but in some embodiments, the compressed portion 450 may be formed on the entire body 410 of the needle 400 including the portion.
Fig. 12 and 13 exemplarily show another needle 400C of the mesh assembly 40 for cosmetic surgery, which can be applied to an embodiment of the present invention. In the needle 400C shown in fig. 12 and 13, the front end portion 414 of the needle 400 is formed in a form having a cross-sectional surface, and the opening 440 of the front side of the passage space 420 is formed on the cross-sectional surface of the front end portion 414. This configuration has the advantage of allowing the compressed portion 450 to be attached to the front end 414.
Fig. 14 and 15 are side views exemplarily showing a part of a mesh assembly 50 for cosmetic surgery according to a fifth embodiment of the present invention. Referring to fig. 14 and 15, in addition to any one of the aforementioned mesh assemblies 10, 20, 30 for cosmetic surgery of the first to third embodiments, the mesh assembly 50 for cosmetic surgery of the fifth embodiment of the present invention may further include needles 600, 610. That is, the cosmesis mesh assembly 50 may include a mesh sleeve 100, a core 200, cover films 310, 320, and needles 600, 610.
At least one of the mesh sleeve 100 and the core 200 may be coupled at an end of the needle 600. That is, the front end portions of both the mesh sleeve 100 and the core 200 may be coupled to the rear end of the needle 600, but there may be cases where only the mesh sleeve 100 is coupled to the needle 600, or only the core 200 is coupled. The needles 600, 610 may have a variety of shapes as desired. For example, in fig. 14, needle 600 has a curved shape like a suture needle; in fig. 15, the needle 610 has a straight shape like a basic needle. The needle 610 of fig. 15 may have a length of about 100mm to 400 mm.
On the other hand, as shown in fig. 15, in the mesh assembly 50 for cosmetic surgery of the fifth embodiment of the present invention, the needles 600, 610 may be coupled to both side ends of the mesh sleeve 100 and the core 200. For example, the mesh sleeve 100 and the core 200 may extend the same length, and the needles 600, 610 may be coupled to both side ends of the mesh sleeve 100 and the core 200, respectively.
Fig. 16 is a side view schematically illustrating a portion of a mesh assembly 60 for cosmetic surgery according to a sixth embodiment of the present invention. Referring to fig. 16, the mesh assembly 60 for cosmetic surgery of the sixth embodiment of the present invention may include the mesh sleeve 100 and the needles 400, 600, 610 while omitting the core 200, the protrusions 250, and the cover films 310, 320. In this case, the needle 600 may be a suture needle having a curved shape, and the mesh sleeve 100 may be used instead of the suture.
According to the embodiments of the present invention set forth hereinabove, the mesh assembly 10, 20, 30, 40, 50, 60 has much higher strength than general surgical wires and can be firmly bonded to the surgical site with higher strength, thereby providing higher availability in the surgical procedures of tissue lifting and the like.
The mesh assembly of an embodiment of the present invention can more finely adjust the position where the protrusions 250 protruding to the outside of the mesh sleeve 100 are coupled to the peripheral surgical site tissue, so that the success rate of the surgery can be significantly improved.
Although the invention has been described hereinabove with reference to one embodiment thereof, it will be understood by those skilled in the art that various modifications and changes may be made thereto without departing from the spirit and scope of the invention as set forth in the following claims.
