Description

Thread Structure for Surgery

The present invention relates to a surgical thread structure.

In addition to surgically correcting or restoring deformed or unsightly parts of the body, it is a method of improving skin sagging or wrinkles due to deterioration of elasticity due to aging of the skin on the face and neck during cosmetic surgery. A method of alleviating wrinkles by inserting an implant made of silicone or plastic tube into the tissue and pulling it, or pulling the sagging skin tissue using a thorn thread or a surgical mesh is used.

However, since the prosthesis is difficult to adhere to the surrounding skin tissue, the durability is weakened over time, so that the elasticity of the skin may return to its original state, and a problem of foreign body feeling and pain may occur.

In the case of using a thorn thread as in Korean Utility Model Publication No. 20-0320005, the sagging or sagging tissue is pulled by lifting it by hanging the thread on a specific skin tissue. And, it was difficult to adhere to the tissue, so there was a problem in that the support and fixation power were lowered.

In order to solve this problem, Korean Patent Publication No. 10-1432268 and Korean Patent Publication No. 10-1182337 use a mesh to adhere to the skin tissue to improve support and fixation power, but the mesh adhered to the skin tissue is also time-consuming. As time passes, support and fixation power are lowered by muscle movement, etc., so it is still difficult to maintain the continuity of the pulling effect.

In particular, in the past, after pulling the sagging or sagging skin tissue using the thorn thread or mesh as above, it is fixed to the skin tissue again to maintain the pulled state, or the extended thread is sutured to the temporal muscle or fascia through the face. However, in the case of fixing to the skin tissue, the continuity of the pulling effect as above is a problem, and the method of suturing to the temporal muscle or fascia has a problem that an additional scar may occur and/or pain persists.

The present invention has been devised to solve the above problems, in which a fixing member including a plurality of protrusions and a plurality of adhesions is fixed to the periosteum with little movement, and the elevating member fixed to sagging or sagging skin tissue is pulled in a pulled state. An object of the present invention is to provide a thread structure for surgery that can provide support, can firmly fix and/or maintain a pulled state even over time, and minimize pain after surgery.

One embodiment of the present invention, the elevating member; and one or more fixing members connected to the elevating member to support the elevating member and comprising two fixed chambers in which a plurality of first protrusions are formed and a plurality of first adhesion portions formed between the two fixed chambers; Including, wherein the fixing member provides a thread structure for a longer length than the elevating member.

According to the present invention, not only can the fixing member including a plurality of protrusions be firmly fixed to the periosteum, but also the periosteum and/or surrounding tissues adhere to the plurality of adhesions formed between the two fixing chambers of the fixing member. Thus, the fixing member can be uniformly fixed to the periosteum tissue. Accordingly, it is possible to prevent the phenomenon that the elevating member fixed for the purpose of pulling sagging or sagging skin loses support or fixation power and sags again, thereby maintaining the lasting power for a long time.

In addition, as the fixing member is fixed to the periosteum with little movement, the present invention has superior support and/or fixing power compared to surgical members that are fixed to the sagging or sagging skin tissue after raising the existing sagging or sagging skin tissue. And, compared to the method of suturing the extended thread with the muscle or muscle membrane after being raised from the skin tissue, the surgical thread structure of the present invention can be firmly fixed to the periosteum without separate sutures, so it has excellent support and/or fixation power. and to minimize discomfort and/or pain.

Hereinafter, the present invention will be described in detail.

The present invention provides a surgical thread structure.

Conventionally, after elevating the sagging or sagging skin tissue using a surgical thread or mesh, the remaining thread or mesh portion is fixed to the sagging or sagging skin tissue, or a thread extended to the surgical thread or mesh In the case of fixing to the skin tissue, the holding power or fixing power weakened after a period of time, so the continuity of the pulling effect was a problem. There was a problem that caused a problem, and there was a problem that the support or fixation power was weakened according to the movement of the muscle.

Accordingly, the surgical thread structure of the present invention, designed to solve the above problems, has excellent support and/or fixing power because the fixing member including the protrusion and the adhesion part can be firmly fixed to the periosteum and/or the surrounding tissue, and separately The patient's pain can be minimized because sutures are not required, and as one or two or more fixing members including two fixing chambers are independently connected to the elevating member, the flexibility or bendability of the fixing member is increased, so that the periosteal membrane as described above. And / or it can be fixed to the surrounding tissue, there is an advantage of excellent workability during surgery. In this case, the periosteum and/or the surrounding tissues may refer to the temporal region adjacent to the upper part of the ear as shown in FIG. 12 .

The surgical thread structure of the present invention, the elevating member; and one or more fixing members connected to the elevating member to support the elevating member and comprising two fixed chambers in which a plurality of first protrusions are formed and a plurality of first adhesion portions formed between the two fixed chambers; Including, the fixing member may have a longer length than the elevating member.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, as shown in FIG. 1 , the fixing chamber 1 included in the fixing member includes a first protrusion 2 protruding obliquely from the surface of the fixing chamber 1 along the longitudinal direction of the fixing chamber. can do. The first protrusion 2 may protrude from the surface of the fixing chamber 1 in the longitudinal direction of the fixing chamber 1 to be inclined toward the elevating member (see FIGS. 8 and 13 ).

That is, after the elevating member lifts the face with a force against gravity, the first protrusion 2 formed in the fixing chamber 1 connected to the elevating member receives a force corresponding to the frictional force against gravity, and the lift is It may protrude to be inclined toward the elevating member so as to support the member.

The distance L between the plurality of first protrusions 2 formed in the fixed chamber 1 may be 1 mm to 20 mm, but is not limited thereto, and the fixed chamber according to the type of the elevating member and the condition of the patient. The number can be adjusted by adjusting the spacing between the plurality of first protrusions 2 formed in (1). At this time, when the distance between the first protrusions is less than 1 mm, the size of the first protrusions is small and cannot fulfill the function of being fixed to the periosteum. It may not be fixed to the pole and may be bent, which may cause a problem in fixing force.

In addition, the cross section of the fixing chamber 1 may be a circular shape, a distorted circular shape, an elliptical shape, or a polygonal shape, but is not limited thereto. When the cross-section of the fixed chamber 1 is circular, distorted, or oval, the first protrusion 2 may be formed on any surface of the fixed chamber 1, and the fixed chamber 1 is In the case of a polygon, the first protrusion 2 may be formed on one surface of the polygon or a vertex portion of the polygon of the fixing chamber 1 to increase the fixing force.

At this time, the plurality of first protrusions 2 may be formed on a part of the other surface of the fixed chamber 1 opposite to one surface of the fixed chamber 1 on which the first protrusion is formed, or the plurality of first protrusions 2 . The first protrusion 2 may be formed in a spiral shape along the surface of the fixing chamber 1 , but is not limited thereto.

The fixed chamber 1 may have an average diameter (D) or an average diameter (D) of a diameter passing through the outer center of the polygonal cross section of 0.1 mm to 5 mm, or 0.1 mm to 1 mm. The average diameter of the fixed chamber 1 or the average of the diameter passing through the outer center of the polygon may be measured through the cross section of the fixed chamber 1 . When the average diameter of the fixing chamber 1 or the average diameter passing through the outer center of the polygonal cross section satisfies the above range, even if the fixing member is fixed to the periosteum of the temporal region, there is little feeling of foreignness or foreignness.

In this case, the first protrusion 2 may be formed by cutting to be inclined from the surface of the fixing chamber 1 . Alternatively, the first protrusion 2 may be separately processed and attached to the surface of the fixed chamber 1 .

At this time, the cutting may be performed using a knife or a laser, but is not limited thereto. Alternatively, when manufacturing the fixed chamber 1, the raw material may be put into a mold made in the shape of the first protrusion, etc., and may be manufactured by heating, compression, and/or molding, but is not limited thereto.

When the cutting is used, a groove of a predetermined depth may be formed in the fixing chamber 1 , and a cut part of the fixing chamber 1 formed by the groove protrudes to the outside to form the first protrusion 2 . may be doing If the cutting method is used, there is an effect that the fixed chamber 1 including the plurality of first protrusions 2 can be manufactured in a simple and quick way without a separate additional process.

As shown in FIG. 3 , the cutting depth h of the first protrusion 2 is 10% to 50% of the average diameter D of the fixed chamber 1 or the diameter D passing through the outer center of the polygonal cross section. It can be %. When the cutting depth h of the first protrusion 2 is less than 10% of the average diameter of the fixing chamber 1 or the diameter passing through the outer center of the polygonal cross-section, the first protrusion does not protrude sufficiently, so that the periosteum and/or its There is a problem in that the fixation force fixed to the surrounding tissue is lowered, and when it is more than 50%, the strength of the first protrusion is weakened, and a problem of being bent (removed) in the opposite direction (that is, the direction in which the first protrusion receives a force) may occur. have.

Also, as shown in FIG. 3 , the cutting angle a of the first protrusion 2 may be 10° to 45° from the surface of the fixing chamber 1 . When the cutting angle (a) of the first protrusion is less than 10°, the size of the first protrusion is reduced or the thickness is thin, so that the function of being fixed to the periosteum cannot be fulfilled, and the cutting angle (a) of the first protrusion is 45 If it exceeds °, the first protrusion may not be fixed to the periosteum and may be bent, resulting in a problem in fixing force.

The fixed chamber (1) is polydioxanone (Polydioxanone (PDO)), polyglycolic acid (Polyglycolic acid (PGA)), polylactic acid (Polylactic acid (PLA)), polyvinyl alcohol (Polyvinylalcohol (PVA)), or It may be prepared as a component such as a mixture thereof, but is not limited thereto, and as long as it is known as a biocompatible component harmless to the human body, it may be used without limitation.

As shown in FIG. 2 , the fixing member 10 includes two fixing chambers 1 , and a plurality of first adhesion parts 3 may be formed between the two fixing chambers 1 .

The first adhesion part 3 may be formed including a space surrounded by the two fixing chambers 1 and two adjacent connection parts 4 connecting the two fixing chambers 1 .

At this time, the average distance d between the two fixing chambers 1 may be 0.1 mm to 5 mm. The average distance (d) between the two fixed chambers (1) may mean the shortest distance between the centers of the cross-sections of the two fixed chambers (1), or the two fixed chambers (1) at any point It may mean an average after measuring the distance between them three or more times. However, the portion from the part where the two fixing chambers 1 are joined at one end to the connection part adjacent to the joined part is excluded from the average distance (d) measurement, and the distance between the two fixing chambers 1 is excluded. It may be to measure the average distance (d).

The connection part 4 may be formed of a thread having the same shape or material as that of the fixed chamber 1 , and the connection part 4 may include one or more connection threads, and the connection part 4 has two In the case of including more than one connection chamber, two or more connection chambers may be in contact with each other or may be separated from each other and independently connected to the fixed chamber, and two or more connecting chambers may be separated from each other and independently connected to the fixed chamber The distance between the two or more connection chambers may be 0.1 mm to 5 mm, but is not limited thereto. In addition, when the connecting portion includes two or more connecting chambers, the internal space between the two or more connecting chambers may play the same or similar role as that of the first coalescing unit.

The spacing between the plurality of connection parts 4 (ie, the spacing between any connection part and an adjacent connection part) may be 10 mm to 30 mm. As described above, the first coalescence portion 3 is formed including a space surrounded by the two fixed chambers 1 and a plurality of connecting portions 4 connecting the two fixed chambers 1, The fixing member 10 can be firmly adhered to the periosteum and/or the surrounding tissue through the dog's first adhesion part 3, so that the pulling effect of the elevating member fixed to the skin tissue to elevate the sagging or sagging skin tissue is reduced. can be maintained continuously.

In addition, as shown in FIG. 2 , the connection part 4 is provided in plurality, so that as the first coalescence part 3 is formed in plurality, the fixing member forms a coalescence space according to the first coalescence part 3 . Adhesion may occur more easily between the periosteum and/or its surrounding tissues through the adhesion space, and also between the periosteum and/or its surrounding tissues through the adhesion space, resulting in more stable fixation for a long time.

One end of the fixing member 10 may be to which the two fixing chambers 1 are joined. That is, as shown in FIG. 2 , the two fixing chambers 1 may be joined at the end of the fixing member 10 , which is not a portion connected to the elevating member. When the two fixing chambers 1 are joined as described above, it may be easy to fix the fixing member 10 to the periosteum by hooking the fixing member 10 to the insertion member and then inserting it into the body. .

After the fixing member 10 is inserted into the body and fixed to the periosteum and/or the surrounding tissue, a portion of the fixing member 10 including one end to which the two fixing chambers are joined is exposed outside the body. (The length of the part exposed to the outside may be different depending on the patient), and the part exposed outside the body may be finally cut and removed without a separate suturing or tying process.

The insertion member may be used without limitation as long as it is a surgical member (equipment or tool) for inserting the fixing member 10 into the body, and may be, for example, a surgical needle, but is not limited thereto.

4 to 7 are views showing a surgical thread structure according to an embodiment of the present invention, and FIGS. 13 to 16 are photographs of a surgical thread structure according to an embodiment of the present invention ( FIGS. 4 to 7 ) corresponds to FIGS. 13 to 16, respectively).

4 to 7 , the fixing members 10 , 11 , 12 , and 13 may be longer than the elongated members 20 , 21 , 22 and 23 .

For example, the fixing members 10, 11, 12, and 13 may be 1.2 to 4 times the length of the elevating members 20, 21, 22, 23, and specifically, 2 to 3 times the length of the elevating members 20, 21, 22, and 23. can When the length of the fixing members 10, 11, 12, 13 satisfies 1.2 to 4 times the length of the elevating members 20, 21, 22, and 23, the elevating member lifts the sagging or sagging skin tissue. The fixing member connected to the elevating member can be fixed to the periosteum and/or its surrounding tissue, not to the skin tissue, and ultimately stretched after elevating the existing sagging or sagging skin tissue. It has superior support and/or fixation power compared to surgical members fixed to skin tissue without sagging or sagging, and can minimize discomfort and/or pain.

Specifically, the length of the fixing members 10, 11, 12, 13 may be 12 cm to 20 cm, or 15 cm to 20 cm. The length of the elevating members 20 , 21 , 22 , and 23 may be 5 cm to 10 cm, or 6 cm to 9 cm. When the length of the fixing member 10,11,12,13 and the length of the elevating member 20,21,22,23 satisfy the above range, the elevating member 20,21,22,23 is It is used to fix sagging or sagging skin tissue, and the fixation members 10, 11, 12, 13 can be fixed to the periosteum and/or surrounding tissue other than the skin tissue, thereby providing support and/or The fixation force can be excellent.

Conventionally, both elevation and fixation were performed only within the skin tissue of the face part using a surgical thread or mesh, but the surgical thread structure of the present invention satisfies the length conditions of the fixing member and the elevation member as described above, It is fixed to the elevator member and can expand the area where sagging or sagging skin tissue is pulled, so that the pulling effect can be increased more conspicuously. It can be fixed and adhered to the periosteum and/or its surrounding tissues, and in addition, there is an effect of maintaining durability for a long time without pain.

Specifically, as shown in FIG. 12 , the surgical thread structure of the present invention is raised using an elevating member in the skin tissue of the face part, and the periosteum of the temporal region for fixing the elevating member elevating the sagging or sagging skin tissue. And/or by using a fixing member that can be fixed to the surrounding tissue, the surgical thread structure can be fixed to the periosteum and/or surrounding tissue as well as the skin tissue of the facial part to provide excellent support and/or fixation force. .

As described above, since the temporal region adjacent to the upper part of the ear is relatively close to the outer skin (outermost skin surface) compared to other parts (for example, the facial part) with a periosteum, the surgical thread structure is inserted at the same depth. In this case, the fixing member, which is longer than the elevating member, may be fixed to the periosteum and/or surrounding tissue of the temporal region.

Therefore, in the surgical thread structure of the present invention, the fixing member is configured to be longer than the length of the elevating member, and the fixing thread is used for flexibility, but the first coalescence using two fixing chambers for forming the coalescing part for strong fixing. By forming the part, it is possible to fix the fixing member to the periosteum of the temporal region with little movement without raising and fixing the skin tissue or muscle tissue as in the prior art, so that the state in which the elevation member pulls the skin tissue is fixed and fixed for a long time. It is excellent in preventing the phenomenon from sagging again over time by maintaining / or maintaining it.

In addition, the surgical thread structure of the present invention can be used by adjusting the number of the fixing members according to the shape, size, etc. of the elevating member.

For example, as shown in FIGS. 4 or 7 and 9 to 11 , only one fixing member 10 , 11 , 14 , 15 , 16 is attached to the elevating member 20 , 21 , 24 , 25 , 26 . Even when connected, the ability to support and fix the elevating members 20, 21, 24, 25, 26 is sufficient, and as shown in FIGS. 5 and 6, the shape or size of the elevating members 22 and 23 is changed. In this case, by using two or more fixing members 12 and 13 connected to the elevating members 22 and 23 , the ability to support and fix the elevating members 22 and 23 may be increased.

In this case, the two or more adjacent fixing members may be formed so as not to contact each other. The two or more adjacent fixing members may be independently connected to the elevating member without contacting each other.

The fixing member is configured to include two fixing chambers, and when the fixing member is composed of two or more plurality of fixing members, since the two or more adjacent fixing members are independently connected to the elevating member without contacting each other, the fixing member has the advantage that it is easy to adjust the position and/or direction of the fixing member due to its excellent flexibility or bendability, so it can be fixed to the periosteum according to various types of facial structures and/or temporal structures of the patient to maximize the fixing force. have. In particular, the above effect can be maximized when the average distance d between the two fixed chambers is 0.1 mm to 5 mm.

That is, when the two or more fixing members are each independently connected to the elevating member, it is easy to connect the fixing members to the insertion member and fix them to the periosteum, and in addition, the elevating member is attached to the skin tissue of the face. After insertion, it is easy to change the fixation member in various directions without movement of the elevating member, so that it is considerably easier to adjust the position of the periosteum to fix the fixation member in the patient's temporal region, and ultimately, the fixation There is an advantage that the member can be fixed in the most optimized condition according to the condition and/or shape of the patient's face or temporal region.
