Description

  The present invention relates to a forming treatment thread, particularly a forming treatment thread suitable for a treatment for removing sagging skin or wrinkles, and a forming treatment method using the forming treatment thread.

  Conventionally, yarns made from synthetic fibers such as polyester and nylon, which have been used in surgical operations, have been used as forming treatment yarns. These forming surgical threads have the advantages of high tensile strength and little tissue reaction in the body, and are also suitably used in forming procedures such as suturing a desired part of the human body.

  There are various types of plastic surgery, such as tightening the skin such as the face, chest, and buttocks to remove sagging skin or wrinkles (hereinafter also referred to as “wrinkles etc.”). In such treatment, a thread and needle for forming treatment are used, and the thread is guided into the body by piercing the needle through the desired site, and then the skin at the desired site is pulled up. Or the treatment which pulls up meat and removes wrinkles etc. is given.

  As the yarn for forming treatment, not only the yarn for surgical operation made of synthetic fibers such as polyester and nylon is used as it is, but also the yarn for forming treatment having a specific shape is used. As this specific shape, for example, it is a shape in which a barb with different resistance is formed in the pulling direction and the pulling back direction.

  In the case of a forming surgical thread having such a specific shape, when the thread is pulled up after the thread has been inserted through the surgical site, it is easy to draw the skin or meat around the thread by this return, and wrinkles, etc. It can be effectively removed.

  However, even if it is a yarn for forming treatment having such a specific shape, if the material is synthetic fiber such as polyester or nylon, its elasticity is insufficient, so the elasticity of the treatment site after treatment In some cases, the performance may be reduced, or the treatment site may lack the inherent flexibility. Moreover, there exists a possibility that an unnatural form may be provided to a treatment site | part because it pulls more than necessary.

  Therefore, a material having elasticity that is easy to assimilate to the elasticity of the human body, which can maintain the elasticity of the treatment site even after the plastic surgery, can maintain the natural shape without causing any pulling. It is an object of the present invention to provide a forming treatment method that removes sagging skin, wrinkles, and the like by providing the formed forming treatment thread and using a suitable forming treatment needle.

  Another object of the present invention is to further impart a cosmetic effect to the treatment site by applying or penetrating specific amino acids and / or cytokines to the forming treatment thread.

The forming surgical thread of the present invention is a forming surgical thread formed by continuously forming a barb having a small resistance in the pulling direction and a large resistance in the pulling direction on the yarn body,
It is characterized by being made of a stretchable material.

  The yarn body has a reverse turn with a large resistance in the pulling direction and a small resistance in the pulling direction, and a reverse turn with a small resistance in the pulling direction and a large resistance in the pulling direction. It may be formed in both directions.

  The stretchable material is preferably at least one selected from the group consisting of silicone, natural rubber, synthetic rubber, formalized polyvinyl alcohol, polypropylene, polyurethane, and polytetrafluoroethylene.

  The forming surgical thread of the present invention may further be coated or infiltrated with amino acids and / or cytokines, and these amino acids are valine, leucine, isoleucine, alanine, arginine, glutamine, glutamic acid, aspartic acid, proline, cysteine, Desirably, it is at least one selected from the group consisting of glycine, serine and lysine.

  The forming treatment method of the present invention forms the inside of the needle body in a hollow shape and cuts both end portions of the needle body obliquely to form a piercing portion, and closes one of the piercing portions, The forming surgical thread of the present invention is passed through the hole formed in the needle body of the forming surgical needle formed by opening the other piercing portion to the outside, and the forming surgical needle is inserted into the surgical site in the human body. Then, after inserting the forming operation thread into a predetermined shape, fixing the end of the forming operation thread, and then pulling up the forming operation thread, sagging of the skin at the operation site or wrinkles It is characterized by removing.

  According to the forming surgical thread of the present invention, elasticity can be maintained semipermanently even after the treatment at a desired treatment site, and a natural form can be maintained without causing any pulling. .

In addition, by using the forming treatment thread and a suitable treatment needle, a forming treatment excellent in the effect of removing wrinkles and the like can be easily performed.
Furthermore, by using a thread for forming treatment in which specific amino acids and / or cytokines are applied or infiltrated, the skin at the treatment site can be activated, aging can be reduced and a cosmetic effect can be imparted.

Next, the forming treatment thread and the forming treatment method of the present invention will be described in detail with reference to the drawings with examples.
<Formation treatment thread>
The forming surgical thread of the present invention (hereinafter also referred to as “the surgical thread of the present invention”) has a specific shape and is formed using a stretchable material.

  The specific shape refers to a shape formed by continuously forming a barb having a small resistance in the pulling direction and a large resistance in the pulling direction on the forming treatment thread main body. By having such a shape, when pulling up the thread after inserting the thread into the treatment site, it is easy to draw the skin or meat around the thread by this return, and wrinkles and the like can be effectively removed.

  Specifically, as shown in FIG. 1, for example, the surgical thread 8 is preferably provided with a barb 10 on the peripheral surface of the thread body 8a. If the thread main body 8a is provided with such a barb 10, the action of the barb 10 pulls the surgical thread 8 in the direction of arrow C with the knot 15 attached to the left end of the thread main body 8a. By the action of the barb 10, the living tissue 12 can be pulled together with the treatment thread 8 in the direction of arrow C.

  In addition, the specific shape may be applied to the forming operation thread body in reverse order, which has a large resistance in the pulling direction and a small resistance in the pulling direction, and a small resistance in the pulling direction and a large resistance in the pulling direction. The shape formed by turning the eyes back in both directions with the boundary line as the boundary may be used.

  Specifically, for example, as shown in FIG. 2, the barb 10 is not limited to one direction (assuming the barb 10 in FIG. Both the turn 10 of the eye and the turn 16 of the reverse eye may be provided.

  That is, in the treatment thread 14 shown in FIG. 2, the forward turn 10 and the reverse turn 16 are formed on the thread body 14 a with the boundary point P interposed therebetween. The turn 10 has a large resistance in the pulling direction (arrow C direction) and a small resistance in the pulling back (arrow D) direction. On the other hand, the reverse turn 16 has a low resistance in the pulling direction (C direction) and a high resistance in the pulling direction (D direction).

  In the case of the treatment thread 14 in which the barbs 10 and 16 having different directions are formed in this way, the length of the entire thread is set in advance. That is, the length of the yarn is set in advance before cutting, such as 40 cm, 50 cm, 70 cm, and the like.

  When the shape is as shown in FIG. 4, by positioning the boundary at the center of the treatment thread, the resistance increases with respect to the direction in which all the barbs formed on the thread pull up the thread. can do. Therefore, for example, when a treatment thread is inserted into a U-shape or V-shape at a treatment site, if a boundary point P is arranged at the center of the U-shape or V-shape, a single thread is placed at the treatment site. The thread can be pulled up in the opposite direction only by inserting it, and there is no possibility of leaving a treatment mark more than necessary at the treatment site.

  The material of the treatment thread of the present invention is not particularly limited as long as it is a stretchable material. If a stretchable material is used, the pulling that tends to occur at the treatment site even after the treatment can be reduced. In addition, since the treatment site can be given semi-permanent natural elasticity and flexibility, it maintains a semi-permanent state that does not cause a sense of incongruity due to the formation procedure even if it directly touches the site after the treatment. can do. Furthermore, it is possible to flexibly cope with movement around the treatment site.

  The stretchable material is not particularly limited as long as it is suitably used as a medical material. Medical materials include, for example, surgical sutures, artificial blood vessels, fracture joint materials, dental materials, wound dressing materials, artificial skin, contact lenses, intraocular lenses, artificial ligaments, artificial valves, artificial joint sliding members , Mesh, non-woven fabric for medical use, stent, clip, stapler, artificial dura mater, scaffold for tissue regeneration, anti-healing material, disposable syringe, catheter, infusion solution, blood bag, tube, surgical glove, gown, bed sheet, filter, etc. The material used for is mentioned.

  Specifically, the stretchable material is more preferably at least one selected from the group consisting of silicone, natural rubber, synthetic rubber, formalized polyvinyl alcohol, polypropylene, polyurethane, and polytetrafluoroethylene. These may be used alone or in combination of two or more. Among these, silicone, formalized polyvinyl alcohol, polypropylene, polyurethane, and polytetrafluoroethylene have elasticity and flexibility that more closely approximates normal skin compared to conventional synthetic fibers such as polyester and nylon. Therefore, it is particularly suitable.

In addition, formalized polyvinyl alcohol means what formalized polyvinyl alcohol with formalin.
The content of these stretchable materials is not particularly limited, but is generally 10 to 100% by weight, preferably 30 to 90% by weight, more preferably 50 to 80% by weight, based on 100% by weight of the total amount of the material for treatment. Contained in an amount of.

  Further, these materials and other materials may be blended and used. Other materials include, for example, polyethylene, polyester, polyamide, polycarbonate, polyvinylidene fluoride, polyvinyl chloride, polyacetal, styrene, styrene resin, polyacrylonitrile, ethylene vinyl alcohol copolymer, ethylene vinyl acetate. Examples thereof include a copolymer, polymethyl methacrylate, polysulfone, and a blend thereof.

  In addition, as long as it does not impair the effects of the present invention, conventionally known heat stabilizers, antioxidants, UV inhibitors, light stabilizers, colorants, antistatic agents, lubricants, nucleating agents, flame retardants, A filler or the like may be blended.

It is desirable that the surgical thread of the present invention is further used by applying or infiltrating amino acids and / or cytokines.
The amino acid is preferably at least one selected from the group consisting of valine, leucine, isoleucine, alanine, arginine, glutamine, glutamic acid, aspartic acid, proline, cysteine, glycine, serine and lysine. Or two or more types may be used in combination. By applying or penetrating these amino acids into the surgical thread of the present invention, it is possible to reduce the aging of the treatment site and to impart a cosmetic effect. In addition, the affinity and adhesion of the treatment thread in the human body can be improved.

  Specifically, for example, valine, leucine, and isoleucine promote metabolism and function as a kinetic energy source, and also have an effect of increasing muscle strength. Glutamic acid has a moisturizing action and has an effect of giving moisture to the skin. Proline is a major component of collagen that constitutes the skin, and can give the skin firmness. Cysteine has the effect of suppressing the production of melanin contained in the skin.

Cytokines are proteins produced by cells that act on cells that have receptors for them to cause cell proliferation, differentiation, or functional expression.
Specific examples of cytokines include cell growth factors such as interleukins, refokines, chemokines, interferons, FGF or EGF, hematopoietic factors, cell growth factors, cytotoxic factors, adipokines, or neurotrophic factors. . These may be used alone or in combination of two or more. By applying or penetrating these cytokines to the surgical thread of the present invention, cell proliferation, differentiation or functional expression at the treatment site can be brought about, and aging can be reduced and a cosmetic effect can be imparted.

  These amino acids and cytokines may be used alone or in combination of amino acids and cytokines. These may be applied directly to the treatment thread of the present invention during the treatment, or may be used after sufficiently penetrating into the treatment thread of the present invention before the treatment. Thereby, in the skin inner layer, a specific amino acid can be absorbed through a part in contact with the treatment thread, and it is possible to provide not only removal of wrinkles and the like at a predetermined part but also a cosmetic effect and the like. .

The treatment yarn of the present invention is not limited to knitting yarns, monofilaments, etc., and the production method is not particularly limited, and therefore can be produced by using a known method such as a simple melt spinning machine.

<Formation treatment method>
The forming treatment method of the present invention is preferably applied to a treatment for removing sagging skin or wrinkles at a predetermined site in a human body. Examples of these shaping procedures include facial sagging and wrinkling, facial wrinkling, cheek sagging, forehead wrinkling, neck wrinkling, nose wrinkling, etc. Treatment: bust formation treatment such as sagging breasts and breast augmentation; body shaping treatments such as sagging buttocks.

  The surgical thread of the present invention is preferably used in combination with a specific forming surgical needle (hereinafter also referred to as “the surgical needle”). Specifically, the specific surgical needle is a surgical needle having a shape as shown in FIG. 3, for example. The surgical needle 2 is manufactured, for example, as a needle having an overall length of about 140 mm and a diameter of about 1 mm to 2 mm. Therefore, for the convenience of explanation, the scale ratios in the radial direction and the length direction are different. ing.

  As shown in FIG. 4 in an enlarged manner, the inside of the needle body 2a is a hollow portion 4, and this hollow portion 4 is a thread passage. Further, both end portions of the needle body 2a are cut obliquely to form piercing portions A and B. One of these piercing portions A and B is closed, and the other piercing portion B is open to the outside.

Further, a hole 6 is formed in the side wall close to the blocked piercing part A, and the hole 6 opens into the hollow part 4.
The needle body 2a may be made of, for example, titanium or a titanium alloy, and may be coated with a fluororesin having a low frictional resistance so that the needle can be easily inserted.

  Moreover, although the hole 6 is preferably a long hole, it may be other than the long hole and is not particularly limited. Furthermore, the number of the holes 6 is not limited to one, and two or more holes 6 may be formed at a predetermined interval. The hole 6 may be formed so as to penetrate both sides of the needle body 2a.

When performing treatment using the treatment thread 14 shown in FIG. 2 in which the barbs 10 and 16 in both directions are formed and the treatment needle 2 shown in FIG. 3, the treatment is used as follows, for example.
That is, as shown in FIG. 5, the treatment thread 14 in which the barbs 10 and 16 in both directions are formed is set in the hollow portion 4 of the treatment needle 2. The treatment thread 14 is inserted from the hole 6 through the hollow portion 4 toward the piercing portion B having an open end.

  In use, as shown in FIG. 5, the state in which the end portion of the treatment thread 14 is not exposed from the piercing portion B is set as an initial state. From this initial state, as shown in FIG. 6, the surgical needle 2 is pierced into the corresponding portion of the biological tissue 12 and advanced in the direction of arrow E. After the piercing portion B of the surgical needle 2 is exposed from the living tissue 12 as shown in FIG. 7, the surgical needle 2 is further advanced in the direction of arrow E. Thereafter, as shown in FIG. 8, when most of the surgical needle 2 protrudes from the biological tissue 12 and the hole 6 of the surgical needle 2 is not exposed from the biological tissue 12, it proceeds in the direction of arrow E. As shown in Fig. 2, the surgical needle 2 is tilted in a predetermined direction. Then, the surgical needle 2 is advanced in the arrow F direction, that is, in the returning direction. Then, as shown in FIG. 10 together with the surgical needle 2, the surgical treatment thread 14 advances in the arrow F direction while leaving the boundary point P in the living tissue 12. When the progression in this direction further continues and the piercing portion A passes through the living tissue 12, the surgical needle 2 is pulled out from the living tissue 12, as shown in FIG. At this time, it is preferable to pull out the surgical thread 14 while grasping the return 16 side.

As a result, the surgical needle 2 is pulled out from the biological tissue 12 and only the surgical thread 14 remains in the biological tissue 12.
Then, if both ends of the treatment thread 14 exposed from the biological tissue 12 are pulled in the direction of the arrow F and knots are provided on each side, the biological tissue 12 is moved in the direction of the arrow F by the action of the barbs 16 and 10. Can be pulled. Alternatively, both ends of the treatment thread 14 may be combined into one.

  By such a treatment method, for example, it becomes possible to pull up the slack of the hanging cheeks or stretch wrinkles around the eyes. In addition, since there are two portions where the needle passes through the biological tissue 12, that is, one location when traveling in the direction of arrow E and 1 location when traveling in the direction of arrow F, there is little possibility that the needle passage portion remains as a scar. Become. Therefore, it is extremely effective in the field of cosmetic surgery.

  By adopting such a treatment method, for example, when raising the slack of the cheek, as shown in FIG. 12, for example, the needle 2 is pierced at the position of the arrow X, and the needle 2 is returned in the Y direction. Thus, the thread 14 is arranged in a substantially U shape. Then, both ends are tied together. At this time, there are two places where the needle 2 passes through the living tissue as described above.

  By leaving the treatment thread 14 in this manner, the sagging of the cheek can be effectively pulled up by the action of the barbs 10 and 16. In addition, treatment marks are not left unnecessarily at the treatment site.

  The position and shape for inserting the surgical needle and inserting the surgical thread into the body are not particularly limited, and may be linear, U-shaped, V-shaped, O-shaped, or zigzag-shaped depending on the purpose. It may be inserted.

  As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all. For example, when the barbs 10 and 16 are provided, the pitch between the barbs 10 or 16 and the size of the barb 16 are not limited.

  In the above embodiment, an example in which one hole 6 is formed in the needle body 2a is shown, but two or more holes may be formed. If a plurality of holes 6 are formed in this way, the thread passing position with respect to the needle body 2a can be selected as necessary.
