Which can benefit from the molding effect is emerging as an alternative.

In recent years, non-surgical procedures called "petit molding" have become popular with the advancement of medical products and molding technologies, which can be easily and safely beautiful, and these non-surgical procedures do not knife the body unlike plastic surgery, Botulinum toxin (Botulinum Toxin)) or filler (filler) injected by injecting or using a medical room was developed to lift the skin, etc., without the incision process is relatively simple to be performed on the desired site There is a characteristic that it is possible to carry out the procedure without any inconvenience in terms of cost, and the safety is high because many people do not put the knife without inserting the implant.

The present invention relates to a technique of lifting using a medical room, and a lifting technique of such a medical room is performed by using a device called a cannula Unlike conventional injection needles, it is possible to minimize various side effects such as reducing pain during surgery or preventing blood vessels from being stuck.

The lifting procedure using this medical room is flexed to enable safer procedures. The medical room used in this case is a special medical suture (PDO (polydioxanone), which is harmless to human body, The PDO suture is used to suture the surgical site, and lifting treatment is performed in which the sutured skin is pulled by the surgical equipment such as the cannula and the tool, A variety of techniques for yarns have been developed.

As an example of the prior art, the suture for lifting, which is disclosed in Japanese Patent Application Laid-Open No. 10-2018-0006012, and a method of manufacturing the suture are disclosed. In manufacturing a suture made of a biodegradable and / or character material, A step of injecting the material of the anchor portion into two injection apparatuses, a step of integrally forming an anchor portion projecting on the outer peripheral surface of the fiber yarn by a single molding with the fiber yarn, and the anchor portion of the fixed portion and the variable portion, The suture thread and the anchor portion are integrally formed by double or multi-injection molding so that the tensile strength can be improved and the shape of the anchor can be formed in various shapes .

Another example of the prior art is disclosed in Korean Patent No. 10-1628991. In the structure of the conventional art, a tubular main body portion having a tip end closed by forming an injection hole into which fluid is injected in an inner longitudinal direction, And a fluid inflow space communicated with the inflow hole of the main body and inflated when the fluid flows through the inflow hole, the inflow space having a fluid inflow space formed inside the inflow hole, .

However, such a conventional technique has a problem in that since the suture is manufactured by the double or multi-injection with the fiber of the suture, the process is complicated and the production time and the productivity are greatly reduced.

In addition, since the engaging portion for hanging on the skin always has a shape protruding outward from the main body portion, it is not easy to insert into the cannula, and the cannula having an inner diameter larger than the outer surface of the main body portion is used. There is a problem that side effects are caused depending on the skin condition of the patient.

The suture for lifting surgery according to the present invention includes a suture 100 formed in a cylindrical shape having a predetermined diameter and a suture 100 formed adjacent to the outer surface of the suture 100 radially and inserted into a wrinkled skin, The hooking protrusion 200 is formed on the outer surface 101 of the suture 100 so as to be easily inserted into the needle C having a tubular shape, And a plurality of the locking protrusions 200 formed adjacent to the suture 100 radially in the longitudinal direction are formed so as not to face each other, and the locking protrusion 200 is formed so as not to protrude from the inside of the skin The locking protrusion 200 is protruded outward from the suture 100 by pulling the operator so as to maximize the fixing force with the skin.

A piercing 110 is provided on the inner side of the pawl 200 and is provided between the pawl 110 and the pawl 200 so that the pawl 110 is close to the pawl 200, And an engaging protrusion 120 provided between the engaging protrusion 200 and the engaging protrusion 200 to facilitate gripping of the suture thread 100. [ And a display unit 130 provided on the surface of the joint part 130 for allowing a practitioner to grasp the skin insertion length of the suture 100, (140).

The suture 100 is formed in a cylindrical shape having a predetermined length as a whole. The suture material 100 may be made of a material such as polydioxanone or a biodegradable chitin ingredient modified with celluloses that is biodegraded after a lapse of a predetermined time use.

For example, the suture 100 may be formed with a perforation 110 so as to have a predetermined gap in the longitudinal direction thereof to form the latching protrusion 200 so that the latching protrusion 200 can be formed, So that it can be inserted into the corrugated skin through a tubular surgical needle (C), that is, a cannula, which guides the inserted needle to be inserted.

At this time, the perforation 110 is formed by inserting or supporting a part (in particular, a locking projection end) in the skin after the locking protrusion 200 formed is inserted into the skin, It is preferable that an extended punch 120 is further formed in the punch 110 in the vicinity of the punch 200 so that the punch 110 can be held tight.

Accordingly, through the formation of the extended perforation 120, the end of the locking protrusion 200 has a pointed shape with a sharp length, and the suture 100 is easily inserted into the skin through the needle, The pulled skin is pulled tightly by the pull of the operator.

At this time, it is preferable that the latching protrusion 200 has a resiliency such that a part of the end of the latching protrusion 200 can be inserted into or supported by the inner skin by pulling the operator, .

In addition, as shown in the drawing, the suture 100 is formed with a joint portion 130 in which a locking protrusion 200 is not formed at a center portion thereof with respect to a predetermined length from the front end to the rear end, And the operator can visually confirm how long the suture 100 is inserted into the corrugated skin.

In order to maximize the effect of the joint 130, the length D1 of the joint 130 is formed in the suture 100 to have a length of 2.5 to 3.5 mm, A plurality of display units 140 may be formed in accordance with the length of the suture thread 100. When the plurality of suture units are formed, a display unit 140 may be formed on the surface of the joint unit 130, It is preferable to make it possible to more easily grasp the lengths of the first and second optical fibers 100 and 100.

In addition, a plurality of the locking protrusions 200 are formed on the outer surface of the object 100, and are directly contacted with and fixed to the skin of the patient so that the wrinkled skin can be easily pulled.

For example, the locking protrusions 200 are formed through the perforation 110 and the extension perforation 120 so that the suture 100 is radially and longitudinally symmetric with respect to the perimeter 130, .

In this case, the plurality of locking projections 200 formed on the suture 100 are formed so as not to protrude from the outer surface of the suture 100, and are formed to have the same spacing in the cylindrical suture 100, It is preferable that the interval D2 is formed within a range of 4.0 to 4.5 mm (a distance between the ends of the pair of locking projections) so that when the pull is generated by the practitioner, the end can be inserted or supported inside the skin.

If the distance D2 is less than the predetermined distance D2, the interlocking between the engaging projections 200 may increase the area for stimulating the skin, resulting in side effects after the procedure. In this case, The number of the locking protrusions 200 to be inserted or supported is small, so that when the operator pulls the suture 100 out of the skin, the suture 100 may be detached, and the numerical value is limited to satisfy this.

In addition, by preventing the end of the latching protrusion 200 from protruding outwardly from the object 100 so that the latching protrusion 200 can easily be inserted into the needle, the inner diameter of the needle is small (the inner diameter of the cannula is equal to the outer diameter of the object) The operator can select the stimulation that is applied to the skin as much as possible when the needle is inserted into the skin.

In addition, the ends of the respective locking projections 200 are formed to have a thickness capable of being bent by elastic force so as to be easily inserted into or supported on the skin. For this purpose, the thickness T is formed within 0.03 to 0.05 mm.

Further, the latching unit 200 is divided into a first region Z1 and a second region Z2 such that a plurality of latching protrusions 200 are formed in the longitudinal direction of the object 100 with the joint portion 130 as a center, The first zone Z1 or the second zone Z2 of the first zone Z1 or the second zone Z2 may be symmetrical to each other but not opposed to each other so that the end of each of the engaging projections 200 may lead to a zigzag shape by an imaginary line L .

In addition, the first area and the second area may be formed on the object 100 with the same length, but may be formed on the object 100 so as to have different lengths as required, and the operator may easily change direction And to take actions such as use.

The suture 100 according to the present invention having the above-described structure does not protrude from the outer surface of the suture 100 so that the outer diameter of the suture 100 (in a state where the protrusion does not protrude outside the suture) It is possible to perform the operation with less irritation to the skin of the patient as much as possible.
