The most frequent procedure for wrinkle removal is face lift, and various procedures have been performed. Among these, the method that has been practiced since the earliest time, pulling the skin up to cut the extra skin, and sewing the skin can be done to support the facial lift, but this surgery is more dangerous than the rapid effect of the surgery itself, Scars can be left in the forehead and forehead lines, and the recovery period is also about six weeks.

In recent years, in order to compensate for the disadvantages of such procedures, a medical suture innocuous to the human body is inserted into the skin to stimulate skin contraction and regeneration by applying skin tissue stimulation, A lifting technique for lifting and fixing the stretched skin tissue has been proposed. This lifting technique is easier to perform than conventional surgical procedures, and has a lot of spotlight because it does not interfere with daily life.

In recent years, a lifting thread technique has been preferred in which a suture thread (a so-called projection thread) having a plurality of projections formed on its outer surface is used. Such a projection thread is formed by additionally forming projections having a certain direction on the surface, It is possible to apply more mechanical stimulation to the skin tissue and to improve the effect of the procedure by increasing the fixing force of the suture to the skin tissue.

However, the conventional protruding thread has a problem that the thickness of the thread becomes thick due to the protrusion, and the tip of the sharp protrusion stimulates the nerve tissue, resulting in a lot of pain during the procedure. In addition, the elasticity of the seal yarn in the structure is limited, thereby restricting natural movement of the face, giving a foreign body feeling, and bringing about an unnatural facial expression or facial shape.

In order to compensate for the disadvantages of such conventional projection chambers, projection chambers having various shapes and shapes have been proposed. However, as the shape / shape of the projection chamber becomes more complicated as compared with the conventional one, the construction of the process / apparatus for manufacturing the same becomes complicated and the time / cost ratio changes economically. For example, conventionally, a cutting knife has been used to cut a part of one side or both sides of a projection chamber to make a cutting groove. However, in the present projection room, a cutting groove or shape In many cases. In addition, such a cutting method is required to precisely align and control the protruding chambers and the cutting knife for transfer, in addition to the maintenance / repair problem of the cutting knife.

The practical difficulty in such a manufacturing process is a great difficulty in manufacturing a projection chamber having a complicated shape.

Referring to FIGS. 1 and 2, the medical suture 100 may include a plurality of depressions 110.

The plurality of depressions 110 are formed on one side of the medical suture 100 and on the other side thereof corresponding to the longitudinal direction of the medical suture 100 as a structure for improving the mechanical stimulation and / Respectively. In one embodiment, the depressions 110 may be formed alternately in a zigzag fashion on one side and the other side of the medical suture 100, as shown in FIG. When the depression 110 is alternately formed on both sides of the medical suture 100, the medical suture 100 itself is strengthened and the restoring force of the medical suture 100 itself is strengthened so that the medical suture 100 inserted into the skin contracts And naturally relaxed and restored according to the relaxation, thereby preventing the facial movement from being unnaturally limited, and minimizing the adverse effects due to the procedure such as skin damage, asymmetry, and the like. According to an embodiment to which the present invention is applied, the depressions 110 may be formed so as to correspond to each other at the same position of one side surface and the other side surface of the medical suture 100.

Each of the plurality of depressions 110 may include a flat surface 120 and an inclined surface 130.

The flat surface 120 may be formed by cutting one side and / or the other side of the medical suture 100 in parallel with the longitudinal direction. In addition, the flat surface 120 may be formed to have a surface area of more than a predetermined value. By increasing the area of contact with the skin tissue inserted into the indentation 110 or made in the depression 110 during the procedure and / or after the procedure through the flat surface 120, The adhesion with the suture 100 can be improved and the skin regeneration effect can be maximized.

The feeder 310 feeds the raw suture material to the device 400 by mounting a spool on which the raw suture material is wound. The raw material suture material is fed from the feeder 310 to the deformation part 320 through the feeder 360, And the stationary part 330 and the like. At this time, the raw material suture is a yarn having a circular cross section with a predetermined thickness, and may preferably be composed of a bioabsorbable medical polymer. For example, the raw suture may be made of polylactic acid, polydioxanone, poly-glycolic acid, polycaprolactone, lactic acid, glycolic acid, Glycolic Acid), and the like. However, according to an embodiment to which the present invention is applied, the raw material suture may be constructed by applying a bioabsorbable medical polymer such as polypropylene, nylon, or a mixture thereof.

The deforming portion 320 can deform the shape of the raw suture by heating the raw suture supplied from the supplying portion 310 to a predetermined temperature and pressing the raw suture in a horizontal direction. To this end, the deforming portion 320 may include a heating plate composed of a lower plate and an upper plate arranged symmetrically up and down. By placing the raw suture between the lower plate and the upper plate and heating and pressing the raw suture through the heated lower plate and / or the upper plate, the deformed portion 320 can be deformed such that the width of the raw suture is smaller than the length So that it is deformed into a shape as large as the ratio.

In one embodiment, at least one fixing groove may be formed on the upper surface of the mounting portion 330, and both ends of the raw suture fastened to the mounting portion 330 may be configured to exert a predetermined tensile force. This makes it possible to prevent the raw material suture from being detached from the designated position when the incision or the like is performed on the raw suture.

The masking portion 340 may include a mask in which at least one incision pattern is formed. By using such a mask, the masking portion 340 can deform the laser emitted from the processing portion 350 into a predetermined shape. That is, for example, the masking portion 340 can move the mask up and down and / or left and right so that each of the incision patterns formed on the mask can be aligned to correspond to the raw sewing thread stuck to the mounting portion 330. Accordingly, the laser beam emitted from the machining unit 350 to the mask is deformed into a shape corresponding to at least a part of the incision pattern, irradiated to the raw sewing thread stuck to the mounting unit 330, and at least a part of the raw sewing yarn is irradiated to the incision pattern And can be cut into corresponding shapes. In one embodiment, the incision pattern may be formed to be suitable for forming a plurality of depressions 110 on both sides of the medical suture 100 described above with reference to Figs.

The processing unit 350 may include a laser emitting unit for emitting a laser to the outside and a moving head for controlling the position of the laser emitting unit. The moving head moves the laser emitting unit horizontally and / or vertically to emit a laser of a predetermined intensity along each of the incision patterns of the mask, so that at least a part of each of the raw sewing sutures is cut into a shape corresponding to the incision pattern. At this time, the intensity of the laser beam can be adjusted so as to be suitable for cutting only the raw suture without deforming or damaging the external shape of the mask and the incision pattern, and it is possible to irradiate the mask in the form of a line beam or a spot beam . Herein, the line beam refers to a laser having a shape whose length is considerably larger than the width, and the spot beam can refer to a laser having a spot shape.

The transfer unit 360 may sequentially transfer the raw suture material from the supply unit 310 to other components such as the deforming unit 320 and the mounting unit 330. The transfer unit 360 may include at least one transfer roller electrically driven and a control module for controlling the driving of the transfer roller. However, the configuration of the transfer unit 360 is an example, and the transfer unit 360 can be implemented using various driving means, etc. according to the embodiment to which the present invention is applied.

Although not shown in FIG. 3, the manufacturing apparatus 400 may further include a sensing unit (not shown). The sensing unit senses the position of the cutting pattern of the raw suture and / or mask mounted on the mounting part 330 and may transmit the sensing signal to the masking part 340 and / or the processing part 350. Accordingly, the masking portion 340 aligns the mask corresponding to the position of the raw sewing thread, or the cutting portion 350 moves along the cutting pattern to move the laser emitting portion to perform the cutting. The sensing unit may be implemented through a camera module, but is not limited thereto.

In addition, the plurality of openings 512 formed by punching the surface of the mask 500 are arranged in a predetermined manner, so that the cutting pattern 510 can be formed.

For example, as shown in FIG. 5, the incision pattern 510 may be formed by cutting an opening 512 having a shape corresponding to the depression 110 described above with reference to FIGS. 1 and 2, And alternately arranged on both sides. When laser cutting is performed using the cutting pattern 510, a plurality of depressed portions 110 are formed on the one side and the other side corresponding to the one side of the raw suture. According to an embodiment, the incision pattern 510 may be formed by arranging the openings 512 corresponding to the shape of the depressions 110 to be mutually symmetrical from the center to both sides have. In this case, a plurality of depressed portions 110 are formed in the raw suture material so as to be symmetrical with respect to one side surface and the other side surface corresponding thereto.
