The present invention relates to a suture, wherein a synthetic resin is thermocompression-bonded by a press to produce a suture having a circular cross section, wherein the suture comprises a yarn-shaped body and a plurality of locking protrusions formed on the outer circumference of the body.

Polydioxanone is used as a synthetic resin thermocompression-bonded by the press.

The thermocompression temperature of the press is 50 to 60 deg. C, and the optimum temperature is 53 deg.

In addition, the locking protrusions formed on the outer circumference of the suture thread are formed radially in the up, down, left, and right directions, and the locking protrusions are formed in the shape of an arrowhead with a total of four protrusions spaced by 90 degrees apart.

In addition, the latching protrusions formed on the outer periphery of the suture thread may be spaced apart by 120 degrees to form a total of three.

The latching protrusions formed in the shape of an arrowhead on the body are spaced apart from each other along the body length direction of the suture.

A plurality of locking protrusions formed in the shape of an arrowhead on the body are spaced apart from each other by a predetermined distance in the forward and backward directions with respect to the center of the body.

The protrusions 2 of the arrowhead shape are formed on the front and rear sides with respect to the center of the body 1, and are formed symmetrically with respect to each other.

In addition, an arrowhead-shaped locking protrusion formed on the front side of the center of the body is formed in a greater amount than an arrowhead-shaped locking protrusion formed on the rear side.

That is, 27 to 35 locking protrusions are formed on the front side of the center of the body, and 36 to 45 locking protrusions are formed on the rear side of the center of the body.

It is preferable that the number of the arrowheads formed on the front and rear sides of the center of the body is 32 forward and 40 rearward.

The locking protrusion includes a first vertical portion which is formed at the front of the center of the body and a first inclined portion which is inclined lower toward the rear at the upper end of the first vertical portion.

"It is a form.

Meanwhile, as another embodiment of the present invention, a guide projection 5 is coupled to an upper portion of the arc portion.

The circular arc portion is formed with a circular groove, and the guide protrusion is composed of a plate-like body 5-1 and a protrusion 5-2 protruding downward from the lower surface of the body, Is inserted into the groove of the arcuate portion and is tightly coupled.

The protrusion of the guide protrusion is rotatable in a state of being inserted into the groove of the arc portion.

When the suture is used to suture the skin, the suture portion is not released due to the locking protrusion formed on the outer circumference of the suture. However, the guide protrusion coupled to the arc portion of the suture is rotated to intersect with the locking protrusion formed on the outer circumference of the suture So that the suture area is more firmly sutured.

In addition, a support groove 5-3 is formed on one side surface of the plate-like body.

Therefore, when the skin is sewn and sewn using the suture, the skin is partially inserted into the support groove, and the suture part is more firmly sutured by the suture.

The suture is inserted into a surgical needle, and then the skin is stitched to be sewn. In the outer periphery of the suture, a locking protrusion is formed to form a knot of the suture.

In addition, the suture inserted into the skin will be biodegraded and disappear after 25 to 35 days, and the optimal time for the suture to be cut off is 30 days.

And biodegradable sutures use tolerance techniques. The well-known technique of this tolerance is described in the prior art of biodegradable surgical sutures of Patent Registration No. 0126599, biodegradable chitin sutures modified with cellulose of Patent Publication No. 1996-0014022, fibers and chitin resins As described above, since the suture sewn on the suture site is biodegraded and then eliminated, detailed description thereof will be omitted.

Therefore, according to the present invention, a locking protrusion is formed on the outer circumference of the suture, and when the protrusion is inserted into the skin, the locking protrusion fixes the tissue in the opposite direction to insert the skin so that the skin can be pulled and fixed without sagging or sagging. There is a remarkable effect that it is possible to seal even a three-dimensional region, to eliminate the phenomenon of scarring after the recovery because the knot of the suture is not formed during the procedure, to minimize the pain and swelling of the operation site, and to shorten the procedure time.
