Description

Suture barb forming device {Barb Forming Apparatus Of Medical Thread}

The present invention relates to a suture barb forming apparatus for forming a barb in a suture which is a medical surgical thread, and more particularly, to a suture barb forming apparatus capable of forming a barb having an improved locking effect on a suture surface.

In general, the face lift technique involves extensive incisions in facial tissue and various layers of the skin, which are then resealed and rearranged upwards and backwards. Such conventional face lift techniques inevitably leave large scars and carry risks such as skin necrosis, nerve damage, blood vessel damage, hair loss, ear dislocations and unnatural placement of the face.

Various techniques have been developed over a long period of time to minimize scarring and tissue dissection caused by the facial lift process. One well known technique is to use barbed sutures. The barbs protrude obliquely in a direction opposite to the direction in which the suture tension acts. The suture with barbs allows passage in one direction by the barb, but becomes difficult to pass in the opposite direction. The barbed suture is generally elongate shaped, having a pointed leading end and a plurality of axial and circumferentially spaced barbs on the outer surface of the elongated shaped. The suture is inserted into the lower part of the soft tissue with a gentle curve, thereby not only softening the soft tissue but also forming a gentle lift.

Sutures are made using stretchable bioabsorbable polymers. Bioabsorbable polymers are bioabsorbable polymers used for medical purposes and include l-lactide (L-lactide) polymers (eg PLA (L-lactide)), glycolic acid (Glycolide) polymers (eg PGA (Polyglycolide) or lactic acid). Copolymers of glycolic acid (Glycolide) (eg, PolyL-lactide-co-glycolide (PLGA), Poly L-lactide-co-DLlactide (PLDLA)), polydioxanone, etc. may be used.

Korean Patent Registration No. 20-0344226 discloses a medical suture. The published medical suture pulls and tightens wrinkles and sagging or sagging skin of the face without incision, and the cut skin does not need to form a suture knot even in flat as well as in three-dimensional areas. The three protrusions are formed at an angle of 120 degrees to face each other, while maintaining the inclination of about 25-40 degrees in the central direction, and have a technical configuration of continuously forming left and right protrusions repeatedly.

Conventional suture having a barb is not enough protrusion height of the barb, there is a problem that the defect such as the suture is broken in the barb forming portion of the barb forming process, such that the barb is not formed in a constant form.

Is integrally advanced toward the suture (MT) ("A" direction of Figure 4) while crossing the suture (MT) while cutting into the suture (MT) barb (B) is formed on the surface of the suture (MT).

The barb B is formed by cutting the end of the cutter blade 5151b into the suture MT first and the cutter first driving unit 512 to move forward to form the depth D1 in the suture MT. The barb B includes a first molding part B1 and a second molding part B2.

The first molding part B1 is a part formed on the surface of the suture MT by driving the cutter first driving part 512.

In the first molding part B1, the cutter first driving part 512 is operated, and the second driving part roller 5516 is brought into rolling contact with the guide linear part 5181 so that the cutter second driving body part 5125 is operated. Advancing toward the suture MT, the cutter 5151 is formed by cutting across the suture MT.

The second molding part B3 is driven by the cutter second driving body 5125 to move forward toward the suture MT. The second driving part roller 5603 is in contact with the guide inclination part 5503 and the cutter second driving is performed. The main body 5152 is moved forward along the longitudinal direction of the suture MT on the first drive guide 5125 and the cutter 5151 is also moved together (in the "A" direction in FIG. 6), and thus the front of the cutter 5151. The suture MT portion located at is cut by the cutter 5151 and is formed to rise along the front portion of the cutter 5151. The gap MT2 is formed between the suture MT and the rear side of the cutter 5151 when the second molding part B3 is formed.

After the second molding part B3 is formed, the cutter second driving body 5516 rotates the cutter blade 5181b so that the inclined cutter 5151 is rotated in a direction perpendicular to the suture MT. In rotation () direction in FIG. 6).

When the cutter 5151 is rotated in a direction perpendicular to the suture MT, the barbs B are raised. Since the barb B is raised, the barb B is protruded laterally from the surface of the suture MT and can be supported by a high supporting force when inserted into the skin.

The barb forming part 510 moves in the longitudinal direction by the operation of the first movable part 530 during the operation of the suture barb forming apparatus 500 to form a plurality of barbs B. The barb forming part 510 forms one barb B and then moves in the longitudinal direction by the operation of the first movable part 530 to form another barb B. The barb B is formed in plural along the longitudinal direction of the suture MT.

In the suture barb forming apparatus 500 according to the present invention, power is supplied to the barb forming part 510 and the support member 520 before the cutter 5151 is in contact with the suture MT. The supporting member 520 is heated.

The cutter 5151 may be formed of a metal conductor, and power may be directly supplied to the cutter 5151 so that the cutter 5151 may be heated. The barb forming portion 510 is provided with a heating member (not shown), which is a conductor contacting the cutter body mounting portion 5193, and is supplied with power to the heating member to heat transfer from the heating member to the cutter 5151. It is also possible to allow the cutter 5181 to heat up.

The support member 520 may be formed of a metal conductor, and power may be directly supplied to the support member 520 so that the support member 520 may be heated. The main body 501 is provided with a heating member (not shown) which is a conductor contacting the supporting member 520, and supplies power to the heating member to support the supporting member by heat transfer from the heating member to the supporting member 520. It is also possible to allow 520 to heat up.

The support member 520 is heated to a range of 40 ~ 80 ℃. The suture MT is heated and softened in contact with the support member 520 before the barb B is formed. If the temperature of the support member 520 is less than 40 ℃ softening of the suture (MT) is not made well, if the temperature of the support member 520 exceeds 80 ℃ is excessively softened, rather unsuitable for processing.

The suture barb forming apparatus 500 may be provided inside the oven OV. The suture barb forming apparatus 500 is provided in an oven (OV) to operate in an atmosphere of 40 ~ 80 ℃ range.

Since the cutter 5151 is cut into the suture MT while the cutter 5151 and the support member 520 are heated in the oven OV, the barb B may be damaged without deterioration of the suture MT. Can be formed.

In addition, since the heating of the suture MT is also performed in the oven OV, heat is not transferred between the cutter 5151 and the suture MT, and the suture MT is formed when the barb B is formed using the cutter 5181. The barb B is easily formed without damage such as chipping.

Therefore, when the barb B is formed, in particular, even when the second molded part is formed, defects such as suture MT may be prevented from being prevented, and the second molded part may be smoothly formed.

The suture barb forming apparatus according to the present invention has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope should be defined by the technical spirit of the appended claims.
