Description

[0001] The present invention relates to an apparatus for manufacturing surgical thread,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for manufacturing a cosmetic surgery thread, and more particularly, to a cosmetic surgery thread capable of forming various patterns of barbs and an apparatus for manufacturing the same.

Generally, face lift techniques result in extensive incisions in the facial tissue and several layers of the skin, after which these tissues are re-stitched and rearranged up and back. This conventional facial lift technique inevitably leaves a large scar, and involves dangers such as skin necrosis, nerve damage, vascular damage, hair loss, ear potentials and unnatural placement of the face.

The greatest drawback of these surgical techniques is the significant boils and bruises that occur with the rest period during the post-operative recovery period, and patients are not able to socialize during this recovery period.

A variety of techniques have been developed over a long period of time to minimize scarring and tissue incisions caused by facial lift procedures.

One widely used technique is to use a suture formed with a barb, where the barbs are oriented in a direction opposite to the tension of the thread. The suture is inserted with a gentle curve into the lower part of the soft tissue, thereby not only causing the soft tissue to rise, but also forming a gentle lift, which is preferable for the cheekbones and cheeks. This technique eliminates the need for incision or lift of facial tissue, eliminating scarring and complications, but it can also be used to remove heavy, light facial tissue such as forehead and eyebrows, mid-face, neck jowl, It is not effective. The heavier tissue of the abovementioned sites will pull the barbs of the surgical thread considerably before they sag or fall prematurely.

Korean Patent Registration No. 20-0344226 (Feb. 27, 2004) discloses a medical suture. The disclosed medical suture is to fix the wrinkles of the face and the sagging or elongated skin without pulling the incision, and it is not necessary to form the knot of the suture even if the incised skin is not only flat but also three-dimensional area. And the left and right protrusions are continuously and repeatedly formed while keeping the inclination of about 25-40 중앙 in the center direction.

In Korean Patent Registration No. 1185583 (September 18, 2012), there is disclosed a technical structure of a suture that includes no suturing operation and a kit including the suture, and Patent Publication No. 2005-0108494 (Nov. 17, 2005) Korean Patent Registration No. 1057376 (Aug. 10, 2011) discloses an absorbable suture having a protruding external structure on a surface and a manufacturing method thereof.

A method of manufacturing a suture includes preparing a suture body having a protrusion formed on a surface thereof by injection molding a bioabsorbable polymer, And a post-treatment step of subjecting the stretched suture to a gas heat treatment.

Since the conventional suture thread is formed by injection molding or simply cut in the direction as described above, the barbs are not uniformly formed in directions, and the barb spacing from the body of the thread is not uniform. In particular, it is impossible to precisely form a barb.

The first gear 104b provided on the elevating roller 104b is formed to have a length longer than the pitch due to the ascending and descending of the elevating roller 104b so as not to deviate from the state of engagement with the second gear 106b when the elevating roller 104b ascends or descends I have.

The operation of the surgical thread manufacturing apparatus according to the present invention constructed as described above will be described below.

In order to manufacture the surgical thread according to the present invention, as shown in FIG. 1, the original string 200 supplied from the supply reel 81 is divided into a second support roller 94, a weight roller 96, The support rollers 93 and the upper rollers 104 of the primary row rotating unit 100 and the pressing rollers 106 and between the upper surface of the table 50 and the grippers 61a of the primary row clamper 61, Is wound on the reel (82). At this time, idle rollers installed between the table and the take-up reel 82 can be passed through.

The barb forming unit 40 is conveyed by the first conveying unit 20 and the first driving shaft 42 is moved by the second driving motor 43 in the state that the barb 200 of the operation room is installed, And the barb 210 pressed by the grip portion 61a of the wire rod clamp 61 is cut in the oblique direction on the upper surface of the table 50 to rotate.

As described above, the forward and backward movement of the barb-forming unit 40 by the first and second feeding units 20 and 30 is performed by the rotation of the first driving motor 23 of the first feeding unit 20 1 lead screw 24 is rotated and the first transfer member 25 connected thereto is moved so that the first base member 12 is advanced and the second base member 12 mounted on the upper portion of the first base member 12 The barb-forming unit 40 provided on the member 13 advances.

The follower roller 31 of the second conveyance unit 30 or the follower roller 31 provided on the rear end side of the housing 41 of the barb-forming unit 40 in the process of advancing as described above, (Forward direction) of the barb-forming unit 40 while following the barb 32 in the forward direction. That is, the second base member 13, on which the barb-forming unit 40 is installed, is transported in a direction perpendicular to the transport direction of the first base member 12. Therefore, the cutter 45 of the barb-forming unit 40 is moved in the oblique direction with respect to the advancing direction of the original string 200 to form the barb 210 on the original string.

When the formation of the barb is completed, the first driving motor 23 of the first conveying unit 20 is rotated in the opposite direction, so that the first base member is retracted. The main wire clamp 61 is rotated by the pivoting member 65a of the clamping pivot portion 65 to lift the gripper portion 61a against the table 50 to remove the gripping force of the main wire 200. [ That is, when the pivotal member 65a provided on the housing or the first base member 12 is retracted, the lever unit 61b is pulled to rotate the original line clamp 61 so that the holding unit 61a is moved to the table 50, .

When the gripping force of the webbing 200 is removed from the table 50 as described above, the winding reel 82 is rotated to move the webbing 200 by one pitch and the lifting and lowering driving unit 110 The lifting member 103 is lifted or lowered to the timing belt 114 and the connecting member 115 to rotate the second pulley 113 by rotating the second pulley 113, 200 are rotated. The rotation of the circular line 200 is positioned on the table 50 so that the barb 210 can be formed at a position different from the position where the barb is formed.

When the rotation of the circular line 200 is performed as described above, the barb is formed on the circular line 200 as described above. That is, when the barb-forming unit 40 advances, the pivotal member 65a formed on the first base member 12 or the housing 41 is advanced to thereby rotate the web bar clamp 61, And is closely attached to the table 50 side to grip the original line.

When the wire is gripped as described above, the barb forming unit 40 advances to cut the wire 200, thereby forming the barb 210.

Here, in order to form a barb having a predetermined pitch in one direction on the original line, it is not necessary to drive the original line rotating unit 100. [

As described above, the apparatus for manufacturing a surgical thread according to the present invention can form barbs by cutting the outer circumferential surface of a raw wire in an oblique direction. Further, by moving the cutter in the oblique direction, the uniformity of the barb formed can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

It can be widely applied to an apparatus room for manufacturing a surgical thread of the present invention or an apparatus for producing a special rope of the present invention.
