Description

Manufacturing method for Medical round needle [

The present invention relates to a fillet injection rod, and more particularly, to a fillet injection rod used in a fillet insertion procedure for skin lifting by inserting a suture into a skin tissue by inserting the fillet into a dermis or a muscle layer.

As a result of increasing interest in the skin, surgical surgical knives such as facial lift, filler insertion, botox injection, and laser skin rejuvenation are used for the purpose of improving the symptoms caused by aging such as atrophy, sagging, Procedures are being developed to easily remove wrinkles without touching the face.

Particularly, insertion of a suture into the skin layer to fill the corrugated area, pulling the sagging muscle, and rearranging the adhered fibrous tissue through the stimulation to induce regeneration promotes collagen regeneration in surrounding tissues while the thread is melted, Even after the collagen is newly synthesized, the effect lasts for a long time.

This stitching procedure requires a staple injection needle to insert the suture into the skin tissue, and inserts the suture into a hollow cylinder-shaped staple injection rod and infiltrates the skin. The suture inserted into the fillet injection rod remains in the skin tissue to maintain the lifting state continuously, and the fillet injection rod is released from the skin tissue.

Korean Patent Laid-Open Publication No. 10-2016-0056683 discloses a needle for a sold-inserting operation in which a hooking groove is formed at an upper side of an inner corner portion where a slope portion of a fillet injection rod and a rope hole meet, There is a problem that the tip that is first inserted into the skin tissue is sharp, which damages muscles, tissues, and blood vessels. When the suture is inserted into the injection needle, the skin tissue is damaged at the sharp tip.

In addition, a needle for a sold-out operation disclosed in Korean Patent Laid-Open Publication No. 10-2014-0071712 has an insertion slot for facilitating the insertion of a suture thread at the bottom of a pointed end, The needle is inserted into the skin tissue and the tip of the sharp needle and the cutting surface of the insertion slot are damaged by damage to the muscle, And cysts are generated by the tissue.

Korean Patent Laid-Open Publication No. 10-2016-0056683 (2016.05.20) Korean Patent Publication No. 10-2014-0071712 (June 14, 2014)

In order to solve the above-mentioned problems, according to the present invention, a pin having a front surface in a thimble shape and a rear surface inclined portion is coupled to a base having an opening portion so that a suture is inserted into a staple injection rod quickly, And it is an object of the present invention to provide a manufacturing method of a feed line injection rod that reduces the degree of damage.

There is provided a method for manufacturing a fillet injection rod, comprising the steps of: forming a circular pipe-shaped base having a front sloped portion and a rear sloped portion facing each other at a predetermined angle, A second step of horizontally aligning the pins so that the tips are aligned in the same direction so that the tips are in the same direction, A third step of rotational alignment such that the inclined surface faces upward, a fourth step of aligning the central axis of the base and the central axis of the pin so as to be in a straight line, And a fifth step of bonding the rod to be inserted into the rod so as to be in contact with the rod .

And a sixth step of caulking and fixing the fixing portion between the step and the opening and the opposite side of the fixing portion after completion of the fifth step, wherein the inclination of the front inclined portion is the same as that of the inclined surface And a feed line injection rod manufactured by the method for manufacturing a feed line injection rod according to the present invention.

As described above, the manufacturing method of the fillet injection rod according to the present invention minimizes the damage of the skin tissue, muscles, and blood vessels when inserted into the skin tissue in such a manner that the blunt distal end partitions the subcutaneous tissue rather than tearing the subcutaneous tissue or blood vessels, When the suture is inserted into the inserting rod, there is an effect of preventing the damage of the skin tissue due to the blunt tip of the inserting rod.

In addition, when inserting the suture into the inserting rod, an opening and an inclined surface of the pin are formed on one side of the outer circumferential surface so that the suture rises up the sloped surface of the pin and is discharged to the opening, thereby facilitating insertion of the suture. In addition, it is effective to increase the efficiency of the process in which the insertion needle is inserted into the skin tissue, and the structure is such that the tip is clogged when pulled out, and that the suture inserted by the slanted surface of the pin is smoothly discharged .

FIG. 2 is a flowchart of a method for manufacturing a fillet injection rod according to the present invention. Referring to FIG. 2, detailed components and manufacturing method of the present invention will be described below.

A method for manufacturing a fillet injection rod, comprising the steps of: forming a circular pipe-shaped base (10) having a front sloping portion (11) and a rear sloping portion (12) A tip 21 is provided at one end and an inclined surface 22 is provided at the other end and a step 23 is formed on the tip 21. [ A second step S20 of aligning the cylindrical pins 20 in which the tips 21 are aligned in the same direction and a third step S20 of aligning the slopes 22 so as to face upward, A fourth step S40 of aligning the center axis of the base 10 and the center axis of the fin 20 so that the center axis of the base 10 and the step 20 are aligned, Is inserted into the side base (10) where the base (13) is formed and the step (23) is engaged with the end of the base It characterized by comprising the step 5 (S50).

The insertion needle prepared by the method described above minimizes the damage of the skin tissue, muscles and blood vessels when inserted into the skin tissue in such a manner that the blunt tip 21 penetrates the subcutaneous tissues rather than tearing the subcutaneous tissues or blood vessels, Is inserted into the insertion rod, the blunt tip 21 of the insertion rod prevents the skin tissue from being damaged.

FIG. 3 is a perspective view of a feed rods according to the present invention, FIG. 4 is a side view of a feed rods according to the present invention, FIG. The components and the manufacturing method will be described as follows.

After the completion of the fifth step S50, the fixing portion 14 at the point where the opening portion 13 faces upward in the base 10 overlapped with the short length portion of the cylindrical pipe of the step 23 inserted And a sixth step S60 of fixing the pin 20 and the base 10 by caulking at least one of the left and right side fixing portions 15 and 15 of the fixing portion 14 and the fixing portion 15 And the inclined surface 22 is provided so that the slope of the slope 22 is equal to the slope of the slope 22 so that the suture T is fixed to the base 10, An opening 13 on one side of the outer circumferential surface and a clogged sloped surface 22 of the pin 20 are formed so that the suture rides on the sloped surface 22 of the fin 20 and is discharged to the opening 13 Making it easy to insert the suture. This makes it possible to increase the efficiency of the process of inserting the suture thread T into the insertion needle rod. In addition, since the structure in which the tip 21 is closed when inserting the insertion needle into the skin tissue, So that the inserted suture can be smoothly discharged without being pulled out together with the fillet injection rod.

In addition, in order to fix the base 10 and the pin 20, not only a caulking process but also a known bonding method may be used. In the fourth step S40 and the fifth step S50, 20 may be bonded to the base 10 by applying an adhesive to the step 23 before the base 20 is completely inserted into the base 10.

Although the present invention has been shown and described with respect to specific embodiments and applications thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with knowledge will know easily.
