Description

Technical Field [0001] The present invention relates to a sewing rope manufacturing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an apparatus for manufacturing a picked rope having projections, and more particularly, to a picked rope manufacturing apparatus having a protrusion capable of improving the productivity of a picked rope having protrusions with superior soldering effect due to increased volume.

'Stitching', which is called 'stitching therapy', does not cut the skin of the body and pulls the skin or muscles tightly to improve the wrinkles or to keep the skin tissue in a resilient state. To be able to maintain.

That is, as shown in FIG. 5, the stitching procedure is performed in a state in which the needle rope A is inserted into the rope hole of the medical needle N having a small diameter of several millimeters or less, And the tip of the needle is positioned below the skin wrinkle (W) of the patient who needs improvement of the wrinkle. In this state, the needle of the needle, which is placed inside the skin tissue by the operator pressing the finger near the epidermis, (N) is released from the skin tissue in a state in which the needle (A) is pressed and fixed, only the solicited rope inserted into the needle is left in the skin tissue. After that, the remaining staple rope inside the skin tissue is melted and absorbed into the body.

At this time, the feeder rope becomes a factor that induces wound stimulation in the skin tissue, thereby promoting cell activity such as the production of an immune substance such as elastin or collagen, which heals the wound. Thus, the body rope- It is possible to maintain the lifting state in which the skin tissue is pulled up due to the volume feeling caused by the immune substance generated around the rope, so that the stretched skin is maintained in a taut state, the wrinkle is stretched and the elasticity is improved, It is possible to obtain various effects such as improving circulation and lymph circulation and improving skin moisture.

The suture ropes used in such a stitching procedure mainly use surgical sutures made of materials that can be absorbed into the body and absorbed within the skin tissue. For example, polylactic acid or Polydiaxonone ), A copolymer of lactic acid and glycolic acid, and a material capable of being absorbed in vivo such as poly-L-lactide-acid and polycaprolactone copolymer , It is not necessary to remove it after it is injected into the body, and there is no scar on the skin after the sold-out procedure, and only a little erythema is present, so that it does not interfere with daily life and has various therapeutic effects and side effects Dermatology, plastic surgeons, and oriental clinics, and so on.

On the other hand, the initial loading line rope used in the sold-out procedure is made of a general straight rod type so that when the feed rope is inserted into the skin tissue using a needle, it melts in the skin tissue and is absorbed into the body, The skin elasticity is improved and the skin wrinkles are spread by the lifting effect. However, there is a problem in that the lifting effect is not large with only one strand rope having a small cross-sectional diameter.

Therefore, in order to lift deep or wrinkled skin with a large number of wrinkles, it is necessary to inject a large number of wicker ropes into the skin tissue of a limited area, so that the needle must repeatedly penetrate into the skin tissue, In addition, there has been a problem that the skin is damaged in the skin tissue by the repeatedly penetrating needles, thereby increasing the risk of side effects.

In addition, when the feeder rope melts in the body and is absorbed into the skin tissue, it usually takes a few months. In the meantime, when there is severe movement in the skin tissue of the feeder rope, the position of the feeder rope injected into the skin tissue changes, The lifting effect is generated in a form different from the intention of the practitioner, thereby deteriorating the effect of the stall procedure.

In recent years, to improve the bulkiness of the pick-up rope and to improve the fixing power of the pick-up rope introduced into the skin tissue, a pick-up rope having a protrusion formed on the surface of the pick rope has been developed. It is possible to prevent the movement of the pick-up rope in the skin tissue by increasing the bonding force between the pick-up rope and the skin tissue introduced into the skin tissue, thereby causing a lifting effect according to the desired shape of the operator, , The effect of the sold-out procedure is improved and the use rate thereof is gradually increasing.

On the other hand, when manufacturing the pick-up rope having the protrusion as described above, generally, a bio-absorbable polymer material is spun to form a pick-up rope having a circular cross section, and then a knife is sloped from the surface of the pick- And then the incision is raised so as to form the protrusion.

Patent Registration No. 10-1213272 (December 18, 2012) Patent Registration No. 10-1440224 (Apr. 15, 2014) Patent Registration No. 10-1449107 (Apr.

In the prior art for manufacturing a pick-up rope having a projection as described above, slip occurs frequently in the process of sloping the blade at the surface of the rope with a circular cross section, so that the cutting depth due to the blade is not kept constant There is a problem that the protrusions formed on the surface of the pick-up rope are not uniform in size, and the defect rate in the manufacturing process deteriorates the productivity.

Further, in order to form protrusions having a sufficient size in the process of cutting a part of the rope with a circular cross section and forming the protrusions, the depth of incision cut by the blade is deepened. When the depth of incision is too deep , The cross-sectional area of the pick-up rope is reduced, and the tensile strength is rapidly lowered.

Thus, in order to secure a cross-sectional area for maintaining a stable tensile strength, the strand rope having the projections of the prior art is formed so that the projections formed on the surface of the rope are located in a staggered manner so that the increase rate of the surface area by the projections is not high. There is a drawback that the improvement of the effect of the sold-out procedure is insignificant.

Therefore, it is inevitable to develop a feeder rope manufacturing apparatus having a protrusion with an increased volume effect by forming more protrusions at a short distance and thereby improving the effect of the soldering process.

The present invention has been made in order to solve the conventional problems as described above,

The apparatus for manufacturing a picked rope having the projections of the present invention has the effect of significantly improving the productivity of the pick-up rope, in which protrusions are formed to improve the bulkiness and the bonding strength with the skin tissue.

In addition, it is possible to variously change the size, shape and spacing of protrusions formed on the pick-up rope, and thus it is possible to easily produce a pick-up rope having an excellent lifting effect due to the volume feeling acting in the skin tissue.

In addition, it is possible to form uniform and precise protrusions in the process of forming protrusions on the surface of the pick-up rope, and to secure a sufficient cross-sectional area for maintaining the tensile strength despite the increase in volume, It has the effect of mass production with productivity.
