Abstract

The utility model discloses a barbed suture line, which comprises a line body with two ends, barbs which are cut on the line body and distributed along a spiral, and shaping glue filled in a cutting pit of the line body; the barb has point portion, basal portion, upper surface, inclined bottom surface and horizontal bottom surface, and the adhesion is strong, and the operation is effectual.

Description

Barb suture line

Technical Field

The utility model relates to a medical treatment operation stylolite especially relates to a barb stylolite.

Background

The existing barbed suture changes the concept that the traditional suture needs to be knotted, is convenient to use and trouble-saving, improves the operation efficiency, and is also applied as a cosmetic pull line.

The barb that conventional stylolite obtained through cutting process, because there is the tendency of reconversion, especially flexible barb is easy inwards to collapse under humid environment to, because the needle track that the needle formed when inserting can be greater than in the diameter and pull the stylolite that passes the tissue, the obstructed area and the limitation of distribution of barb make reverse tensioning fixed probably can not reach the effect of expectation, increased the operation degree of difficulty.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems and providing a barb suture line with strong fixing force and good operation effect.

In order to achieve the above object, the utility model adopts the following technical scheme: a barbed suture comprises a suture body with two ends, barbs which are formed by cutting on the suture body and distributed along a spiral shape, and sizing glue filled in a cutting pit of the suture body, wherein each barb is provided with a tip, a base, an upper surface, an inclined bottom surface and a transverse bottom surface and is obtained by bidirectional cutting which is performed by beveling firstly and then transversely cutting.

Further, the distance between adjacent barbs on a straight line is 0.3-0.8 mm, the included angle of the barbs is 45 degrees, and the cutting depth is about 20-30% of the line diameter.

Further, the helical angle between two adjacent barbs is 72 degrees or 60 degrees

Further, the wire body is a polymer monofilament.

Further, the sizing glue is silk fibroin.

Furthermore, one end of the wire body is connected with the suture needle, the other end of the wire body is provided with a stopper or a coil, and the barb inclines towards the other end far away from the suture needle.

Further, a suture needle is respectively connected to two ends of the line body, and two ends and interlude do not have the barb to the interlude is as the border, and the barb symmetric distribution of both sides, barb opening are towards the interlude.

The utility model has the advantages that:

1. the line body utilizes the reverse structure of barb to fix the suture after getting into the flesh tissue, plays the effect of exempting from to tie a knot.

2. Compared with one-way beveling, the utility model discloses a beveling is earlier followed the two-way cutting of crosscut for the barb of same cutting depth has bigger surface area, can produce stronger tissue fastening power.

3. The silk fibroin has good viscosity, can be well combined with the line body, has excellent biocompatibility, no immunogenicity and is degradable in the body, and the degradation product is safe and non-toxic and is filled in the cutting pit of the line body, so that the barb can not collapse inwards.

4. The barbs that the line body circumference distributes are many, are difficult to take place to deflect between line body and the wound tissue.

Detailed Description

The present invention will be further described with reference to the following specific embodiments and accompanying drawings.

Referring to fig. 1 to 4, a barbed suture comprises a thread body 1, barbs 2 and a sizing glue 3, wherein the barbs have a tip 21, a base 22, an upper surface 23, an inclined bottom surface 24 and a transverse bottom surface 25, and are obtained by a cutting device in a bidirectional cutting mode of firstly beveling and then transversely cutting the surface layer of the thread body, and the sizing glue 3 is filled in a pit 4.

The distance between adjacent barbs on a straight line is 0.3-0.8 mm, the included angle of the barbs is 45 degrees, and the cutting depth is about 20-30% of the line diameter.

The wire body is made of polymer monofilament.

Silk fibroin is adopted as the sizing glue.

Example 1

As shown in figure 1, the suture is a one-way barb suture, one end of the wire body 1 is used for connecting a suture needle, and the other end can be provided with a stop head or a coil. The helical angle between two adjacent barbs is 72 degrees.

Example 2

As shown in fig. 2, for two-way barb stylolite, two ends of the line body 1 are used for connecting the sewing needle respectively, and two ends and midrange do not have the barb to the interlude is as the border, the 2 symmetric distributions of barb of both sides, and the barb opening is towards the interlude. The helical angle between two adjacent barbs is 60 degrees.

The above description is only a detailed description of some embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily change or replace the present invention within the technical scope of the present invention.
