Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0025] The invention provides a kind of preparation method of the anti-slip surgical suture, comprising the steps of:

[0026] Step (1) Melt spinning: Melt the polymer material for preparing surgical sutures, and prepare coarse denier silk threads by melt spinning;

[0027] Step (2) heating: uniformly heating the coarse denier yarn prepared in step (1), so that the coarse denier yarn becomes soft;

[0028] Step (3) Filament pressing: The heated coarse-denier silk thread is intermittently extruded through the extruding device. The extruding device includes a pressure roller and a stressed groove. There are multiple protrusions evenly and intermittently distributed along the axial direction on the pressure roller. , the cross-section of the protrusion has a first end and a second end, the first end is semi-elliptical, the second end is rectangular...

Abstract

The invention relates to a preparation method of a knotting-free surgical suture line. The method comprises the steps of melt spinning, heating, wire pressing, punching, cooling, winding and the like.The surgical suture line prepared through the method comprises a first portion and a second portion distributed in a spaced mode, the width of the section of the first portion is uniform, the width of the section of the second portion is larger than that of the first portion, the first end of the second portion is in arc smooth transition with the first portion, the edge of the second end of thesecond portion is perpendicular to the axial direction of the surgical suture line, a sawtooth portion is arranged between the two ends of the second portion, and a long-strip-shaped hole is formed inthe center inside the second portion. Compared with a traditional surgical suture line, the surgical suture line has the advantages of being free of knotting, capable of easily penetrating through muscles and low in production cost, can shorten the knotting time in the surgical suture process and relieves patient's pain.

Description

technical field [0001] The invention relates to a surgical suture, in particular to a method for preparing a knot-free surgical suture. Background technique [0002] The traditional surgical sutures are non-absorbable sutures. Using this kind of sutures in the postoperative suturing process will cause greater trauma, and the sutures need to be removed after the wound heals, causing secondary trauma and longer recovery time; And the suture is generally a whole line, and it takes a lot of time to thread the needle before the operation. When continuous suture is required, several knots are often tied after the first stitch to prevent the suture from slipping. However, due to the limited space at the wound site, this method of operation will not only add some additional complicated steps, but also prolong the operation time and anesthesia time accordingly, resulting in an increase in the risk factor of the patient. [0003] In order to reduce knotting or even not knotting and s...
