Problems solved by technology

However, this kind of surgical suture is not easy to produce, and because the material of the surgical suture is generally soft and soft, only using the barbed structure cannot completely replace the knot.

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0024] The invention provides a kind of preparation method of the anti-slip surgical suture, comprising the steps of:

[0025] Step (1) Melt spinning: Melt the polymer material for preparing surgical sutures, and prepare coarse denier silk threads by melt spinning;

[0026] Step (2) heating: uniformly heating the coarse denier yarn prepared in step (1), so that the coarse denier yarn becomes soft;

[0027] 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 ellipses evenly distributed intermittently along the axial direction on the pressure roller. Shaped protrusion, the minor axis direction of the elliptical protrusion is consistent with the axial direction of the pressure roller; the wi...

Abstract

The invention relates to the technical field of surgical sutures and concretely relates to a preparation method for an antiskid surgical suture. The preparation method comprises steps of fusion spinning, heating operation, filament pressing, hole drilling operation and cooling and winding operation. The surgical suture prepared by the method comprises steps of first parts and second parts, whereinthe first parts and the second parts are distributed at intervals; a cross section width of the first parts of the surgical suture is even; a cross section width of the second parts is greater than the cross section width of the first parts; the second parts are oval; an elongated hole is formed in each oval shape; the length of the hole is no less than the length of a short shaft of each oval shape; and the width of each hole is no less than the cross section width of the first parts. Compared with the traditional surgical suture, the surgical suture prepared by the method is antiskid, can easily pass through muscles, and requires low production cost; and binding time during the surgical suturing process can be saved, so patient pain can be reduced.

Description

technical field [0001] The invention relates to a surgical suture, in particular to a preparation method of an anti-slip 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...
