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

[0033] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0034] The present invention provides a kind of preparation method of the surgical suture that prepares wrapped structure, comprises the following steps:

[0035] (1) Preparation of filaments: melting the polymer material used to produce the core yarn 1, and preparing filaments by melt spinning, including melting, filtering, metering, spinning, side blowing cooling, stretching, shaping, winding step;

[0036] (2) Production of core yarn: combine and twist multiple filaments prepared in step (1) to obtain core yarn 1;

[0037] (3) Production of wrapping yarn: melt the polymer material used to produce wrapping yarn 2, and prepare coarse denier yarn by melt spinning method; then heat the coarse denier yarn evenly to soften the coarse denier yarn; The final coarse denier yarn passes through the cooling device to cool the coarse denier yarn at inter...

Abstract

The invention relates to the technical field of surgical suture lines and particularly relates to a preparation method of the surgical suture lines with wrapping structures. The method comprises the steps of: preparing filaments, producing core yarns, producing wrapping silks, producing the surgical suture lines and the like, and the finally prepared surgical suture lines comprise the core yarns and the wrapping silks; the core yarns are formed by twisting the plurality of filaments; the wrapping silks are provided with thick knots distributed uniformly at intervals and wrap on the core silks;when the wrapping silks are straightened, the interval between two adjacent thick knots on the wrapping silks is 4-15mm; when the wrapping silks wrap on the core yarns, the interval between the two thick knots is 3-13mm along the axis direction of the surgical suture lines. The preparation method is simple in process and easy in operation, and the prepared surgical suture lines prepared have theadvantages of wrapping structures, slip prevention and low production cost; in addition, the knotting time in the process of surgical suture also can be saved, and the pain of a patient can be relieved.

Description

technical field [0001] The invention relates to a surgical suture, in particular to a preparation method of a wrapped structure 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 knott...
