Problems solved by technology

This will bring about two problems: First, the biggest feature of knitwear is "detachability". Although the open state has been heat-set, it cannot be completely set.
Secondly, because the edge has been shaped, the material is easy to harden, and the monofilament in the open state will have burrs, resulting in an obvious foreign body sensation after implanting in the human body.

Embodiment 1

[0020] (Example 1, braided suspension belt)

[0021] See figure 1 , the braided suspension belt of this embodiment includes a middle structure 1 and edge structures 2 located on both sides of the middle structure 1 . The middle structure 1 is a plain warp weave woven with two polypropylene monofilaments; the edge structure 2 is a chain weave woven with two multifilament materials. The edge structure 2 is made of polypropylene multifilament material. The width of the braided suspension belt is 1-2cm; the pores on it are 2-2.5mm.

Embodiment 2

[0022] (Example 2, braided suspension belt)

[0023] still see figure 1 , The structure of the braided suspension belt of this embodiment is the same as that of Embodiment 1, except that the edge structure 2 is made of polyester multifilament material.

Embodiment 3

[0024] (Embodiment 3, braided suspension belt)

[0025] still see figure 1 , the braided sling structure of this embodiment is the same as that of Embodiment 1, except that the edge structure 2 adopts a degradable polylactide copolymer multifilament material, which is composed of 90% glycolide and 10% Spinning of lactide copolymer. After the edge structure woven with this material is implanted into the human body, its strength degrades to about 60% in two weeks, about 40% in three weeks, and basically zero after five weeks. The double-braided polypropylene monofilament used in the middle structure of the braided sling is a non-absorbent material that will not be degraded and softened by tissue enzymes. During the operation and for a relatively long period of time, the braided sling will not fall apart, and with the growth of human fibrous tissue, when the strength of the degradable material used for sealing the two edges of the braided sling is gradually degraded, the middle...

Abstract

The invention discloses a braided suspension strap and a braiding method thereof, wherein the braided suspension strap comprises a middle structure and edge structures positioned at the two sides of the middle structure; the middle structure is a warp flat tissue braided by two polypropylene monofilaments; and the edge structures are chain braiding tissues braided by two multifilament materials. The braided suspension strap comprises the middle structure and the edge structures; and the edge structures are made into the chain braiding tissues made of the multifilament materials, the states of edge opening and running caused by the traditional whole-piece cutting is broken through, the monofilaments are soft, the chain braiding is non-run, and the foreign body sensation implanted to a human body is greatly reduced.

Description

technical field [0001] The invention relates to the field of implantable medical devices, in particular to a braided suspension belt and a braiding method thereof. Background technique [0002] Women's stress urinary incontinence is a common disease in middle-aged and elderly women. According to statistics, the incidence rate of this disease in women over 50 years old is more than 30%. The method of treating this disease at present mainly is to use surgical operation, adopts urethra, bladder neck suspension to improve the sagging urethra suspension. Thereby, various urethral straps have also been designed in order to cooperate with the application of suspension. The commonly used suspender is a suspender cut from a whole piece of knitwear, and the monofilament at the edge is open. This will bring about two problems: First, the biggest feature of knitwear is "detachment". Although the open state has been heat-set, it cannot be completely set. Secondly, because the edge has...
