Non-deformable anti-displacement urinary incontinence sling mesh and preparation method thereof

Abstract

The invention relates to the field of medical instruments, and provides a non-deformable anti-displacement urinary incontinence sling mesh and a preparation method thereof. The surface of the sling mesh is provided with a plurality of protrusions which are evenly spaced, the sling mesh is of a variable looping double-comb tissue structure, and the medical non-absorbable synthetic monofilaments are woven through two groups of different yarn laying tracks; the first group of monofilaments are fully threaded on a yarn guide comb, and each monofilament is laid on a corresponding knitting needle in the longitudinal direction to form a loop; and the second group of monofilaments are fully threaded on the other yarn guide comb, and each monofilament is laid on two adjacent knitting needles corresponding to the monofilament in turn in the longitudinal direction to form a loop. According to the urinary incontinence sling, the surface of the mesh is provided with the multiple evenly-spaced protruding structures, the postoperative displacement risk caused by sling looseness can be obviously reduced, the mesh is stable in structure, low in elongation and not prone to deformation, and the occurrence rate of postoperative urinary incontinence recurrence can be obviously reduced.

Description

technical field [0001] The application belongs to the technical field of medical devices, and relates to a urinary incontinence suspender, in particular to a non-deformable anti-displacement urinary incontinence suspender mesh and a preparation method thereof. Background technique [0002] Stress urinary incontinence refers to the involuntary leakage of urine from the urethral opening when abdominal pressure increases such as sneezing, coughing, laughing or exercise; for patients with moderate to severe stress urinary incontinence, tension-free mid-urethral sling is internationally recognized first-line treatment. Surgery usually uses a synthetic mesh belt for tension-free midurethral suspension. The mesh belt is placed on the side and rear of the middle urethra without tension. When abdominal pressure increases, the mesh belt creates pressure in the middle urethra to control urine leakage. Since postoperative patients still have the need to participate in social activities...

AI Technical Summary

Problems solved by technology

The sling mesh is a rectangular mesh with low longitudinal elongation, which can reduce the incidence of postoperative infection to a certain extent, but it still cannot effectively solve the problem of postoperative displacement of the sling mesh
