Embodiment 1

[0032] Using polypropylene monofilament fiber as raw material, after warping, it is designed to change the warp and satin structure, with two combs, one thread and one empty symmetrical lap yarn, and the fabric weaving parameters are set to GB1: 1-0-1 / 1-2-2 / 2- 3-2 / 2-1-1 / / ; GB2: 2-3-2 / 2-1-1 / 1-0-1 / 1-2-2 / / , the warp knitting holes of the obtained gray cloth are rhombus ( figure 2 ), the side length of the rhombus is 3mm. The warp knitting large hole and the dividing line are also woven and formed on the warp knitting machine. The diameter of the warp knitted large hole is 5mm. Finally, the final product is obtained after shaping.

Embodiment 2

[0034] The same method described in Example 1 was used to make the rotator cuff patch ( image 3 ), only add a third bar for weft insertion when weaving.

Embodiment 3

[0036] The rotator cuff patch ( Figure 4 ), only adjust the fabric weaving parameters to GB1: 1-0-1 / 1-2-2 / 2-1-2 / 2-3-2 / 2-1-1 / 1-2-1 / / ; GB2: 2-3-2 / 2-1-2 / 2-3-2 / 2-0-1 / 1-2-1 / 1-0-1 / / .

Abstract

The invention relates to a patch for treating rotator cuff injuries, in particularly to a patch applicable to repairing huge rotator cuff tear. The patch is woven through the warping technology, is low in mass and not likely to be disengaged and has the good clipping performance; due to the special hole and boundary design, corresponding clipping and sewing fixation are easily perfrmed according to surgical needs. The rotator cuff patch is good in biomechanical intensity, can provide enough mechanical support for rotator cuff joints, avoids patch creep deformation and improves the surgical efficiency and the treatment effect.

Description

technical field [0001] The invention relates to the field of surgical repair operations, in particular to a patch for treating rotator cuff injuries. Background technique [0002] The rotator cuff is the main anatomical structure that maintains the stability of the shoulder joint. It is a group of muscles with similar functions mainly composed of the supraspinatus, infraspinatus, teres minor, and subscapularis. The tendons of the four muscles Partially forms a cuff-like structure at the anatomical neck of the humeral head, surrounds the upper, back and front of the shoulder joint, and attaches to the shoulder joint capsule, so the rotator cuff tissue plays an important role in the stability of the shoulder joint. [0003] Rotator cuff injury is a common disease, which is common in young adults and the elderly. It is caused by traumatic injury or degeneration of the rotator cuff tendon due to abnormal anatomical structure. According to the different causes of rotator cuff in...
