Rotator cuff patch and manufacturing method thereof

Abstract

The invention provides a rotator cuff patch. The rotator cuff patch comprises a fixing line at the bone surface end of the patch, an edge sealing side of the patch, an edge sealing side at the bone surface end, a threading hole, a rotator cuff patch body, a fixing line at the tendon end and an edge sealing side at the tendon end. The fixing line at the bone surface end of the patch is connected with the edge sealing side of the bone surface end through the threading hole; one end of the edge sealing side of the patch is connected with the edge sealing side of the bone surface end, and the other end is connected with the edge sealing side of the tendon end; and the fixing line at the tendon end is connected with the edge sealing side at the tendon end through the threading hole. The invention further provides a manufacturing method of the rotator cuff patch. According to the invention, a rotator cuff structure can be reconstructed after an operation, and the composite material has the characteristics of softness and good tensile property, is more easily attached to a bent bone surface, can be stretched in a limited manner when being stressed, can retract to an original state after the force disappears, provides long-term good mechanical strength and good biocompatibility, is beneficial to cell adhesion and graft-bone. Graft-tendon healing is facilitated, and postoperative early rehabilitation exercise and rotator cuff function recovery are facilitated.

Description

technical field [0001] The invention relates to the technical field of surgical repair operations, in particular to a rotator cuff patch and a manufacturing method thereof. Background technique [0002] Rotator cuff injury is one of the common causes of shoulder joint pain and dysfunction. Arthroscopic rotator cuff repair has become one of the most effective methods for rotator cuff tears that are not effective in conservative treatment. However, the healing of the rotator cuff is a complex process affected by both biomechanics and biology, which may be related to acute and chronic tears, tear size, degree of tendon degeneration, muscle atrophy, fatty infiltration degeneration, surgical technique and postoperative rehabilitation. Other factors are friendly. Studies have reported that the re-tear rate after clinical rotator cuff repair ranges from 20% to 40%. For huge rotator cuff tears or severely retracted rotator cuff tears, the surgical repair failure rate can be as high...

AI Technical Summary

Problems solved by technology

The disadvantage of this prior art is that the mechanical properties of the tendon stump and the mechanical properties of the patch are quite different, and the problem of poor healing or direct fracture cannot be well solved.
