Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0052] Such as figure 1 As shown, a segmented nano-coating modified artificial rotator cuff patch provided according to the present invention includes: humerus braided segment 1, tendon free fiber segment 2;

[0053] The upper part of the humerus braided segment 1 is provided with a bone end hole 3, and the bone end hole 3 runs through the inner surface and the outer surface of the humerus braided segment 1;

[0054] The lower end of the braided section 1 of the humerus is connected to the upper end of...

Abstract

The invention provides a segmented nano coating modified artificial rotator cuff patch which comprises a humerus woven section 1, a tendon free fiber section 2 and a pull ring 900. A capitulum hole 3 is formed in the upper portion of the humerus woven section 1 and penetrates through the inner surface and the outer surface of the humerus woven section 1. The lower end of the humerus woven section 1 is connected with the upper end of the tendon free fiber section 2. A tendon end hole 4 is formed in the lower portion of the tendon free fiber section 2 and penetrates through the inner surface and the outer surface of the tendon free fiber section 2. By means of the segmented nano coating modified artificial rotator cuff patch, mechanical properties of rotator cuff tissue can be improved after a rotator cuff injury repair operation. Meanwhile, in the aspect of biological performance, the features of tendon-bone healing tissue through which a rotator cuff and a bone are connected can be simulated. The structure can enhance the inherent healing potential of tendons, and accordingly the success rate of the rotator cuff injury repair operation is increased.

Description

technical field [0001] The invention relates to the field of surgical patches, in particular to an artificial rotator cuff patch modified with a segmented nano-coating. Background technique [0002] Rotator cuff tear is a common shoulder joint disease, and the incidence rate gradually increases with age. Rotator cuff tear is a common cause of shoulder joint pain, reduced mobility, and reduced function, accounting for about 60% of shoulder lesions. For patients with rotator cuff injuries who fail conservative treatment and patients with large rotator cuff injuries, surgical treatment is usually used to repair the torn tendon, so as to relieve pain and restore joint function. [0003] The tendon is the weak point in the rotator cuff repair process, especially when the defect is large, it is difficult to pull and try to fix the large torn rotator cuff tissue to the original attachment point before the injury. At this time, it is necessary to use the rotator cuff Structural en...
