Description
Technical Field
The utility model relates to the field of rotator cuff therapeutic devices, in particular to a rotator cuff repair and fixation system.
Background
The rotator cuff is a set of muscle and tendon complexes wrapped around the humeral head, and these tendons stabilize the humeral head on the scapula, which plays an extremely important role in maintaining the stability of the shoulder joint and the movement of the shoulder joint. Rotator cuff injury is a common condition of the shoulder joint, often resulting in degeneration of rotator cuff tissue due to repeated anterior and abduction movements of the shoulder joint, which in turn results in rotator cuff tearing.
Rotator cuff tears often involve prolonged overuse of the shoulder, limiting the patient's daily life, and in addition to rotator cuff complete tears, i.e. complete separation of tendons from bones, there are also considerable patients who only present with partial tears, lesions where the remainder of the tendons currently need to be completely separated from bones in order to treat the partially torn region with suture anchoring.
At present, the clinic relies on a suture anchoring and fixing method by using a belt wire, firstly, anchoring and fixing the belt wire on the scapula, then, penetrating the wire through the rotator cuff tissue, and then knotting and suturing, and finally, suturing and fixing rotator cuff tendon on the anatomical insertion region of the humerus.

Detailed Description
The technical scheme of the utility model is further described by specific examples.
As shown in fig. 1 to 3, the rotator cuff repair fixation system according to the present embodiment includes a bone plate 1 and an anchor 4, and the bone plate 1 includes a connection portion 11, an anchoring portion 12, and a transition portion 13. The lower surface of the connecting part 11 is provided with a fixed spike 2, and the fixed spike 2 is used for connecting with the rotator cuff. The anchor portion 12 is provided with an anchor hole 3, and an anchor 4 can be inserted into the anchor hole 3 for connection with the humerus. The transition portion 13 connects the connection portion 11 and the anchor portion 12.
In the embodiment, the fixed gripper 2 is convenient for grabbing and fixing the rotator cuff soft tissues, so that complex operations such as threading and line knotting are reduced, and the operation time is shortened.
As shown in fig. 3, the number of the fixed claws 2 is multiple, and the fixed claws are arranged in a rectangular array, so that the contact area with the rotator cuff can be increased, the rotator cuff is effectively prevented from being broken again, the number of the fixed claws 2 can be increased or decreased according to the use requirement, and the contact area between the bone plate 1 and the rotator cuff soft tissue covering of the claw can be adjusted.
As shown in fig. 2 and 3, the bone plate 1 has a stepped structure, and the plane of the connecting portion 11 and the plane of the anchoring portion 12 do not coincide. In particular, the bone plate 1 may be adapted to the anatomy at the humeral rotator cuff.
As shown in fig. 3, the fixed jaw 2 is in a circular arc shape, and the tip of the fixed jaw 2 is bent toward the direction of the anchoring portion 12, so that the rotator cuff can be pulled, and the rotator cuff is prevented from falling out of the fixed jaw 2.
As shown in fig. 2 and 3, the transition portion 13 is provided with the weight-reducing groove 6, and the weight-reducing groove 6 is provided along the longitudinal direction of the bone plate 1, so that the weight of the whole structure can be reduced, and the influence on the human body can be reduced.
