[0002] In the field of medical surgery, especially for repair of rotator cuff tears, internal and external nails are commonly used fixation tools. Internal nails are mainly used to provide a stable support point inside the bone to facilitate suturing of damaged tissues, while external nails use interface screws to ensure the firmness of the suture. In recent years, with the development of minimally invasive surgical technology, wire anchors have gradually become popular in clinical applications due to their simple operation and low trauma.

[0003] Currently, in order to fix the rotator cuff on the humerus, doctors usually drill two bottom holes in the bone and then insert two wire anchors in sequence. This process involves multiple steps, including drilling, inserting the first anchor, drilling the second hole, inserting the second anchor, etc. In addition, special tools are needed to adjust and fix the position of each anchor to ensure that it is accurately embedded in the predetermined position.

[0004] However, this traditional method of implanting wire anchors still has some shortcomings. Its implantation method mainly relies on manual insertion, which not only increases the time and complexity of the operation, but also may cause increased pain for the patient and excessive physical exertion for the doctor due to multiple operations. Especially when the position of the anchor needs to be precisely controlled, this method is prone to errors, thus affecting the overall effect of the operation. Therefore, how to improve the efficiency and accuracy of wire anchor implantation has become a technical problem that needs to be solved urgently. Summary of the invention

Specifically, in the first step, a basic hole is drilled in the bone in advance to prepare for the subsequent implantation of the anchors 7, thereby reducing the time for intraoperative adjustment; in the second step, the two anchors 7 with sutures 9 are respectively fixed on the fixed push rod 2 and the movable push rod 3, thereby ensuring the stability and accuracy of the anchors 7; in the third step, the two matching anchors 7 are placed in the designated position through the surgical incision, and the anchor 7 on the fixed push rod 2 is placed above a basic hole, thereby ensuring the initial positioning of the anchor 7; in the fourth step, the two anchors 7 are placed in the fixed push rod 2, thereby ensuring the initial positioning of the anchor 7; in the fifth step, the two anchors 7 are placed in the fixed push rod 2, thereby ensuring the initial positioning of the anchor 7. In the first step, the anchor nail 7 on the movable push rod 3 is accurately placed above the other basic hole by controlling the opening and closing mechanism and the locking mechanism, thereby realizing the accurate positioning of the two anchor nails 7 at the same time; in the fifth step, the movable push rod 3 is fixed by the locking mechanism, and the handle 1 or the push rod is hit with a hammer, so that the two anchor nails 7 are smoothly inserted into the basic hole until they are fully inserted, thereby ensuring the firmness of the anchor nails 7; in the last step, the movable push rod 3 is rotated to the side of the fixed push rod 2 by controlling the clamping mechanism and the locking mechanism, so that the second fitting portion 32 is fitted with the first fitting portion 22, and taken out from the incision, thereby simplifying the operation of removing the tool and further improving the overall efficiency of the operation.
