Rotator cuff repairing surgery device, hollow limiting drilling bit, and operation method

Abstract

The invention relates to a rotator cuff repairing surgery device, a hollow limiting drilling bit, and an operation method. The rotator cuff repairing surgery device includes an aiming arm, a suture device, a sleeve, an aiming rod and a locking fastener. The hollow limiting drilling bit includes a drilling rod having an axial drilling hole. In operation, a PDS suture is reserved on the aiming arm, the suture device and the aiming rod are used to perform positioning, the hollow limiting drilling bit drills a bone tunnel, a PDS suture passes through the suture device, and then the reserved PDS suture is used to drive the PDS suture in the bone tunnel out from a through groove of the aiming arm, the PDS suture drives a suture for suturing a rotator cuff out, cross-bone tunnel transversal mouth-shaped tying is performed, and then the rotator cuff repairing surgery operation is completed. The rotator cuff repairing surgery device and the hollow limiting drilling bit are simple in structure, the sutures can be easily taken out, and the operation method is completed under arthroscopy monitoring; the surgery difficulty, the learning cost and the material cost is reduced, patient and social insurance economic burdens can be reduced, and the rotator cuff repairing surgery can be promoted to the greatest extent.

Description

technical field [0001] The present invention relates to rotator cuff tear surgery medical instrument, especially relates to a kind of operation device that utilizes minimally invasive surgery to carry out rotator cuff repair by bone medullary canal method, and the hollow limit drill bit used for the device, and the use of the device and the hollow How to operate limit drill. Background technique [0002] The rotator cuff, also known as the rotator cuff, is a group of tendon complexes that wrap around the humeral head. According to the degree of injury, rotator cuff tears can be divided into partial and complete tears, mostly caused by indirect violence. Rotator cuff tear is the main cause of shoulder joint pain and weakened shoulder joint function, especially for patients with full-thickness rotator cuff tear, if the rotator cuff repair operation is not performed in time, the tear area will gradually increase, which may eventually lead to Tendon retraction and irreversible...

AI Technical Summary

Problems solved by technology

However, no matter what method is used, the price of the repair materials involved is extremely expensive, and the operation is difficult, which requires a high level of personal skill of the surgeon; at the same time, the technical growth cycle of the shoulder arthroscopy surgeon is long, and he can Physicians who master this type of surgery are mostly concentrated in large medical institutions with specialized sports medicine departments, resulting in low popularity of this type of surgery, which is extremely unfavorable to the development of medical care
