AI Technical Summary
Technical Problem
In arthroscopic Latarjet surgery, the uneven and inconsistent drilling positions of the coracoid process lead to a high probability of coracoid process fracture, which is difficult to avoid with traditional fixation methods, thus affecting the success rate of the surgery.
Method used
Design a drilling positioner, including a handle and a positioning head. The positioning head is provided with anti-slip texture and multiple positioning holes to stabilize the position of the drill bit, reduce the risk of slippage, and ensure drilling accuracy and consistency.
Benefits of technology
It improves the stability and precision of drilling, reduces the risk of coracoid fracture, lowers the probability of surgical failure, and improves the safety and efficiency of the operation.

Abstract
The utility model relates to the technical field of medical instruments, in particular to a punching positioner which comprises a handle and a positioning head, the handle comprises a connecting end and a holding end, and the holding end provides a grabbing position; the positioning head is connected with the connecting end part, a drill bit positioning hole is formed in the positioning head, and anti-skid grains are arranged on the end face, abutting against the to-be-punched part, of the positioning head. According to the positioning drill bit, the friction force between the positioning head and the to-be-drilled part of the patient can be increased through the design of the anti-skid lines, the stability of the positioning drill bit is improved, and the slippage risk is reduced. Therefore, operation complications such as coracoid fracture can be avoided, and the risk of operation failure is reduced.
