Ligament tibia dead point avulsion fracture fixing device and matched operation method thereof

Abstract

The invention relates to a ligament tibia dead point avulsion fracture fixing device, and the device comprises a first fixed block, a second fixed block and a suture, the first fixed block, the secondfixed block and the suture are used in a matched mode, a plurality of wings extend out of the periphery of the first fixed block and the periphery of the second fixed block, concave areas are formedbetween the wings, and clamping grooves are formed in the concave areas of the first fixed block. Holes are formed in the concave areas of the second fixed blocks. Through an arthroscope technology, tissues near a fracture block are cleaned to expose a fracture broken end; a tunnel is dug and penetrates through the bone block to the broken end of the fracture; the first fixed block is arranged ata tunnel portal on the inner side of the tibia, and the second fixed block is arranged at a tunnel portal at the fractured end; two arc-shaped rope loops are formed at the other end of the suture; thetwo arc-shaped rope loops penetrate through the tunnel and are arranged in the two opposite clamping grooves of the first fixed block in a sleeved mode respectively; and sewing thread end can be tightened. The device can be matched with an arthroscope to realize minimally invasive fixation of a fracture broken end, a small incision shortens postoperative rehabilitation time of a patient, and painand treatment cost of the patient are reduced.

Description

technical field [0001] The invention relates to a fixing device and an operation method using the fixing device, belonging to the field of medical operations. Background technique [0002] Avulsion fracture of tibial insertion of ligament (for example, avulsion fracture of tibial insertion of posterior cruciate ligament). The traditional surgical approach is to position the patient in a prone position and incise the popliteal fossa to expose the fracture. Internal fixation of the fracture. Generally, it is fixed by two left and right metal hollow nails. The internal fixation can be removed 12 months to 18 months after the operation. [0003] This plan is a traditional surgical procedure. The popliteal fossa is rich in nerves and blood vessels, and the risk of incision is high. And when the fracture fragment is large and complete after incision, it is easier to fix it with metal hollow nails. If the bone is small and broken, the metal hollow screw is difficult to hold, w...

AI Technical Summary

Problems solved by technology

The second incision operation for removing the nails will bring great losses to the patients and their families both economically and physically and mentally.
