Embodiment

[0036] This embodiment provides a fixation structure for tibial tubercle fractures, such as image 3 As shown, it includes: a wrapping structure, which is suitable for wrapping the tibial tubercle fracture fragment and the bone tissue around the fracture fragment, and fixedly connects the tibial tuberosity fracture fragment and the bone tissue around the fracture fragment through several screws. Tissue; a hooking structure, fixedly arranged on the wrapping structure, suitable for hooking on the junction of the patellar ligament and the fracture fragment.

[0037] The fixation structure for tibial tubercle fractures in this embodiment includes a wrapping structure and a hooking structure. The wrapping structure is suitable for wrapping the fracture block at the tibial tubercle position and the bone tissue around the fracture block, and can be connected to the fracture block by several screws. The fragment is fixedly connected with the bone tissue, and the hook structure is fixe...

Abstract

The present invention provides a fixation structure for tibial tubercle fractures, comprising: a wrapping structure, suitable for wrapping tibial tubercle fracture fragments and surrounding bone tissue, and fixed by screws; a hook structure, fixedly arranged on the wrapping structure, suitable for The hook hangs at the junction of the patellar ligament and the fracture fragment. The fixation structure of the present invention adopts a wrapping method to reset and squeeze the bone tissue around the fracture block and wrap it tightly, and fix it by using several screws; after the hook structure is set, the hook The structure is hooked at the junction of the patellar ligament and the fracture fragment, preventing the patellar ligament from pulling the fracture fragment away. The strength against the patellar tendon pulling the fragment is from the whole wrapping structure instead of a single screw; through the above settings, the single position of the bone is avoided Excessive force can avoid comminuted fractures caused by fixing the fracture block; for osteoporosis patients, it can also be used according to the situation.

Description

technical field [0001] The invention relates to the technical field of medical devices for auxiliary fixation of fractures, in particular to a fixation structure for tibial tubercle fractures. Background technique [0002] Total knee arthroplasty is an effective way to treat middle-advanced arthritis, but knee extensor device damage is a taboo for total knee arthroplasty. The premise of total knee arthroplasty must be that the patient's knee extensor device is complete, otherwise the treatment effect will be greatly affected . Such as figure 1 As shown, the knee extensor device mainly includes the quadriceps tendon 01, the patella 02, and the patellar ligament 03. In reality, there are some patients who have a complete knee extensor device before total knee arthroplasty, but trauma occurs after total knee arthroplasty, resulting in damage to the knee extensor device. One type of injury is a fracture at the tibial tubercle 04 position. After the fracture, because the patel...
