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 invention provides a fixing structure for tibial tuberosity fracture. The fixing structure comprises a wrapping structure and a hooking structure, the wrapping structure is suitable for wrapping atibial tuberosity fracture block and bone tissues around the tibial tuberosity fracture block and is fixed by screws, and the hooking structure is fixedly arranged on the wrapping structure and is suitable for being hooked at the joint of the patellar ligament and the fracture block. According to the fixing structure, a wrapping method is adopted, the fracture block and bone tissues located around the fracture block are tightly wrapped after being reset and squeezed, and fixing is achieved through the multiple screws; after the hooking structure is arranged, the hooking structure is hooked atthe joint of the patellar ligament and the fracture block, the fracture block is prevented from being pulled to be deviated by the patellar ligament, and the force for resisting the patellar ligamentto pull the fracture block to be deviated comes from the whole wrapping structure instead of a single screw; and through the arrangement, excessive force is prevented from being applied to a single position of a bone, and the problem of comminuted fracture caused by fixing the fracture block can be avoided as much as possible. For patients with osteoporosis, the fixing structure can also be adopted according to conditions.

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...
