Ankle joint anterior fusion distraction osteotomy device

Abstract

The invention provides an ankle joint anterior fusion distraction osteotomy device, which is composed of a distal tibia fixation module and a sliding gap distraction module. The anterior and posteriorsurfaces of the distal tibial fixation module are provided with a plurality of vertical fixation needle tracks which are parallel to each other, and an oblique fixation needle track which is at an angle with the direction of the vertical fixation needle tracks; the distal tibial fixation module and the sliding gap distraction module are fitted through a slider slot and can be locked after slidingadjusting is in place. The sliding gap distraction module has a distraction arm with a space between the distraction arms to accommodate the passage of the osteotomy instrument. After the distal tibial osteotomy is completed, the invention is used for expanding the ankle joint space, determining the distraction distance of the ankle joint space and the osteotomy plane of the upper talus accordingto the completed distal tibial osteotomy plane of the patient, maintaining the space and the relative position between the distal tibial osteotomy plane and the upper talus, and facilitating the upper talus osteotomy.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgical instruments, in particular to an anterior ankle fusion distraction osteotome. Background technique [0002] Ankle arthritis is a disabling disease, and its treatment can be said to have both benefits and challenges for both patients and medical workers. The most common clinical symptom of patients with ankle arthritis is abnormal gait, which is often accompanied by pain in knee joints, hip joints, and even back, which seriously affects the health of the whole body. Ankle fusion surgery is still one of the common orthopedic operations so far. Post-traumatic ankle arthritis, osteoarthritis, ankle tuberculosis and failure of ankle joint replacement are the main indications for ankle fusion surgery. [0003] Although the postoperative effect of ankle arthrodesis is not perfect, it can restore the stability of the ankle joint and achieve the purpose of relieving pain. On the premise of cor...

Problems solved by technology

As a result, there is a large bias in the osteotomy of different surgeons, and it is impossible to implement an individualized surgical plan according to the specific situation of the patient, which cannot meet the requirements of precision and individual medical care. Therefore, the ankle joint fusion is performed according to the tibial alignment of the patient. Confirmation and preparation of surgical osteotomy surface is imperative
