Instrument for ankle joint injury ligament reconstruction and operation method thereof

Abstract

The invention provides an instrument for ankle joint injury ligament reconstruction and an operation method thereof. The instrument comprises a guiding device, a guide needle, a leading device and a miniature fixator, wherein the guiding device comprises an operation handle and a guide pipe; one end of the guide pipe is fixedly connected with the vertical side wall of the operation handle; a through hole communicating with the guide pipe is formed in the operation handle; the guide needle is in a rod shape and can penetrate through the guide pipe; a clamping traction end is arranged at one endof the guide needle; the leading device comprises a first leading section, a second leading section and a third leading section; and the miniature fixator comprises a square frame, and two rod clawswhich are symmetrically distributed up and down are symmetrically arranged on the front portion and the rear portion of the right side wall of the square frame respectively. By means of the guiding device, the guide needle and the operation method of the leading device, ligament implantation can be smoothly reconstructed, ligament reconstruction operation can be smoothly achieved in an assisted mode through the instrument, and the operation effect is good.

Description

technical field [0001] The invention relates to an apparatus for reconstruction of ankle joint injury ligaments and an operation method thereof. Background technique [0002] Ankle sprains, ankle fractures and other traumas can often lead to damage to ankle ligaments, such as the anterior talofibular ligament, calcaneofibular ligament, medial triangular ligament, etc., which affect the stability of the ankle joint and lead to foot dysfunction. Ligament reconstruction surgery is required in clinical situations such as persistent ankle joint instability and repeated ankle sprains. Due to the flat anatomical structure of the tibial triangular ligament and the fibular collateral ligament of the ankle joint, the interior is cord-like, and the width of the start and end points is inconsistent, etc., the complete ligament presents a fan-shaped stress arc on the tibial and fibular sides of the ankle joint. structure to adapt to our walking gait and maintain stability. At present, ...

AI Technical Summary

Problems solved by technology

At present, ligament reconstruction methods mostly use free or allogeneic tendon, peroneus brevis tendon and other materials, and use simple anchors, fibula double-channel and single-channel fixation methods such as tendon and bone for reconstruction. There are tendon fixation failures, stress concentration that cause pain and ankle joint movement. Limitation, application of the peroneal tendon leads to long-term weakness of the ankle joint and subtalar joint and loss of dynamic stability, and anatomical reconstruction cannot be performed, which affects the patient's walking function
