Orthopedic Knee Surgery Position Fixation Workbench

Abstract

The invention discloses an orthopedics-department knee-joint operative position fixing working table. The orthopedics-department knee-joint operative position fixing working table comprises a fixing base, a foot fixing unit, a downward-pulling connecting rod unit, an upward-lifting connecting rod unit, a joint pulling sliding unit and a tendon tension measuring assembly. The foot fixing unit, the downward-pulling connecting rod unit, the upward-lifting connecting rod unit and the joint pulling sliding unit are all in sliding connection with the fixing base. The orthopedics-department knee-joint operative position fixing working table is convenient to use, the knee joint can be conveniently fixed at any angle, a joint gap can be sufficiently and stably exposed, the stable operation state can be achieved, iatrogenic injuries can be reduced, and operation time can be shortened; ligament fixing tension is digitalized, and the ligament original-tension reconstruction function is achieved.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to an orthopedic knee joint operation body position fixing workbench. Background technique [0002] Knee arthroscopic surgery is a necessary equipment for diagnosis and surgical treatment from the anteromedial and anterolateral spaces of the knee joint into the joint cavity through a laparoscope. During the operation, in order to fully expose the operative field in the narrow space of the knee joint, the surgeon must obtain a sufficient operative field by changing the position of the patient's affected leg. In the past, this kind of knee joint position change was completely done manually. During the position change process, the hand shake of the arthroscopic operator and the change of surgical marks in the operative field caused the operator to constantly adjust the position of the arthroscope and surgical tools. Adjustment times lead to longer operation time, and the probability of...

Problems solved by technology

In the past, this kind of knee joint position change was completely done manually. During the position change process, the hand shake of the arthroscopic operator and the change of surgical marks in the operative field caused the operator to constantly adjust the position of the arthroscope and surgical tools. The adjustment of times leads to a longer operation time, and the probability of iatrogenic damage to the articular cartilage surface is greatly increased

At the same time, because the body position is fixed and unstable, the body position is more random, which is not conducive to the training of standardized surgical techniques for basic doctors
