Knee joint tissue balance measuring device and method

Abstract

The invention belongs to the technical field of medical apparatus and instruments and discloses a knee joint tissue balance measuring device and method. The knee joint tissue balance measuring devicecomprises a ruler body and is characterized in that a slider sleeves the top of the ruler body and includes a left slider and a right slider, the left slider is fixed to the ruler body through a nut,the right slider is fixed to the ruler body through a fastening screw and can slide on the ruler body, a vernier scale is welded to the right side of the right slider, a push assisting rod is fixed tothe lower end of the vernier scale through a nut and sleeves the ruler body, the ruler body is welded to a handle, and a measuring jaw is welded to the top of the slider. By the knee joint tissue balance measuring device and method, the flexion-extension gap of knee joint soft tissue can be precisely measured, and whether the knee joint soft tissue is in a balance state or not can be determined from one aspect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a knee joint tissue balance measuring device and a measuring method thereof. Background technique [0002] The knee joint is mainly composed of femur, tibia and patella. With the aging of the social population, knee joint disease has become a common disease affecting the elderly. Total knee replacement surgery is an effective method for the treatment of advanced lesions. Knee replacement refers to replacing a knee joint that has been severely damaged and cannot travel normally with a prosthesis, and restores the balance between the knee joint and the flexion gap, the balance between the medial and lateral gaps and the corresponding soft tissue during the total knee replacement process. The balance of the knee joint is a very critical step, and the measurement of the extension and flexion gap between the knee joints is a very important indicator to determine wh...

Problems solved by technology

[0004] The detection results of the existing technology are relatively rough, which is not conducive to the collection of later data and cannot accurately target the problem

[0005] In the prior art, a manual booster rod is often used to push the slider, which makes the measurement accuracy poor; in the prior art, there are errors in the reading of data, which brings inconvenience to the measurement and cannot reflect the measurement situation truly enough; the existing The electronic reading device involved in the technology generally provides power for the battery, which increases the cost of the measuring equipment

[0006] In the prior art, the accuracy of the data obtained by the measurement method is poor, which cannot provide conditions for the accurate operation of the operation
