Abstract

The invention relates to a measuring system and method for a knee joint gap. The measuring system for the knee joint gap comprises a base, a first abutting part, a second abutting part and a pluralityof tracers, the first abutting part and the second abutting part are installed on the base and can move relatively, the first abutting part is used for abutting against the tibia, the second abuttingpart is used for abutting against the thighbone, and the size of the gap between the thighbone and the tibia can be measured by measuring the positions of the tracers connected with the first abutting part and the second abutting part correspondingly.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a measurement system for a knee joint gap and a measurement method for a knee joint gap. Background technique [0002] The knee joint is an important weight-bearing joint of the lower limbs, and its structure is also a relatively complex joint in the human body. During knee replacement surgery, correct ligament laxity and soft tissue balance are key indicators for the success of the operation. Therefore, during the operation, it is necessary to The gap between the femur and the tibia is measured by measuring the gap between the femur and the tibia under different knee joints in different degrees of extension and curvature. Usually, the doctor mainly relies on the doctor to manually feel the gap between the femur and the tibia during the operation. Due to the gap and relative force, the osteotomy cannot be performed accurately. Contents of the invention [000...
