Description

technical field [0001] The invention relates to the field of medical devices, in particular to a human knee joint soft tissue pressure and track measurement system. Background technique [0002] Chinese patent (CN101884542B) discloses a pressure balance measurement system for artificial knee replacement, which includes a pressure acquisition device and a signal receiving and display device; the pressure acquisition device is used to place it on the patient's knee joint to obtain pressure during the doctor's operation signal, and send the pressure signal to the signal receiving display device; the pressure acquisition device includes a closed shell, and an upper force plane, a lower support plane, a sensor array and a circuit board arranged in the closed shell, and the sensor array is located on the circuit board Above, the sensor array is composed of more than three sensors, and the circuit board in the middle of the three or more sensors has a cavity. The combination with ...

AI Technical Summary

Problems solved by technology

[0005] 1) The measurement of the above pressure value mainly uses sensors, and each sensor can only measure the pressure value of the corresponding point

There are also limitations on the size of the knee prosthesis and the number of sensors, so the measured pressure area is extremely insufficient relative to the knee prosthesis and cannot cover all contact areas;

[0006] 2) The number of the above-mentioned sensors is more than three, and there is interference between the sensors, which makes the measurement process more difficult;
