Lower limb side force line measurement device and method

Abstract

The invention reveals a lower limb side force line measurement device. The lower limb side force line measurement device includes a protective housing, a circuit board, a switch, a power supply, and a steel nail; the steel nail is movably arranged on the protective housing; the circuit board and the power supply are arranged in the protective housing; the switch is arranged outside of the protective housing; the circuit board is welded with a microprocessor, an accelerometer, a gyroscope, a magnetometer, and a Bluetooth transmission module, wherein the accelerometer, the gyroscope and the magnetometer are electrically connected to the microprocessor, and the micro processor is electrically connected to the Bluetooth transmission module; and the accelerometer, the gyroscope and the magnetometer measure corresponding data, the microprocessor performs algorithm treatment on the data, and a human body lower limb side force line is display in an external display device through the Bluetooth transmission module.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for measuring lateral force lines of lower limbs. Background technique [0002] In the process of knee replacement, the lateral force line of the lower limb is a concern of orthopedic surgeons, and the placement of prostheses according to the lateral force line of the lower limb is the key to the success of the operation. At present, doctors often rely on personal experience to judge the connection position of artificial joints, which may cause improper replacement or even failure, which will lead to pain, limited joint movement, looseness, wear and joint instability, and bring serious serious problems to patients and their families. Influence. For knee replacement surgery, if you want to improve the success rate and make the joint replacement more accurate, the key is to find the position of the force line on the side of the human tibia. [0003] At...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no special equipment or instrument to measure the lateral force line of the lower limbs, and then assist in the precise replacement of joints. However, based on experience and subjective judgments, there are large uncertainties and artificial parallax, which are prone to errors and bring pain to patients. pain, which requires an efficient device to provide judgment basis for surgery
