Abstract

The invention discloses a bone joint tension balancer based on a Zigbee communication protocol. The bone joint balancer comprises a Zigbee wireless receiving circuit, an upper computer information management system, a bone joint balancer entity structure, and a pressure sensor array, an analog / digital conversion circuit and a Zigbee wireless transmitting circuit which are arranged on the bone joint balancer entity structure; each sensor of the middle flexible pressure sensor array is connected with the digital conversion circuit; the analog / digital conversion circuit is connected with the Zigbee wireless transmitting circuit; the Zigbee wireless transmitting circuit is communicated with the Zigbee wireless receiving circuit; and the Zigbee wireless receiving circuit is connected with the upper computer information management system. According to the invention, data informatization in the bone joint operation process is realized.

Description

technical field [0001] The invention belongs to the field of intelligent medical equipment, in particular to a bone joint tension balancer based on the zigbee communication protocol. Background technique [0002] With the continuous advancement of modern medical care, many instruments are being updated. However, the balancer used in bone and joint surgery is still a relatively traditional mechanical component, which cannot complete real-time data collection. However, in many cases, the doctor It is necessary to know the pressure changes in the bone joints, so as to judge the state of the patient during the operation. Therefore, the traditional purely mechanical balancer can no longer meet the needs of doctors for bone and joint surgery. Contents of the invention [0003] The object of the present invention is to provide a bone joint tension balancer based on the zigbee communication protocol. [0004] The technical solution to realize the object of the present invention ...
