Problems solved by technology

However, the mechanical structure of this technology has only two degrees of freedom. The 3D mouse is only used for rough positioning, and no control method is mentioned at all. In addition, the 3D mouse can realize simultaneous control of movement and rotation, which increases the confusion of movement and rotation. Risk of manipulation, prone to major accidents during surgery

Abstract

The invention provides a manual operating device for a bone surgery assisted robot, belonging to the technical field of medical appliances. The device is arranged on the tail end of a mechanical arm, and comprises a three-freedom operating rod, a mode selection switch and a redundancy gesture control switch, wherein the three-freedom operating rod, the mode selection switch and the redundancy gesture control switch are respectively connected with a robot controller through a signal cable; a signal processor comprises a digital IO module, an A / D conversion module and a calculation module; the A / D conversion module converts a voltage analogue signal from a potentiometer in the operating rod into a digital signal and inputs to the calculation module; the digital IO module inputs the state information of the mode selection switch and the redundancy gesture control switch into the calculation module; the calculation module transmits a control instruction to the robot controller through a serial bus and the robot controller realizes the robot action. The device can enable the operators to control position and gesture of the executor at the tail end of a seven-freedom robot.

Description

technical field [0001] The invention relates to a device in the technical field of robots, in particular to a manual manipulation device for an orthopedic surgery auxiliary robot. Background technique [0002] The main goal of orthopedic surgery assisting robot is to assist physicians to complete specific fine operations in orthopedic surgery. The robot can perform the following functions during surgery: osteotomy cutting, grinding and drilling, clamping and fixing, etc. Robots have great advantages in completing these operations. On the one hand, the movements are relatively simple, and robots can be competent; on the other hand, these operations require high precision and stability, and the positioning of manipulators is more accurate, stable and powerful than humans. During the use of the robot, the robot mainly completes the actions planned before the operation under the guidance of the navigation device, but the doctor also needs to adjust and confirm the position and ...
