Tail end clamping device for robot surgery

Abstract

The invention provides a tail end clamping device for robotic surgery. The tail end clamping device comprises: a locking main body; a mechanical arm tail end clamping assembly, which is assembled on the locking main body and is matched with the locking main body to clamp the tail end of an mechanical arm; and an ultrasonic knife clamping assembly, which is assembled on the locking main body and is matched with the locking main body to clamp an ultrasonic knife. According to the tail end clamping device for the robot surgery, the ultrasonic knife only needs to be clamped between the ultrasonic knife clamping assembly and the locking main body, the mechanical arm tail end clamping assembly and the locking main body are matched to be clamped at the tail end of the mechanical arm, and the mechanical arm is controlled to conduct an operation, so an operator does not need to hold the ultrasonic knife to conduct the operation, the problem that the operator indirectly feels fatigue when holding the ultrasonic knife manually for an operation for a long time in the prior art is solved, the fatigue feeling of a doctor in the operation is relieved, and operation accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an end clamping device for robotic surgery. Background technique [0002] In the field of minimally invasive surgery, it is often necessary for the doctor to hold an ultrasonic knife to cut, strip and stop bleeding. The operator manually holds the ultrasonic knife to perform the operation, which usually takes more than 3 hours, and for some complicated surgical operations, it can even reach 10 hours. . When the ultrasonic scalpel is used, due to its vibration cutting working characteristics, even if the hard cortical bone is cut, the highest resistance is usually below 10N, and the resistance of cancellous bone is only between 1-4N, which is very dependent on the doctor's operation status. In long-term surgery, the operator stands for a long time and carries out the operation with the ultrasonic knife, which is prone to fatigue, loses the ability to judge the accuracy ...

AI Technical Summary

Problems solved by technology

Long-term operation, the operator stands for a long time and carries out the operation with the ultrasonic knife, which is prone to fatigue, loses the ability to judge the accuracy of the force, and easily affects the quality of the final operation
