Tube and wire feeding device for intravascular intervention surgical robot

Abstract

The invention discloses a tube and wire feeding device for an intravascular intervention surgical robot, and belongs to the field of medical devices. The tube and wire feeding device belongs to an end effector of the intravascular intervention surgical robot, and mainly comprises an execution part and a driving part; the driving part and the execution part can be quickly connected and separated through a lock catch, so that the used execution part after an operation is completed is separated, cleaned and sterilized, and is replaced by the sterilized execution part for the next operation. The device also can be divided into three modules, namely a clamping finger, a moving finger and a rotating finger; each module comprises an execution part and a driving part; the clamping finger is arranged at the front end of the execution part and has the gripping and fixing function; the moving finger clamps a catheter (guide wire) to move forwards (backwards) in the process of the operation, so that the catheter (guide wire) moves forwards (backwards) in a blood vessel; and the rotating finger can clamp the catheter (guide wire) to rotate positively or reversely, so that the front end of the catheter (guide wire) changes the direction so as to enter a bifurcated blood vessel.

Description

technical field [0001] The invention discloses a tube-feeding and wire-feeding device for a minimally invasive vascular interventional surgery robot, which belongs to the field of medical equipment. Background technique [0002] Cardiovascular and cerebrovascular diseases are currently the number one killer facing human beings, seriously threatening people's lives, health and living standards. With the development of social science and technology and the continuous improvement of people's living standards, people have paid more attention to cardiovascular and cerebrovascular diseases. At present, the treatment of cardiovascular and cerebrovascular diseases mainly relies on surgery, and minimally invasive vascular interventional surgery has great advantages compared with traditional cardiac surgery. The human heart is protected by the surrounding thorax. Traditional heart surgery requires the doctor to saw the sternum for surgery, and the thoracotomy wound is as large as 20 ...

AI Technical Summary

Problems solved by technology

However, due to the fixed bending radius of the front end of the existing catheter and the characteristics of long and narrow bends, irregularities, and many branches in the blood vessels in the human body, this method is highly skilled and risky, and requires a long training time for specialists. Factors such as long operation time, doctor fatigue and unstable manual operation will directly affect the quality of operation and thus the quality of life of patients
