Catheter/wire rotating mechanism and propulsion device for minimally invasive vascular interventional surgery robot

Abstract

The invention relates to the technical field of medical equipment, in particular to a catheter / guide rotating mechanism and a propulsion device for a minimally invasive vascular interventional surgeryrobot. The propulsion device includes a rotating mechanism, a clamping mechanism, a fixing mechanism and a moving mechanism. The rotating mechanism includes a rotating motor, an active pulley, a tensioning pulley, a limiting eccentric wheel and five roller pin bearing components. The clamping mechanism includes a clamping rotating shaft, a clamping claw, a clamping claw sleeve and a clamping spring; the fixing mechanism includes a fixing finger guide rail, a fixing finger slide block, a fixing finger sliding base, a motor friction wheel guide base, a spring guide rod, a fixing finger motor, afixing finger eccentric wheel, a movable rubber block and a fixed rubber block; the fixing finger eccentric wheel drives the fixing finger sliding base to move so as to make the movable rubber blockand the fixed rubber block clamped or separated; the moving mechanism drives the rotating mechanism and the clamping mechanism to move close to or far from the fixing mechanism. According to the catheter / wire rotating mechanism and the propulsion device, the clamping body component of the clamping mechanism is convenient to disassemble and disinfect and the clamping claw does not slip.

Description

technical field [0001] The invention relates to a catheter / guide wire rotating mechanism and a propulsion device of a minimally invasive vascular interventional robot, belonging 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. Compared with traditional heart surgery, minimally invasive vascular interventional surgery has great advantages. The human heart is protected by the surrounding thorax. Traditional heart surgery requires doctors to saw through the sternum for surgery, and most of the thoracotomy wounds exceed 20 cm , It will cause additional damage to the patient's body, and the postoperative re...
