Clamping, rotating and conveying mechanical hand for guide wire catheter operation in intravascular intervention surgery

Abstract

The invention provides a clamping, rotating and conveying mechanical hand for guide wire catheter operation in intravascular intervention surgery. The clamping, rotating and conveying mechanical hand comprises a clamping mechanism used for automatically centering and clamping a guide wire catheter, a wire rotating mechanism used for driving the clamping mechanism to rotate around the axis of the guide wire catheter and a pushing mechanism used for straightly pushing and pulling the guide wire catheter, the clamping mechanism is fastened to a rotating supporting ring of the wire rotating mechanism, and the wire rotating mechanism is arranged on a sliding block of the pushing mechanism. The clamping, rotating and conveying mechanical hand has the following advantages of being compact and stable in structure, high in centering performance, easy to assemble, disassemble and disinfect and capable of clamping, rotating, pushing and pulling the guide wire catheter to achieve single-hand operation on the guide wire catheter by a doctor; the influence on surgery quality due to hand tremble of the doctor and uneven support releasing force during the surgery is eliminated; the doctor is prevented from being damaged by rays, and the body of the doctor is protected.

Description

technical field [0001] The invention relates to the medical field, in particular to a clip-and-transfer manipulator for guide wire catheter operation in vascular interventional operations. Background technique [0002] Vascular interventional operations require doctors to complete them under radiation monitoring. Doctors suffer cumulative radiation damage and their health is seriously threatened. During interventional surgery, inherent defects such as doctor's hand trembling and uneven release force of the stent will affect the effect of interventional treatment to varying degrees. Research on the dexterous auxiliary device that can operate the guide wire catheter, so that the doctor can protect the personal health of the interventional medical staff in the environment away from the radiation, and use the vibration isolation and precise movement characteristics of the mechanical device to improve the effect of the interventional therapy. The inevitable demand for the develo...

Problems solved by technology

Its disadvantage is that it can only complete the feeding and rotation of the guide wire catheter, and cannot realize more complex surgical actions, such as the cooperation of the tube wire, and is not compatible with most existing guide wire catheters, and even requires a customized guide wire catheter
