Abstract

The invention discloses a guide wire/catheter delivery device for vascular intervention and a using method of the guide wire/catheter delivery device and a vascular intervention surgical robot. The delivery device comprises a clamping assembly used for clamping a guide wire/catheter, and a driving part, wherein the clamping assembly comprises a clamping base, one or more driving wheels and one or more driven wheels, the driving wheels and the driven wheels are rotationally mounted on the clamping base, and are symmetrically arranged on the two sides of the guide wire/catheter; the driving part comprises a wire feeding and retreating driving unit and a wire rotating driving unit, the wire feeding and retreating driving unit is connected with the driving wheels and drives the driving wheels to rotate, and the driving wheels rotate to drive the guide wire/catheter to move in the axial direction; and the wire rotating driving unit is connected with the clamping base and drives the clamping base to rotate in the axial direction of the guide wire/catheter, and then the guide wire/catheter is driven to rotate. The guide wire/catheter rotates around a shaft and axially moves independently or rotates around the shaft and axially moves synchronously in an automatic mode, guide wire propelling accuracy and precision are improved, and therefore the operation safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a guide wire / catheter delivery device for vascular intervention and a vascular interventional surgery robot. Background technique [0002] Vascular interventional surgery is a method in which doctors, under the guidance of subtractive angiography (DSA) equipment, manipulate interventional instruments to move in human blood vessels, and finally accurately reach the lesion and perform treatment. Common interventional devices include venous catheters, guide wires, filters, and spring emboli. Vascular interventional surgery has become an important means of treating cardiovascular diseases. Compared with traditional surgery, it has the characteristics of small incision, fast recovery and good effect. [0003] At present, the traditional operation method of vascular interventional surgery is that the doctor manually sends the catheter and guide wire into the patien...
