Guide wire delivering and rotary twisting device of minimally-invasive vascular interventional surgical robot

Abstract

The invention belongs to the technical field of medical equipment and particularly relates to a guide wire delivering and rotary twisting device of a minimally-invasive vascular interventional surgical robot. The guide wire delivering and rotary twisting device comprises a bottom plate, a moving assembly, a rotary twisting assembly, a clamping assembly, a fixing assembly and a Y valve fine-adjustment assembly, wherein the rotary twisting assembly comprises a rotating support, a rotary twisting motor, a driving friction wheel, a driven friction wheel and a rotary twisting main shaft; and the Y valve fine-adjustment assembly comprises a fixed frame, a movable frame, a Y valve and a hand wheel. Through the moving assembly, the rotary twisting assembly, the clamping assembly, the fixing assembly and the Y valve fine-adjustment assembly, delivery, rotary twisting, clamping, fixing and fine adjustment of a guide wire are achieved, repeated continuous delivery work of the guide wire can be achieved, rotary twisting action can be conducted on the guide wire according to actual conditions in a delivery process of the guide wire, delivery movement and rotary twisting movement of the guide wire can be decoupled, the guide wire can accurately enter a bifurcated blood vessel and reach a correct lesion position, and the delivery precision of the guide wire is improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a robot guidewire delivery twisting device for minimally invasive vascular interventional surgery. Background technique [0002] According to the statistics of the World Health Organization, cardiovascular and cerebrovascular diseases have become the number one killer of human death, 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. Minimally invasive vascular interventional surgery is currently a major treatment method for cardiovascular and cerebrovascular diseases. In traditional vascular interventional surgery, doctors use angiography machine to navigate to observe the patient's blood vessels, and precisely manipulate the guide wire from the punc...
