Description

Positioning and guiding device for vascular intervention Technical Field The invention relates to the technical field of medical appliances, in particular to a vascular intervention positioning and guiding device. Background Vascular intervention is a percutaneous puncture, uses the apparatus such as the guide wire, conduit, etc. to carry on the minimally invasive technology of the operation treatment in the blood vessel cavity, apply to coronary heart disease, cerebrovascular disease and peripheral vascular disease treatment extensively, in the course of operation, doctor need to push guide wire and conduit to the target lesion site accurately, such as the stenosis or aneurysm cavity; the existing vascular intervention positioning guide device is controlled by a doctor through a handheld instrument to control a guide wire and a catheter, has high requirements on the technology of the doctor, is easy to twist or deviate relative to the guide wire when the catheter is pushed in a tortuous vascular section, so that the tip of the catheter scratches the inner wall of a blood vessel, and the risks of vasospasm, interlayer and even perforation are increased. Disclosure of Invention The invention aims to provide a vascular intervention positioning guide device for solving the problems in the background technology.
