Abstract

The invention provides a catheter intervention device. The catheter intervention device comprises a base, a feeding assembly, a lifting assembly and a yawing assembly, wherein the feeding assembly, the lifting assembly and the yawing assembly are located on the base, the lifting assembly is connected with the feeding assembly through a lifting plate, and the yawing assembly is located on one sideof the lifting assembly. According to the catheter intervention device, the interventional operations of feeding, spinning and yaw angle adjustment can be conducted on a catheter; and the device is compact in overall structure and high in precision.

Description

technical field [0001] The present invention relates to the technical field of catheter intervention, and more specifically, to a catheter intervention device. Background technique [0002] Cardiac interventional surgery is one of the most important options for the treatment of coronary heart disease. Minimally invasive vascular interventional surgery has become a recognized treatment for heart disease due to its small trauma, high safety, light patient pain, fast postoperative recovery, and few complications. important means of vascular disease. The current interventional cardiac surgery does not require thoracotomy. Doctors need to operate interventional devices such as guide wires and catheters in a physical way all the time, and directly operate the guide wires and catheters with their hands under the guidance of X-ray and other imaging methods. It is delivered from the patient's femoral artery (or radial artery) to the stenotic coronary artery lesion after percutaneous...
