Abstract

The invention provides a catheter delivery method, a catheter is fixedly connected to a catheter operator, and a controller controls the catheter operator to move; a guide wire is arranged on a guidewire operator and is arranged in the catheter in a penetrating manner; the guide wire operator can clamp or loosen the guide wire, and the controller controls the guide wire operator to move; and thecontroller limits the distance between the catheter operator and the guide wire operator for delivery of the catheter and maintains the guide wire between the catheter operator and the guide wire operator unbent. According to the catheter delivery method provided by the invention, no guide wire anti-bending device is arranged between a catheter holder and a guide wire holder, and the catheter is delivered by virtue of the toughness of the guide wire; and the distance between the catheter holder and the guide wire holder is limited within a certain range, the catheter operator and the guide wire operator cooperate with each other to achieve catheter delivery, and meanwhile it is guaranteed that the guide wire is not bent in the delivery process.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a catheter delivery method. Background technique [0002] Endovascular technology has become the basic means of vascular treatment, and most of the vascular reconstruction operations currently performed require the help of this technology. The operation of guide wire and catheter is the core content of endovascular technology, which determines the quality of operation. At present, clinical doctors use digital silhouette angiography (DSA) to manually complete the positioning operation of the guide wire and catheter in the patient's blood vessel. Conventional passive guide wires, guiding catheters, and balloon catheters are the basic instruments used in surgery. The use of robotic devices for positioning operations of catheters and guide wires is conducive to improving the accuracy of positioning operations, reducing doctor fatigue, and improving surgical qual...
