Novel vascular intervention guide wire conveying mechanism

Abstract

The invention relates to a novel vascular intervention guide wire conveying mechanism which comprises a base, a guide wire catheter roller I and a guide wire catheter roller II. A guide wire catheter is arranged between the guide wire catheter roller I and the guide wire catheter roller II in a penetrating mode, and a guide wire catheter rotating motor I drives a lead screw I to rotate and drives a lead screw nut I to do linear motion. A guide wire catheter rotating motor II drives a lead screw II to rotate and drives a lead screw nut II to do linear motion, and the lead screw nut I and the lead screw nut II respectively drive a guide wire catheter roller I and a guide wire catheter roller II to do linear motion so as to drive a guide wire catheter to do rotating motion; the linear wire feeding motor I drives the guide wire catheter roller I to rotate through the driving gear I and the driven gear I. The linear wire feeding motor II drives the guide wire catheter roller II to rotate through the driving gear II and the driven gear II, and then the guide wire catheter is driven to do linear motion. Under the cooperative work of the two sets of lead screw transmission mechanisms, rotary motion and linear motion of a guide wire (catheter) are achieved at the same time.

Description

[technical field] [0001] The invention relates to the technical field of medical devices, in particular to a novel vascular intervention guide wire delivery mechanism. [Background technique] [0002] In the prior art, in the delivery device mechanism of the vascular interventional guide wire, the forward and backward movement and the screwing movement are realized separately, so if the user needs to realize the combined movement of the forward movement and the spinning movement at the same time, it cannot be realized. However, when a clinician delivers a guide wire or a catheter, it is often necessary to realize the functions of advancing and spinning at the same time. Therefore, it will be of great significance to provide a mechanism that can simultaneously realize the advancing and screwing movements of the guide wire. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide a new type of vascular ...
