Double-control bent electrophysiological catheter

Abstract

A double-control bent electrophysiological catheter comprises a catheter body, a first guiding wire, a second guiding wire, a handle body, a push-and-pull control key and a rotary control key, wherein the first guiding wire and the second guiding wire are arranged in the catheter body; the handle body is connected with the catheter body; the push-and-pull control key and the rotary control key are arranged on the handle body and respectively control the first guiding wire and the second guiding wire; and two or more than two bent sections are arranged at a distal end of the catheter body. The double-control bent electrophysiological catheter is characterized in that the push-and-pull control key and the rotary control key are arranged on the handle body in a matched manner and synchronously slide along the length direction; and the rotary control key can rotate relative to the push-and-pull control key. The push-and-pull control key and the rotary control key of the double-control bent electrophysiological catheter synchronously slide, and can be controlled by a user with a single hand. Because the push-and-pull control key and the rotary control key can be directly pushed by the user with the single hand, the double-control bent electrophysiological catheter is convenient to control and use.

Description

technical field [0001] The invention relates to a medical catheter, in particular to a conveniently operated double-control bending electrophysiological catheter. Background technique [0002] Catheter tubing is usually made of flexible, biocompatible materials, such as plastics, including polyethylene, polyester, or polyamide. Due to the complex physiological structure of the human body, a handle with superior manipulability is required to control the catheter, and it is extremely challenging to control the catheter to accurately reach different lesions. [0003] In order to solve this problem, people have adopted catheters and their control handles of various structures, such as a dual-control catheter and control handle disclosed in US Patent Application US2008039918A1, the distal end of the catheter can be bent or adjusted. Diameter, in which bending and adjusting the diameter of the helical part are achieved by manipulating the two control keys on the handle respective...

Problems solved by technology

Due to the complex physiological structure of the human body, a handle with superior manipulability is required to control the catheter, and it is extremely challenging to control the catheter to accurately reach different lesions

[0003] In order to solve this problem, people have adopted catheters and their control handles of various structures, such as a dual-control catheter and control handle disclosed in US Patent Application US2008039918A1, the distal end of the catheter can be bent or adjusted. Diameter, in which bending and adjusting the diameter of the helical part are achieved by manipulating the two control keys on the handle respectively. During the actual operation, the user needs to adjust separately, which is inconvenient to directly realize the control and operation of the catheter with one hand

[0004] The control keys for controlling the guide wires on the existing catheter control handle with dual guide wires inside are usually set separately. During use, the fingers need to be continuously moved in a large range to control different operation keys, which makes it inconvenient to use and easy to use with fingers. fatigue
