Double Control Bend Handle

Abstract

The invention discloses a double-control bent handle. The double-control bent handle comprises a handle body, a push-and-pull control key and a rotary control key. The push-and-pull control key and the rotary control key respectively control a first guiding wire and a second guiding wire. The double-control bent handle 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 on the handle body 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 handle 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 handle is convenient to control and use.

Description

technical field [0001] The invention relates to a control handle of a medical catheter, in particular to a conveniently operated double-control bending handle. 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 catheter 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 the diameter of the helical part can be adjusted, wherein Bending and adjusting the diameter of the helical part are achieved by manipulating the two control keys on the handle res...

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 catheter 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 the diameter of the helical part can be adjusted, wherein Bending and adjusting the diameter of the helical part are achieved by manipulating the two control keys on the handle respectively. In the actual operation process, 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
