Problems solved by technology

Most of the existing technologies use a propulsion mechanism with one-sided adjustment of the screw. This mechanism is likely to cause imbalance in the control of the propulsion device, and most of them are similar to or follow the foreign technology, and the control handle will allow the operator to operate for a certain period of time, which will easily lead to fatigue.

Embodiment Construction

[0031] Specific embodiments of the present invention, such as figure 1 , figure 2 and image 3 As shown, a steerable electrophysiological catheter includes:

[0032] In this specification, the term catheter is meant to include (but not be limited to) catheters and similar medical devices. exist figure 1 As shown in , the catheter is generally divided into: distal electrode 1, wire-wound electrode or ring electrode 2, catheter tube body 3, gripping part and manipulation part, the gripping part and manipulation part are used to control the traction wire and the catheter tube The relative position of the body, thereby controlling the bending or deflection of the catheter part where the distal electrode 1 and the ring electrode 2 are located.

[0033] The structural principle of the controllable electrophysiological catheter of the catheter of the present invention is as follows: figure 2 and image 3 shown. Wherein, a combination of a wire-wound electrode and a ring elec...

Abstract

The invention discloses controllable electrophysiologic conduit which comprises a grasp part and a control component slidably mounted in the grasp part, wherein a limit component for limiting the sliding range of the control component is arranged in the grasp part; a conduit body is connected with the control component, and a traction fiber is connected with the grasp component. The controllable electrophysiologic conduit is characterized in that the tail end of the control component is located in the grasp part, and a device for adjusting the diameter of the tail end is arranged at the tail end of the control component. The design of the device accords with the man-machine engineering principle, a palm can hold the grasp part completely, fingers and palms are not prone to fatigue in an operation process, and the operation is smooth during the operation process by a user.

Description

technical field [0001] The invention relates to a medical catheter device, in particular to a controllable electrophysiological catheter for a medical 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 structure of the heart, 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 of the heart. [0003] In order to solve this problem, catheters of various structures are used. Chinese invention patent application 200810176905 discloses a control handle with a device propulsion mechanism, which controls the relative movement of the catheter and the steel wire in a helical propulsion manner. In an improved example, Chinese Patent No. 200680030272.X discloses a structure that controls the contraction and expansion of the hel...
