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

[0030] Specific embodiments of the present invention, such as figure 1 , figure 2 and image 3 As shown, a single curved handle includes:

[0031] 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, ring electrode 2, catheter body 3, gripping part and manipulation part, the gripping part and manipulation part are used to control the relative position of the pulling wire and the catheter body , so as to control the bending or deflection of the catheter part where the distal electrode 1 and the ring electrode 2 are located.

[0032] The structural principle of the single curved handle of the catheter of the present invention is as follows: figure 2 and image 3 shown. Wherein, the gripping part 7 and the manipulation part 5 slidably installed in the gripping part, wherein the part of the manipulation part 5 is l...

Abstract

The invention discloses a single bending handle which comprises a grabbing part and a control part glidingly mounted in the grabbing part, wherein a limit part for limiting the sliding range of the control part is arranged in the grabbing part; a catheter body is connected with the control part; and a traction fiber is connected with the grabbing part. The single bending handle is characterized in that the tail end of the control part is located in the grabbing part, and a device for adjusting the diameter of the tail end is arranged at the tail end of the control part. The single bending handle is designed in accordance with the man-machine engineering principle, a palm can grasp the grabbing part completely, so that during an operation process, fingers and the palm are not prone to fatigue, and the operation is stable during an operation process of a user.

Description

technical field [0001] The invention relates to a medical catheter device, in particular to a single-curved handle 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 helical segment at the di...
