Problems solved by technology

[0004] 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

[0024] Specific embodiments of the present invention, such as figure 1 and figure 2 As shown, a double-curved handle, including: a catheter (in this specification, the term catheter refers to including catheters and similar medical devices), in figure 1 As shown in , the catheter is generally divided into: an electrode 5, a distal end 4, a catheter body 1, and a control handle 2 (that is, the grasping part and the control part of the propulsion device), and the control handle 2 is used as a whole to control the pulling wire 6 and The relative position of the catheter body 1 controls the bending or deflection of the distal end 4 , and the wire 7 for transmitting electrical signals or energy passes through the rotating part 22 from the catheter body 1 and reaches the tail joint 8 of the control handle 2 .

[0025] The structural principle of the control handle of the catheter of the present invention is as follows: figure 2 and 3 shown. Among them, the gripping part 2 and ...

Abstract

The invention discloses a dual-bent handle, which comprises a holding part and an operating component arranged in the holding part and used for driving a traction wire to move, and is characterized in that the operating part comprises a rotating component; a rotating shaft of the rotating component is vertical to the length direction of the holding part; the rotating component is provided with a first fixing piece and a second fixing piece used for fixing the traction wire respectively; and the first fixing piece and the second fixing piece are distributed on both sides of the center line of the holding part. The device is operated flexibly, can be used for accurately controlling a tube body to arrive different focuses of infection, and is accordant with a human-machine engineering principle in design; a user can hold the holding part completely with the palm, so that in an operating process, fatigue on fingers and the palm are prevented; and moreover, the user can operate stably in the operating process.

Description

technical field [0001] The invention relates to a control handle of a medical catheter, in particular to a double-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, catheter handles of various structures are used. Chinese invention patent application 200810176905 discloses a control handle with a device propulsion mechanism. The handle controls the relative movement of the catheter and the steel wire by means of helical propulsion. [0004] Most of the prior art uses a propulsion mechanism with one-sided adjustment of the screw. This mechanism is likely to caus...
