Embodiment Construction

[0032] Specific embodiments of the present invention, such as figure 1 with figure 2 As shown, a perfusion electrophysiological catheter with controllable bidirectional deflection includes: catheter (in this specification, the term catheter refers to 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 .

[0033] The structural principle of the control handle of the catheter of the present invention is as follows: figure 2 wi...

Abstract

The invention discloses a controllable bilateral-deflection perfusion electrophysiologic conduit which comprises at least one section of spirally wound electrode arranged on the conduit body, a grasp part, and a control component mounted in the grasp part and used for driving traction fibers to move. The perfusion electrophysiologic conduit is characterized in that the spirally wound electrode is a hollow electrode tube, a plurality of through holes are formed in the surface of the electrode tube, and the inside of the electrode tube is communicated with an infusion tube for conveying a perfusate; the control component comprises a rotary component whose rotating shaft is perpendicular to the length direction of the grasp part, and a first fixing part and a second fixing part used for fixing the traction fibers respectively are arranged on the rotary component and distributed on two sides of the center line of the grasp part. The electrophysiologic electrode capable of spraying a liquid can improve the perfusion effect effectively, and can improve the safety and the reliability of an ablation catheter; and the device is flexible to control, and can control the conduit body to reach different lesion locations accurately.

Description

technical field [0001] The invention relates to a control handle of a medical catheter, in particular to a controllable bidirectional deflection perfusion electrophysiological catheter for the medical catheter. Background technique [0002] In the existing cardiac ablation surgery, the ablation catheter is usually sent into the heart, and the electrode at the end of the catheter forms a circuit with the opposite electrode on the patient's back, and heat is applied to damage or modify the myocardial tissue where arrhythmia occurs, causing it to dehydrate and solidify. loss of electrical conductivity. This treatment is mainly used for electrophysiological ablation of tachyarrhythmias such as paroxysmal supraventricular tachycardia, atrial tachycardia, atrial flutter, and paroxysmal ventricular tachycardia. During ablation, in order to achieve a deeper ablation depth, higher ablation energy will be used clinically, which will often cause local overheating of myocardial tissue ...
