Problems solved by technology
However, at present, although many structural forms of ablation catheters have been proposed in the industry, most of the traditional ablation catheters cannot conveniently and flexibly adjust the mutual position between electrodes; even if they have the adjustment function, the adjustment range is not controlled and cannot be adjusted accurately

Embodiment approach 1
[0048] Figure 1 to Figure 3 An ablation catheter according to a preferred embodiment of the present application is described. If a more detailed distinction is made, Figure 1 to Figure 3 It can also be divided into three different implementation modes below the first implementation mode.
[0049] Such as Figure 1 to Figure 3 In the illustrated embodiment of the present application, the ablation catheter may include a tubular member 10 , a main control shaft 11 and an ablation assembly A.
[0050] The tubular member 10 has an operating end (for connecting the control handle and the controller, not shown in the figure) and a working end 101 . The working end 101 will enter a predetermined position of the human body for subsequent operations. The tubular member 10 is in the shape of a thin tube and is flexible so as to allow winding and shuttling in the human body according to different paths; the inner diameter of the tubular member 10 is generally about 1-5 mm, preferably 1...

The present application discloses an ablation device and its ablation catheter. The ablation catheter includes: a tubular member, the tubular member is flexible and has an operating end and a working end; a main control shaft, the main control shaft is slidably arranged on the tubular member Inside: an ablation assembly, the ablation assembly is flexible and slidably disposed in the tubular member, the ablation assembly has an ablation element bearing part made of shape memory material, the ablation element bearing part carries a plurality of ablation elements, the ablation assembly Driven by the main control shaft, it can be retracted into the tubular member to maintain a linear extension state and can be protruded from the working end of the tubular member so that the ablation element bearing part presents a radially expanded portion. The ablation catheter includes: at least one auxiliary control shaft. , the auxiliary control shaft is slidably disposed in the tubular member, and the auxiliary control shaft is fixedly connected to the ablation component bearing part of the ablation assembly, so as to slide along the main control shaft driven by the auxiliary control shaft.
Description
technical field [0001] The present application relates to the field of ablation, and more specifically, relates to an ablation catheter for ablation of a tissue object to be treated and an ablation device including the ablation catheter. Background technique [0002] Ablation involves placing a catheter into the tissue object to be treated, and then using the catheter's electrodes to apply energy to the tissue, thereby selectively killing cells in a certain area. Ablation treatment has a wide range of indications, such as solid tumors, atrial fibrillation, etc. [0003] When ablation is used to treat atrial fibrillation, the end of the catheter is delivered to the target location in the heart through vascular puncture, and then the electrical discharge is ablated. The purpose of treatment is achieved by correcting the abnormal conduction path of cardiac electrical signals. [0004] An ablation device is a device for ablation treatment, and generally includes an electrode w...
