Description

Technical Field

[0001] The utility model relates to the field of high-voltage pulse ablation electrodes, and more specifically, to a respiratory tract high-voltage pulse ablation electrode device with a cage-type structure. Background Art

[0002] High-voltage pulse ablation is a new and effective ablation treatment method. It uses pulsed electric fields as an ablation treatment method. It applies extremely high electric field energy in a very short time, forming irreversible electroporation on the plasma membrane, causing cell death. It can overcome many problems caused by conventional thermal ablation effects.

[0003] After searching, the existing patent (Announcement No.: CN219921203U) discloses a visualized high-voltage pulse ablation electrode. The ablation catheter of a common ablation electrode is limited by the size of the endoscope. The electrode is small and difficult to process and the cost is high. It also requires other visual medical equipment to work together, and the operation requirements are high. To this end, the utility model provides a visualized high-voltage pulse ablation electrode, including an ablation catheter and a number of ablation electrodes arranged thereon. The ablation catheter is provided with a bendable tube section at the front of the distal end, and the bending is controlled by a pull wire passed through the ablation catheter. The ablation electrodes are connected to an external high-voltage pulse generator through an independent electrode wire passed through the ablation catheter. The ablation catheter is provided with a lens module at the front end. The lens module includes a connected lens and a lens wire, and the lens wire is connected to an external display. No external visual equipment is required during operation. The built-in lens module is used to observe and guide the ablation into the natural cavity of the human body. The electrode has a relaxed outer size, is easier to manufacture, has more stable quality, and is more convenient to operate.

[0004] When using the electrodes in existing respiratory high-pressure pulse ablation electrode devices with a bronchoscope for high-pressure pulse ablation, only the mesh closer to the bronchoscope can be observed, while the mesh farther from the bronchoscope cannot be seen, resulting in low treatment accuracy and certain limitations in its use. Furthermore, the aforementioned patent documents do not propose relevant solutions to address the above issues.

[0005] Therefore, in order to solve the above problems, a respiratory tract high-voltage pulse ablation electrode device with a cage structure is proposed. Utility Model Content
