Problems solved by technology

[0008] The radiofrequency ablation electrode needle currently used clinically uses a balloon to insert the electrode needle into the tissue to be treated by radiofrequency ablation. During the treatment, the esophagus will be blocked, and it will be cooled by flushing water. The cooling water in the esophagus may flow to the pharynx. Outflow, there is a risk of being sucked into the patient's trachea

Embodiment Construction

[0029] The term "radiofrequency ablation" as used herein refers to the application of radiofrequency currents at frequencies up to a certain value (>100 kHz) to living tissue, causing the movement of charged ions within the tissue to produce a thermal effect that heats the tissue to a target temperature (60 kHz). -100°C), resulting in thermal damage to tissue or cell necrosis.

[0030] as attached figure 1 As shown, an esophageal reflux radiofrequency ablation electrode includes an electrode bundle 1, an electrode cap 2, an electrode seat 3, a central pull rod 4, a catheter 5, a handle 6, a cable 7, a plug 8, a dial 10 and a central metal tube 11.

[0031] The electrode bundle 1 can be expanded into a boat shape, and there is a small section without insulating coating at the maximum diameter of the boat shape, and the other parts including the electrode cap 2, the electrode seat 3 and the catheter have insulating layers;

[0032] The electrode bundle 1 is made of a group of c...

Abstract

The invention provides an esophageal reflux radio frequency ablation electrode. The esophageal reflux radio frequency ablation electrode comprises an electrode bundle (1), an electrode cap (2), an electrode seat (3), a central pull rod (4), a guide pipe (5) and a handle (6). The electrode bundle (1) can be expanded to form a boat shape; a conducting region is arranged at a part with the greatest diameter of a section of the boat shape; and insulating layers are arranged at other parts of the esophageal reflux radio frequency ablation electrode. The electrode bundle (1) is composed of conductive metal capillary tubes; the metal capillary tubes are divided into a plurality of groups; and cooling liquid flows through at least one metal capillary tube in each group. The electrode provided by the invention can be used for conveniently and accurately implementing radio frequency ablation treatment on an esophageal annular region and implementing cooling.

Description

technical field [0001] The invention relates to a radiofrequency ablation electrode for esophageal reflux, in particular to a radiofrequency ablation electrode that can cooperate with an endoscope to treat esophageal reflux. Background technique [0002] Gastroesophageal reflux disease (GERD) is a general term for gastroesophageal reflux and esophageal mucosal damage caused by excessive exposure (or exposure) to gastric juice in the gastroesophageal cavity; A disease in which reflux of intestinal contents into the esophagus causes clinical symptoms and / or inflammation of the esophagus. Reflux is mainly gastric acid, pepsin, duodenal juice, bile acid, pancreatic juice, etc. The former is more common clinically, while the latter is mainly seen after subtotal gastrectomy, after gastrointestinal anastomosis, and esophagoenteric anastomosis. postoperative. The occurrence of gastroesophageal reflux and its complications is multi-factorial, including the defects of the anti-reflu...
