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" used here refers to the application of radiofrequency current with a frequency high to a certain value (>100kHz) to biological tissue, causing the movement of charged ions in the tissue to generate a thermal effect, and heating the tissue to a target temperature (eg 60-100°C), resulting in thermal damage to tissue or cell necrosis.
[0030] as attached figure 1 As shown, an electrode for radiofrequency ablation of esophageal reflux includes an electrode bundle 1, an electrode cap 2, an electrode seat 3, a central rod 4, a catheter 5, a handle 6, a knob 7, a cable 8, a plug 9, a water injection nozzle 10, and a water injection tube 11 and hose 12.
[0031] The electrode bundle 1 can be expanded into an olive shape, and there is a small section of non-insulating coating at the largest diameter of the olive shape, and other parts including the electrode cap 2, the electrode seat 3 and the catheter have an insulating layer;

An esophagus regurgitation radiofrequency ablation electrode comprises an electrode beam (1), an electrode cap (2), an electrode base (3), a center pull rod (4), a guide pipe (5), a handle (6), a rotary knob (7), a cable (8), a plug (9), a water injection nozzle (10), a water injection pipe (11) and a hose (12). The electrode beam (1) can be opened into an olive shape, a conducting region is arranged on the section, with the maximum diameter, of the olive, and an insulating layer is arranged at other parts of the esophagus regurgitation radiofrequency ablation electrode. The electrode beam (1) is made of conducing metal capillary tubes, the metal capillary tubes are divided into multiple groups, and at least one metal capillary tube in each group is used for cooling liquid to flow through. The electrode can conveniently and accurately conducts radiofrequency ablation treatment on the annular region of the esophagus and conducts cooling, as the electrode beam is of an olive structure, the cooling liquid can flows into the stomach easily, and the risk that the cooling liquid flows out of the esophagus to the pharyngeal and is sucked into the trachea when the sacculus is used is avoided.
Description
technical field [0001] The invention relates to a radio frequency ablation electrode for esophageal reflux, in particular to a radio frequency ablation electrode which can cooperate with an endoscope to treat esophageal reflux. Background technique [0002] Gastroesophageal reflux disease (GERD) refers to the general term for gastroesophageal reflux and esophageal mucosal injury diseases caused by excessive contact (or exposure) of the gastroesophageal lumen to gastric juice; A disease in which intestinal contents reflux into the esophagus causing 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 in clinical practice, while the latter is mainly seen after subtotal gastrectomy, gastrointestinal anastomosis, and esophagoenterostomy postoperative. The occurrence of gastroesophageal reflux and its complications is multifactorial, including defects in the ant...
