Abstract

The invention discloses a polyp removing machine and a polyp removing method thereof. The polyp removing machine comprises an electrocoagulation head assembly comprising an electrocoagulation head, an electrocogulation conduit and an electrode; the electrocoagulation head is fixedly mounted at the head of the electrocoagulation conduit; the electrode is electrically connected with the electrocoagulation head; the electrocoagulation assembly also comprises an outer tube and an injection needle assembly; a channel hole is formed in the outer tube; the head end part of the channel hole is a polyp positioning cavity; the injection needle assembly comprises an injection needle and a hollow injection needle conduit; the injection needle is fixedly inserted in the head of the injection needle conduit; the electrocoagulation conduit is inserted in the channel hole of the outer tube and can axially move relative to the outer tube; the injection needle conduit is inserted in the electrocoagulation conduit and can axially move relative to the electrocoagulation conduit. The polyp removing machine and the polyp removing method thereof can improve the positioning precision of polyp, so the phenomenon of scorching and perforation of stomach and intestine walls caused by difficult positioning due to the peristalsis of the stomach and intestines is avoided.

Description

technical field [0001] The invention relates to an instrument for removing polyps and a method for removing polyps, belonging to the technical field of medical devices. Background technique [0002] At present, gastrointestinal polyps are a common disease in gastroenterology. For directly smaller polyps, the conventional method is to use electrocoagulation to remove them. Commonly used instruments include thermal biopsy forceps, spherical electrocoagulation tips, etc. However, due to the peristalsis of the gastrointestinal tract, it is difficult to accurately position the electrocoagulation equipment, and because the intestinal wall is very thin, it is easy to burn and perforate, resulting in medical accidents. Therefore, there is an urgent clinical need to study a new surgical method and related instruments to replace the existing methods and instruments. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the de...
