Double pole high-frequency electric scalpel capable of achieving two-channel liquid injection

Abstract

The invention provides a double pole high-frequency electric scalpel capable of achieving two-channel liquid injection. The double pole high-frequency electric scalpel comprises an electrode part, a main body part and an operation part. The electrode part comprises an active electrode, an insulation piece and a noble electrode; the active electrode has a hollow tubular part and can cut a target pathological tissue after being connected to a power source; the main body part comprises a protection pipe, an outer insulation pipe, a spiral piece coated with an insulation coating, a connection piece, a sealing piece and the like. The spiral piece coated with the insulation coating comprises a conductive spiral piece and the insulation coating which coates the surface of the spiral piece; the operation part comprises a locating structure, a slide block, a core rod, a connection sheath, an infusion pipe and a connection cable, 6% Luer tapers are connected to both the locating structure and the infusion pipe, fluid can flow out from the hollow tubular part of the active electrode, the lower layer of mucosa is injected so that mucosa tissues can swell, and a bleeding part can be cleaned. The fluid can also pass through a gap between the active electrode and the insulation piece, and thus the tissues attached to the active electrode and the insulation piece and the bleeding part can be cleaned.

Description

technical field [0001] The invention relates to a medical bipolar high-frequency electric knife in the field of medical equipment, in particular to a bipolar high-frequency electric knife that integrates the functions of cutting marking, injection and flushing and is used for endoscopes and can inject liquid through two channels. . technical background [0002] Endoscopic technology has been born for more than 50 years. It has gone through the stages from disease diagnosis to disease treatment. It has been very effective and reliable for the treatment of some digestive diseases, and has even become the first choice for treatment. In recent years, with the development of endoscopic technology, endoscopic tissue biopsy, endoscopic mucosal resection (Endoscopic mucosal resection, EMR) and endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) have been widely used. The treatment of tract bleeding, polypectomy and early cancer is gradually becoming the first c...
