Abstract

The invention provides a high-frequency electric knife for endoscope, which comprises a handle part and a flat knife head. tube; the handle part includes a thumb ring, a handle, a sliding handle, a 6% luer connector, an electrode and a guide tube; The wire is connected to the electrode on the handle; connecting the high-frequency electricity to the electrode can make the cutting blade electrified, and the lesion can be removed by high-frequency cutting during the operation. Because the present invention adopts the above-mentioned technical scheme, the knife head adopts a flat duck-tongue structure design, the knife head is composed of a perforated insulator and a metal electrode, and the injection needle passes through the hole of the insulator; the electric knife and the injection needle Combined into one instrument, the number of instrument replacements is reduced during the operation, the operation time is shortened, and the pain of the patient is relieved.

Description

technical field [0001] The invention relates to an apparatus for treating diseases of the digestive system and performing high-frequency tissue cutting on the digestive tract under the guidance of an endoscope, in particular to a high-frequency electric knife for endoscope with integrated cutting and injection functions. Background technique [0002] In recent years, with the development of endoscopic technology, endoscopic tissue biopsy, endoscopic mucosal resection, and endoscopic mucosal dissection have been widely used. The discovery, diagnosis and treatment of the disease have played a key role. The commonly used knives on the market are mainly Olympus IT insulated head knife, HOOT hook knife, TT triangular knife, Flex at least one wire knife, etc. When performing surgery under the guidance of the endoscope, the endoscope first enters the human body to find Lesions, the instrument enters the human body from the endoscopic forceps to mark the lesion. After marking, the ...
