The invention belongs to the technical field of medical instruments, and particularly relates to a high-frequency electric instrument used in cooperation with an endoscope. The high-frequency electric instrument comprises a thumb ring, a first push-pull finger ring, a second push-pull finger ring and a connecting rod, wherein the first push-pull finger ring comprises an injection interface, the second push-pull finger ring comprises an electrode base, an electrode and a conductive elastic piece are installed in the electrode base, a metal catheter is installed in the injection connector, the electrode is electrically connected with the metal catheter through a conductive elastic piece, an insulator is installed at the lower end of a sheath tube, a needle knife is arranged in the insulator in a penetrating mode, a vertically-through central inner cavity is formed in the needle knife, an end cap is arranged on the lower portion of the needle knife, the lower end of the needle knife protrudes out of the end cap, and the needle knife is connected with the metal catheter. The high-frequency electric instrument has the advantages that the needle knife is provided with the vertically-through central inner cavity, so the needle knife can both function as an injection needle and a high-frequency knife, instruments with different functions can be selected according to different conditions in an operation, instrument replacement frequency in an operation process is greatly reduced, operation efficiency is improved, and the pain of a patient is relieved.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a high-frequency electrical device used in conjunction with an endoscope. Background technique [0002] With the development of endoscopic technology and other related technologies, the treatment and screening of early gastrointestinal cancer under endoscopy has become the preferred treatment method at present. At present, the routine treatment of early digestive tract cancer often requires the cooperation of many devices. For example: first use an injection needle to dye or inject the lesion to make it bulge, then use an electric knife to cut or strip it, and finally use a hemostatic clip or an electric knife or an injection needle to suture or stop bleeding. The operation process is cumbersome and the equipment is replaced frequently, which not only reduces the operation efficiency but also requires high professional skills of doctors. Instrument replaceme...
