Disposable polyp tightening and removing device

Abstract

The invention discloses a disposable polyp tightening and removing device, which comprises a handle, a guide connector is connected to the lower end of the handle in a penetrating mode, an outer pipe is connected to the interior of the guide connector in an adhesive mode, a connecting rod is connected to the interior of the outer pipe in a penetrating mode, an inhaul cable is connected to the surface of the connecting rod in a welded mode, and a connecting pipe is connected to the lower end of the inhaul cable in a welded mode. The disposable polyp tightening and removing device enters the human body cavity through the working cavity of the endoscope to perform polyp tightening and removing work. If flat polyp in the human body cavity is not prone to being sleeved, normal saline can be injected into the flat polyp through an injection needle, then the raised polyp is sleeved with the tightening and removing sleeve, then the device connecting line is connected, and the polyp tightening and removing work is completed through high-frequency output. The device is simple in structure and convenient to use, the operation efficiency is effectively improved, the treatment effect is improved, and meanwhile the problems that due to the complex structure, a traditional tightening and removing device is inconvenient to use, and the operation efficiency cannot be effectively improved are solved.

Description

technical field [0001] The invention relates to the technical field of medical and sanitary products, in particular to a disposable polyp snare. Background technique [0002] The disposable polyp snare is mainly used for excision of various polyps and redundant tissues under the endoscope with high-frequency electricity. The basic structure of the existing snare is: a movable ring is set on the tubular handle, and the tubular handle The front end of the sheath tube is fixedly connected with the tail end of the sheath tube, and the ring is connected with both ends of the metal wire; one end of the metal wire forms a ring, extending from the tubular handle to the front end of the cannula. To the diseased part in the human body, when the finger ring moves forward relative to the handle, the metal wire ring will protrude from the front end of the cannula, and automatically form a snare under the elastic expansion of the metal itself. Put it on the polyp, and then gradually move...
