Quantitative propelling type endoscope looping and binding device

Abstract

The invention relates to a quantitative advancing endoscope ligating device which comprises ligating ring, carrier pipe, push rod, outer pipe, inner pipe, tail cover, annular piston, water storage pipe, water filling pipe and water pumping hole, wherein the outer pipe and inner pipe are coaxially fixed on the tail cover; annular piston is posited on the bottom of the coaxial annular spacing which is formed by the outer pipe and inner pipe; the ligating ring is assembled in turn on the out surface of inner pipe inside the coaxial annular spacing; one end of the carrier pipe is connected with the bottom of coaxial annular spacing, while the other end is connected with the exit of water filling pipe; push rod is inserted into the water filling pipe; water storage pipe is posited on the out side of water filling pipe; water pumping hole is posited on the lower part of water filling pipe near exit and is connected with water storage pipe.

Description

Technical field: [0001] The invention relates to a medical instrument device, in particular to a quantitative push-type endoscope ligation device used in conjunction with a medical endoscope. Background technique: [0002] In the prior art, the endoscope ligation device is installed at the front end of the endoscope, and can be used in conjunction with the endoscope to treat varicose vein diseases in the esophagus, gastrointestinal and other parts of the human body. The U.S. patent "Endoscope ligature", the patent number is 5624453, and the application date is April 29, 1997. It discloses a ligator that pulls the ligation ring from the endoscope sleeve one by one through a rope. The sleeve of the ligature is detached, and the ligation ring is placed on the lesion to be treated. The disclosed ligator has a complex structure and high cost. In use, the rope pulls the tube body of the endoscope, causing The position is moved, making it difficult for the banding ring to launch accurat...

U.S. Patent "Endoscope Ligator", the patent number is 5624453, and the application date is 1997.04.29. It discloses a ligation device, which pulls the ligation rings from the endoscope sleeve one by one The sleeve of the ligation device is separated from the sleeve, and the ligation ring is set on the lesion that needs to be treated. The disclosed ligation device has a complicated structure and high cost. During use, the rope pulls the tube body of the endoscope to bend, causing Position shifting, making accurate firing of the ligation loop difficult

The patent application number of the Chinese patent "endoscopic ligation device" is 200410000053.X, and the application date is 2004.01.06. The applicant discloses an endoscopic ligation device. Among the applied endoscopic ligation devices There is a backing ring that falls into the esophagus of the human body after the ligation operation, hindering the view of the endoscope and interfering with further surgical work
