Problems solved by technology

[0011] When the extension state of the guide wire is biased, it cannot stick to the guide groove of the forceps lifter and continue to protrude into the positioning bayonet at the top of the forceps lifter, but deviates from the forceps lifter and protrudes out of the storage space. In this case In this case, the guide wire cannot be positioned before and after the forceps lifter is lifted, so that the purpose of fixing the guide wire cannot be achieved, so that other treatment instruments cannot be guided to the predetermined position by the guide wire after being protruded from the instrument channel, and surgery cannot be performed

Abstract

The invention discloses an endoscope forceps lifting device, an endoscope head end and a duodenoscope system. The bottom of the endoscope forceps lifting device is communicated with an instrument channel and is provided with a hinge part which is hinged to a endoscope head end seat; the top of the endoscope forceps lifting device is provided with a positioning groove matched with a positioned piece; and the side edge of the endoscope forceps lifting device is provided with a shearing edge and a guide surface, and the guide surface is positioned between the positioning groove and the shearing edge. In the lifting process of the endoscope forceps lifting device, the shearing edge can move close to the inner side surface of the head end seat so as to guide the positioned piece in the first deflection extending state to the guide surface, the guide surface can guide the positioned piece into the positioning groove, and the positioning groove can be matched with an abutting fixing piece toclamp and fix the positioned piece so as to achieve the purpose of preventing the positioned piece from coming out of papilla and moving into the papilla, and enabling the operation to go smoothly.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope forceps lifter, an endoscope lens end and a duodenoscope system. Background technique [0002] Cancer is a general term for a large malignant tumor. Cancer cells are characterized by unlimited and endless proliferation, which consumes a large amount of nutrients in the patient's body. my country is a country with a large number of gastrointestinal diseases, and has long been trapped in the dilemma of low detection rate and high mortality rate of gastrointestinal diseases. At present, it is internationally recognized that the most effective way to fight cancer is early detection, early diagnosis and early treatment. Early diagnosis of cancer is a diagnosis and treatment method specifically for early cancer patients. Endoscopic diagnosis is the most representative type of early diagnosis of gastrointestinal cancer. [0003] Duodenoscopy refers to the meth...
