Endoscopes in clinical applications at this stage have difficulty guiding instruments to a target site within a narrow lumen. In the operation process, doctors need to continuously rotate and move the endoscope to adjust the bending direction and the bending angle of the bending part to complete the omnibearing observation of the cavity and the transportation of instruments. When the bending direction of the endoscope is large, the hand holding the endoscope needs to be twisted together, which is very laborious and inconvenient, and meanwhile, doctors have different habits of holding the endoscope during operation, and some doctors are used to hold the connecting position of the endoscope light guide part and the handle to adjust the bending of the endoscope, and the operation habit influences the exertion of the operation level of the doctors to a certain extent. Meanwhile, the outer protective layer at the connecting position of the light guide part and the handle is easy to damage, and the service life of the endoscope is shortened.
