Description

Endoscope handle location limited slip structure

Technical Field

The utility model relates to an endoscope handle location limited slip structure.

Background

The endoscope is designed to be easily inserted into a human body to perform examination or treatment mainly by a catheter with a very small diameter, and the state in the human body is shot by a lens module arranged at the outer end of the catheter, and the image is transmitted to the outside to be observed by medical staff so as to achieve the purposes of diagnosis and treatment. In practice, after the catheter is inserted into the human body, in order to obtain a comprehensive observation, the bending angle of the tail end of the catheter must be adjusted, and conventionally, one end of a connecting wire accommodated in the catheter is fixed on a rotating wheel inside a handle, and a knob outside the handle is rotated to drive the rotating wheel to rotate so as to pull the connecting wire to change the bending angle of the tail end of the catheter. Since the catheter will generate a return elastic force when bending, users often need to press the fingers on the knob all the time, causing inconvenience in use, and easily cause injury due to rebounding of the tail end of the catheter when releasing their hands carelessly, so the conventional design needs to be improved.
