Abstract

The invention discloses a wedge-shaped locking and sealing structure of a camera handle key, which is characterized in that a wedge-shaped locking piece is arranged in a camera handle from outside toinside, and the direction of extrusion force is changed through a wedge-shaped inclined plane, so that key silica gel is extruded by a key fixing plate and the inner surface of the camera handle, andthe sealing of the position of the camera handle key is realized; and the sealing and mounting modes are effective and reliable.

Description

technical field [0001] The invention relates to a camera handle of a medical endoscope, in particular to a partial wedge-shaped locking sealing structure of the camera handle, and belongs to the technical field of medical instruments. Background technique [0002] The camera handle is an indispensable part of the endoscopic camera system. It is one of the extension devices for the doctor's vision in the process of minimally invasive surgery in the medical field. Whether the image recognition function of the CMOS chip in the camera handle is normal and the image clarity will directly affect the Affect the progress of minimally invasive surgery. Usually, the existence of dust particles and water vapor will make the doctor's judgment biased. Generally speaking, the camera handle adopts a fully enclosed structure, and the rear end (cable entry end) and front end (C-Mount interface end) are usually designed as Regular shape, so conventional sealing means can be used, such as O-r...
