As a further elaboration, the sealing ring is connected to the endoscope and the catheter by gluing.

As a further explanation, the concave lens, the convex lens, the wide-angle lens and the transparent glass sheet are fixedly arranged inside the lens barrel according to the arrangement mode of the wide-angle lens, the concave lens, the convex lens and the transparent glass sheet.

By way of further illustration, the handle and the catheter are formed as an integrally molded structure.

By way of further illustration, the outer surface of the catheter is wrapped with at least two polyethylene layers.

As a further illustration, the end of the eyepiece is provided with a lens opening for viewing.

To sum up, the utility model discloses following beneficial effect has: the utility model relates to an integral type is used for endoscopic medical camera, simple structure can make the pipe stand wear and tear nature strong through set up multilayer polyethylene layer at the pipe surface, and life is high, and is fixed endoscope and pipe through using the sealing ring, can avoid the endoscope to break away from, can make medical camera observe brighter through setting up lighting device, can make the formation of image clearer through setting up endoscope and eyepiece.
