Above-mentioned technical proposal is connect, the optical system mounting hole includes optical lens protection eyeglass mounting hole and optical lens
Mounting hole.
Connect above-mentioned technical proposal, the cross sectional shape in light shafts encapsulation channel and the shape one of the optical fibre illumination window
It causes.
Above-mentioned technical proposal is connect, the sectional area that the optical fibre illumination window and the light shafts encapsulate channel is crescent.
Above-mentioned technical proposal is connect, the insertion tube is steel pipe, is mounted in the first end cap.
Above-mentioned technical proposal is connect, the tail end in fiber optic bundle encapsulation channel is equipped with holding section, also is provided on the fiber optic bundle
Corresponding auxiliary section.
Above-mentioned technical proposal is connect, the fiber optic bundle is fixed on the fiber optic bundle by viscose glue and encapsulates in channel.
Above-mentioned technical proposal is connect, the light shafts encapsulation is arc-shaped on the outside of channel.
Above-mentioned technical proposal is connect, the optical fibre illumination window is placed in below the optical system mounting hole.
Above-mentioned technical proposal is connect, the optical fibre illumination window surrounds the optical system mounting hole.
The beneficial effect comprise that：The present invention opens up optical fibre illumination window in the end of the leading end portion of endoscope,
At the rear of optical fibre illumination window, the light shafts of design and leading end portion one encapsulate channel, to improve endoscope leading end portion
Space utilization rate increases optical fibre illumination area.
