[0002] Medical electronic endoscopes are commonly used medical devices. Their high cost is closely related to their precise manufacturing. Especially the distal end seat of the endoscope, which includes a window glass for protecting the illumination optical fiber and a protective glass for protecting the imaging module. The sizes of these two parts are extremely small, and the entire assembly process needs to be operated under a microscope. Especially in the glue-applying process operation link, it completely depends on skilled workers to stick glue with the tip of the glue dispenser and then apply a circle of glue along the outer contour of the window glass to fix it.

[0003] During the glue application process on the outer contour of the traditional endoscopic optical window, if the hand shakes slightly during the operation, the glue will flow onto the surface of the window glass, affecting the illumination and imaging quality. Content of the Utility Model

[0004] The purpose of the utility model is to provide a glue-applying protective cover for an endoscopic optical window, which solves the problem that during the glue application process on the outer contour of the traditional endoscopic optical window, if the hand shakes slightly during the operation, the glue will flow onto the surface of the window glass, affecting the illumination and imaging quality.

[0005] The embodiment of the present application provides a glue-applying protective cover for an endoscopic optical window, including an inner lens distal end seat. An outer wall of the upper end of the inner lens distal end seat is provided with a protective cover main body.

The upper end of the inner lens distal end seat is provided with and placed a window glass and a protective glass, and the positions of the annular glue-applying grooves correspond to those of the window glass and the protective glass.

[0006] By adopting the above technical solution, after the worker only needs to drop glue into the annular glue-applying groove, the glue flows from the slope surface of the annular glue-applying groove to the periphery of the window glass and the protective glass. A novice can also perform the glue application operation without the need for a skilled worker. After the glue application is completed, the protective cover main body can be gently pulled out and removed upward. After wiping off the glue in the groove of the protective cover main body, it can be reused or used once, thus ensuring the illumination and imaging quality of the window glass surface.

[0007] Optionally, a plurality of groove bottom glue leakage holes are formed on an inner wall of the protective cover main body located inside the plurality of annular glue-applying grooves, and the groove bottom glue leakage holes extend to the periphery of the window glass and the protective glass.

[0008] By adopting the above technical solution, the arrangement of the groove bottom glue leakage holes can facilitate the glue to slide to the periphery of the glass, and then glue the periphery of the glass.

[0009] Optionally, an instrument hole is provided on the upper side of the inner lens end seat.

[0010] By adopting the above technical solution, objects can be placed and stored through the instrument hole.

[0011] Optionally, a positioning boss is provided at the lower end of the protective cover body, and the position of the positioning boss corresponds to the position of the instrument hole.

[0012] By adopting the above technical solution, the protective cover body can be positioned by the positioning boss corresponding to the instrument hole.

[0013] Optionally, the inner wall of the protective cover body located around the annular gluing groove is provided with an annular groove slope.

[0014] By adopting the above technical solution, the setting of the annular groove slope can facilitate the falling of the glue.

[0015] Optionally, a connecting section is provided on the inner wall of the protective cover body between the multiple groups of groove bottom glue leakage holes.

[0016] By adopting the above technical solution, the connecting section can play a connecting role with the annular gluing groove of the protective cover body.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] The technical solution of the present application is that a worker only needs to drip glue into the annular gluing groove, and the glue will flow from the slope of the annular gluing groove to the periphery of the light window glass and the protective glass. A novice can also perform the gluing operation without the need for skilled workers. After the gluing is completed, the protective cover body can be gently pulled out and removed, and the glue in the groove of the protective cover body can be wiped off and can be reused or used once, thereby ensuring the lighting and imaging quality of the light window glass surface.
