Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] As Figures 1-6 shown, a medical optical instrument protective cover comprises a protective cover body 1 and a lens cover shell 2. The protective cover body 1 is a cylindrical structure with one end open and the other end closed. The lens cover shell 2 is installed at the closed end of the protective cover body 1. The lens cover shell 2 is an annular structure. The outer end face and the inner end face of the lens cover shell 2 have an included angle. A lens 3 is installed at a position inside the lens cover shell 2 close to the outer end face. The lens 3 is parallel to the outer end face of the lens cover shell 2.

[0034] The protective cover body 1 is used for protecting the lens arm part of the optical instrument, which can be transparent PE material, which can adopt a piece of PE film, and the side seam edge and one end are closed by welding, and then the corresponding installation port is cut on the lens cover shell 2.

[0035] The lens cover shell 2 and the lens 3 installed therein are used for protecting the lens of the optical instrument, wherein the inner end face of the lens cover shell 2 is coaxial with the protective cover body 1, and the outer end face of the cover shell body is inclined relative to the inner end face, so as to better cooperate with the lens part of the optical equipment.

[0036] Preferably, the included angle between the inner end face and the outer end face of the lens cover shell 2 is 5°.

[0037] The width of the protective cover body 1 is greater than the outer diameter of the lens cover shell 2, in order to connect the lens cover shell 2 to the end of the protective cover body 1, the closed end of the protective cover body 1 is a circular truncated cone structure 4 with a gradually reduced inner diameter towards the end end, and the lens cover shell 2 is installed at the end of the circular truncated cone structure 4.

[0038] In order to realize the fixation between the protective cover body 1 and the lens cover shell 2, the outer end edge of the circular truncated cone structure 4 is welded on the inner end face of the lens cover shell 2.

[0039] Specifically, the outer diameter of the side where the inner end face of the lens cover shell 2 is located is greater than the outer diameter of the side where the outer end face is located, the end of the circular truncated cone structure 4 is an installation port, and the edge of the installation port is directly fixed on the annular face of the inner end face of the lens cover shell 2 by welding.

[0040] In order to adapt to the operating rod part on the lens arm, the side of the circular truncated cone structure 4 is provided with a secondary sleeve 5 symmetrical about the axis of the protective cover body 1, and the end of the secondary sleeve 5 is closed.

[0041] When the protective cover body 1 is sleeved on the lens arm, the operating rod directly penetrates into the secondary sleeve 5, so that the doctor can control the lens movement by hand.

[0042] In order to facilitate the installation of the lens 3, the annular groove I 6 for installing the lens 3 is arranged on the inner ring face of the lens cover shell 2 close to the outer end face, and the radial plane of the annular groove I 6 is parallel to the outer end face of the lens cover shell 2.

[0043] In order to install the lens 3 into the annular groove I 6, the side wall of the annular groove I 6 towards the outer end face of the lens cover shell 2 is an elastic end face.

[0044] The annular groove I 6 is located close to the outer end surface of the lens cover shell 2, and the outer end surface of the lens cover shell 2 and the part outside the lateral wall of the annular groove I 6 adopt an elastic end surface, which can be pulled to be opened to facilitate the installation of the lens 3 into the annular groove I 6.

[0045] Since the entire lens cover shell 2 is made of PE material, in order to increase the strength of the entire lens cover shell 2 and at the same time play a good supporting role on the lens, an annular groove II 7 is arranged on the inner ring surface of the lens cover shell 2, the radial plane of the annular groove II 7 is parallel to the inner end surface of the lens cover shell 2, and a metal ring piece 8 is installed in the annular groove II 7.

[0046] The annular groove II 7 is located inside the annular groove I 6.

[0047] In order to facilitate the installation of the metal ring piece 8, an inclined surface is arranged on the inner ring surface of the lens cover shell 2 inside the annular groove II 7.

[0048] Specifically, two-stage inclined surfaces are arranged on the inner side of the annular groove II 7, including an inclined surface I 9 and an inclined surface II 10 in sequence from the inner end surface of the lens cover shell 2, there is a vertical surface transition between the inclined surface I 9 and the inclined surface II 10, and both the inclined surface I 9 and the inclined surface II 10 are inclined surfaces with the outer end inclined inward, so that when the metal ring piece 8 is installed into the annular groove II 7 from the inner end surface side of the lens cover shell 2, it can be guided, thereby facilitating the installation of the metal ring piece 8.

[0049] Preferably, the inclination angle of the inclined surface II 10 is smaller than the inclination angle of the inclined surface I 9, and the inclination angle is the included angle between the inclined surface and the axis of the inner end surface of the lens cover shell 2.

[0050] In order to cooperate with the lens of the optical instrument, an assembly groove 11 is arranged on the inner ring surface of the lens cover shell 2, the assembly groove 11 extends from the inner end surface of the lens cover shell 2 to the outer end surface thereof in the direction, and communicates with the annular groove II 7.

[0051] The assembly groove 11 is provided with two assembly grooves, which are symmetrical with the axis of the inner end surface of the lens cover shell 2, can be used for matching the structure on the lens, plays a positioning and limiting role, and thereby ensures the accuracy of cooperation between the lens cover shell 2 and the lens.

[0052] In addition, the assembly groove 11 extends to the annular groove II 7, which can further increase the convenience of installation of the metal ring piece 8.

[0053] Preferably, a boss 12 protruding outward is arranged on the outer wall of the lens cover shell 2 at the position of the assembly groove 11, so as to ensure the thickness at the assembly groove 11 and the structural strength of the entire lens cover shell 2.

[0054] After the protective cover body 1 is sleeved on the lens arm, in order to fix it with the lens arm, the outer surface of the protective cover body 1 is provided with a plurality of binding belts 13 with double-sided adhesive tape 14 at both ends.

[0055] The binding belt 13 can be fixed on the outer surface of the protective cover body 1 by welding, and after the protective cover body 1 is sleeved on the lens arm, the centrifugal paper on the double-sided adhesive tape 14 can be torn off, so that the protective cover body 1 is tightly bound on the lens arm by the binding belt 13 and the double-sided adhesive tape 14, thereby improving the protection effect.

[0056] When the optical instrument is used for assisting surgery or examination, the protective cover needs to be first sleeved on the lens arm of the optical instrument, that is, the lens is inserted into the protective cover body 1 from the opening end of the protective cover body 1 until the lens cooperates with the lens cover 2 and the operating rod is inserted into the corresponding auxiliary sleeve 5, and then the protective cover body 1 is sleeved on the entire lens arm, and finally the protective cover body 1 is bound with the lens arm by the binding belt 13, so that the optical instrument can be used. During use, the entire protective cover can prevent contaminants from polluting and damaging the lens and the lens arm, ensure good protection of the optical instrument, avoid cross infection, and facilitate the operation and use of the doctor.

[0057] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
