Abstract

An endoscope comprising a lens, and an anti-fog film, wherein an optically clear adhesive bonds the anti-fog film to the lens or lens section.

Claims

exact text as granted — not AI-modified
1 .- 20 . (canceled) 
     
     
         21 . A lens for use with an endoscope, the lens comprising an anti-fog film having a first side applied to the lens, and a second side, the anti-fog film comprising an anti-fog coating applied to the second side, and a detectable element applied to the anti-fog film that allows the anti-fog film to be detected in the event the anti-fog film is dislodged from the lens during use. 
     
     
         22 . The lens according to  claim 21 , wherein an optically clear adhesive bonds the anti-fog film to the lens. 
     
     
         23 . The lens according to  claim 22 , wherein the optically clear adhesive is a temporary adhesive providing a temporary bond between the anti-fog film and the lens. 
     
     
         24 . The lens according to  claim 23 , wherein the anti-fog film is preformed to fit the lens. 
     
     
         25 . The lens according to  claim 22 , wherein the optically clear adhesive is pre-applied to the anti-fog film. 
     
     
         26 . The lens according to  claim 21 , wherein the lens is silicone. 
     
     
         27 . The lens according to  claim 26 , wherein the anti-fog coating is a hydrophilic coating. 
     
     
         28 . The lens according to  claim 21 , wherein the anti-fog coating is a hydrophilic coating. 
     
     
         29 . The lens according to  claim 21 , wherein the detectable element is applied on the first side of the anti-fog film that is applied to the lens. 
     
     
         30 . The lens according to  claim 29 , wherein the detectable element is applied on an outer edge of the first side of the anti-fog film. 
     
     
         31 . The lens according to  claim 29 , wherein the detectable element is applied on an outer perimeter of the first side of the anti-fog film. 
     
     
         32 . The lens according to  claim 21 , wherein the detectable element is an opaque material and is visible by the naked eye. 
     
     
         33 . The lens according to  claim 21 , wherein the detectable element is a material that fluoresces under a UV light. 
     
     
         34 . The lens according to  claim 21 , wherein the detectable element is a radio-opaque material that can be detected using x-rays. 
     
     
         35 . The lens according to  claim 34 , wherein the radio-opaque material is selected from the group consisting of a metal, barium sulfate, ceramic, graphite, and bismuth. 
     
     
         36 . The lens according to  claim 21 , wherein detectable element is applied onto the anti-fog film using a method selected from the group consisting of printing, plating, and painting. 
     
     
         37 . The lens according to  claim 21 , wherein detectable element is applied by molding or forming into or onto the anti-fog film.
