The surgical headlight system can further include a headwear structure, configured to be worn on a surgeon's head during surgery, supporting the headlamp. The surgical headlight system can further include a video camera configured to record surgery. The headlamp, the headwear structure and the video camera all have an exterior surface. An antimicrobial coating is applied to the exterior surface of the headlamp, the exterior surface of the video camera, and/or the exterior surface of the headwear structure. The antimicrobial coating includes a silane quaternary ammonium ion or salt thereof. The antimicrobial coating imparts antimicrobial properties onto the exterior surface to which it is applied, such as the exterior surface of the headlamp. The silane quaternary ammonium ion or salt thereof can be one or more of 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. ## Claims ### Claim 1 A surgical headlight system comprising: a headlamp including an exterior surface; and an antimicrobial coating applied to the exterior surface of the headlamp; wherein, the antimicrobial coating includes isopropyl alcohol and one or more of: 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. ### Claim 2 (depends on 1) The surgical headlight system of claim 1, wherein, the antimicrobial coating further includes one or more of: 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride. ### Claim 3 (depends on 1) The surgical headlight system of claim 1 further comprising: a headwear structure, configured to be worn on a surgeon's head during surgery, supporting the headlamp, the headwear structure including an exterior surface; and wherein, the antimicrobial coating is additionally applied to the exterior surface of the headwear structure. ### Claim 4 (depends on 1) The surgical headlight system of claim 1 further comprising: a video camera configured to record a surgery, the video camera including an exterior surface; wherein, the antimicrobial coating is additionally applied to the exterior surface of the video camera. ### Claim 5 (depends on 1) The surgical headlight system of claim 1 further comprising: a cable attached to the headlamp, the cable including an exterior surface; wherein, the antimicrobial coating is additionally applied to the exterior surface of the cable. ### Claim 6 (depends on 1) The surgical headlight system of claim 1 further comprising: a color temperature filter attached to the headlamp, the color temperature filter having an exterior surface; wherein, the antimicrobial coating is additionally applied to the exterior surface of the color temperature filter. ### Claim 7 (depends on 1) The surgical headlight system of claim 1 further comprising: binocular loupes including an exterior surface; wherein, the antimicrobial coating is additionally applied to the exterior surface of the binocular loupes. ### Claim 8 (depends on 1) The surgical headlight system of claim 1 further comprising: a transmitter including an exterior surface; wherein, the antimicrobial coating is additionally applied to the exterior surface of the transmitter. ### Claim 9 A method of imparting antimicrobial properties onto an exterior surface of a surgical headlight system comprising: presenting a surgical headlight system including a headlamp including an exterior surface; and applying, to the exterior surface of the headlamp, a solution including isopropyl alcohol and one or more of: 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. ### Claim 10 (depends on 9) The method of claim 9, wherein, the one or more of: 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride is between 0.1 percent and 10 percent by weight of the solution. ### Claim 11 (depends on 10) The method of claim 10, wherein, the isopropyl alcohol is between 30 percent to 90 percent by weight of the solution. ### Claim 12 (depends on 11) The method of claim 11, the surgical headlight system further including a headwear structure, configured to be worn on a surgeon's head during surgery, supporting the headlamp, the headwear structure including an exterior surface; and the method further comprising applying the solution to the exterior surface of the headwear structure. ### Claim 13 (depends on 11) The method of claim 11, the surgical headlight system further including a video camera configured to record a surgery, the video camera including an exterior surface; and the method further comprising applying the solution to the exterior surface of the video camera. ### Claim 14 (depends on 11) The method of claim 11, the surgical headlight system further including a cable attached to the headlamp, the cable including an exterior surface; and the method further comprising applying the solution to the exterior surface of the cable. ### Claim 15 A surgical headlight system comprising: a headwear structure; an adjustable arm attached to the headwear structure; a headlamp connected to the adjustable arm; and binocular loupes connected to the adjustable arm; wherein, each of the headwear structure, the headlamp, and the binocular loupes include an exterior surface and an antimicrobial coating applied to the exterior surface; and wherein, the antimicrobial coating comprises one or more of: 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride.
