Abstract
Abstract A surgeons headlight system which comprises a short arc xenon lamp in optical communication with a proximal end of a light pipe. The light pipe having beam shaping optics located at a distal end thereof. The light pipe also having a first long section which is fixed in an elevated manner and a second tethered section which defines, at least in part, an umbilical. The distal end of the light pipe which comprises the beam shaping optics being supported solely by the surgeons cap. The headlight system delivering illumination of not less than 2500 foot candles over a three inch diameter circle, and causing less than 10 grams of pull to the surgeons cap.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A surgeon's disposable headlight system which comprises: a surgeon's cap; a disposable light pipe having a proximal end and a distal end, the proximal end adapted to be placed in optical communication with a short arc xexon lamp light source, the distal end secured to the surgeon's cap; beam-forming optics secured solely to the surgeon's cap and in optical communication with the distal end of the light pipe, the light pipe being less than about 2 millimeters in diameter.
Claim 2
Dependent Claim
79 words
A surgeon's disposable headlight system which comprises: a surgeon's cap; a disposable light pipe having a proximal end and a distal end, the proximal end adapted to be placed in optical communication with a short arc xexon lamp light source, the distal end secured to the surgeon's cap; beam-forming optics secured solely to the surgeon's cap and in optical communication with the distal end of the light pipe, the light pipe being less than about 2 millimeters in diameter.
Claim 3
Dependent Claim
18 words
The system of claim 1 which includes: means to package the disposable headlight system in a sterile condition.
Claim 4
Dependent Claim
142 words
A surgeon's headlight system which comprises: a short arc xexon lamp light source; a light pipe having a proximal end in optical communication with the light source and a distal end in communication with beam-shaping optics; the light pipe comprising a first long section which is secured in a fixed elevated manner and a second tethered section which depends from the long section and defines along its length at least in part an umbilical; means to place the distal end in optical communication with the beam-shaping optics; means to secure the distal end to a surgeon's caps, which cap solely supports the beam-shaping optics wherein the illumination delivered by the system is not less than 2500 foot candles over a 3 inch diamater circle and the force acting surgeon's cap due to the light pipe is less than 10 grams of pull.
Claim 5
Dependent Claim
142 words
A surgeon's headlight system which comprises: a short arc xexon lamp light source; a light pipe having a proximal end in optical communication with the light source and a distal end in communication with beam-shaping optics; the light pipe comprising a first long section which is secured in a fixed elevated manner and a second tethered section which depends from the long section and defines along its length at least in part an umbilical; means to place the distal end in optical communication with the beam-shaping optics; means to secure the distal end to a surgeon's caps, which cap solely supports the beam-shaping optics wherein the illumination delivered by the system is not less than 2500 foot candles over a 3 inch diamater circle and the force acting surgeon's cap due to the light pipe is less than 10 grams of pull.
Claim 6
Dependent Claim
49 words
The system of claim 3 which comprises: means to disconnect the second tethered section to form a depending light pipe having a free end and a disposable light pipe, the distal end secured to the surgeon's headgear and the other end adapted to be connected to the free end.
Claim 7
Independent Claim
20 words
The system of claims 3 or 4 which includes a plurality of light pipes in communication with the light source.
Claim 8
Dependent Claim
19 words
The system of claim 5 wherein the beam-shaping optics is less than 1 1/2 centimeters in its longest dimension.
Claim 9
Dependent Claim
19 words
The system of claim 4 which comprises: a plurality of light pipes in communication with a single light source.
Claim 10
Dependent Claim
16 words
The system of claim 7 which comprises: means to switch the illumination among the light pipes.
Claim 11
Dependent Claim
20 words
The system of claim 7 which comprises: a plurality of light sources; and means to alternate between the light sources.
