Optical Cap for Use With Arthroscopic System
First Claim
Patent Images
1. A cap for use on the distal end of an arthroscopic instrument, said cap comprising:
- a cap face having first and second fluid flow channels and first and second light output openings on the cap face;
a first molded tube having a proximal and distal end, the proximal end having a mirror adapted to reflect light through the first molded tube and the first molded tube attached to the cap face so that the distal end of the molded tube terminates at the first light output opening on the cap face;
a second molded tube having a proximal and distal end, the proximal end having a mirror adapted to reflect light through the first molded tube and the second molded tube attached to the cap face so that the distal end of the molded tube terminates at the second light output opening on the cap face;
a first LED positioned at the proximal end of the first molded tube;
a second LED positioned at the proximal end of the second molded tube; and
where the cap is arranged in viewing direction of the arthroscopic instrument.
