Method for remotely cooling a scope-mounted (distal) arthroscopic light source
A surgical light source system for cooling high-powered arthroscopic light emitters. The surgical light source system includes a housing having a proximal end and a distal end with a tube connected to the proximal end. The system also includes a light source at the distal end of the housing which is connected to a remote power source. The system has a plurality of fins extending around the light source within the housing and a remote fan connected to the tube. The remote fan is adapted to draw air across the fins, forming a heatsink within the housing.
1. A surgical light source system, comprising:
a housing positioned at a distal end of the surgical light source system with a tube connected to a proximal end of the housing;
a shared housing containing a remote fan and a remote power source;
a light source disposed at a distal end of the housing and connected to the remote power source;
a plurality of fins extending around the light source within the housing; and
a remote fan connected to the tube, the remote fan being adapted to draw air across the fins, forming a heatsink within the housing.
2. The system of claim 1 , further comprising a power wire connecting the light source to the remote power source.
3. The system of claim 2 , wherein the power wire extends through the tube.
4. The system of claim 1 , further comprising a cap extending over the distal end of the housing.
5. The system of claim 4 , wherein the cap has a central aperture substantially aligned with the light source.
6. The system of claim 5 , wherein the cap has one or more slots between the central aperture and an outer circumference of the cap, the one or more slots extending through the cap.
7. The system of claim 1 , wherein the plurality of fins extend radially from the light source.
8. The system of claim 7 , wherein each of the plurality of fins extends along a plane parallel to or substantially aligned with a central longitudinal axis extending through the housing.
9. The system of claim 6 , wherein air current is pulled proximally by the fan through the one or more slots in the cap, across the fins, and through the tube.
10. The system of claim 1 , wherein the power source emits an adjustable output current.
11. The system of claim 10 , wherein increasing the output current increases an illuminance of the light source and decreasing the output current deceases the illuminance of the light source.
12. The system of claim 1 , wherein the light source is a LED light.
13. The system of claim 12 , wherein the light source is a COB LED light.
14. The system of claim 1 , wherein the tube is composed of polyethylene tubing.
15. The system of claim 1 , wherein the housing is composed of plastic.
16. The system of claim 1 , wherein the housing is cylindrical.
