Abstract

Lighting systems for surgical retractors.

Claims

1. An illuminated surgical retractor comprising:

a retractor having a handle portion and a blade portion;

a light emitting diode disposed on the blade portion;

a battery disposed on the handle portion;

a conductor for delivering power from the battery to the LED;

means for releasably securing the battery, conductor and LED to the retractor.

2. An illuminated surgical retractor comprising:

a retractor having a handle portion and a blade portion;

a light emitting diode disposed on the handle portion;

a battery disposed on the handle portion;

a lens disposed on the blade portion;

a optical fiber for delivering light from the LED to the lens;

means for releasably securing the battery, conductor and LED to the retractor.

3. A light engine for use with a surgical retractor comprising:

a light emitting diode adapted for mounting on a blade portion of the retractor;

a battery adapted for mounting on a handle portion of the retractor;

a conductor for delivering power from the battery to the LED;

each of said light emitting diode, battery, and conductor being disposed upon a releasably securable tape for releasably securing the light engine to the retractor.

4. A light engine for use with a surgical retractor comprising:

a light emitting diode adapted for mounting on a handle portion of the retractor;

a battery adapted for mounting on a handle portion of the retractor;

a lens adapted for mounting on a blade portion of the retractor;

a optical fiber for delivering light from the light emitting diode to the lens;

each of said light emitting diode, battery, lens and optical fiber being disposed upon a releasably securable tape for releasably securing the light engine to the retractor.
