Abstract

Described herein generally are surgical pencils which provide a physician with illumination of a surgical site. The surgical pencils described herein can be retrofitted with a lighting device, can be manufactured incorporating a lighting device or can be fitted with a preformed lighting device.

Claims

1. A surgical pencil for providing an illuminated surgical site comprising:

a surgical instrument having a first end, a second end, and elongated structure and a surgical tool associated with the first end; and

a removable lighting device associated with said first end of said surgical instrument and operatable by a surgeon having a power button, at least one light and a mating mechanism to connect said removable lighting device to said surgical instrument.

2. The surgical pencil according to claim 1 wherein said removable lighting device is formed of an elastic polymer.

3. The surgical pencil according to claim 1 wherein said removable lighting device is formed of a rigid polymer.

4. The surgical pencil according to claim 3 wherein said mating mechanism has a shape that can compliment at least one shape included on said surgical instrument and thereby secure said removable lighting device to said surgical instrument.

5. The surgical pencil according to claim 1 wherein said at least one light is a fiber optic lighting element.

6. The surgical pencil according to claim 1 wherein said at least one light is an LED light.

7. The surgical pencil according to claim 5 wherein said at least one light is provided in a circular arrangement.

8. The surgical instrument according to claim 1 wherein said removable lighting device is powered by a built-in battery.

9. The surgical pencil according to claim 1 wherein said removable lighting device is disposable.

10. The surgical pencil according to claim 1 wherein said removable lighting device is reusable with the same surgical instrument or a different surgical instrument.

11. The surgical pencil according to claim 1 wherein said removable lighting device is safe to at least one sterilization technique.

12. The surgical pencil according to claim 11 wherein said at least one sterilization technique is gamma irradiation, pressure sterilization or steam sterilization.

13. A lighting device comprising:

a power button, at least one light, a housing and a mating mechanism to connect said lighting device to a surgical instrument.

14. The lighting device according to claim 13 wherein said mating mechanism is an expandable housing formed of an elastic polymer.

15. The lighting device according to claim 14 wherein said elastic polymer is a rubber.

16. The lighting device according to claim 13 wherein said housing is formed of a rigid polymer.

17. The lighting device according to claim 13 wherein said mating mechanism has a shape that can compliment at least one shape included on said surgical instrument and thereby secures said removable lighting device to said surgical instrument.

18. The lighting device according to claim 13 wherein said at least one light is a fiber optic lighting element.

19. The lighting device according to claim 13 wherein said at least one light is an LED light.

20. The lighting device according to claim 13 wherein said at least one light is provided in a circular arrangement.
