Abstract

A surgical illumination device is disclosed. The device has a light source mounted at the end of a flexible boom. The boom is attached to a housing containing a battery and an electronic controller. A switch actuator on the housing allows a user to turn the device on and off through the controller.

Claims

1. An illumination device comprising:

an electrically powered light source;

a flexible boom having a first end on which said light source is mounted;

a housing attached to a second end of said boom opposite to said first end;

an electric battery located within said housing, said battery being operatively associated with said light source for providing power thereto;

a controller electrically connected to said battery and said light source for controlling the electrical power provided to said light source, and

a switch mounted on said device and in communication with said controller so as to provide a signal to said controller when said switch is actuated, said controller being actuated by said switch to control the electrical power to the light source for turning the light source on and off.

2. An illumination device according to claim 1, wherein said light source comprises a light emitting diode.

3. An illumination device according to claim 1, further comprising a lens mounted on said boom overlying said light source, said lens focusing light emitted from said light source.

4. An illumination device according to claim 1, further comprising means for pulsing the light source between high and low currents at a rate undetectable by the human eye so as to appear substantially continuous.

5. An illumination device according to claim 1 further comprising means for debouncing to minimize false signals from said switch.

6. An illumination device according to claim 1 further comprising at least one cradle shaped to receive and support said housing therein, said housing being releasably attachable to said cradle.

7. An illumination device according to claim 6 wherein said cradle includes a mounting strap attached thereto, said mounting strap being adjustable for attaching said illumination device to another item such as a medical instrument so as to be capable of attaching said illumination device to said another item.

8. An illumination device according to claim 6 wherein said cradle includes a base, said base having an adhesive thereon for attaching said base to a surface.

9. An illumination device according to claim 1, further comprising a retractor, said retractor having a base portion configured to be removably mountable on said housing and a projecting portion extending from said base portion adjacent to said boom.

10. An illumination device according to claim 1, further comprising a suction device, said suction device including a duct having an inlet and an outlet, said outlet being connectable to a source of suction for drawing fluid into said inlet from an area illuminated by said light source, said suction device having a base portion configured to be removably mountable on said housing and a projecting portion extending from said base portion adjacent to said boom.

11. An illumination device according to claim 1, further comprising a heat sink member fixedly attached to said first end of said boom, and in contact with said light source to conduct heat from said light source to said boom.

12. An illumination device according to claim 11, wherein one of said heat sink member and said light source includes registration pins, and the other of said heat sink member and said light source includes notches for receiving said registration pins so as to properly orient said heat sink member and said light source relative to one another.

13. An illumination device according to claim 1, further comprising a timer, wherein said controller is configured to permanently interrupt the flow of electricity to said light source thereby preventing further use of said illumination device after a predetermined time duration has elapsed.

14. An illumination device according to claim 6, wherein said cradle has retaining elements for cooperating with said housing to hold said housing to said cradle.

15. An illumination device according to claim 14 wherein said housing includes a slot, and said retaining elements include a tab configured to interference fit into said slot for holding said housing to said cradle.

16. An illumination device according to claim 1 in combination with a container for holding said illumination device therein, wherein said container comprises an arming pin attached to said container, where upon removal of said illumination device from said container effects removal of said arming pin from between electrical contacts within said illumination device to permit a flow of electricity to said controller.

17. An illumination device according to claim 8, wherein said adhesive is covered by a release member, and said release includes another adhesive on the side of said release member opposite said first adhesive and which is attachable to a surface such that removal of said cradle base from said surface causes said release to remain attached to said surface thereby exposing said first adhesive on said base.

18. A kit, comprising:

a container;

the illumination device of claim 1 within said container; and

at least one cradle within said container, said first cradle shaped to receive and support a portion of said housing therein, said housing being releasably attachable to said cradle.

19. The kit according to claim 18, further comprising a medical instrument such as a retractor or suction device within said container, said instrument having a base portion configured to be removably mountable on said housing and a projecting portion extending from said base portion adjacent to said boom.

20. A kit in accordance with claim 18 further comprising a second cradle shaped to receive and support a portion of said housing therein, said housing being releasably attachable to said second cradle;

and

wherein said first cradle includes a mounting strap attached thereto, said strap being further attachable to another item such as a surgical tool so as to be capable of attaching said illumination device to said another item, and said second cradle includes a base having an adhesive thereon for attaching said base to a surface.
