## Abstract

A lighting system for a surgical operating room comprises a light source for emitting electromagnetic radiation, a support for holding the light source above an operating table in the operating room, the light source being movably mounted to the support, and a drive operatively coupled to the light source for automatically moving the light source relative to the support. An activator or control disposed in proximity to the operating table is operatively connected to the drive for controllably energizing the drive in response to manipulations by a surgeon working at the operating table.

## Claims

### Claim 1

A surgical lighting system, comprising:
light source means for emitting electromagnetic radiation, said light source means including an output portion and a remote light generator and additionally including a plurality of optical fibers connecting said light generator to said output portion;
support means for holding said output portion above an operating table in an operating room, said output portion being movably mounted to said support means;
drive means operatively coupled to said light source means for automatically moving said output portion relative to said support means;
activation means operatively connected to said drive means for controllably energizing said drive means in response to manipulations by a surgeon working at the operating table; and
disposition means operatively linked to said activation means for enabling disposition thereof in proximity to the operating table.

### Claim 2 (depends on 1)

The system defined in claim 1 wherein at least an output portion of said light source means is pivotably and translatably mounted to said track, said drive means including translation means for shifting said output portion of said light source means along said track, said drive means further including rotation means for pivoting said output portion of said light source means relative to said track.

### Claim 3 (depends on 1)

The system defined in claim 1 wherein said track includes a section extending downwardly from said ceiling.

### Claim 4 (depends on 1)

The system defined in claim 1 wherein said activation means includes at least one manual actuator located in proximity to the operating table.

### Claim 5 (depends on 4)

The system defined in claim 4, further comprising a disposable cover connectable to said activation means for protecting said actuator from contamination.

### Claim 6 (depends on 4)

The system defined in claim 4 wherein said disposition means includes mounting means for mounting said actuator to said operating table.

### Claim 7 (depends on 1)

The system defined in claim 1 wherein said activation means includes at least one foot pedal.

### Claim 8 (depends on 1)

The system defined in claim 1, further comprising camera means for taking a photograph, said camera means being movably mounted to said support means, said drive means being operatively connected to said camera means for moving same relative to said support means, said activation means being operable to control motion and operation of said camera means.

### Claim 9 (depends on 1)

The system defined in claim 1 wherein said light source means includes a first generator of light having a first range of frequencies and a first output portion and a second generator of light having a second range of frequencies and a second output portion, said second range of frequencies being different from said first range, said first output portion and said second output portion being independently movable by said drive means in response to manipulations of said activation means.

### Claim 10

A surgical lighting system, comprising:
light source means for emitting electromagnetic radiation;
support means for holding said light source means above an operating table in an operating room, said light source means being movably mounted to said support means, said support means including a track mounted to a ceiling of the operating room, said track having a section extending downwardly from said ceiling;
drive means operatively coupled to said light source means for automatically moving same relative to said support means;
activation means operatively connected to said drive means for controllably energizing said drive means in response to manipulations by a surgeon working at the operating table; and
disposition means operatively linked to said activation means for enabling disposition thereof in proximity to the operating table.

### Claim 11

A surgical lighting system, comprising:
light source means for emitting electromagnetic radiation;
support means for holding said light source means above an operating table in an operating room, said light source means being movably mounted to said support means;
first drive means operatively coupled to said light source means for automatically moving same relative to said support means;
activation means operatively connected to said drive means for controllably energizing said drive means in response to manipulations by a surgeon working at the operating table;
disposition means operatively linked to said activation means for enabling disposition thereof in proximity to the operating table;
camera means for taking a photograph, said camera means being mounted to said support means for motion relative to said support meanas independently of said light source means; and
second drive means different from said first drive means and operatively connected to said camera means for moving same relative to said support means, said activation means being connected to said second drive means for controlling motion and operation of said camera means.

### Claim 12

A lighting system for a surgical operating room, comprising:
light source means for emitting electromagnetic radiation;
support means for holding said light source means above an operating table in the operating room, said light source means being movably mounted to said support means;
drive means operatively coupled to said light source means for automatically moving same relative to said support means;
activation means operatively connected to said drive means for controllably energizing said drive means in response to manipulations by a surgeon working at the operating table, said activation means including at least one manual actuator located in proximity to the operating table; and
disposition means operatively linked to said activation means for enabling disposition thereof in proximity to the operating table, said disposition means including mounting means for mounting said actuator to said operating table.
