Abstract
Abstract A surgical lighting system provides remote control of surgical lights. The parameters (for example, illumination levels and beam direction) of the lights are remotely controlled, thereby eliminating the need for surgical personnel to manipulate the lights. The individual light instruments that are employed with the system are enclosed in the housing that isolates the instruments from the surgical suite, thereby avoiding contamination. A sequence of lighting parameters as required for a particular surgical procedure may be pre-recorded and played back by the processor that controls the light instrument parameters.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
A lighting system, comprising: a light instrument movable into any of a plurality of positions for illuminating any of a plurality of sites; a housing, the light instrument being mounted within the housing and movable therein relative to the housing, the housing enclosing the light instrument and including a transparent portion through which light from the light instrument propagates; ventilation means for moving air into and out of the housing; and remote control means for controlling movement of the light instrument by sending control signals thereto.
Claim 2
Dependent Claim
86 words
A lighting system, comprising: a light instrument movable into any of a plurality of positions for illuminating any of a plurality of sites; a housing, the light instrument being mounted within the housing and movable therein relative to the housing, the housing enclosing the light instrument and including a transparent portion through which light from the light instrument propagates; ventilation means for moving air into and out of the housing; and remote control means for controlling movement of the light instrument by sending control signals thereto.
Claim 3
Dependent Claim
26 words
The system of claim 1 further comprising at least one reserve light mounted within the housing and operable for illuminating a site outside of the housing.
Claim 4
Dependent Claim
26 words
The system of claim 2 further comprising emergency means connected to the light instrument for sensing failure of the instrument and for operating the reserve light.
Claim 5
Dependent Claim
22 words
The system of claim 1 further comprising ventilation means for maintaining the air pressure within the housing at less than ambient pressure.
Claim 6
Dependent Claim
23 words
The system of claim 1 further comprising a metering means for monitoring and displaying the running time that the light instrument is illuminated.
Claim 7
Dependent Claim
35 words
The system of claim 1 wherein the remote control means includes programming means for storing a plurality of control signals and for sending the stored control signals to the light instrument in a preselected sequence.
Claim 8
Dependent Claim
39 words
The system of claim 1 wherein the remote control means includes a portable control unit positionable remote from the light fixture and configured for manipulation by a user at a site for changing the position of the light instrument
Claim 9
Dependent Claim
57 words
The system of claim 1 wherein the light instrument includes a source and a reflector, the reflector reflecting light from the source, the instrument including filtering means for reducing ultraviolet and infrared radiation reflected by the reflector the filtering means including an ultraviolet radiation filter mounted to the instrument to filter ultraviolet radiation reflected by the reflector.
Claim 10
Independent Claim
82 words
A method of illuminating a surgical suite, comprising the steps of: mounting above the surgical suite in a chamber that is sealed from the suite a light instrument that is operable by control signals for movement into any of a plurality of positions for illuminating any of a plurality of sites with any of a plurality of illumination parameters; ventilating the chamber by moving air therethrough; and sending from a remote location to the light instrument control signals for operating the instrument.
Claim 11
Independent Claim
82 words
A method of illuminating a surgical suite, comprising the steps of: mounting above the surgical suite in a chamber that is sealed from the suite a light instrument that is operable by control signals for movement into any of a plurality of positions for illuminating any of a plurality of sites with any of a plurality of illumination parameters; ventilating the chamber by moving air therethrough; and sending from a remote location to the light instrument control signals for operating the instrument.
Claim 12
Dependent Claim
24 words
The method of claim 9 wherein the ventilating step includes the step of maintaining within the chamber air pressure less than ambient air pressure.
Claim 13
Dependent Claim
34 words
The method of claim 9 further comprising the step of storing a plurality of control signals representative of preselected light instrument positions and parameters; and sending the stored control signals in a predetermined sequence.
