Abstract

A lighting device for a surgical operating room comprises a light source for generating visible electromagnetic radiation, at least one light output operatively connected to the light source for emitting and directing the electromagnetic radiation, and an attachment component connected to the light output for removably attaching the light output to a patient. The light output or outlets are mounted to a surgical retractor or, alternatively, to a flexible tube with an adhesive layer for temporarily binding the tube to a skin surface of the patient. The tube is also provided with a form retention element for enabling the tube to be bent to conform to a surgical site. A disposable transparent sheath surrounds the tube or the retractor. Other forms of the lighting device include goosenecks and a frame disposable on the operating table over the patient. In every case, the light source is a cold light source, i.e. spaced from the light output or outlets by an optical fiber.

Claims

1. A method for use in surgery to illuminate a surgical site on a patient, comprising the steps of:

providing a substantially flexible elongate carrier member with at least one linear tubular end segment having a free end and a plurality of colinearly disposed individual light outlets spaced from one another longitudinally along said end segment;

forming at least a portion of said carrier member end segment into an arcuate configuration conformed to said surgical site;

fastening said free end of said end segment to a middle portion of said end segment, said end segment being maintained in said arcuate configuration at least in part by virtue of said step of fastening;

disposing at least said portion of said end segment on the patient so that said portion is at least partially juxtaposed to the surgical site and so that said light outlets can effectively illuminate said surgical site;

surgically operating on organic tissues at said surgical site;

during the step of operating, transmitting electromagnetic radiation from a light source through said carrier member and out through said light outlets to illuminate the surgical site; and

exerting a force on said portion of said end segment to maintain said portion of said end segment in said arcuate configuration during said steps of operating and transmitting.

2. The method defined in claim 1 wherein said step of disposing includes the step of removably affixing said end segment to a skin surface of the patient at said surgical site.

3. The method defined in claim 2 wherein said step of removably affixing includes the step of applying an adhesive strip to said skin surface, said adhesive strip being attached to said portion of said end segment.

4. The method defined in claim 3 wherein said portion of said end segment is maintained in an arcuate configuration at least in part via said adhesive strip.

5. The method defined in claim 1 wherein said portion of said end segment is provided with bendable means attached to said end segment for maintaining said end segment in said arcuate configuration, further comprising the step of deforming said bendable means so that said end segment assumes said arcuate configuration.

6. The method defined in claim 1 wherein means are provided on said end segment for independently varying the orientations of said light outlets, further comprising the step of manually adjusting the orientations of a plurality of said light outlets to differentially vary the direction of light emitted thereby.

7. The method defined in claim 1, further comprising the steps of providing said end segment with a spacer element and attaching said spacer element to said skin surface to control the distance of said end segment from said surgical site.

8. The method defined in claim 1 wherein said end segment is bifurcated along said end segment into two end segment sections each provided with a plurality of spaced light outlets, said step of forming including the step of bending at least a portion of one of said end segment sections into an arcuate shape.

9. The method defined in claim 1 wherein said end segment is further provided with a disposable sheath surrounding said carrier and removably fastened at least indirectly thereto, further comprising the step, implemented after said steps of operating and transmitting, of removing said sheath from said end segment.

10. A method for use in surgery to illuminate a surgical site on a patient, comprising the steps of:

providing a substantially flexible elongate carrier member with at least one linear tubular end segment having a free end and a plurality of colinearly disposed individual light outlets spaced from one another longitudinally along said end segment, means being provided on said end segment for independently varying the orientations of said light outlets;

forming at least a portion of said carrier member end segment into an arcuate configuration conformed to said surgical site;

fastening said free end of said end segment to a middle portion of said end segment, said end segment being maintained in said arcuate configuration at least in part by virtue of said step of fastening;

disposing at least said portion of said end segment on the patient so that said portion is at least partially juxtaposed to the surgical site and so that said light outlets can effectively illuminate said surgical site;

manually adjusting the orientations of a plurality of said light outlets to differentially vary the direction of light emitted thereby;

surgically operating on organic tissues at said surgical site;

during the step of operating, transmitting electromagnetic radiation from a light source through said end segment and out through said light outlets to illuminate the surgical site; and

exerting a force on said portion of said end segment to maintain said portion of said end segment in said arcuate configuration during said steps of operating and transmitting.

11. A method for use in surgery to illuminate a surgical site on a patient, comprising the steps of:

providing a substantially flexible elongate carrier member with at least one linear tubular end segment having a free end and a plurality of colinearly disposed individual light outlets spaced longitudinally from one another along said end segment;

forming at least a portion of said carrier member end segment into an arcuate configuration conformed to said surgical site;

fastening said free end of said end segment to a middle portion of said end segment, said end segment being maintained in said arcuate configuration at least in part by virtue of said step of fastening;

disposing at least said portion of said end segment on the patient so that said portion is at least partially juxtaposed to the surgical site and so that said light outlets can effectively illuminate said surgical site, said step of disposing including the step of adhesively affixing said end segment to a skin surface of the patient at said surgical site;

surgically operating on organic tissues at said surgical site;

during the step of operating, transmitting electromagnetic radiation from a light source through said end segment and out through said light outlets to illuminate the surgical site; and

exerting a force on said portion of said end segment to maintain said portion of said end segment in said arcuate configuration during said steps of operating and transmitting.

12. The method defined in claim 11 wherein said portion of said end segment is maintained in an arcuate configuration at least in part via an adhesive strip on said end segment.
