LED lighting apparatus and method of using same for illumination of a body cavity
First Claim
1. An apparatus that is for partial insertion through an incision in the outer skin surface on a torso of the body to an internal body cavity that has surrounding internal body tissue and provides internal chandelier lighting to the internal body cavity for use during a surgical procedure without damaging tissue within the body cavity, the apparatus comprising:
- a sterile exterior housing having a tip end and a back end, wherein the tip end allows light to pass therethrough;
a plurality of switched LED'"'"'s disposed within the sterile exterior housing at the tip end that are operated to enable placement of the tip end against internal body tissue for at least 30 minutes, the plurality of switched LED'"'"'s including at least three LED'"'"'s having normal beams that are different from one another and are operated at less than a maximum operating point to ensure a substantially white light and provide chandelier lighting, wherein the chandelier lighting provided by the plurality of switched LED'"'"'s is at least 10 Candelas of substantially uniform illumination over at least a radially increasing half sphere around the tip end such that the substantially uniform illumination is sufficient for field of vision within the internal body cavity that is both magnified and non-magnified; and
a power source that provided power to the plurality of switched LED'"'"'s disposed within the sterile exterior housing,wherein the sterile exterior housing, the plurality of LED'"'"'s and the power source form a unit, and wherein the unit is adapted to be self-supporting at an area of the exterior outer housing that widens between the tip end and the back end, and wherein the self-support is assisted by the unit being internally weighted to allow the exterior outer housing to balance at the area when the area rests upon the outer skin surface at the incision and the tip end is inserted through the incision.

Abstract
The present invention provides an LED lighting apparatus and a method of using the same for illumination of a body cavity. In one aspect, the present invention provides a method of surgery in which one incision is made for hands and surgical instruments, and another incision is made for insertion of an LED lighting device. Both incisions open into the same cavity, and the lighting device provides continuous internal lighting to the body cavity where the operation is occurring. In another aspect, a method and apparatus are described that provide internal chandelier lighting to an internal body cavity using a plurality of switched LED'"'"'s for surgical without damaging tissue within the body cavity.
