The panel made of OLED material powered by a small battery can be placed into a surgical cavity for illuminating portions of the anatomy from within the cavity. The housing for the panel includes a malleable material that permits the panel to be bent or otherwise configured to a shape that will best accommodate the organs and other tissue defining the cavity. The battery, switch, electronics and OLED material are a housed in a single unit for ease of use during a procedure and disposal afterward. ## Claims ### Claim 1 A medical lighting apparatus comprising: a. a light emitting panel including an organic light emitting diode (OLED) material sized for insertion into an anatomical surgical cavity to illuminate the surgical field independently of any retractor blade or other surgical instrument; b. the OLED material being made of a flexible material of less than 5 mm in thickness to permit it to be bent into the desired shape for the surgeon's needs; c. a housing for the panel made of malleable material that permits the panel to retain the form into which it can be bent; d. a battery having a thickness of 5 mm or less and at least one of a width and length dimension of 22 mm or less; e. the battery being electrically connected to the OLED material; f. a switch for controlling power from the battery to the OLED material; and g. the housing having a thickness of between 5-10 mm. ### Claim 2 (depends on 1) The apparatus according to claim 1 wherein the battery has a diameter of 22 mm and thickness of 3.2 mm. ### Claim 3 (depends on 1) The apparatus according to claim 1 wherein the weight of the battery ranges between 1.5 g to 10 g. ### Claim 4 (depends on 1) The apparatus according to claim 1 wherein the weight of the switch ranges between 3 g and 10 g. ### Claim 5 (depends on 1) The apparatus according to claim 1 wherein the switch is integral with the housing for the panel. ### Claim 6 (depends on 1) The apparatus according to claim 1 wherein the switch is separable from the housing and operable remotely therefrom. ### Claim 7 (depends on 6) The apparatus according to claim 6 wherein the switch is wirelessly connected to said panel for activating the OLED material between an “on” and an “off” position. ### Claim 8 (depends on 6) The apparatus according to claim 6 wherein the switch includes a driver circuit that permits dimming of the light generated by the OLED material. ### Claim 9 (depends on 1) The apparatus according to claim 1 wherein the battery is operable between 3 and 6 volts. ### Claim 10 A medical lighting apparatus comprising: a. a light emitting panel including an organic light emitting diode (OLED) material sized for insertion into an anatomical surgical cavity to illuminate the surgical field independently of any retractor blade or other surgical instrument, the panel being rectangular in shape; b. the OLED material being made of a flexible material of less than 3 mm in thickness to permit it to be bent into the desired shape for the surgeon's needs; c. a housing for the lighting panel made of a malleable material that permits the panel to retain the form into which it can be bent, the housing including a tubular ductile material surrounding the panel; d. a battery having a thickness of 5 mm or less and at least one of a width and length dimension of 22 mm or less; e. the battery being electrically connected to the OLED material; f. a switch for controlling power from battery to the OLED material; and g. the panel, the housing, the switch and the battery being integrated into a single unit for insertion into a surgical cavity. ### Claim 11 (depends on 10) The apparatus according to claim 10 wherein the single unit is made of sterilizable material. ### Claim 12 (depends on 10) The apparatus according to claim 10 further comprising a securing mechanism for securing the panel to a surface adjacent the surgical cavity. ### Claim 13 (depends on 10) The apparatus according to claim 10 wherein the battery is wirelessly connected to the panel. ### Claim 14 A medical lighting apparatus comprising: a. A light emitting panel including an organic light emitting diode (OLED) material sized for insertion into an anatomical surgical cavity to illuminate the surgical field independently of any retractor blade or other surgical instrument; b. the OLED material being made of a flexible material to permit it to be bent into the desired shape for the surgeon's needs; c. the panel including a housing made of malleable material that permits the panel to retain the form into which it was bent; d. the housing having a thickness of 10 mm or less; e. the housing surrounding the perimeter of the OLED material; f. a battery electrically connected to the OLED material; g. a switch for controlling power from the battery to the OLED material; h. the battery and the switch having a thickness of 10 mm or less; and i. the light emitting panel, the battery and the switch being packaged in a sterile container. ### Claim 15 (depends on 14) The apparatus according to claim 14 wherein said malleable material affixed to the perimeter of the panel includes an arcuate cross-sectional portion on its outermost perimeter. ### Claim 16 (depends on 14) The medical lighting apparatus according to claim 14 wherein the panel, the OLED material, the battery, and the switch and housing are combined in a single unit.
