A flexible operating room lighting system may be coupled to a wall, ceiling, or fixture of a facility. The lighting system can modularly accommodate multiple illumination arms and incorporate one or more microphone thereon, permitting the vocal control using a processor for hands free operations. The lighting system may include a speaker and a camera to facilitate two-way communications with a user to facilitate demonstrations for individuals undergoing tutelage in the particular facility's profession. The lighting system may employ a stand with wheels to facilitate modularity. Further, a cover with a transparent front end may be provided to be slipped over the lighting system and securing through a cover fastener. By providing each illumination arm with a jack, the illumination arm may be modularly assigned, replaced, sanitized. Thus, the present invention provides reliable sanitary measures while further facilitating a flexible operable device through the illumination arms.

A medical lighting device for illuminating an operating area has an overhead light providing axial illumination and is movably mounted over the operating area and movable manually towards or away from the operating area, and a system for assisting adjustment of a proper lighting position for the overhead light relative to the operating area in such a manner as to position the overhead light at a predetermined distance from the operating area. The system comprises a first light source for generating a first light beam and a second light source for generating a second light beam, the light sources arranged on the overhead light in angularly offset positions so that the first and second light beams converge at a point on the operating area when the predetermined distance is reached, and otherwise when not at that distance the two light beams form two light spots that are disjoint.

A surgical light including a light housing having at least one light source therein and a handle assembly extending from the light housing, with the handle assembly including a knob and a cover. The handle assembly is rotatably connected to the light housing. The cover covers the knob. Engaging the cover in a first mode and rotating the knob alters a first characteristic of light emitted from the at least one light source. Engaging the cover in a second mode and rotating the knob alters a second characteristic of light emitted from the at least one light source.

A system for use during surgical procedures includes a flexible arm having a plurality of ball and socket segments that are interconnected for pivoting relative to one another, a universal adapter coupled with a first end of the flexible arm, and a component adapter coupled with a second end of the flexible arm. The component adapter includes a ball component that forms a snap-fit connection with one of the ball and socket segments. The universal adapter includes a male projection having a free end, an outer surface, external threads provided on the outer surface, a locking flange, and an annular groove formed in the outer surface of the male projection that is located between the locking flange and the external threads. The system has an overhead light connector having a female opening with internal threads. The external threads of the male projection are threaded into the internal threads of the female opening for securing the universal adapter to the overhead light adapter. The overhead light connector has a locking assembly with a locked position that enables the universal adapter to be unthreaded from the overhead light connector and a locked position that prevents the universal adapter from being unthreaded from the overhead light connector.

In a method for controlling a surgical light, the luminance distribution is determined spatially selectively in a measured field and the illuminated field size is adapted to the size of the surgical field while taking account of the luminance distribution.

An electronic endoscope removably connected to a video processor in which a predetermined gamma characteristic is set includes: an image pickup device provided at a distal end of an insertion portion configured to be inserted into a subject, the image pickup device being configured to pick up an optical image of the subject to generate an image pickup signal; a gain circuit configured to amplify the image pickup signal using a predetermined gain parameter; a gamma characteristic recognition circuit configured to recognize the gamma characteristic of the video processor; and a gain adjustment circuit configured to set the gain parameter according to the gamma characteristic.

The invention relates to a handle device for a surgical light, which comprises a handle element, prepared for attachment to a receiving body of the surgical light and forming a handle surface in an exterior region. A voice control module that has at least one acoustic sensor is detachably connected to the handle element. The invention further relates to a surgical light having said handle device.

A handle assembly comprised of a base and a detachable handle that mounts to the base. The base includes integrated electronics, such as switches. The detachable handle includes buttons for activating the switches.

A method and apparatus for improving the optical properties of an LED using a retroreflector element. A light emitting apparatus includes a substrate, at least one light emitting device attached to the substrate and including an outer primary light emitting surface through which substantially all light is emitted, and a retroreflector assembly attached to the substrate. The retroreflector assembly includes a proximal surface adjacent to the substrate, a distal surface spaced away from the substrate, and a retroreflective portion arranged between proximal surface and the distal surface. A distance from the distal surface to the substrate is less than or equal to a distance from the outer primary light emitting surface to the substrate.

A sterile field encroachment indicator apparatus for a surgical lighting system includes one or more encroachment indicators, one or more sensor units, and one or more controllers. The encroachment indicators are configured to indicate encroachment of a predetermined proximity to a surgical lighthead by a foreign entity and contact of the encroaching foreign entity with the surgical lighthead. The surgical lighthead is configured to provide illumination in order to illuminate a surgical environment. The sensor units are positioned in the surgical lighthead, and are configured to sense proximity of the foreign entity to the surgical lighthead and the contact of the encroaching foreign entity with the surgical lighthead. The controllers are configured to control the encroachment indicators based on the sensed proximity of the foreign entity to the surgical lighthead and the sensed contact of the foreign entity with the surgical lighthead.
