A surgical illumination device for illuminating a surgical field to provide enhanced visual perception of a tissue during a medical procedure. The surgical illumination device includes a surgical light and a tunable light controller. The surgical light includes a first light source providing a first wavelength of light, a second light source providing a second wavelength of light, and a combiner receiving and combining the first and second wavelengths of light. The tunable light controller includes a database and a tuning device. The database is organized by medical procedure and stores an identification of the medical procedure and at least one pre-programmed color setting for each medical procedure. The preprogrammed color setting is adapted to facilitate a first assigned illumination. The tuning device communicates with the database. The tuning device retrieves the pre-programmed color setting from the database and controls the first light source and the second light source such that the first wavelength and the second wavelength combine to provide the first assigned illumination.

A lighting control system suitable for a surgical lighting device. The lighting control system includes circuitry that compensates for the effects of temperature changes in a lighting device, and that compensates for forward voltage variations among LED lighting modules to provide substantially uniform light output.

A surgical illumination system, according to the present disclosure may include one or more illumination elements mounted on or in a collar body or surgical retractor pin that may also include control electronics. The surgical illumination system affords controllable direct illumination of a deep cavity surgical site and may be moved independent of any surgeon or surgical instrument. The collar body or pin provides heat conductivity to remove heat generated by the illumination elements. The collar body is adapted for engagement of Steinman style surgical retractor pins and to afford optimal heat transfer to the retractor pin. Energy for the illumination elements may be provided by batteries or other suitable source through a cable or wireless link.

A surgical light system (10) includes a lighthead (44) coupled to a suspension arm (41′) adapted for mounting to a surface (14) of a surgical room. A bulb (130) is disposed in the lighthead. A processor (120) in the lighthead is operatively coupled with the bulb for controlling an intensity of light of the bulb and is adapted to generate a lighthead status signal representative of a first status of the lighthead. A control apparatus (32, 34) is in operative communication with the processor (120) in the lighthead. The control apparatus receives the lighthead status signal and selects a set of control algorithms from among a group of algorithms based on the lighthead status signal for controlling the lighthead. The lighthead status signal includes information regarding a size of the lighthead, an intensity of light from the bulb, a condition of the bulb, a level of current applied to the bulb, a level of current applied to the bulb, a level of voltage applied to the bulb, an internal temperature of the lighthead, and the presence of one or more of a video camera, a surgical task light, and a controllable ambient light. A human-readable display device (160) is provided for displaying information relating to the lighthead status signal. Several levels of redundancy are provided in the control system to minimize the potential loss of control due to failures. In that regard, the lightheads are operable when the control apparatus (32, 34) fails.

An adaptive shadow control system that compensates for blockage of one lighthead of a surgical lighting system by increasing the light output from one or more other lightheads of the lighting system. The system also includes control logic for automatic enablement/disablement of adaptive shadow control by detecting whether there is blockage of a lighthead and whether the respective light beams of a plurality of lightheads are being aggregated to form a single aggregated co-illumination light pattern at a work area.

The present invention provides a surgical lighting system with an image-recording function mainly comprising a surgical light set and a flexible tube-shaped video camera connected to the surgical light set. The surgical light set comprises a fixed base; a rotary arm set pivoted to the fixed base, the rotary arm set comprising at least one rotary arm; and a surgical light connected to one rotary arm of the rotary arm set.

The invention relates to a general surgery three-dimensional micrography camera shooting presentation device which is formed by a 3D high-definition digital video, a 3D high-definition liquid crystal displayer and an adjusting support. The 3D high-definition digital video is a small integrated 3D high-definition digital video, a micrography adapter, a micrography pick-up lens and a focus light source are additionally arranged in front of an original lens of the small integrated 3D high-definition digital video, and the small integrated 3D high-definition digital video is fixed by the bed side type, suspension type or floor stand type adjusting support and connected with the 3D high-definition liquid crystal displayer. The micrography pick-up lens is composed of a single lens or a plurality of lenses, and the focal length of the micrography pick-up lens is 250mm to 500mm. The focusing light source is a cold light source which connected through light fibers or an LED light source, a focusing lens is additionally arranged at the front end of the focusing light source, and the optical axis focus of the focusing light source is identical with the focus of the 3D micrography pick-up lens. The general surgery three-dimensional micrography camera shooting presentation device is small and light, has the functions of surgery lighting, 3D real-time high-definition camera shooting, videotaping, recording, displaying, image transmitting and the like, and is suitable for multidiscipline micrography surgeries and general open surgeries in surgery systems.
