Abstract: An external endoscope light source system includes light emitting diodes for providing a light output to an endoscope. The light is provided to a fiber optic cable for transmission to the endoscope. A fiber optic receives a portion of the light output and provides the output to a color sensor for sensing color values. The color values are provided to a controller that adjusts power to the various LEDs to provide a white light output. Instead of a color sensor in the light source, the light source can receive a white balance signal from a video camera provided for an endoscope. The white balance signal varies intensity of light output from each of the LEDs to obtain a white light output. The camera also provides shutter speed of a camera image sensor to the light source. The shutter speed is used to pulse or modulate the light output only when the shutter of the camera is open. By modulating the light output by the light source, the amount of heat generated by the light source is minimized.

Abstract: A wireless foot control apparatus allows an operator to control multiple medical devices during an endoscopic medical procedure. The apparatus comprises a control console with controls designed for foot operation to control various medical devices. The controls include one or more foot pedals and foot switches to control the devices, including a selection switch to allow selection of the device to be controlled at a particular time. The console transmits signals over a wireless medium, to cause a remote receiver unit to select the device to be controlled and to control the selected device over a wired medium, in response to operation of the foot controls. The console may include a rechargeable battery, which may be sealed within the console's housing and charged inductively when the console is placed in a charging station. The receiver unit and the charging station can be separate units or integrated within a single housing.

Abstract: An endoscopic system having a light source that can operate in two modes is provided. The first mode provides a white light to an endoscope to transmit the light to a surgical site or other object, the reflection of which can be received by the endoscope and for the process. The second mode of the light source provides infrared excitation light and light in the blue and green wavelength spectra to an endoscope to transmit the light to an object such as a surgical site. The blue and green reflected light, as well as light from excitation markers, which is an infrared light at a different wavelength than the excitation infrared light, is received by the endoscope and further processed.

Abstract: A system and method for wirelessly transmitting a video image signal from an endoscopic camera to a receiver or control unit for storage and/or display on a video monitor. Use of a frame-specific, variable compression algorithm capable of progressively encoding a data stream provides for a better performing and higher quality wireless endoscopic camera system capable of generating images at varying resolutions. Use of a short-range, high-performance wireless technology, such as Ultrawideband (UWB), improves the performance capabilities of the system, while minimizing power consumption and extending battery life. Implementations of error correcting codes, as well as the use of multiple transmitting and receiving antennas, further improve the fidelity of the wireless communication.

Abstract: A method and apparatus for wirelessly synchronizing operation of an image sensor of an endoscopic video camera unit having a wireless transmitter with operation of a portable endoscopic light source unit includes transmitting a message packet with a target camera shutter period, light source target phase/trigger time/OFF time and light source target ON time to the light source unit. The light source unit controls the start time and the ON time for light output by a light source. The video camera unit includes a light detector for detecting the actual light source start time and duration of light output to provide closed-loop feedback. A camera controller ensures synchronization between the shutter period of the image sensor and actual operation of the light source based on the actual phase and actual ON time sensed by the light detector and the previously communicated target phase/trigger time/OFF time and target ON time.
