Abstract:
1. A method comprising: illuminating a target area with a medical instrument including an illumination system comprising one or more light sources; determining a state of activity according to processing of signals from one or more image sensors; adjusting the illumination system between a first illumination mode and a second illumination mode based on an input into the illumination system; reducing power to the one or more light sources after processing the signals from the image sensor and determining the state of activity to be an output indicative of inactivity; determining power to the illumination system using a power controller; configuring the medical instrument to sense a predetermined change in power to the one or more light sources based on a change in temperature; configuring the medical instrument to sense a change of scene or a change in brightness, and wherein the method includes a step of changing power to the one or more light sources based on a change in scene, a lack of change in scene, or a change in brightness; wherein the method includes a step of controlling a temperature of the handle of the medical instrument below a predetermined maximum temperature by controlling power to the one or more light sources based on the input from the temperature sensor mounted in the handle; wherein the input into the illumination system is the state of activity; and wherein a temperature sensor is mounted in a handle of the medical instrument and is a back-up to the input into the illumination system for the state of activity.
