Head cursor control interface for an automated endoscope system for optimal positioning

Abstract

An interface that allows a surgeon to remotely control surgical devices and conditions of an operation room. The surgeon views a video image that is displayed by a monitor. The monitor may be coupled to a video device such as a laparoscopic camera that is attached to the end of an endoscope. Static graphic images and a dynamic graphic cursor are overlayed onto the video image. The graphic cursor has a pixel location on the monitor which corresponds to a spatial location of a pointer signal. The pointer signal is transmitted by a transmitter worn on the head of the surgeon. The pointer signal may be a laser which is directed to a screen that is located adjacent to a detection camera. The surgeon may move the graphic cursor relative to the video image by tilting his head and varying the spatial location of the pointer signal. The interface may have a controller which generates output signals in response to the movement of the pointer signal. The output signals may move a robotic arm which controls the position of the endoscope. The controller may also generate command signals when the graphic cursor is moved into a static graphic image. The command may vary a condition of the operating room such as the position of the operating table.
