Patent Images
1. Endoscopic system comprising:
- at least one endoscope having an objective which generates an image of an area to be observed, at least one video recorder which records the image generated by said objective, at least one instrument, a position-sensing device which detects a position of the at least one instruments, and an assessment and control unit to which an output signal of the video recorder and the position-sensing device are applied and which displays on a monitor the image and symbols representing the position of the instrument, characterized in that said position-sensing device comprises a sensor which also detects orientation of the instrument, and that said assessment and control unit displays symbols which indicate, in addition to the position the orientation of the instrument, and characterized in that a frame is provided which surrounds the display surface of said monitor, and that said assessment and control unit displays the symbols on this frame.

Abstract
An endoscope system includes position sensors which detect not only the position, but also the orientation, of both an endoscope (or endoscopes) and at least one instrument. The endoscope system includes an assessment and control unit which displays symbols which indicate, in addition to the position, the orientation of the instrument or instruments and possibly of the endoscopes relative to a displayed image.
