Abstract
The invention is a sideways looking video endoscope which offers a rigid endoscope tube. The optical system has one prism, and an image sensor located behind the optical system, provided on the distal end of the endoscope shaft. On the proximal end of the shaft, a knurled wheel is arranged so as to rotate freely. This wheel is provided with permanent magnets that are arranged at identical angular separations, and associated with Hall sensors located on the front face of the tool holder. The angular position of the rotatable wheel can thus be detected by means of the Hall sensors together with an electronic system that evaluates the signals, and displayed on a monitor. By turning the rotating wheel, the image can be rotated, thus correcting the image position when the endoscope is rotated, such that the viewing direction corresponds to the actual position of the object.
