Rotary endoscope with oblique distal sight

摘要

The endoscope consists of a housing (5) containing a probe (45) and a rotary eyepiece (67) with a trapezoid prism to correct image inversion from the transmitting prism at the distal end. The proximal end of the endoscope probe and the eyepiece are coupled by a transmission system which allows for the transmission of movements to the eyepiece from the rotation of the endoscope probe and axial movement of the eyepiece independent of the probe. The proximal end of the rotary probe (45) inside the housing has two diametrically opposite rectangular lugs (34), and the distal end of the eyepiece has matching recesses.
