Abstract:
A rotary endoscope with a deflected distal sight, the endoscope comprising:a cylindrical handle; an endoscopic probe, comprising a distal optical deflector, which introduces one-way inversion of an image of an object observed through a distal lateral lens port, a lens, and an optical image conveying system, the proximal end of which, accommodated in the distal part of the handle, conveys the image of the object observed along an optical axis to an ocular lens; an adjustment device controlled by an outer ring displaces longitudinally along the optical axis, the ocular lens, which is accommodated in the median part of the handle; a one-way image rectifier accommodated in the proximal part of the handle, and positioned radially, such as to compensate for the one-way image inversion introduced by the distal deflector; a rotation device controlled by an outer ring rotates simultaneously and synchronously around the optical axis, the distal deflector, and the proximal rectifier; the endoscope being characterized in that: the proximal end of the endoscopic probe is integral with the distal end of a cylindrical tube, which is accommodated such as to rotate in the cylindrical handle; the rectifier is integral in the proximal end of the cylindrical tube; and the ocular lens is secured in a cylindrical mount, which is accommodated such as to slide but not rotate, inside the median part of the cylindrical tube.
