Abstract
Rotary endoscope has a deflected distal sight. The endoscope includes a cylindrical handle. An endoscopic probe includes 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 endoscopic probe has a proximal end which is accommodated in a distal part of the cylindrical handle, and is adapted to convey the image of the object observed along an optical axis to an ocular lens. An adjustment device moves the ocular lens in a controlled manner by an outer ring. The ocular lens is arranged in a median part of the cylindrical handle and is movable longitudinally along the optical axis. A one-way image rectifier is arranged in a proximal part of the cylindrical handle. The one-way image rectifier compensates for the one-way image inversion introduced by the distal optical deflector. A rotation device is movable in a controlled manner by an outer ring. The rotating device rotates, simultaneously and synchronously about the optical axis, each of the distal deflector and the one-way image rectifier. The proximal end of the endoscopic probe is coupled to the distal end of a cylindrical tube. Each of the endoscopic probe and the cylindrical tube is rotatable with respect to the cylindrical handle. The one-way image rectifier is arranged adjacent the proximal end of the cylindrical tube. The ocular lens is mounted in a cylindrical mount which is slidably and non-rotatably mounted in the median part of the cylindrical tube.
