Abstract
A camera hand piece (1) with camera housing (12) has a microscopic probe (2) at the front end. On the rear side is a transmission cable (13) which is attached to the camera hand piece (1) with the aid of a coupling nut (14). The camera housing (12) accommodates a microscope housing (11) and includes a motorized drive (4), which drives an eccentric (7) via a gear (6) mounted in a gear housing (9). The eccentric (7) actuates a pusher (5), which moves a connecting rod (8) and thereby displaces a focusing lens system (3) attached to it in the axial direction. This axially displaceable focusing lens system (3) together with a condenser lens system (10), forms a microscopic lens system arranged in a microscope housing (11).
