<p>In order to establish a sterile barrier between a sterile operating environment, including an endoscope (10), and a non-sterile environment including an imaging unit (10), a condom-like sheath (40) is provided in rolled-up form on a coupling device (12). The coupling device (12) has first (108) and second ends (110) adapted to mate the endoscope (10) and the imaging unit (16) respectively. After the coupling device (12) is mated with the imaging unit (10) the sheath (40) can be unrolled to cover the non-sterile imaging unit (10), but leaving the focusing mechanism (48) uncovered.</p> |
