Patent number: 11064867Abstract: A medical-endoscopic shank instrument includes a hollow shank (2), a distal side housing (8) in the hollow shank, an electronic picture sensor (14) and/or a light located in the housing. The housing is linearly movable to move the picture sensor and/or the light from within an inner lumen (22) of the hollow shank to outside the inner lumen. The housing is displaceable through an opening (20) formed on a peripheral wall of the hollow shank. An inner-lying outer side (26), opposite and away from the opening, is formed on a peripheral wall of the hollow shank and is supported on an elongate carrier (32) which is guided in the hollow shank. The elongate carrier (32) is configured elastically resiliently transverse to longitudinal extensions thereof and extends essentially over a whole length of the hollow shank and is fixed in a region of the proximal end/proximally of the hollow shank.Type: GrantFiled: August 29, 2016Date of Patent: July 20, 2021Assignee: RICHARD WOLF GMBHInventors: Sebastian Frey, Friedrich Hähnle, Eberhard Körner
