Abstract: The sample taker comprises a hollow shank with a scoop fixedly connected at its distal end, a handling means provided at the proximal end of the 20 hollow shank and an actuation mechanism. An actuation rod is axially movable in the hollow shank and connectable to the actuation mechanism. A covering is allocated in the trough of the scoop. The covering is fastened to a distal end of the actuation rod and displaceable forwards and backwards.

Abstract: The medical endoscope includes a hollow shank for leading through an operating instrument and a housing which may be detachably coupled to the hollow shank. An optical system includes a shank body with a light guide and an image guide in its inside, wherein the shank body may be inserted eccentrically into the hollow shank. A plurality of hollow shanks is provided, each hollow shank having a coupling which mates with the housing and a tube having an inner wall with a diameter which is different from the inner diameter of the other tubes. The shank body with its light guide and image guide is crescent-shaped in cross section. The housing is provided with a rinsing connection union for supplying and discharging rinsing fluid through the ensoscope.

Abstract: The sample taker comprises a hollow shank with a scoop arranged at its distal end, a handling means provided at the proximal end of the hollow shank and with an actuation organ, and an actuation rod axially movable in the hollow shank and connectable to the actuation organ. To the trough of the scoop rigidly arranged on the hollow shank there is allocated a covering which is displaceable forwards and backwards and which is distally fastened on the actuation rod.
