Abstract: A shaft and an Albarran, which can be produced in a particularly simple way and can be cleaned particularly easily and time-efficiently. This is achieved by a shaft, or an optical guide tube, and at least one pull wire tube guide being formed in one piece. Owing to this one-piece configuration of the shaft, the long closed pull wire tubes can be eliminated by design. Because of the open construction of the shaft, the shaft can be cleaned particularly easily and time-efficiently. Furthermore, the production of the shaft is particularly straightforward.

Abstract: A shaft and a handheld surgical device with which an optical unit and an access article may be positioned in a simple and reliable way in the shaft. This is achieved in that at least one web, through which an optical unit is directed from the proximal end of the shaft into a bore of a shaft tip, is arranged on an inner wall of a shaft. The at least one web is configured in such a way that the distal tip of the optical unit is guided into the bore when the optical unit is inserted into the shaft, specifically regardless of the shape of the cross section of the shaft.

Abstract: A main body for a manual surgical instrument and a manual surgical instrument, in which tools or access articles can be guided in a straightforward way through a channel, and by means of which at the same time a sufficiently large irrigation flow can be delivered through the channel. This is achieved in that two irrigation bores, which extend through a wall of a main body of a manual surgical instrument, are directed onto an upper region of a cross section of a channel running axially through the main body. In this case, the bores are arranged transversely with respect to the channel.

Abstract: An Albarran deflector can be cleaned or reconditioned particularly thoroughly. This is achieved in that at least one flushing port is arranged on a drive body of the Albarran deflector. During cleaning or reconditioning, a flushing line can be connected to this flushing port. This defined access to the interior of the drive body or gear space allows targeted introduction of the flushing fluid.

Abstract: A shaft and a handheld surgical device have an optimized shape for accommodating an instrument. This is achieved in that a peripheral border of a distal opening of a shaft for a handheld surgical device has a thickening facing outward at least in sections. Cut injuries can be avoided by this thickening due to the rounded borders of the distal opening.
