Abstract

A medical shaft-type instrument includes an instrument head for applying clamps, the instrument head connectable via an instrument shaft to an instrument handle for actuating the instrument head. The instrument also includes a clip magazine having a housing, in which magazine a plurality of clamps are bunkered at a predetermined storage position spacing to each other according to the storage principle. All of the clamps can be moved forward by one storage position by a reciprocating transport and entraining rail within the scope of a single delivery stroke. The transport and entraining rail has one clamp entraining element per clamp. The relative distance of the individual clamp entraining elements differs from the respective storage position distances of the clamps in such a way that the entrainment of the bunkered clamps is carried out within the scope of one single delivery stroke in a clocked way.
