Abstract

The instrument has a working insert which may be inserted into a coupling housing sitting on the proximal side on an instrument shank and is releasably connectable to said housing and which includes a seal, carried by a carrier, which has at least one elastic socket for the sealed leading-through of auxiliary instruments and which seals a first axial passage formed in the carrier with respect to the coupling housing. The seal consists of a base body which is located in a holder and which with each socket forms a one-piece component of elastic material, and the holder includes an arrangement for the releasable connection to the carrier.
