Abstract

An electric motor drive unit for surgical tools, in which a drive consisting of a motor or motor gear unit is connected to, and electrically insulated from a clutch for the tool by a shaft, and in which the drive as well as current-carrying components are electrically insulated from a housing which accomodates said drive and current-carrying components. To achieve an electrical isolation of the current-carrying components from the tool and the gripping surface of the housing, the shaft, at least over part of its length, is made from an insulating material and runs through a seal which is supported in the housing and sealingly divides the housing into a first and second chamber, of which the first chamber accomodates the drive and the second chamber accomodates the clutch for the tool, said tool being inserted into a distal opening in the housing in the second chamber and connectable to the clutch.
