Medical therapeutic and/or diagnostic appliance with a sterilizable position sensing attachment

摘要

A medical therapeutic and/or diagnostic appliance includes an arrangement that senses its position and attitude at any given time, and that includes a first sensing unit on the therapeutic and/or diagnostic appliance and a second sensing unit having a fixed location and attitude and arranged to be separated from the first sensing unit by a signal path. The first sensing unit is constructed, for reasons of sterilization and of position sensing, as an attachment that can be detached from the medical therapeutic and/or diagnostic appliance when in use. A coupling device is provided on the medical therapeutic and/or diagnostic appliance for installation of the attachment over a sterilizing sheath surrounding the therapeutic and/or diagnostic appliance.
