Patent attributes
An accessory drive device includes a housing, a fluid inlet, a fluid outlet, a drive mechanism, and an output drive member. The output drive member may be driven by the drive mechanism and engage with an input drive member on a transmission mechanism of a surgical instrument. The drive mechanism may be configured to be driven by a motive force produced by fluid flowing through the housing from the inlet to the outlet, with the fluid being delivered by a fluid source of a reprocessing device. A portable, accessory drive device for a surgical instrument includes a portable housing to be removably coupled to a transmission mechanism of an instrument and a drive mechanism to drive an input drive member of the transmission mechanism. A method of reprocessing a surgical instrument includes converting a force associated with a flow of fluid for reprocessing to drive an instrument input drive member.
