SURGICAL INSTRUMENT SYSTEM INCLUDING REPLACEABLE END EFFECTORS |
摘要 |
A surgical instrument system that includes a housing and a rotatable drive shaft, a motor operably coupled to the drive shaft, and a plurality of replaceable end effectors that can be connected to the housing. Each replaceable end effector includes a drive screw that is turned a fixed number of revolutions by the motor-driven rotatable drive shaft when the end effector is connected to the housing. Each end effector further comprises a firing member operably coupled with the drive screw of the end effector. The drive screw is configured to displace the firing member over a firing length as a result of the fixed number of revolutions. In certain embodiments, each replaceable end effector can include a drive screw with a thread pitch set to the firing length divided by the fixed number of revolutions. |
