DRIVE TRAIN CONTROL ARRANGEMENTS FOR MODULAR SURGICAL INSTRUMENTS

摘要

A surgical instrument comprises an end effector, a shaft, and a housing extending proximally from the shaft. The surgical instrument includes an articulation assembly configured to articulate the end effector relative to the shaft, a firing assembly configured to fire a plurality of staples, for example, and a locking member movable between a locked configuration and an unlocked configuration. The housing is removably couplable to the shaft when the locking member is in the unlocked configuration and the housing includes a motor configured to drive at least one of the firing assembly and the articulation assembly. The housing also includes a controller in communication with the motor, wherein the controller is configured to activate the motor to reset at least one of the firing assembly and the articulation assembly to a home state when the locking member is moved between the locked configuration and the unlocked configuration.
