DRIVE TRAIN CONTROL ARRANGEMENTS FOR MODULAR SURGICAL INSTRUMENTS
First Claim
1. A surgical instrument, comprising:
- an end effector;
a shaft extending proximally from the end effector;
a firing assembly configured to fire a plurality of staples;
an articulation assembly configured to articulate the end effector relative to the shaft;
a locking member movable between a locked configuration and an unlocked configuration; and
a housing extending proximally from the shaft, wherein the housing is removably couplable to the shaft when the locking member is in the unlocked configuration, the housing comprising;
a motor configured to drive at least one of the firing assembly and the articulation assembly; and
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.

Abstract
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.
