Abstract
A surgical system includes a power source, a handle housing, a motor, an adapter assembly, an end effector, and a correction unit. The motor is disposed within the handle housing and is in electrical communication with the power source. The adapter assembly is operably coupled to the handle housing and supports an input and an output shaft coupled by the universal joint. The input shaft is in mechanical communication with the motor. The end effector is coupled to the adapter assembly and is selectively articulatable relative to the adapter assembly. The correction unit is in electrical communication with the power source and the motor and is configured to adjust the input shaft speed of the input shaft to maintain a substantially constant output shaft speed of the output shaft as the end effector articulates relative to the adapter assembly.
