MULTIPLE MOTOR CONTROL FOR POWERED MEDICAL DEVICE

摘要

A surgical instrument includes an end effector with a first jaw and a second jaw. The instrument also includes a first drive assembly, a first motor coupled to the first drive assembly, a second drive assembly, a second motor coupled to the second drive assembly, a control module, and a closure trigger. The first motor is operable to motivate the first drive assembly, and the second motor is operable to motivate the second drive assembly. The control module is operably couplable to the first motor and the second motor. The closure trigger is movable during a closure stroke to transition the end effector to the approximated configuration, and to transition the control module from operable engagement with the first motor to operable engagement with the second motor.
