Abstract
Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device's motor can begin providing power for grasping and/or cutting tissue in response to an output from the device's sensor, the device can adjust power provided by the motor based on whether the device is clamping tissue or is being fired, the device can adjust an amount of power provided by the motor based on an amount of user-applied force to the device's actuator and/or can control drive direction of the motor based on the amount of the force, the device can maintain a force applied to the device, the device can self-shift the motor, and/or the device can adjust an amount of power provided to the device's end effector based on a degree of the end effector's closure.
