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.

A61B 90/00
A61B 17/32

Abstract:

Methods and devices are provided for retracting a cutting assembly in the event of a failure on a motorized electrosurgical device. A surgical device is provided that includes a handle portion with an elongate shaft extending distally therefrom. The elongate shaft has first and second jaws at a distal end, and the jaws are configured to engage tissue. The surgical device also has a cutting assembly configured to cut tissue engaged between the first and second jaws. A drive shaft extends from the handle of the surgical device through the elongate shaft and is coupled to the cutting assembly for moving the cutting assembly. The surgical device has a motorized gear assembly with at least one motor driven gear that is configured to move the drive shaft. The surgical device also has a bailout assembly that is configured to manually move the drive shaft.
