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.
