摘要：
Methods and devices are provided for retracting a cutting assembly in the event of a failure on a motorized electrosurgical device. As an example, a surgical device is provided that includes a handle portion with an elongate shaft extending distally that has first and second jaws configured to engage tissue therebetween. A cutting assembly cuts tissue engaged between the first and second jaws. A drive shaft extends from the handle through the elongate shaft and moves the cutting assembly. A motorized gear assembly moves the drive shaft. The drive shaft is movable between a first position in which the drive shaft is engaged with the motorized gear assembly such that actuation of the motorized gear assembly drives the drive shaft, and a second position in which the drive shaft is disengaged from the motorized gear assembly such that the drive shaft can move independent of the gear assembly.
