Abstract

The present disclosure provides a surgical instrument including an end effector, a drive member movable to effectuate a motion in said end effector, a motor operable to move the drive member to effectuate the motion in the end effector and a bailout assembly operable to perform a mechanical bailout of the surgical instrument in response to a bailout error. The bailout assembly includes a bailout door, a bailout handle accessible through the bailout door. The bailout handle is operable to move the drive member to effectuate a bailout motion in the end effector. A controller includes a memory and a processor coupled to the memory. The processor is configured to detect the bailout error. The processor is programmed to stop the motor in response to the detection of the bailout error.

Claims9

Dependent claims

A surgical instrument, comprising:

an end effector;
a drive member movable to effectuate a motion in said end effector;
a motor operable to move said drive member to effectuate said motion in said end effector;
and
a bailout assembly operable to perform a mechanical bailout of said surgical instrument in response to a bailout error, said bailout assembly comprising:
a bailout door;
a bailout handle accessible through said bailout door, said bailout handle operable to move said drive member to effectuate a bailout motion in said end effector;
and
a controller, comprising:
a memory;
a processor coupled to said memory, said processor configured to detect said bailout error, wherein said processor is programed to stop said motor in response to said detection of said bailout error;
and
an override mechanism configured to permit a user to restart said motor when said bailout error remains.
