Abstract

A surgical instrument includes an end effector, a drive assembly operably coupled to the end effector, and a replaceable motor cartridge that includes a motor control circuit board and a motor. The surgical instrument further includes a main control circuit board including a processor and a computer-readable storage device storing program instructions, which when executed by the processor, cause the processor to detect a malfunction of the motor cartridge. The surgical instrument also includes an interface including a mechanical interface portion configured to releasably couple the motor to the drive assembly and an electrical interface portion configured to releasably couple the motor control circuit board to the main control circuit board.

Claims20

Dependent claims

A surgical instrument, comprising:

a jaw assembly, comprising:
a staple cartridge including a plurality of staples;
and
an anvil, wherein at least one of the staple cartridge and the anvil is movable relative to the other one of the staple cartridge and the anvil to capture tissue therebetween;
a firing assembly configured to deploy the plurality of staples into the captured tissue during a firing sequence;
and
a handle, comprising:
an actuator;
and
an interface;
a motor cartridge, wherein the interface is configured to releasably couple the motor cartridge to the handle, wherein the motor cartridge comprises:
an electric motor operably coupled to the firing assembly when the motor cartridge is coupled to the handle;
and
a motor control circuit, wherein the motor control circuit is configured to cause the electric motor to generate at least one rotational motion to motivate the firing assembly to deploy the plurality of staples into the captured tissue in response to actuation of the actuator;
and
a controller, comprising:
a processor;
and
a computer-readable storage device storing program instructions, which when executed by the processor, cause the processor to detect a malfunction of the motor cartridge.
