A surgical instrument is operable to deploy an anastomotic ring device.
The instrument comprises a ring deployment mechanism configured to
receive and deploy the anastomotic ring through an actuating force. The
instrument further comprises an electroactive polymer that is configured
to receive voltage from a power source. The electroactive polymer is
configured to convert the voltage to a mechanical actuating force. The
electroactive polymer is further configured to apply the actuating force
to the ring deployment mechanism to deploy the anastomotic ring.
