The present invention discloses an electrosurgical device comprising an end effector, a cutting member and an electromechanical driver. The end effector includes a pair of jaws that grip tissue. The jaws include electrodes that deliver radio frequency energy to the clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical drive drives the cutting member. A control module controls the electromechanical driver and adjusts the delivery of RF energy to the electrodes based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input structure in accordance with the load experienced by the cutting member. The device can alert the user when the exterior of the end effector accidentally touches tissue to avoid accidental burning of the tissue. The device may include a removable battery pack to power the electromechanical drive and electrodes. |
