Publication number: 20120116379Abstract: An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates 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 feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.Type: ApplicationFiled: June 2, 2011Publication date: May 10, 2012Inventors: David C.
