Abstract
A surgical tool system including a laparoscopic surgical tool for heating, ablating, sealing, and/or dissecting tissue, a control system for monitoring impedance of the tissue during treatment thereof, and a tactile feedback system integrated onto a handle of the tool that generates relevant feedback from the control system in at least the form of haptic effects to the user. The tactile feedback alerts the tool user of changes in tissue properties, i.e., when the impedance of the tissue indicates that the treatment procedure is complete. In addition, the tactile feedback provided may supply information relating to the operating status of the control system to the user.
