A surgical tool system comprising: a surgical tool operable to staple tissue, the tool including a distal portion including a tissue stapling mechanism connected to a handle via a shaft; a sensor coupled to the surgical tool, wherein the sensor is configured to monitor a tissue property; a control system electrically connected to sensor, wherein the control system is adapted to calculate sensor information from signals received from the sensor and to process the sensor information into signal commands; and a feedback system including one or more haptic actuators coupled to the handle and electrically connected to the control system, wherein the control system is adapted to communicate the signal commands to the feedback system and the feedback system is adapted to use the signal commands to generate haptic feedback relating to the sensor information to the handle, wherein the tool system further comprises a cutting element on the distal portion of the tool and a displacement sensor coupled to the cutting element, wherein the feedback system is adapted to generate the haptic feedback depending on a thickness of tissue located within two opposing jaw members (108, 109) coupled to the distal portion of the tool, characterized in that a firing trigger is coupled to the cutting element and the one or more haptic actuators include a kinesthetic actuator coupled to the trigger to enable variable resistance to motion as the haptic feedback, wherein the control system comprises a cartridge-confirmation processor adapted to continuously monitor displacement measurements received from the displacement sensor and to calculate the amount of tissue located within the jaw members (108, 109) from the displacement measurements to determine, if stapling in the current clamped configuration will result in incomplete staple formation, and wherein the cartridge-confirmation processor is further adapted to control the kinesthetic actuator to provide a kinesthetic barrier on the firing trigger to prevent the user from cutting and stapling the tissue, if the amount of tissue within the jaw members (108, 109) is detected as being not appropriate for the stapler cartridge. a surgical tool operable to staple tissue, the tool including a distal portion including a tissue stapling mechanism connected to a handle via a shaft; a sensor coupled to the surgical tool, wherein the sensor is configured to monitor a tissue property; a control system electrically connected to sensor, wherein the control system is adapted to calculate sensor information from signals received from the sensor and to process the sensor information into signal commands; and a feedback system including one or more haptic actuators coupled to the handle and electrically connected to the control system, wherein the control system is adapted to communicate the signal commands to the feedback system and the feedback system is adapted to use the signal commands to generate haptic feedback relating to the sensor information to the handle, wherein the tool system further comprises a cutting element on the distal portion of the tool and a displacement sensor coupled to the cutting element, wherein the feedback system is adapted to generate the haptic feedback depending on a thickness of tissue located within two opposing jaw members (108, 109) coupled to the distal portion of the tool, characterized in that a firing trigger is coupled to the cutting element and the one or more haptic actuators include a kinesthetic actuator coupled to the trigger to enable variable resistance to motion as the haptic feedback, wherein the control system comprises a cartridge-confirmation processor adapted to continuously monitor displacement measurements received from the displacement sensor and to calculate the amount of tissue located within the jaw members (108, 109) from the displacement measurements to determine, if stapling in the current clamped configuration will result in incomplete staple formation, and wherein the cartridge-confirmation processor is further adapted to control the kinesthetic actuator to provide a kinesthetic barrier on the firing trigger to prevent the user from cutting and stapling the tissue, if the amount of tissue within the jaw members (108, 109) is detected as being not appropriate for the stapler cartridge.
