Abstract
A robotic surgical system includes an access port having a plurality of sensors incorporated therein and a surgical instrument having an end effector for use with, and connection to a robot arm. The sensors measure a loading parameter between tissue and the access port when the shaft is inserted through the access port. The sensors wirelessly transmit signals indicative of the loading parameter to a processing unit. The estimated loads at the tip of the end effector of the surgical instrument are provided in real-time to a haptic feedback interface for communicating haptic feedback to a user. The haptic feedback increases or decreases in intensity in response to a specific event, occurrence, or operational characteristic related to the estimated loads.
