Abstract
A surgical method and a control system is provided. The surgical method and the control system can advantageously be used in a minimally invasive surgical apparatus. The method includes generating a desired surgical instrument movement command signal. It further includes comparing the desired surgical instrument movement command signal with at least one preset surgical instrument movement limitation. Should the desired surgical instrument command signal transgress the preset surgical instrument movement limitation, the desired surgical instrument movement command signal is restricted to yield a restricted surgical instrument movement command signal. A surgical instrument is then caused to move in response to the restricted surgical instrument movement command signal. The method further provides for haptic feedback on a master control in response to restriction of the desired surgical instrument movement command signal.
