A method and system for use in surgery, which includes a grasper having a jaw, and a grasper housing having a proximal end and distal end and defining a docking opening, and a tool having a tool housing having a proximal end, a distal end and defining an inner surface, and a robotic device operably coupled to the proximal end of the grasper housing, and configured to actuate the jaw of the grasper. The tool housing having an operative assembly at the distal end of the tool housing, and the tool housing defining a docking assembly at the proximal end of the tool housing. The operative assembly having a fulcrum operably coupled to the tool housing, a first lever operably connected to the fulcrum, an instrument operably coupled to the first lever, and an actuator operably coupled to the tool housing and the first lever.
