Zusammenfassung:A surgical tool includes a stage portion that includes opposing first and second ends, a lead screw and at least one spline that extend between the first and second ends, and a first layer of a carriage movably mounted to the lead screw and the at least one spline. An instrument portion is releasably coupled to the stage portion and includes one or more additional layers of the carriage removably coupled to the first layer, and an elongate shaft extending distally from the one or more additional layers and having an end effector arranged at a distal end of the elongate shaft. The elongate shaft and the end effector penetrate the elevator layer and the first end when the instrument portion is coupled to the stage portion.
