Abstract: A system for a medical device that can operate multiple actuated implements with sophisticated and individual motion profiles using a single user actuator. The system has a handle having a pair of slots for each implement and an actuator positioned in the handle for movement between a first position and a second position that has a groove for each implement. Each implement is coupled to the handle a barrel that is captured in the pair of slots and driven by the groove of the actuator. The shape of the pair of slots and the corresponding groove combine to provide a motion profile for the implement that is independent from any other implement having its own pair of slots and groove. Multiple implements may thus be driven simultaneously and can have complex and coordinated movement based on user operation of the single actuator.
