A surgical system having all of the various pneumatic control sub-systems or sub-manifolds integrally mounted on a common primary manifold. The various required control mechanisms such as valves are likewise integrally mounted to the common manifold and to the sub-manifolds. Within any or all of the sub-manifolds or primary manifolds, volumes of material not necessary for the operation of the manifold are carved or pocketed out and used to form integral accumulators for storing extra pressurized air. The volume of the accumulator can vary according to the pressurized air requirement of the particular manifold, or the overall pneumatic system.
