An apparatus for facilitating the mounting of a prosthetic articulation surface to a patient tissue includes an anchoring base including a central fastener aperture extending longitudinally therethrough. The invention extends further to a clamping device set with several sets of exchangeable clamping wedges which have differing distances from the inner to the outer side. A relief valve in the retract circuit directs fluid to tank when fluid pressure increases above a predetermined value. Further, a movable microcomponent suspended above the substrate can be provided.
