A wire-operated selective compliance mobile platform (), in particular for endoscopic surgery devices, obtains a perfect and precise mobility and thus it allows to handle, in the most effective way, the supported instruments, and comprises a mobile surface (), a connecting base () apt to be connected to a flexible tubular duct () for endoscopic uses, a plurality of supporting elements (), apt to permit the motion of said mobile surface () relative to said base (), characterized in that said supporting elements () have at least a selective compliance turning pair () and a number of joints () so as to provide a predetermined number of degrees of freedom to said platform (), neither determining any over-constraining, nor forcing the system to be deformed in unselected directions, each supporting element () being operated by moving means () so as to move said mobile surface ().

A selective compliance hinge, apt to define a turning pair with a default axis of rotation (A), allows to obtain a selective compliance turning pair, hence with the advantages typical of such applications but providing the best precision and movement repeatability, and comprises a connecting element () compliant between a first and a second body (), and characterized by that each of said bodies () has a first and a second extension (), respectively, said extensions () comprising respective surfaces () conjugate therebetween, so that said surfaces () slide one relative the other remaining adjacent therebetween and defining a rotary motion taking place substantially about said default axis of rotation (A).
