A system to actuate and support surgical diagnostic flexible and orientable instruments of the endoluminal and/or endoscopic type, comprising at least a distal part, a proximal part and a medial part, characterized in that at least the distal part consists of vertebrae-like elements formed of portions of two dihedrals, delimited by a cylindrical surface, one of the dihedrals being convex with a projecting edge and belonging to a preceding vertebra, the other dihedral being concave, namely with a reentering edge, belonging to the successive vertebra.

[ We claim:] [1.] System for support and actuation of endoluminal and/or endoscopic surgical and diagnostic instruments, the system comprising:a distal part;a proximal part; anda medial part connectively disposed between the distal and proximal parts,the distal part including a plurality of vertebral elements, each vertebral element being formed by vertebra portions having opposed ends formed in the shape of two solid dihedral angles, wherein:one of the two ends has a dihedral angle which is convex, has a protruding edge, a width 2 .beta., and is connected flexibly with a proximally adjacent one of the plurality of vertebral elements; andthe other end has a dihedral angle which is concave, a width equal to 2 (.alpha.+.beta.), and is connected flexibly to a distally adjacent one of the plurality of vertebral elements.
