1. System for support and actuation of endoluminal and/or endoscopic surgical and diagnostic instruments, the system comprising:
- a distal part;
a proximal part; and
a 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 β
, and is connected flexibly with a proximally adjacent one of the plurality of vertebral elements; and
the other end has a dihedral angle which is concave, a width equal to 2 (α
+β
), and is connected flexibly to a distally adjacent one of the plurality of vertebral elements.
