ABSTRACT:
The support consists of an architectural functional unit made up of modules articulable in such a way that the unit is to be fixed to one of the branches of the sternal separator which is placed in the patient. Structurally the support includes a section (1) for securing the sternal separator from whose section a first module made up of a tube (3) and a telescopic rod (4) immovable by a radial screw (5) emerges. This module is followed by another one made up of a tube (7) joined to the end of the rod (4), tube which is a rotation support for a fourchet (8) to whose side branches grooved sections (9) through which grounds of suture thread (23) pass are fixed. The ends of the fourchet (8) bear a rotating tube in which a rod (15) to which the prosthesis itself (17) is secured is mounted in an inclined manner and a middle piece (18) is inserted.
