Claims

1.- 17. (canceled)
18. A device for reconstructing a spinous process, comprising:
a main portion having at least a first engaging hole;
one fixing bar transversely insertable into the engaging hole; and
said main portion having at least one through-seat for inserting ligaments to be reconstructed.
19. The device according to claim 18, wherein the tapered portion comprises a substantially tapered shape comprising a widened portion and a narrow portion; the engaging hole being disposed in the widened portion.
20. The device according to claim 19, wherein the engaging hole comprises a polygonal geometry compatible and coupleable with a coupling portion of said fixing bar.
21. The device according to claim 18, wherein said main portion comprises a plurality of lightening holes.
22. The device according to claim 21, wherein the device comprises a fastening pin able to block said main portion in a position along the axis of said transverse fixing bar.
23. Spinal fixing equipment, comprising:
a main portion having at least a first engaging hole, wherein the main portion has at least one through-seat for inserting ligaments to be reconstructed;
one fixing bar transversely insertable into the engaging hole;
a pair of side longitudinal bars suitable for being arranged in a sagittal direction along the sides of the spinous processes of the cervical and/or spinal vertebrae; and
a connection element between each of said longitudinal bars and said transverse fixing bar.
24. The fixing equipment according claim 23, wherein the connection element comprises:
a main body comprising at least a first housing seat for one of the two longitudinal bars, and a second housing seat for the transverse fixing bar;
tightening means which locks the pair of longitudinal bars and the fixing bar in an operative position with respect to the main body and preventing relative movements between said bars; and
interference means which restrains the sliding at least of the transverse fixing bar within the respective seat.
25. The fixing equipment according to claim 23, wherein the first and second housing seats are arranged on parallel planes and extend along directions transverse to each other.
26. The fixing equipment according to claim 25, wherein the first seat is defined by a partially open groove formed in the main body.
27. The fixing equipment according to claim 25, wherein the second seat comprises a through hole inside the main body.
28. The fixing equipment according to claim 24, wherein said first seat is in communication with said second seat.
29. The fixing equipment according to claim 24, wherein the interference means projects within the first or second seat.
30. The fixing equipment according to claim 29, wherein the interference means comprises an elastic member suitable for applying a pressure force against the transverse fixing bar.
31. The fixing equipment according to claim 30, wherein the elastic member is a spring wire protruding within the second housing seat.
32. The fixing equipment according to claim 24, wherein the tightening means includes an fastening screw.
33. The fixing equipment according to claim 24, wherein the interference means and the tightening means act inside a respective housing each extending along a direction orthogonal to the axial extension direction of the first and second seats.
34. The fixing equipment according to claim 33, wherein the housing for the interference means and the housing for the tightening means are in communication with the second seat.
