Endomedullar device for nailing long distance

Claim 1

An endomedullar device for nailing long bones; the device comprising an elongated tubular body for insertion inside the bone and presenting an axis; and connecting means for connecting said elongated tubular body to the bone; said connecting means comprising at least first connecting means associated with one end of the tubular body; wherein said first connecting means comprising at least one pair of first deformable nails; first guide means for guiding each of said first nails along a respective path; and first operating means for moving and deforming said first nails between a withdrawn idle position wherein the first nails extend at least partly inside said tubular body and a forward operating position wherein said first nails project outside of said tubular body and are inserted at least partly inside the bone; said first guide means defining, for each first nail, a respective first guide conduit extending along the respective said path and wherein each said first guide conduit comprises a first portion extending crosswise to said axis and presenting a length, the projection of which on to a plane perpendicular to said axis is greater than half the transverse dimension of the elongated tubular body measured in said plane.

Claim 4

A device of any one of claims 1 or 2, wherein each said a first guide conduit includes a substantially straight portion.

Claim 12

A device as claimed in any one of claims 1 or 2 wherein said first conduits present respective outlets; and said first nails project from respective said outlets in directions substantially perpendicular to said axis.

Claim 14

A device of any one of claims 1 or 2 characterized in that said first nails present a substantially circular cross section and an outwardly tapering free end portion.

Claim 15

A device of any one of claims 1 or 2 characterized in that said first guide means comprise an end body connected integral with one end of said elongated tubular body; said first conduits being formed in said end body.

Claim 17

A device of any one of the foregoing claims 1 or 2 wherein first operating means comprise a slide slidable inside said tubular body.

Claim 18

A device of any one of claims 1 or 2 wherein said connecting means also comprise second connecting means separate from and substantially similar to said first connecting means.
