Abstract
An endomedullar device for nailing long bones is disclosed. The device includes an elongated tubular body for insertion inside the bone. A connecting mechanism for connecting the body to the bone is made up of at least a pair of deformable nails and an operating mechanism for moving the deformable nails between a withdrawn idle position inside the tubular body and an operating position where the nails project outward of the tubular body and into the bone.
Claims17
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- and first operating means for moving and deforming said first nails between a withdrawn idle position wherein the first nails extend at least partly inside said tubular body and a forward operating position wherein said first nails project outside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.
