| 摘要 |
<p>The invention concerns an intramedullary nail to be inserted into a fractured long bone, for example a femur, comprising:
a rod (2) extending between a proximal end (3) and a distal end (4), in which the rod (2) is of the cannulated type, and having an inner surface;
at least one portion of the rod (2) being substantially rectilinear and having longitudinal axis (X);
a tubular sleeve (5) in which the rod (2) is inserted coaxially, and having an outer surface;
a side wall defined between the inner surface of the rod (2) and the outer surface of the tubular sleeve (5). This wall is intersected by a channel (6) formed at the proximal end (3) of the rod (2); the channel (6) extends along an axis (Y) forming an acute angle (²) with the longitudinal axis (X) of the rod (2) and is shaped to receive a stop screw (S) of the nail (S) so that it holds the nail (1) itself stable within the bone. Advantageously, the channel (6) has an inlet opening (7) at the proximal mouth of the rod (2) and an outlet opening (8) at the outer surface of the tubular sleeve (5).</p> |
