The invention concerns a perfected device for the transosseous insertion of suture threads. This device comprises a main body (1) supporting a protruding cannula (3) provided with an active end (30); the device comprises a flexible threadlike element (4), on which there are fashioned a sharp tip (40) and an opening (41) that serves for the threading of at least one suture thread (5), said element (4) being housed in a coaxially sliding manner inside said cannula (3) and, on command, exiting from the active end (30) of the cannula, assuming a curved position; the device comprises first means for producing the coaxial movement of the threadlike element (4) in the two directions with respect to the cannula (3) and second means for producing a coaxial movement of the threadlike element in the exiting direction from the cannula (3); for a short tract, the movement produced by the second means is disengaged from the advancement of the threadlike element produced by the first means. |
