The present invention relates to an appliance for storing, distributing and placing couched I-shaped surgical fasteners, comprising a handgrip body equipped with at least one control means, and an elongate element (C) attached and fixed to the handgrip, in which appliance the elongate element (C) is made up of a body (20) of tubular overall shape containing: near its distal end, a magazine slide ( 22 ) itself containing couched I-shaped fasteners having an anchoring bar, a catching bar and a connecting strip, said magazine slide ( 22 ) being displaceable in the elongate element (C) by a control rod ( 24 ) which can be actuated by the control means of the handgrip and, on the other hand, secured to a slotted and longitudinal hollow ejection barrel projecting from the distal end of said magazine slide ( 22 ) and able to project from the elongate element (C), and, in its tubular body ( 20 ), on the one hand, means ( 23 ) for distributing the stored fasteners one by one, this distribution involving the transfer of the anchoring bar of the first fastener into a receiving seat arranged in the continuation of the ejection barrel ( 50 ) and, on the other hand, an ejection plunger which can be displaced by the control means of the handgrip and which is arranged in alignment with the ejection barrel so as to push the anchoring bar of the first fastener into the latter, characterized in that: the distal part of the anchoring bar of the fasteners is of conical shape, and the distal end of this distal part is of hemispherical shape, the surface of the distal end of the ejection barrel is arranged in a plane substantially perpendicular to the longitudinal axis of the tubular body. The present invention relates also to a surgical fastener.
