An appliance for storing, distributing and placing surgical fasteners comprises a handgrip body and an elongate element attached to the handgrip. The elongate element includes a magazine slide adapted to be displaced in the elongate element by a control rod. The control rod can be, in turn, actuated by the handgrip. The magazine slide also has surgical fasteners. Each surgical fastener has an anchoring bar, a catching bar and a connecting strip. A distal part of the anchoring bar has a conical shape. A distal end of the distal part of the anchoring bar has a hemispherical shape.
The invention claimed is: 1. An assembly comprising at least one couched I-shaped surgical fastener (A) and an appliance (1) for storing, distributing and placing such fasteners, comprising: a handgrip body (B) equipped with at least one control means (8, 10) and an elongate element (C) attached an
The invention claimed is: 1. An assembly comprising at least one couched I-shaped surgical fastener (A) and an appliance (1) for storing, distributing and placing such fasteners, comprising: a handgrip body (B) equipped with at least one control means (8, 10) and an elongate element (C) attached and fixed to the handgrip (4), in which appliance the elongate element (C) is made up of a body (20) of tubular overall shape containing: a magazine slide (22) movable through the elongate element (C) and being configured and dimensioned to retain the at least one surgical fastener (A), each surgical fastener (A) including an anchoring bar (2), a catching bar (3) and a connecting strip (4), said magazine slide (22) being movable through the elongate element (C) by a control rod (24) which can be actuated by the control means (8, 10) of the handgrip (6), the magazine slide (22) being secured to a slotted and longitudinal hollow ejection barrel (50) projecting from the distal end of said magazine slide (22) and able to project from the elongate element (C), and, the tubular body (20) including means (23, 41) for distributing the stored fasteners (A) one by one via transfer of the anchoring bar (2) into a receiving seat (55) formed in the magazine slide (22), wherein an ejection plunger (42) is operatively connected to the control means (8, 10) of the handgrip (6) and positioned in alignment with the ejection barrel (50) so as to push the anchoring bar (2) of the fastener into the ejection barrel, characterized in that: the anchoring bar includes a cylindrical portion and a conical portion extending distally from a distal end of the cylindrical portion, the conical portion including a distal tip having a hemispherical shape, the surface of the distal end of the ejection barrel (50) is arranged in a plane substantially perpendicular to the longitudinal axis of the tubular body (20). 2. An assembly including an appliance (1) and a plurality of I-shaped surgical fasteners (A), comprising: a handgrip body equipped with at least one control means (8, 10), and an elongate element (C) attached and fixed to the handgrip (4), 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 (A), each fastener (A) having an anchoring bar (2), a catching bar (3) and a connecting strip (4), said magazine slide (22) being displaceable in the elongate element (C) by a control rod (24) which can be actuated by the control means (8, 10) of the handgrip (6), the magazine slide (22) being secured to a slotted and longitudinal hollow ejection barrel (50) projecting from the distal end of said magazine slide (22) and able to project from the elongate element (C), and means (23, 41) positioned within the tubular body (20) for distributing the stored fasteners (A) one by one, this distribution involving the transfer of the anchoring bar (2) of the first fastener into a receiving seat (55) formed in the magazine slide (22) and, an ejection plunger (42) which can be displaced by the control means (8, 10) of the handgrip (6) and which is arranged in alignment with the ejection barrel (50) so as to push the anchoring bar (2) of the first fastener in the ejection barrel, characterized in that: the anchoring bar includes a cylindrical portion and a conical portion extending distally from a distal end of the cylindrical portion, the conical portion including a distal tip having a hemispherical shape; and the surface of the distal end of the ejection barrel (50) is arranged in a plane substantially perpendicular to the longitudinal axis of the tubular body (20). 3. Appliance (1) according to claim 2, characterized in that the ejection barrel (50) is made of plastic and is moulded in one piece with the magazine slide (22). 4. Appliance according to claim 2, characterized in that the fastener (A) is made of biocompatible plastic. 5. Appliance according to claim 4, characterized in that the fastener (A) is made of bioabsorbable plastic. 6. Appliance (1) according to claim 5, characterized in that the bioabsorbable plastic is a lactic acid polymer. 7. Appliance (1) according to claim 2, characterized in that the length of the projecting part of the ejection barrel (50) at the moment of ejection is less than or equal to 3 mm. 8. Appliance (1) according to claim 2, characterized in that the total length L′ of the fastener (A) in its operating position is less than or equal to 10.5 mm. 9. Appliance (1) according to claim 2, characterized in that the total height H of the fastener (A) in its operating position is less than or equal to 6.1 mm. 10. Appliance (1) according to claim 2, characterized in that the elongate element C comprises a step-by-step system (23) able to move the stored fasteners A by a step P having a value equal to the length L of the catching bar (3) of a fastener A, this step-by-step system (23) comprising a rack (28) effecting a drawer movement upon each ejection and being equipped with a shuttle (32) which is mounted so as to slide on this rack (28), this shuttle (32) cooperating with fixed notches (35) of the magazine slide (22) in order to advance by a step P on the rack (28) upon each ejection. 11. The appliance according to claim 2, further comprising a projecting tooth extending radially from the conical portion of the anchoring bar. 12. The appliance according to claim 2, further including a non-return mechanism adapted for allowing repeated repositioning of the handgrip between a first position and a second position without repositioning the control rod, the non-return mechanism including a control lever operably coupled to a wheel, wherein a tooth of the control level engages a branch of the wheel as the handgrip is repositioned from the second position toward a third position, thereby inhibiting the handgrip from returning to the first position until completion of an actuation stroke.
