Patent ID: 7569063

Claim:
A device for deploying and ejecting a recumbent I-shaped surgical fastener, the fastener having an anchoring bar, a stop bar and a linking strip, the device intended to be positioned adjacent a distal end of an instrument for storing, dispensing and positioning fasteners, the device having a longitudinal axis, a proximal end and a distal end that lies in a first plane approximately orthogonal to the longitudinal axis and includes a first longitudinal channel emerging at the proximal and distal ends of the device, in which the anchoring bar of the fastener can slide longitudinally up to a point where it is ejected at the distal end of the device, the first longitudinal channel having a longitudinal slot intended for passage of the linking strip of the fastener during the sliding, wherein the device has an approximately longitudinal bearing face that defines an open half-space not containing the first longitudinal channel and in that the device further includes: a second longitudinal channel in which the stop bar can slide towards the distal end of the device, the second longitudinal channel lying approximately in the first plane, emerging at the proximal end of the device and extending into the open half-space against the bearing face; a first cam that closes off the distal end of the second longitudinal channel, designed to form a stop surface for a distal part of the stop bar and to allow sliding from the distal end of the device in the opposite direction to the first channel, so as to produce a pivoting movement of the stop bar; at least one approximately transverse splaying cam, located proximal to the first cam, capable of cooperating with the at least one of the linking strip and the stop bar in order to cause a lateral splaying movement of the proximal part of the stop bar away from the bearing face; and an approximately transverse escapement cam, located between the first cam and the at least one approximately tranverse splaying cam, capable of cooperating with the distal part of the stop bar in order to allow lateral displacement of the distal part of the stop bar away from the bearing face, and its disengagement from the first cam.
