What is claimed is: A suture staple applicator system, comprising: (a) a suture staple applicator (100) for firing a suture staple (150) onto a suture (131), the staple applicator comprising : a cover (110)； an elongated plunger (120) supported with the ability to slide on the cover, the plunger having a distal end part (122) disposed within the cover and a proximal end part (123) extending from a proximal end of the cover ； a hollow tube (160) extending distally from the cover and defining a lumen therethrough； a drive element (130) having a distal end that extends into the hollow tube (160) and a proximal end operatively coupled with the plunger (120)； and a work tip (140) coupled to a distal end of the hollow tube (160), where the work tip has a cross-sectional profile, essentially U-shaped defining a channel (146) having a wall base (146a) and a pair of separate side walls (146b, 146c), where the working tip defines: a lower contact surface along an inner face of the base wall (146a) and a surface of defined upper contact along an upper end surface of each side wall (146b, 146c), wherein the upper contact surface of each side wall includes: a distal ejection shoulder (141e) and a distal recess (141d) formed near a distal end thereof and a proximal recess (141b) formed proximal to the distal recess； and an internal retention surface (146d, 146e) on both side walls parallel to the base wall, where the distal end of the actuator (130) is configured to engage a suture clip (150) loaded on the tip of work (140)； and (b) a suture clip (150) that can be loaded and deployed from the working tip (140) of the suture clip applier, the suture clip comprising: an elongated flexible rod (151) having a portion of distal end, a proximal end portion, an upper surface and a lower surface, the flexible bar also including a pair of arms (155) extending laterally therefrom； and an elongated rigid channel (152), wherein the elongated rigid channel has a cross-sectional profile, essen
