An apparatus for suturing anatomical tissue (40) includes a hollow needle guide (62) having a distal end (60), a needle (82) disposed within the needle guide. The needle is movable between a retracted position where at least a portion of the needle is disposed within the needle guide and an extended position where the needle is disposed externally of the needle guide. Suture material (86) is connected to the needle. A manually articulable needle receiver (46) for guides the distal end of the needle as a proximal end is advanced through the needle guide and captures the needle when the proximal end of the needle emerges from the distal end of the needle guide.

L'invention porte sur un appareil permettant de suturer un tissu anatomique (40), comprenant un guide (62) d'aiguille creuse ayant une extrémité distale (60), une aiguille (82) située dans le guide. L'aiguille peut se déplacer entre une position de retrait où elle se trouve, au moins en partie, dans celui-ci et une position de détente où elle se trouve à l'extérieur du guide. Le matériel de suturation (86) est relié à l'aiguille. Un récepteur (46) d'aiguille pouvant être articulé à la main sert à guider une extrémité distale de l'aiguille quand son extrémité proximale s'avance à travers le guide et à se saisir de l'aiguille lorsque son extrémité proximale sort de l'extrémité distale du guide d'aiguille.
