An apparatus and a method for surgical suturing with thread management (72). An apparatus for tissue suturing comprising a cartridge (24) having a suturing needle (26) having a pointed end and a blunt end, the suturing needle (26) capable of rotating about an axis; a pusher assembly (9) comprising a cartridge holder (20) having a needle rotation drive capable of releasably engaging the cartridge (24) and rotating the suturing needle (26) about the axis; and an actuator (12) capable of releasably engaging the needle rotation drive to rotate the needle rotation drive. A method for suturing tissue comprising placing a suturing device (1) having a cartridge (24) containing a suturing needle (26) to span separated tissue segments; activating an actuator (12) to cause rotational movement of the suturing needle (26) through the separated tissue segments; and deactivating the actuator (12) to stop an advancing movement of the suturing needle (26) to cause a suturing material (100) to be pulled through the separated tissue segments forming a stitch.

L'invention concerne un appareil et un procédé de suture chirurgicale avec gestion de fil. Cet appareil, destiné à suturer des tissus, comprend une cartouche équipée d'une aiguille de suture dont une extrémité est pointue et une autre est émoussée, cette aiguille pouvant entrer en rotation autour d'un axe, un assemblage pousseur comprenant un support de cartouche doté d'un entraînement permettant d'engager la cartouche de façon amovible et de faire entrer l'aiguille en rotation autour de l'axe, et un actionneur pouvant s'engager, de façon amovible, à l'entraînement qui permet d'assurer la rotation de cet entraînement. L'invention concerne aussi un procédé de suture de tissu consistant à placer un dispositif de suture, comportant une cartouche contenant une aiguille de suture, afin de mettre à portée des segments séparés de tissu, à activer un actionneur mettant en rotation l'aiguille de suture à travers les segments séparés de tissu, et à désactiver l'actionneur afin d'arrêter un mouvement d'avancement de l'aiguille afin que le matériau de suture soit tiré à travers les segments séparés de tissu, formant ainsi une suture.
