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