Abstract
Abstract The surgical suturing apparatus is configured to pass a surgical suturing needle having an associated length of suture material attached thereto between opposed pairs of jaws. The surgical suturing apparatus generally includes a housing having an elongated tubular portion extending distally therefrom. A pair of jaws extend distally from the elongated tubular portion and are each individually longitudinally movable with respect to the elongated tubular portion and with respect to each other. Each of the jaw structures includes a jaw and a securing mechanism for tightly holding the surgical needle within the jaw. Parts of the securing mechanism engaging the needle also move longitudinally with respect to the associated jaw and the elongated tubular portion. Various control structures are provided to advance the securing mechanism relative to its associated jaw to secure the surgical needle therein and to move the entire jaw structure longitudinally with respect to the suturing apparatus.
