Abstract
A suturing instrument includes a handle, an elongate shaft, and a suturing head. One or more pull wires extend from the handle into the elongate shaft for controllably deflecting a deflectable portion of the elongate shaft in one or more directions and/or planes for improved maneuverability within the body of a patient during an endoscopic or laparoscopic surgical procedure and for changing the positioning of the suturing head.
Claims18
A suturing instrument, comprising
- a handle having a housing defining a cavity;
- an elongate shaft extending from the handle, at least a portion of the elongate shaft being flexible;
- one or more pull wires extending from the handle into the flexible portion of the elongate shaft for deflecting the flexible portion of the elongate shaft;
- a steering button extending from the housing and operatively coupled to a cam, the cam being disposed within a pocket of a frame member, the frame member being disposed within the cavity of the housing;
- and
- a suturing head extending from a distal end of the elongate shaft, the suturing head comprising a needle carrier channel, a needle carrier configured to releasably hold a needle, and a needle catch, the needle carrier being movably disposed within the needle carrier channel.
