  • Publication number: 20090206131
    Abstract: In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

  • Publication number: 20090206132
    Abstract: A surgical apparatus particularly suited for sequentially applying a plurality of fasteners to body tissue and simultaneously incising tissue is provided. A handle assembly includes a movable handle. The movable handle is movable through an actuation stroke. An elongate body extends distally from the handle assembly and defines a longitudinal axis. The elongate body has a distal end adapted to releasably engage both articulating and non-articulating disposable loading unit types. An actuation shaft is supported at least in part within the handle assembly and is mounted for longitudinal movement in response to manipulation of the actuation handle. An energy activated firing lockout system prevents operation of the surgical apparatus under a plurality of conditions.
