摘要： 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.

摘要： 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.

摘要： A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a spent cartridge indication system for providing an indication of whether the loading unit has been previously fired. Other embodiments are disclosed that employ a blade monitoring system for providing feedback to the user concerning the amount of strain being experienced by the blade during cutting and stapling.

摘要： A surgical cutting and fastening instrument. The instrument comprises an end effector, a shaft connected to the end effector, and a handle connected to the shaft. The handle comprises an electric, DC motor connected to a drive train for powering the drive train and a plurality of series-connected DC power source connected to the motor for supplying electrical power to the motor. The handle also comprises a power source selection switch for connecting, when in a first state, all of the DC power sources to the motor, and, when in a second state, a subset of the DC power sources to the motor. Also disclosed are means for actuating a RF electrode in the end effector and means for indicating actuation of the RF electrode.
