    Abstract: Surgical instruments and control systems therefor are disclosed. A surgical instrument (1010) can comprise: a power circuit comprising a power source and a switch, a microcontroller coupled to the power circuit, a handle (1042) comprising an attachment portion, and a control circuit in signal communication with the microcontroller. The attachment portion can comprise a first electrical contact in signal communication with the microcontroller. The control circuit can comprise a sensor configured to detect an attachment state of the attachment portion. The control circuit can communicate the detected attachment state to the microcontroller, and the microcontroller can ignore signals from the first electrical contact when the control circuit communicates a detached state. The attachment portion can comprise a second electrical contact coupled to a second power circuit, and the second power circuit can decouple the second electrical contact and the second power source when the sensor detects the detached state.

    Abstract: A surgical stapling device for sequentially applying a plurality of fasteners to body tissue and simultaneously incising tissue is provided. The surgical stapling device is adapted to receive disposable loading units having staples in linear rows whose length can be between about 30 mm and 60 mm. The disposable loading unit includes a proximal body portion, a mounting assembly and a tool assembly. The mounting assembly is secured to the proximal end of the tool assembly and pivotally mounted about a pivot axis to the distal end of the proximal body portion. A support member or blow-out plate assembly is positioned on opposite sides of the pivot avis and extends between the proximal body portion and the mounting assembly. An axial drive assembly is slidably positioned between the support members and is translatable through the cartridge assembly to eject staples from the cartridge assembly. The support members prevent outward buckling of the axial drive assembly during actuation of the device especially when the tool assembly is articulated. Preferably, a protrusion is provided in the proximal body portion of the disposable loading unit at a position to frictionally engage an articulation link. Engagement between the protrusion and the articulation link retains the articulation link at a fixed position within the proximal body portion to maintain the tool assembly in a desired orientation until a predetermined axial force is applied to the articulation link. The disposable loading unit also preferably includes a locking member which is operably connected to the axial drive assembly. The locking member provides an audible and/or tactile indication that the device has been actuated.

    Abstract: A surgical stapling apparatus (10) comprising a housing, handle (24), elongated body (14), advancement assembly, and retraction mechanism (58) is provided. The movable handle is supported by the hosing, the movable handle being movable through an actuation stroke. The elongated body extends distally from the housing and defines a longitudinal axis, the elongated body having a distal end adapted to releasably engage a disposable loading unit. The advancement assembly includes an actuation shaft (46) and a driving pawl (42), the actuation shaft having a toothed rack (48) and being supported at least in part within the housing, the driving pawl being operatively associated with the movable handle and biased into engagement with the rack, wherein during the actuation stroke, the driving pawl is movable to effect longitudinal advancement of the actuation shaft. The retraction mechanism includes a release plate (64) operatively associated with the actuation shaft, the release plate being movable relative to the actuation shaft into operative engagement with the driving pawl to disengage the driving pawl from the rack.
