A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

A surgical instrument including a first portion and a second portion, wherein the second portion can be sterilized separately from the first portion.

The second portion can comprise electronic components configured to control the surgical instrument and / or record data collected during the use of the surgical instrument. The first portion can be sterilized using a gamma radiation sterilization process while the second portion can be sterilized using a different sterilization process, such as steam, ethylene oxide, ozone, and / or hydrogen peroxide sterilization processes, for example. As a result, the first and second portions can be sterilized separately and delivered in two separate containers. The second portion can be stored within a sealed bag and can include an electrical terminal which can penetrate the bag and communicate with the first portion.

The procedure further comprises removing an internal organ or other tissue from the operating area in order to make room and add visibility for the laparoscopic intervention, detaching the spatulate element from the positioner, and withdrawing the positioner through the trocar port and the spatulate through the hand port.

Surgical systems and related methods verify the presence of an unfired surgical cartridge mounted to a surgical instrument. The cartridge includes an input that is actuated in a firing direction to operate the cartridge. An actuation input that is limited to less than or equal to a predetermined magnitude is generated. The actuation input includes at least one of a torque or a force. The actuation input is transferred to an output of a surgical instrument to attempt to actuate the output opposite to the firing direction by a predetermined amount. The output is drivingly coupled with the cartridge input when the cartridge is mounted to the surgical instrument. The resulting actuation of the output is measured and compared with a threshold actuation amount. A determination is made that the cartridge is present and unfired when the resulting actuation of the output is less than the threshold actuation amount.
