Abstract: An apparatus includes a body assembly, a modular shaft assembly, and a coupling detection assembly. The body assembly includes a control circuit, a battery pack operable to power the control circuit, and a first electrical contact assembly. The modular shaft assembly includes a second electrical contact assembly that is configured to operatively engage the first electrical contact assembly when the modular shaft assembly selectively couples with the body assembly. A detection trigger member is configured to activate a detection activation member such that the detection activation member communicates a first detection signal to the control circuit when the modular shaft assembly selectively couples with the body assembly. The control circuit is configured to verify operative engagement between the first electrical contact and the second electrical contact in response to the control circuit receiving the first detection signal.

Abstract: A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

Abstract: An apparatus includes a body assembly, a shaft assembly, and an end effector. The shaft assembly includes an outer sheath and a motorized driving mechanism. The body assembly is configured to actuate the driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The first staple driver is configured to fire a first annular array of staples of the plurality of staples against the anvil to deform the first annular array of staples at a first compressed staple height. The second staple driver is configured to fire a second annular array of staples of the plurality of staples against the anvil to deform the second annular array of staples at a second compressed staple height independent of the first staple driver. The first compressed staple height and the second compressed staple height are different.

Abstract: An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath and a staple driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The staple deck defines a plurality of staple openings in at least one annular array. Each staple opening in the plurality of staple openings houses a staple. The anvil is configured to actuate relative to the staple deck to compress tissue between the staple deck and the anvil. The staple driving mechanism is configured to actuate the first staple driver to fire a first staple of the plurality of staples against the anvil. The staple driving mechanism is further configured to actuate the second staple driver independently of the first staple driver to fire a second staple of the plurality of staples against the anvil.

Abstract: A surgical access device includes a tissue retractor including a flexible body configured to engage tissue surrounding a tissue opening. A plurality of surgical instrument channels is arranged in a central portion of the tissue retractor. Each surgical instrument channel is configured to guide a surgical instrument distally through the surgical access device. At least one needle entrance port is arranged on a proximal portion of the surgical access device. At least one needle exit port is arranged distally of the needle entrance port. The at least one needle entrance port and the at least one needle exit port are configured to cooperate to define a needle channel extending distally through the surgical access device and obliquely relative to a central axis thereof. The needle channel is configured to guide a suture passer needle through the surgical access device and adjacent tissue to facilitate closure of the tissue opening.
