  • Publication number: 20240000449
    Abstract: A tissue thickness compensator can comprise a compensator body and at least one vessel contained in the compensator body. The vessel can define an inner cavity which can comprise an inner atmosphere having a pressure which is lower than the atmospheric pressure of the atmosphere surrounding the tissue thickness compensator. In at least one embodiment, the vessel and the compensator body can be maintained in a collapsed state until staples are fired through the vessel. At such point, the vessel can re-expand and apply a biasing force to tissue captured within the staples.

  • Patent number: 11850013
    Abstract: Robotic surgical systems are provided. In one exemplary embodiment, a robotic surgical system includes an electromechanical arm, a motor housing, a tool shaft, an end effector, and an articulation actuation system. The tool shaft includes a central body and a joint assembly having master and slave joints. The end effector is configured to move in response to movement of the slave joint. The articulation actuation system is configured to act directly on the master joint without directly acting on the slave joint to move the master joint in at least one plane. The master and slave joints are operably coupled to each other such that movement of the master joint causes parallel movement of the slave joint while maintaining a position of a longitudinal axis of the central body of the tool shaft to thereby effect articulation of the end effector. Surgical systems and methods are also provided.

  • Patent number: 11812960
    Abstract: 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.
