  • Publication number: 20220395288
    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.

  • Publication number: 20220378425
    Abstract: A surgical stapling instrument comprising an articulatable end effector including a staple cartridge is disclosed. The stapling instrument further comprises an articulation drive configured to articulate the end effector and a staple firing drive configured to fire the staples from the staple cartridge during a staple firing stroke. The articulation drive is selectively engageable with the staple firing drive to articulate the end effector and decoupled from the staple firing drive during the staple firing stroke. The stapling instrument further comprises a control system that is configured to compensate for the net displacement of the staple firing drive that occurs when articulating the end effector.

  • Patent number: 10987123
    Abstract: Various example embodiments described herein are directed to articulating surgical instruments for treating tissue comprising an end effector and a shaft extending proximally from the end effector along a longitudinal axis. In certain embodiments, the shaft comprises a plurality of transverse spacer members as well as first and second rotatable members extending through at least a portion of the plurality of transverse spacer members. The first and second rotatable members may both be biased away from the longitudinal axis such that their respective directions of bias vary with rotation of the first rotatable member. When the respective directions of bias of the first and second rotatable members oppose one another, the shaft may be substantially straight. When the respective directions of bias of the first and second rotatable members are aligned with one another, the shaft may articulate away from the longitudinal axis in the direction of the alignment.
