Abstract: A surgical instrument and method for indicating a tissue penetration site includes an inner needle and a head. The inner needle has a driver configured to translate the inner needle form a first position to a second position. The head is securely attached to the inner needle at an end opposite the driver and is configured to expand from a contracted state to an expanded state and thereby indicate the tissue penetration site.

Abstract: An end effector for use with a surgical instrument includes a lower jaw, an anvil, and a resilient member. The anvil is pivotable relative to the lower jaw between a fully opened position and a fully closed position. The resilient member is configured to bias the anvil to remain in the fully opened position when the anvil is in the fully opened position. The end effector may include a closure ring coupled with the anvil that is translatable relative to the lower jaw and configured to engage the anvil at an interface as the closure ring translates proximally relative to the lower jaw to thereby pivot the anvil relative to the lower jaw toward the fully opened position. In various embodiments, the resilient member may comprise elastomeric material positioned between the closure ring and the anvil or a pair of springs or resilient arms that engage the anvil.

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.
