  • Circular surgical stapler having staples with expandable crowns
    Patent number: 11911039
    Abstract: A surgical stapler instrument includes a stapling head assembly that receives a plurality of staples. The staples are configured with features that allow the staples to expand after deployment so that an anastomosis created by the instrument can increase in size after forming. In some versions the staples expand automatically after deployment, and in other versions the staples expand in response to tissue forces imparted upon the staples after deployment. In some versions the staples are configured to be deployed in various patterns that promote expandability of the circular staple line.

  • STAPLING INSTRUMENT COMPRISING A MOUNTED SHAFT ORIENTATION SENSOR
    Publication number: 20240023962
    Abstract: A surgical instrument comprising an articulatable end effector and an articulation control system is disclosed. The articulation control system comprises actuators that, when actuated, cause the end effector to articulate in predetermined directions. When the end effector is rotated downwardly, the articulation control system flips, or switches, the response to the inputs from the actuators.
