  • Dual stage closure system for circular surgical stapler
    Patent number: 11207071
    Abstract: An apparatus includes a handle assembly having a body, a shaft assembly having an outer tube member, an end effector, an anvil, a first trocar closure system, and a second trocar closure system. The end effector has having a staple deck fixed relative to the body, a staple driver operable to actuate relative to the staple deck between an unfired position and a fired position, and the trocar configured to selectively couple with the anvil and actuate relative to the staple dreck. The first trocar closure assembly can actuate in a first motion to drive the trocar between a distal position and a first closed position. The second trocar closure assembly can actuate in a second motion between the first closed position and a second closed position. The staple drive is inoperable at least until the first trocar closure assembly actuates the trocar to the first closed position.
