Abstract: A surgical stapling system includes an adapter assembly, a trocar assembly attachable to the adapter assembly, a processor, and memory. The memory includes instructions executable by the processor to cause the trocar assembly to move relative to the adapter assembly and determine whether the trocar assembly is properly attached to the adapter assembly. Such determination is based on an amount of force applied between the trocar assembly and the adapter assembly, an amount of current detected in the surgical stapling system, or an amount of time the trocar assembly moves relative to the adapter assembly without an indication that the amount of force is within a predetermined range.

Abstract: A surgical stapling device includes a visualization device that extends through a body of the stapling device to facilitate visualization of tissue that surrounds an end effector of the stapling device. An anvil assembly of the surgical stapling device is adapted to facilitate passage of the visualization device through the anvil assembly.

Abstract: A handheld electromechanical surgical device, capable of effectuating a surgical procedure, includes a handle assembly having a power source; at least one motor coupled to the power source; and a controller configured to control the motor. The surgical device includes an adapter assembly having an electrical assembly having a proximal end in communication with the controller of the handle assembly. The surgical device includes a reload configured to selectively connect to a distal end of the adapter assembly. The reload includes an annular array of staples; an annular staple pusher for ejecting the staples; and a data storage device selectively connectable to a distal end of the electrical assembly. The data storage device receives and stores performance data of the surgical device from the controller of the handle assembly.

Abstract: An adapter for a circular stapling instrument includes an elongate body supporting a loading unit and from which a trocar member extends. The trocar member includes a first magnetic member and an anvil assembly of the circular stapling instrument includes a second magnetic member.

Abstract: A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes housing, a trocar member slidably supported within the housing between a retracted position and an advanced position, and a chive member rotatably supported within the housing and in operable engagement with the trocar member to cause longitudinal movement of the trocar member relative to the housing between an advanced position and a retracted position. The housing includes a tubular body having a distal portion and an end cap assembly secured to the distal portion. The trocar member includes a proximal portion and at least one tab disposed on the proximal portion. The at least one tab is configured to engage the end cap assembly when the trocar member is in the advanced position to prevent further advancement of the trocar member.
