The present disclosure provides a circular stapler. The circular stapler includes a stapling head assembly. A trocar is positioned at least partially within the stapling head assembly. An anvil is detachably attachable to the trocar. A knob rotatable to cause translation of the trocar to adjust a position of the anvil with respect to the stapling head assembly. One or more sensors are configured to generate data associated with a trocar position or an anvil state. A communication element is configured to provide the generated data to a hub, wherein the hub is configured to provide an indicator associated with the trocar position or the anvil state based on the generated data.

A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle. The assembly can include a sled having offset ramps and/or an anvil comprising an arrangement of forming pockets proximal to the tissue stop.

A surgical instrument includes a body, a shaft assembly, an end effector, a clamp actuator, and a blade cooling system. The end effector has a clamp arm and an ultrasonic blade coupled with an ultrasonic transducer. The clamp arm is configured to selectively move from a first actuator position toward a second actuator position thereby directing movement of the clamp arm from the open position toward the closed position, respectively. The cooling system is operable to deliver fluid coolant to the ultrasonic blade to thereby cool the ultrasonic blade while the clamp actuator remains in the first actuator position.

Blade cooling gas/fluid storage

A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly configured to drive a plurality of staples against the staple forming pockets of the anvil. The stapling head assembly comprises a coupling member configured to actuate the anvil relative to the stapling head assembly, a firing assembly configured to drive the plurality of staples against the staple forming pockets of the anvil, and a deck member. The deck member includes a deck surface extending radially between an inner circular edge and an outer circular edge, and a plurality of staple openings extending through the deck surface. The plurality of staple openings define at least one cross shape.

Circular surgical stapler for forming cross-pattern of staples

A surgical stapling instrument includes an anvil and a stapling head assembly. The anvil defines staple forming pockets. The stapling head assembly includes a body, a coupling member, a firing assembly, and a staple deck. The coupling member is configured to actuate relative to the body to thereby acuate the anvil relative to the body. The firing assembly is configured to drive staples against the staple forming pockets of the anvil. The staple deck is defined by an outer arched perimeter and an inner arched perimeter fixed to the body. The staple deck defines staple openings. At least one non-tangential staple opening in the of staple openings extends along a longitudinal axis in a non-tangential relationship with a closest tangent line of the inner arched perimeter or the outer arched perimeter.
