A method of operating a surgical instrument includes clamping tissue with a surgical instrument end effector and actuating the end effector to drive staples into the clamped tissue, including a first longitudinal row having at least one first formed staple with a first formed shape in which the first legs are aligned laterally with each other and with the first crown; a second longitudinal row having at least one second formed staple with a second formed shape in which each second leg is skewed laterally away from the second crown at a first angle; and a third longitudinal row of third formed staples having at least one third formed staple with a third formed shape in which each third leg is skewed laterally away from the third crown at a second angle.

Method of surgical stapling

The disclosed technology includes a surgical instrument that may include a hollow housing, a trigger, and a particulate skirt. The hollow housing may include a first shell and a second shell that form an actuating mechanism space therebetween. The hollow housing may also include a handle portion and a first opening that can be formed at a first interface point of the first shell and the second shell. The trigger may extend from the first opening of the hollow housing. The particulate skirt may be configured to capture particulate from the actuating mechanism space and prevent the particulate from exiting the housing through the first opening. The particulate skirt may include a trigger aperture that can be sized and shaped to accept at least a portion of the trigger therethrough.

Particulate collector covers

A stapling assembly for a surgical instrument includes a body extending along a longitudinal axis and having an upper deck, a plurality of pockets extending through the upper deck for receiving respective staples and arranged in at least two longitudinal rows, a plurality of staple drivers, and a staple driver actuator. The stapling assembly also includes a plurality of pocket extenders extending upwardly from the upper deck. Each pocket extender has a respective top surface. The stapling assembly further includes at least one upwardly-facing surface configured to contact an adhesive of an adjunct for securing the adjunct to the stapling assembly. The at least one upwardly-facing surface is disposed at least partially between at least a portion of the upper deck and the top surfaces of the plurality of pocket extenders, and spans laterally at least partially across at least two longitudinal rows of the plurality of pockets.

A surgical instrument includes a handle assembly, a shaft assembly, an end effector and a clamp force sensor. The handle assembly includes a closure trigger that is pivotable between a released position and an actuated position. The end effector is coupled with the shaft assembly and includes a cartridge that includes an anvil and a cartridge housing. The cartridge housing is slidable with respect to the anvil between an unclamped position and a clamped position to facilitate selective clamping of patient tissue therebetween. The clamp force sensor is associated with the end effector and is configured to detect a clamping force between the anvil and the cartridge housing and facilitate generation of a notification as a function of the detected clamping force.

Surgical stapler with clamp force sensor

A surgical instrument includes a body assembly, a shaft assembly, a stapling head assembly disposed at a distal end of the shaft assembly, and an anvil. The stapling head assembly having a deck member and a closure shaft capable of moving relative to the deck member. The anvil including a head, a shank, a biasing body, and a electronic unit having a distance sensor. The head and the shank being capable of moving relative to each other. The biasing body being interposed between the head and the shank with a known spring constant. The distance sensor being capable of measuring a relative distance between the shank and the head, while the electronic unit can communicate a parameter associated with the relative distance to a console.

Intelligent anvil for circular surgical stapler

A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component.

Method of using a powered stapling device

A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component. The surgical stapling assembly can be configured to form different staple shapes, such as non-planar staples and planar staples, can include an eccentrically-driven firing assembly, and/or can include a floatable component. The surgical stapling assembly can include a staple cartridge including a longitudinal support beam.

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.

Method of suturing a trocar path incision

An obturator configured for use with a trocar includes a head and a distally extending shaft configured to be received within a working channel of a trocar. The obturator further includes a distal tip configured to puncture tissue, first and second needle entrance ports each arranged on at least one of the head or the shaft, and first and second needle exit ports arranged on the shaft. The first and second needle entrance ports communicate with the first and second needle exit ports, respectively, to define respective first and second suture paths extending obliquely to the central axis. Each of the first and second suture paths includes at least one sealing element. In some examples, the obturator further includes at least one deployable member coupled to the shaft and configured to project radially outwardly in a deployed position.
