摘要： A surgical stapling system includes an adapter assembly (100), a trocar assembly (114) attachable to the adapter assembly, a processor (12e), and memory (12d). The memory (12d) includes instructions executable by the processor (12e) to cause the trocar assembly (114) to move relative to the adapter assembly (100) and determine whether the trocar assembly (114) is properly attached to the adapter assembly (100). 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.

摘要： A surgical stapling instrument includes an anvil assembly, a shell assembly, and an adapter assembly. The adapter assembly includes a tubular shaft supporting the shell assembly at a distal portion of the tubular shaft, and a trocar assembly transitionable between an extended configuration and a retracted configuration. The trocar assembly includes a trocar detachably supporting the anvil assembly thereon, a lead screw adapted to be coupled to an actuator for rotational input, a first member rotatably supporting the lead screw, a second member operatively coupled to the lead screw such that rotation of the lead screw causes axial displacement of the second member relative to the first member, and a light diffuser configured to scatter light received from a light source. The light diffuser is configured to be surrounded by the anvil center rod when the anvil center rod is attached to the trocar.

摘要： A surgical instrument includes an annular reload, and an anvil assembly configured to move relative to the annular reload between an open position and a preset closed position, in which the anvil assembly and the annular reload define a preset gap distance therebetween. A processor of the surgical instrument is configured to determine a difference between the preset gap distance and an actual gap distance gap distance between the anvil assembly and the annular reload, and adjust a staple stroke and a cutting stroke by the determined difference between the preset gap distance and the actual gap distance.

摘要： A circular stapling device includes a handle assembly including a processor, an adapter assembly including a trocar assembly and a strain gauge assembly, a reload assembly operably secured to the adapter assembly, the reload assembly including a staple cartridge, and an anvil assembly releasably secured to the trocar assembly and moveably positioned relative to the staple cartridge between a spaced position and a clamped position. The processor includes software for determining when tissue clamped between the staple cartridge and the anvil assembly has achieved a predetermined tissue relaxation percent. A method of optimizing tissue relaxation during a stapling procedure includes clamping tissue between an anvil assembly and a reload assembly, calculating a tissue relaxation percent of the clamped tissue, and initiating a stapling sequence when the tissue relaxation percent equals or is less than a predetermined tissue relaxation percent.

摘要： A device for loading a trocar assembly with an adapter assembly of a surgical stapling instrument and a method of confirming that the trocar assembly is properly secured to the adapter assembly are provided. The device includes a base member and an engagement arm secured to the base member. The base member defines a longitudinal passage for receiving a trocar assembly and includes a proximal end surface. The engagement arm is configured to releasably secure a trocar assembly within the base member. The engagement arm includes a proximal end surface. The proximal end surface of the base member is configured to engage a distal end surface of a trocar housing of the trocar assembly when the trocar assembly is not properly secured within the adapter assembly.

摘要： A surgical device including a handle assembly, an elongated portion, at least one window, an end effector, and a shroud is disclosed. The at least one window extends through an outer wall of the elongated portion and is configured to allow fluid to travel therethrough from an interior portion of the elongated portion to ambient air. The end effector is configured to selectively engage a distal portion of the elongated portion. The shroud is affixed to the end effector and extends proximally therefrom. The shroud is configured to cover the at least one window when the end effector is engaged with the elongated portion.

摘要： A surgical stapling instrument includes an anvil assembly, a reload assembly, an adapter assembly, a processor, and a memory. When clamping to a target force, the instructions cause the surgical stapling instrument to advance the pusher towards the anvil assembly from a first position to a second position, determine if the pusher stopped advancing towards the anvil assembly prior to the second position, measure a force of staple compression of a staple being ejected from the annular staple cartridge by the pusher, in response to the pusher having stopped advancing towards the anvil assembly, and determine if the force of staple compression is outside of a predetermined range

摘要： A cartridge assembly includes a channel member defining a cavity, and a staple cartridge including a cartridge body. A plurality of pushers disposed within the cartridge body, such that each pusher includes a staple supporting surface that defines a first concavity and a second concavity that are separated by a central radiused convexity. Each staple of a plurality of staples is received within one retaining slot of a plurality of retaining slots. Each staple of the plurality of staples includes a back span, wherein the shape of each staple of the plurality staples corresponds to the shape of the staple supporting surface of each of the plurality of pushers. An actuation sled can be moved within the cartridge body, into sequential engagement with the plurality of pushers to urge the plurality of staples through the plurality of retaining slots.
