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.

Tissue relaxation monitoring for optimized tissue stapling

A reusable surgical device includes a housing or body that supports one or more thermal energy storage members that retain or store heat during a cleaning and sterilization process. The stored heat functions to evaporate water that remains within the body or housing of the surgical device after the cleaning and sterilization process is completed to minimize any likelihood of infection of a patient or damage to electronics within the surgical device that may result or occur due to the presence of the water within the surgical device.

Surgical stapling device

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.

Methods and structure for confirming proper assembly of powered surgical stapling systems

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.

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.
