Embodiment Construction

[0019] Devices and methods for optimizing tissue stapling are now described in detail with reference to the drawings, wherein like reference numerals represent like or corresponding elements in each of the several views. As used herein, the term "distal" refers to the portion of the component that is further from the user, while the term "proximal" refers to the portion of the component that is closer to the user. Additionally, the term "clinician" is often used to refer to medical personnel, including doctors, nurses, and support staff. As used herein, the term "about" means that the value is approximate and minor variations would not significantly affect the practice of the disclosed aspects of the disclosure. Where numerical limitations are used, unless the context dictates otherwise, "about" means that the numerical value may vary ±10% of the stated value and remain within the scope of the disclosure.

Abstract

The invention relates to tissue relaxation monitoring for optimized tissue stitching. A circular suturing device is disclosed, and the circular suturing device comprises a handle assembly, wherein the handle assembly comprises a processor; an adapter assembly which comprises a trocar assembly and a strain gauge assembly; a reloading assembly which is operably fixed to the adapter assembly, wherein the reloading assembly comprisesa staple cartridge; and an anvil assembly releasably secured to the trocar assembly and movably positioned relative to the cartridge between a spaced position and a clamped position. The processor includes software for determining when tissue clamped between the cartridge and the anvil assembly has reached a predetermined percentage of tissue relaxation. The invention also discloses a method of optimizing tissue relaxation during a stapling procedure, and the method includes comprises the steps of clamping tissue between an anvil assembly and a reloading assembly, calculating a tissue relaxation percentage of the clamped tissue, and initiating a stapling sequence when the tissue relaxation percentage is equal to or less than a predetermined tissue relaxation percentage.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of the filing date of U.S. Provisional Application No. 63 / 028,136, filed May 21, 2020. technical field [0003] The present disclosure relates generally to powered surgical stapling devices, and more particularly to powered surgical stapling devices including software that utilizes strain measurements to optimize stapling and / or cutting of tissue. Background technique [0004] The powered surgical stapling device includes a handle assembly, an adapter assembly including a proximal portion supported on the handle assembly, and a tool assembly supported on a distal portion of the adapter assembly. The tool assembly generally includes a reload assembly and an anvil assembly movably positioned relative to the reload assembly to clamp tissue therebetween. The stapling device may also include strain gauges for measuring properties of the tissue being clamped and / or stapled, such as tissue...
