Publication number: 20240023967Abstract: A surgical device includes a handle assembly having a power source; a motor coupled to the power source; and a controller configured to control the motor. The surgical device also includes an adapter assembly configured to selectively couple to the handle assembly; a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of fasteners; and an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload. The controller is further configured to control the motor to move the anvil assembly from a starting position to a compressed position thereby compressing tissue at a target clamping force between the anvil assembly and the reload.Type: ApplicationFiled: December 12, 2021Publication date: January 25, 2024Inventors: David E.

Publication number: 20230389927Abstract: Inserts and features to reduce or prevent spline crash in surgical staplers and/or to minimize damage resulting from spline crash in surgical staplers. An insert for a surgical stapler includes a body and spline covers. The body is configured to fit within a bore of a shell assembly and the spline covers extend inward from the body. Each of the spline covers are sized and dimensioned to cap a distal portion of splines of the shell assembly. A shell assembly for a surgical stapler includes shell splines that are disposed on an inner wall of an inner housing portion that defines a bore. The shell splines include a lead spline that has a leading end positioned distal of a leading end of each of the other shell splines.Type: ApplicationFiled: August 17, 2023Publication date: December 7, 2023Inventors: Joseph M.

Publication number: 20230355241Abstract: 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.Type: ApplicationFiled: May 17, 2023Publication date: November 9, 2023Inventors: Haley Strassner, David E.

Patent number: 11723664Abstract: A surgical device includes a handle assembly having a controller and a motor. The surgical device also includes an adapter assembly having: a tubular housing having a proximal end portion configured to couple to the handle assembly and a distal end portion; and an actuation assembly configured to couple to the motor. The surgical further includes a reload configured to couple to the distal end portion of the adapter assembly; and an anvil assembly including an anvil head pivotally coupled to an anvil shaft, the anvil assembly configured to couple to the actuation assembly and the reload. The controller of the surgical device is configured to control the motor to actuate the actuation assembly to move the anvil assembly in a distal direction for a distance based on a dimension of one of the reload or the anvil head, thereby pivoting the anvil head relative to the anvil shaft while maintaining engagement of the anvil assembly to the reload.Type: GrantFiled: December 16, 2021Date of Patent: August 15, 2023Assignee: Covidien LPInventors: Joseph Guerrera, Steven H.
