Patent number: 11944301Abstract: The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and first and second jaws movably coupled to the shaft. The second jaw comprises a cavity for receiving a staple cartridge and a substantially longitudinal reinforcing wall extending through the cavity. The instrument further includes a drive member configured to translate through the end effector to close the jaws and to engage a plurality of staples within the staple cartridge to drive the staples into tissue. The reinforcing wall provides additional support for the staple cartridge to inhibit deformation of the staple cartridge during actuation, thereby improving the staple formation in the tissue. This improves the tissue seal provided by the staples without increasing the overall size of the end effector.Type: GrantFiled: November 22, 2019Date of Patent: April 2, 2024Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Matthew Wixey, Babak Jasemian

Publication number: 20240065690Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position.Type: ApplicationFiled: December 29, 2021Publication date: February 29, 2024Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Babak Jasemian, Tibor Laszlo Hites

Publication number: 20240032921Abstract: A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications.Type: ApplicationFiled: October 6, 2023Publication date: February 1, 2024Inventors: Timothy M. Hopkins, Donald L. Gadberry, Matthew M. Becerra, Babak Jasemian, Gary M. Johnson, Steven E. Decker

Publication number: 20230338025Abstract: A surgical stapling system can include a reload shaft. The shaft can include an elongate tubular member with have a jaw assembly at the distal end thereof and a coupling collar at the proximal end thereof. The shaft assembly also includes an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within the tubular body of the shaft from the proximal end to the distal end. A firing member is connected to the distal end of the drive member such that advancement of the drive beam advances the firing member to close the jaw assemblies and fire staples from a reload positioned in the jaw assembly. The shaft assembly can also include a lockout mechanism to prevent a firing operation on a previously-fired reload or no reload.Type: ApplicationFiled: June 16, 2023Publication date: October 26, 2023Inventors: Babak Jasemian, Steve E. Decker, Atal C. Patel, Erik Nelson, Andrew J. McCarthy, Scott Zimmerman, Timothy M. Hopkins, Joshua M. Schober, Eric J. Weiss, Matthew M. Becerra, Christina N. Reed
