Patent number: 11944302Abstract: The present disclosure provides a staple cartridge for a surgical instrument, such as a tissue sealing instrument. The staple cartridge includes a housing and one or more staple assemblies within the housing. The staple assemblies each include one or more staple pushers and associated staples. The staple pushers and housing include coupling elements configured to cooperate with each other to retain the staple assemblies to the housing prior to use in surgery. The coupling elements, along with other components of the cartridge and instrument, result in a smaller staple cartridge relative to conventional devices, allowing for a more compact and maneuverable surgical instrument.Type: GrantFiled: March 2, 2020Date of Patent: April 2, 2024Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Matthew Wixey, Atal Patel

Publication number: 20240023961Abstract: 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. The instrument may further include a stapler cartridge including an annular pin configured to be engaged by a drive member at a an axial position to create a detectable resistance for reload detection by a control unit to identify the type of stapler cartridge present in the surgical stapling instrument.Type: ApplicationFiled: October 4, 2023Publication date: January 25, 2024Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Matthew Wixey, Atal Patel, Babak D.

Publication number: 20220142642Abstract: A stapler reload assembly includes a cartridge body defining a housing to receive staples. The cartridge body has a first side comprising a plurality of staple apertures configured to eject staples housed in the cartridge body. The cartridge body has a second side, opposite the first side, comprising a plurality of pusher apertures through which staple pushers of the cartridge body are accessible. A staple retainer is removably coupled to the first side of the cartridge body and at least partially covers the plurality of staple apertures. A cover is removably coupled to and at least partially covers the plurality of pusher apertures. Devices and methods relate to stapler reload assemblies.Type: ApplicationFiled: February 26, 2020Publication date: May 12, 2022Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Austin de MAILLÉ, Jorge Alberto Treviño BLANCO, Robert HUBLER, Babak D.

Publication number: 20220071632Abstract: The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and an end effector. The end effector includes a first jaw and a second jaw that includes a staple cartridge with a plurality of staples for engaging tissue. The instrument further includes a drive member for closing the jaws and engaging the staples, and an actuation mechanism, such as a coil, in contact with the drive member. The actuation mechanism is configured to translate the drive member distally through the first jaw (instead of through the staple cartridge as in conventional surgical stapling instruments). Eliminating the internal channel for the actuation coil from the staple cartridge provides more space in the cartridge for the staples, allowing for the use of taller staples and/or a more compact and maneuverable instrument.Type: ApplicationFiled: December 6, 2019Publication date: March 10, 2022Inventors: Atal PATEL, Matt WIXEY, Ashley WELLMAN

Patent number: 10595866Abstract: A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a repeatable open and close mode, a second rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a third rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include a rotational mechanism arranged to discretely position the rotatable actuation shaft in one of the rotational orientations. The rotational mechanism can be arranged for single handed operation such as by including a slidable switch or selector to rotate the actuation shaft.Type: GrantFiled: May 18, 2017Date of Patent: March 24, 2020Assignee: Applied Medical Resources CorporationInventors: Atal Patel, Jonathan Covach, Christina N.

Publication number: 20110082389Abstract: A measuring system may provide quantitative information relating to condition of cartilage. Negative pressure may be applied to cartilage to induce flow of fluid from or through the cartilage. A level of negative pressure needed to induce a particular flow of the fluid may be employed to provide a quantitative indicia of cartilage condition. An averaged level of negative pressure measured over a period of time may be used to calculate hydraulic resistance of the cartilage.Type: ApplicationFiled: October 6, 2010Publication date: April 7, 2011Applicants: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, SYNTHASOME, INC.Inventors: WILLIAM JOSEPH McCARTY, PRIYA SUNDARAMURTHY, CARYN URBANCZYK, ATAL PATEL, JACOB HAHR, ROBERT L.
