Patent number: 11712246Abstract: A method is provided for operating a powered surgical stapler having a motor unit, a controller. and a stapling assembly having a closure member, a staple driver member, and a knife member. The controller receives a user input that indicates a tissue gap to be defined by the stapling assembly in a closed state. Based on the user input, the controller controls the motor unit to actuate the closure member to transition the stapling assembly to the closed state to define the tissue gap and clamp tissue therein. The controller then controls the motor unit to actuate the staple driver member to drive staples into the clamped tissue. In response to determining that the staple driver member has reached a predetermined longitudinal position, the controller controls the motor unit to initiate actuation of the knife member to cut the clamped tissue.Type: GrantFiled: August 24, 2021Date of Patent: August 1, 2023Assignee: Cilag GmbH InternationalInventors: Shane R. Adams, Thomas E. Adams, Nicholas J. Ross, Frederick E. Shelton, IV

Patent number: 11690695Abstract: A surgical device includes a tool assembly and a handle assembly. The tool assembly includes a distal portion including a plurality of staples and an anvil assembly movable relative to the distal portion from an open position to a clamped position. The handle assembly includes an approximation mechanism coupled to the anvil assembly and configured to move the anvil assembly from the open position to the clamped position, a force sensor disposed at a distal end of the surgical device, and a controller. The force sensor is configured to sense a change in resistance indicating a force imparted on compressed tissue and on the approximation mechanism. The controller is configured to receive a signal indicative of a force measured by the force sensor and provide an indication of the sensed force.Type: GrantFiled: June 9, 2021Date of Patent: July 4, 2023Assignee: COVIDIEN LPInventors: David A. Nicholas, Brian L. Holden

Patent number: 11666332Abstract: A surgical instrument comprising a housing, a shaft, an end-effector, a cutting member, and a control circuit is disclosed. The housing comprises a motor. The end-effector comprises a first jaw, a second jaw movable relative to the first jaw, an anvil, and a staple cartridge comprising staples, driver elements, and a sled configured to eject the staples toward the anvil. The sled is movable between a proximal unfired position and a distal fired position through a firing stroke. The cutting member is configured to be advanced distally into the sled by the motor. The control circuit is configured to detect the location of the cutting member, monitor a parameter indicative of a load experienced by the cutting member, determine a threshold value of the parameter based on a portion of the firing stroke, and adjust operation of the motor if the monitored parameter exceeds the determined threshold value.Type: GrantFiled: March 28, 2019Date of Patent: June 6, 2023Assignee: Cilag GmbH InternationalInventors: James R. Giordano, Jeffrey S. Swayze, Frederick E. Shelton, IV

Patent number: 11660163Abstract: A surgical instrument is disclosed including an end effector operable to treat tissue, a shaft extending proximally from the end effector, and a housing assembly extending proximally from the shaft. The housing assembly includes a radio-frequency identification (RFID) scanner and a motor-assembly compartment including a motor assembly interchangeably retained by the motor-assembly compartment in an assembled configuration. The motor assembly is movable relative to the motor-assembly compartment between the assembled configuration and an unassembled configuration. The motor assembly includes a motor configured to drive the end effector to treat the tissue and an RFID tag detectable by the RFID scanner in the assembled configuration. The RFID tag stores motor-assembly information.Type: GrantFiled: June 30, 2019Date of Patent: May 30, 2023Assignee: Cilag GmbH InternationalInventors: Frederick E. Shelton, IV, Kevin M. Fiebig

Patent number: 11660106Abstract: Devices and methods for articulating a distal end of a surgical device are provided. In one exemplary embodiment, the device includes an articulation joint that includes both an inner guide and an outer sleeve. The inner guide includes one channel extending therethrough that receives both a cutting mechanism and a closure band. Further, an outer surface of the inner guide, in conjunction with the outer sleeve, can define two additional channels that each receive an articulation band for articulating an end effector coupled to the articulation joint. The outer surface of the inner guide can include a plurality of ribs that also help define the two additional channels. Further, the outer sleeve can include a plurality of slots formed in it to improve flexibility and stability. Additional configurations of articulation joints, and configurations of components of a surgical device, are also provided, as are methods for using the same.Type: GrantFiled: July 19, 2016Date of Patent: May 30, 2023Assignee: Cilag GmbH InternationalInventors: Barry C.

Patent number: 11653918Abstract: A powered surgical stapling assembly comprising a motor, an end effector, a sensor, a display, and a control circuit is disclosed. The end effector comprises a first jaw and a second jaw movable relative to the first jaw. The end effector is configured to clamp tissue between the first jaw and the second jaw. The sensor is configured to measure a parameter of the tissue clamped within the end effector. The control circuit is configured to monitor the parameter sensed by the sensor and identify when the monitored parameter stabilizes within a stabilization range. The monitored parameter is considered stable when a rate at which the monitored parameter changes falls below a predetermine threshold rate of change. The control circuit is further configured to display to a user when the parameter stabilizes.Type: GrantFiled: September 24, 2019Date of Patent: May 23, 2023Assignee: Cilag GmbH InternationalInventors: Jeffrey S.
