Publication number: 20230371954Abstract: A surgical instrument includes a body, a shaft assembly, a stapling head assembly, an anvil, an anvil adjustment assembly, a trigger, and a lockout assembly. The stapling head assembly is operable to drive an annular array of staples. The anvil is configured to couple with the stapling head assembly. The anvil adjustment assembly includes a translating member, which translates relative to the body to thereby adjust the longitudinal position of the anvil relative to the stapling head assembly. The trigger is operable to actuate the stapling head assembly. The lockout assembly includes an electrically powered braking feature. A method of operating the surgical instrument includes providing the lockout assembly in a first state to permit translation of the translating member. The translating member is then translated. The lockout assembly is then transitioned to a second state to prevent further translation of the translating member.Type: ApplicationFiled: July 28, 2023Publication date: November 23, 2023Inventors: Brian W.

Patent number: 11497491Abstract: A surgical circular stapler has a handle assembly, a shaft, a stapling assembly, a motor, a drive assembly, and a firing assembly. The shaft extends distally from the handle assembly. The stapling assembly is secured to a distal end of the shaft. Longitudinal translation of the firing assembly causes the stapling assembly to drive a plurality of staples in a circular array to secure two lumens of tissue together. The stapling assembly may further drive a blade to sever any excess tissue interior of the circular array of staples. The motor is operable to rotate the drive assembly to thereby translate the firing assembly. A resilient member biases the firing assembly proximally. Through cooperation between the firing assembly and the resilient member, the firing assembly is driven distally and proximally to complete a firing stroke in response to rotation of the drive assembly through a single revolution.Type: GrantFiled: May 15, 2020Date of Patent: November 15, 2022Assignee: Cilag GmbH InternationalInventors: Richard L. Leimbach, Richard F. Schwemberger, John P. Measamer, Johnny H. Alexander, III, Christopher C. Miller, Brian F. DiNardo, Jason M. Rector

Patent number: 10959724Abstract: A surgical circular stapler has a body, shaft, a stapling assembly, a motor, a cam assembly, and a firing assembly. The shaft extends distally from the body. The stapling assembly is secured to a distal end of the shaft. Longitudinal translation of the firing assembly causes the stapling assembly to drive a plurality of staples in a circular array to secure two lumens of tissue together. The stapling assembly may further drive a blade to sever any excess tissue interior of the circular array of staples. The motor is operable to rotate the cam assembly. Rotation of the cam assembly causes longitudinal translation of the firing assembly. A single rotation of the cam assembly is operable to drive the firing assembly from a proximal position to a distal position and back to a proximal position.Type: GrantFiled: August 22, 2018Date of Patent: March 30, 2021Assignee: Ethicon LLCInventors: Christopher C. Miller, John P. Measamer, Brian F. DiNardo, Richard F. Schwemberger, Johnny H. Alexander, III

Patent number: 10888317Abstract: An apparatus includes a body, a motorized end effector, and a control system. The end effector extends distally from the body and comprises a stapling assembly operable to drive staples into tissue. The control system is in communication with the end effector. The control system comprises a motor, a firing trigger, a switch assembly, and a movable member in communication with the firing trigger. A resilient member is engaged with the movable member. The firing trigger and the resilient member are configured to cooperate to move the movable member into engagement with the switch to thereby activate the motor. The switch assembly is configured to couple a power source with the motor to thereby activate the motor in response to actuation of the firing trigger.Type: GrantFiled: February 5, 2018Date of Patent: January 12, 2021Assignee: Ethicon LLCInventors: John P.

Patent number: 10743866Abstract: An anvil introduction system is operable to provide smooth insertion of an anvil of a surgical stapling device through a bodily lumen such as the esophagus. The anvil introduction system is coupled to the anvil and includes a dilation feature. The dilation feature has a collapsed position and an expanded position. The dilation feature may cover staple pockets and an outer edge of the anvil with the dilation feature is in the expanded position. The anvil may be inserted through the bodily lumen with the dilation feature in the expanded position. The dilation feature may then be collapsed in order to complete an end-to-end anastomosis of the bodily lumen.Type: GrantFiled: July 20, 2016Date of Patent: August 18, 2020Assignee: Ethicon LLCInventors: Charles J.
