Patent number: 11937815Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob when an instrument shaft is engaged with the handle. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler and can provide certain motor drive profiles for predetermined positions of the stapler. The powered handle can include a manual return mechanism.Type: GrantFiled: June 3, 2021Date of Patent: March 26, 2024Assignee: Applied Medical Resources CorporationInventors: Erik D. Nelson, Jonathan R. Nash, Timothy M. Hopkins, Kevin Hudson, Andy Pham, Zachary W. Gyugyi, Joshua A. Spalding, Christian A Halvorsen

Publication number: 20230338026Abstract: A powered handle for a surgical stapler has a drive system including an electric motor. The powered handle includes a shaft recognition mechanism such that when a reload shaft for use with the surgical stapler is installed, a control system can actuate the drive system with the recognized shaft. The powered handle further comprises a LED light ring driven by a light control scheme to display a handle status. The control system also includes a startup module to assess hardware and control system performance before use. The startup module assesses different criteria depending on whether the handle is new, previously used, or previously reset. The control system of the powered handle further includes a lockout module configured to identify when a lockout has been encountered. The lockout module applies different criteria depending on whether the motor is operating at a maximum speed state or less than a maximum speed state.Type: ApplicationFiled: June 21, 2023Publication date: October 26, 2023Inventors: Kevin Hudson, Andy Pham, Jonathan R. Nash, Zachary W. Gyugyi, Travis Bautista, Jonathan Von Stein, Ata Kiraz, Eric J. Weiss

Publication number: 20210290234Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob when an instrument shaft is engaged with the handle. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler and can provide certain motor drive profiles for predetermined positions of the stapler. The powered handle can include a manual return mechanism.Type: ApplicationFiled: June 3, 2021Publication date: September 23, 2021Inventors: Erik D. Nelson, Jonathan R. Nash, Timothy M.
