Patent number: 12103102Abstract: A method and apparatus for joining using friction and current, wherein the friction/current joining apparatus includes a friction device, a forging device, an electrical current source, and a programmable controller, as well as workpiece holders for the workpieces to be joined. The friction/current joining apparatus is controlled such that, in a contacting phase, the workpieces are initially moved along a process axis, and their mutually facing joining surfaces oriented transverse to a common process axis are brought into contact. In a grinding phase, while subjected to contact pressure by mutual relative movement, the joining surfaces, are ground together and made smooth.Type: GrantFiled: April 24, 2020Date of Patent: October 1, 2024Assignee: KUKA Deutschland GmbHInventors: Jörg Herrich, Stefan Habersetzer, Klaus Schneider, Andreas Burger, Andy Pham

Publication number: 20240285276Abstract: 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: March 20, 2024Publication date: August 29, 2024Inventors: Erik D. Nelson, Jonathan R. Nash, Timothy M. Hopkins, Kevin Hudson, Andy Pham, Zachary W. Gyugyi, Joshua A. Spaiding, Chriatian 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
