  • Patent number: 11116508
    Abstract: An apparatus includes a body, a motor, a shaft, a stapling assembly, and an electrical potential shifting device. The body includes a firing switch configured to generate a motor drive signal including at least one of a motor activation signal portion or a motor deactivation signal portion. The motor includes a first power terminal and a second power terminal which define an electrical potential energy differential therebetween. The motor is configured to selectively activate and deactivate in response to the electrical potential energy differential. The first power terminal is coupled to a power supply and the second power terminal is coupled to the electrical potential shifting device. The electrical potential shifting device increases the electrical potential energy differential of the motor in response to detecting the motor activation signal portion and decreases the electrical potential energy of the motor in response to detecting the motor deactivation signal portion.

  • Patent number: 10959727
    Abstract: A surgical tool assembly. A surgical end effector is movably coupled to a shaft assembly by an articulation joint that is configured to facilitate selective articulation of the surgical end effector relative to the shaft assembly. The shaft assembly includes a proximal end portion and a distal end portion. The distal end portion is operably coupled to the articulation joint. An elongate notch is provided in the distal end portion and is located on one lateral side of a shaft axis that is defined by the shaft assembly. The shaft assembly may be configured to prevent the distal end portion from buckling when an axial actuation motion is applied to the proximal end.
