  • Patent number: 11191560
    Abstract: Various exemplary systems, devices, and methods are provided for resisting torque in articulating surgical tools. In general, a surgical tool can include an elongate shaft having at a distal end thereof an end effector configured to engage tissue. The end effector can be configured to articulate relative to the elongate shaft. The surgical tool can include a cutting element configured to translate longitudinally along the end effector to cut the engaged tissue. When the end effector is articulated, the longitudinal translation of the cutting element along the end effector exerts a torque force on the end effector that urges the end effector away from its current angled orientation. The surgical tool can be configured to have a corrective tension or force applied thereto that counteracts the torque force.
