    Abstract: Robotic surgical tools can incorporate a latching mechanism as a secondary fastener to maintain operable coupling between the robotic surgical tool and a mounting fixture of a robotic manipulator. Such robotic surgical tools may comprise: a tool housing, an elongate shaft extending from the tool housing, and a latching mechanism arranged on the elongate shaft. The latching mechanism comprises one or more retention tabs that are biased radially outward with one or more biasing members. The one or more retention tabs are configured to transition between a retracted state and a deployed state under influence of a biasing force supplied by the one or more biasing members. In the deployed state, the one or more retention tabs are positioned to engage an exterior surface of a mounting fixture of a robotic manipulator. In the retracted state, the one or more retention tabs are positioned to disengage from the mounting fixture.

    Abstract: In some aspects, a control algorithm is provided for manipulating a pair of articulation arms configured to control an articulation angle of an end effector of a robotic surgical instrument. Other aspects of the present disclosure focus on the robotic arm system, including the pair of articulation arms coupled to the end effector and guided by independent motors controlled by a control circuit. Each of the articulation arms are designed to exert antagonistic forces competing against each other that are apportioned according to a ratio specified in the control algorithm. The ratio of the antagonistic forces may be used to determine the articulation angle of the head or end effector of the robotic surgical arm.

    Abstract: An apparatus includes a body, a shaft assembly, an end effector, a first acoustic sensor, and a processor. The shaft assembly extends distally from the body. The end effector is located at the distal end of the shaft assembly. The end effector is operable to apply energy to tissue and thereby change a state of the tissue. The first acoustic sensor is configured to pick up sound emitted by tissue. The processor is in communication with the first acoustic sensor. The processor is configured to provide an automated response in response to a signal from the first acoustic sensor indicating a change in the state of the tissue.

    Abstract: A slip ring assembly is usable with a surgical shaft assembly. The slip ring assembly includes a first connector flange comprising a conductor. The slip ring assembly further includes a second connector flange comprising a conductive element in contact with the conductor, wherein the second connector flange is rotatable relative to the first connector flange. In addition, the slip ring assembly also includes a support member, wherein the second connector flange is sandwiched between the first connector flange and the support member, and wherein the support member is configured to apply a load onto the second connector flange to maintain the contact between the conductor and the conductive element.
