  • Publication number: 20230414304
    Abstract: An instrument drive unit includes a hub, a motor pack, and an annular member disposed between the hub and the motor pack. The hub and motor pack each have a surface feature. The motor pack is rotatably coupled to the hub. The annular member defines an upper annular channel, and a lower annular channel. The annular member has a stop formed in each of the upper and lower annular channels. Upon the motor pack achieving a threshold amount of rotation relative to the hub, the surface feature of the motor pack abuts the stop of the lower annular channel to rotate the annular member. Upon the annular member achieving a threshold amount of rotation relative to the hub, the stop of the upper annular channel abuts the surface feature of the hub stopping further rotation of the motor pack.

  • Patent number: 11607284
    Abstract: A surgical instrument holder includes a carriage, a housing, and a drive assembly. The carriage is configured for engagement to a surgical robotic arm and for supporting an instrument drive unit. The housing extends from the carriage and defines a channel. The drive assembly includes a pulley, a belt, and an annular member. The pulley is rotatably disposed within the housing and in operable engagement with a motor of the carriage such that actuation of the motor rotates the pulley. The belt is rotatably disposed within the housing and in operable engagement with the pulley such that rotation of the pulley effects rotation of the belt. The annular member is disposed within the channel of the housing and configured for non-rotatable receipt of an instrument drive unit. The annular member is in operable engagement with the belt such that rotation of the belt effects rotation of the annular member.

  • Patent number: 11523509
    Abstract: An integrated circuit includes a nexus and a first, a second, a third, and a fourth circuit board. Each of the first and second circuit boards is coupled to opposing sides of the nexus, and each of the third and fourth circuit boards is coupled to opposing sides of the second circuit board. The integrated circuit is transitionable between a first, open configuration, in which the first, second, third and fourth circuit boards and the nexus are substantially coplanar, and a second configuration, in which the first, second, third and fourth circuit boards and the nexus are coupled to one another to define a cavity therein.

  • Patent number: 11510747
    Abstract: A drape for covering a robotic surgical system includes a first end portion, a second end portion, and an intermediate portion extending between the first and second end portion. The first end portion defines a cavity therein and has an outer surface and an inner surface and defines an inlet through the outer and inner surfaces. The cavity is dimensioned for receipt of an instrument drive unit and is in fluid communication with the inlet. The second end portion has an outer surface and an inner surface and defines an outlet through the outer and inner surfaces. The second end portion defines a cavity therein that is in fluid communication with the outlet. The intermediate portion defines an elongated conduit therethrough dimensioned for receipt of a surgical robotic arm.

  • Patent number: 11406465
    Abstract: A sterile interface module includes a body member that couples a surgical instrument to a robotic surgical assembly, a first drive transfer assembly supported by the body member, and a rotatable collar supported on the body member. The first drive transfer assembly includes a drive coupler and a transfer shaft extending from the drive coupler. The drive coupler is engagable with the robotic surgical assembly and the transfer shaft is engagable with the surgical instrument. The drive coupler and the transfer assembly are robotically movable to operate an end effector of the surgical instrument. The rotatable collar is operably associated with the first drive transfer assembly and is manually movable relative to the body member to manually operate the end effector of the surgical instrument.

  • Publication number: 20220170809
    Abstract: A method of calibrating a torque sensor for a motor with a controller includes determining a gain of the torque sensor, zeroing a torque reading of the torque sensor, accelerating the motor at a known rate, and determining an inertia of the motor in response to accelerating the motor. Zeroing the torque reading occurs when the motor is in an unloaded and unactivated condition and accelerating the motor occurs when the motor is in an unloaded condition.
