A positioning frame for supporting a patient to facilitate different surgical approaches to the spine includes a main support beam, first and second support structures, a torso-lift support, and a pelvic-tilt support. The main support beam has a first end, a second end, and a length extending between the first and second ends. The main support beam defines an axis of rotation relative to at least a first support structure and a second support structure, and the axis of rotation substantially corresponds to a cranial-caudal axis of the patient when the patient is supported on the positioning frame. The first and second support structures support the main support beam, and space the main support beam from the ground. The torso-lift support is attached to the main support beam, and is configured to pivot a chest support plate between at least a first position and a second position to move the torso of the patient between an unlifted position and a lifted position. The pelvic-tilt support is attached to the main support beam, and is configured to support the thighs and the lower legs of the patient. Portions of the pelvic-tilt support are pivotal with respect to one another to facilitate adjustment of the hips of the patient.

Certain aspects relate to systems and techniques for surgical robotic arm admittance control. In one aspect, there is provided a system including a robotic arm and a processor. The processor may be configured to determine a force at a reference point on the robotic arm based on an output of a torque sensor and receive an indication of a direction of movement of the reference point. The processor may also determine that a component of the force is in the same direction as the direction of movement of the reference point, generate at least one parameter indicative of a target resistance to movement of the robotic arm, and control the motor, based on the at least one parameter, to move the robotic arm in accordance with the target resistance.

A surgical tool comprising a drive housing having first and second ends, a lead screw extending between the first and second ends and rotatably coupled to the first end at a drive input, a carriage mounted to the lead screw at a carriage nut and movable within the drive housing between the first and second ends, and an instrument driver arranged at an end of a robotic arm and matable with the first end. A drive output is matable with the drive input such that rotation of the drive output correspondingly rotates the drive input and the lead screw to thereby translate the carriage nut along the lead screw. A fin may be connected to the carriage and accessible by a user from an exterior of the drive housing to manually translate the carriage along the lead screw and thereby backdrive the drive output.

A surgical tool comprising a drive housing having a first end and a second end, a spline extending between the first and second ends and being rotatably coupled to the first end at a drive input, a drive gear coupled to and rotatable with the spline, a carriage movably mounted to the spline and housing an activating mechanism operatively coupled to the drive gear such that rotation of the spline actuates the activating mechanism, and a bailout mechanism arranged at the second end. The bailout mechanism may include a lever that is movable relative to the spline, from a first position, where the spline is disengaged from the lever, to a second position, where the spline engages the lever such that rotation of the lever correspondingly rotates the spline.

A surgical frame and method for use thereof is provided. The surgical frame is capable of reconfiguration before, during, or after surgery using a moveable main beam supporting a patient thereon. The surgical frame includes a translating lower beam that is moveable between at least a first lateral position and a second lateral position, and a linkage and/or surgical equipment supportively and moveably attached to the translating lower beam or interconnected with the translating lower beam via the linkage. The linkage and/or the surgical equipment are moveable between a first position at or adjacent a first end of the translating lower beam and a second position at or adjacent a second end of the translating lower beam. The translating lower beam is used to join a first support portion and a second support portion of the surgical frame to one another, and movement of the translating lower beam affords access to a patient receiving area. A linear movement mechanism can be used to facilitate movement of the linkage and/or the surgical equipment along the translating lower beam to avoid interference with the main beam or the translating lower beam.

An apparatus for transferring a supine patient to a prone position on a patient support structure, and for rotating such a prone patient between prone and supine positions without removing the patient from the patient support structure.

Robotic medical systems can enable manipulation of a single robotic arm and have other robotic arms follow its motion. A robotic medical system can include a first robotic arm for holding a first medical tool and a second robotic arm for holding a second medical tool separated from the first medical tool. The robotic medical system can be configured to obtain data corresponding to movement of the first robotic arm and cause movement of the second robotic arm according to the movement of the first robotic arm.
