Provided is a robotic system that includes a surgical instrument with a wrist including an elongate shaft extending between a proximal end and a distal end, a wrist extending from the distal end of the elongate shaft, and an end effector extending from the wrist. The end effector may include a first jaw and a second jaw, the first and second jaw being moveable between an open position in which ends of the jaws are separated from each other, and a closed position in which the ends of the jaws are closer to each other as compared to the open position. The surgical instrument may also include at least one rotary cutter extending from the wrist and positioned at least partially within a recess formed in a face of the first jaw.

A transport apparatus may include a patient bed unit for supporting the patient; a transferring unit for moving the patient bed unit along a first direction of the MRI device; and an elevating module for moving the patient bed unit along a second direction of the MRI device.

The present invention relates to a scissors lift comprising a bottom frame, a top frame and a scissors mechanism arranged between said bottom frame and said top frame to displace said bottom frame and said top frame relative to each other by transfer of an actuation force. The scissors mechanism comprises a central hollow scissors arm delimited between opposite scissors arm surfaces, wherein said central hollow scissors arm has a bottom pivotal connection connecting it to said bottom frame and a top pivotal connection connecting it to said top frame. Further, the mechanism comprises two passive scissors arms being pivotally connected to said bottom frame and pivotally connected to said top frame. Each of said two passive scissors arms are pivotally connected to said central hollow scissors arm on said opposite scissors arm surfaces of said central hollow scissors arm. Further, the scissors lift comprises a motor providing said actuation force, said motor located between said opposite scissors arm surfaces of said central hollow scissors arm. Thereby, the motor may be protected and at least partially enclosed by the scissors lift and even by the central hollow scissors arm, allowing a safer and/or more easily maintained scissors lift.

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.

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 device and system for supporting a patient or an object in an examination is provided. The supporting system may include a portion for supporting the body of a patient and/or a head supporting device. The portion for supporting the body may move in one or more directions. The head supporting device may be adjust to meet requirements of imaging when the patient or the object is supine or prone.
