A surgical positioning cart configured to support a surgical robotic device thereon a distal side configured to face a surgical entry site of a patient, comprises a base movable at least along a horizontal reference plane, a head pivotable relative to the horizontal plane to define therewith different inclination angles at least in a plane comprising vertical and longitudinal axes of the cart; a slider configured to fixedly receive at least a portion of the surgical robotic device thereon and mounted to the head so as to be pivotable therewith and be movable relative thereto at least along the longitudinal axis; and a neck connecting between the base and the head pivotally mounted thereto, having an adjustable height defined by a length of the neck in the vertical direction.

A rotary tool includes a tool body and a powered rotary cutting tooltip that is oriented and positioned relative to the tool body by a plurality of processor-controlled actuators that provide degrees of freedom. The processor uses a surgical tracking system to identify the pose of the tool body and the tooltip relative to a patient's anatomy and controls the actuators to maintain the tooltip within a predetermined cutting plan to compensate for deviation of a surgeon's hand or a robotic arm controlling the tool body during a cutting operation.

The invention relates to a surgical system for cutting an anatomical structure (F, T) of a patient according to at least one target plane defined in a coordinate system of the anatomical structure, comprising: i) a robotic device (100) comprising: —a cutting tool, —an actuation unit (4) comprising from three to five motorized degrees of freedom, said actuation unit comprising at least one portion having a parallel architecture comprising a base (40) and a platform (41) selectively orientable relative to the base (40) according to at least two of said motorized degrees of freedom, —a planar mechanism (24) connecting a terminal part of the actuation unit (4) to the cutting tool (2), ii) a passive articulated lockable holding arm (51) supporting the actuation unit, iii) a tracking unit (200) configured to determine in real time the pose of the cutting plane with respect to the coordinate system of the anatomical structure, iv) a control unit (300) configured to determine the pose of the cutting plane with respect to the target plane, to detect whether the cutting plane can be aligned with one target plane without changing the pose of the actuation unit, the control unit being further configured to, if the cutting plane cannot be aligned with the target plane, compute indication to a user to reposition the actuation unit with respect to the anatomical structure and, if the cutting plane can be aligned with the target plane, control the actuation unit (4) so as to bring the cutting plane into alignment with the target plane, v) a user interface coupled to the control unit, configured to indicate directions to a user to position the actuation unit with respect to the anatomical structure according to a pose allowing aligning the cutting plane with the target plane.

A surgical robotic arm (100) includes a presurgical positioning assembly (10), a telecentric manipulating assembly (20) and an executing assembly (30); the telecentric manipulating assembly (20) includes a static platform (21), a first movable platform (22) and a plurality of first telescopic elements (23) disposed between the static platform (21) and the first movable platform (22); the executing assembly (30) has a preset telecentric fixed point; coordinated extension and retraction among the plurality of first telescopic elements (23) is capable of controlling the first movable platform (22) to move relative to the static platform (21) and drive the executing assembly (30) to extend and retract and swing; a swing center of the executing assembly (30) is the telecentric fixed point; and a telescopic path of the executing assembly (30) passes through the telecentric fixed point.

A handheld microsurgical robot according to an embodiment of the present disclosure includes a tool, and a driving mechanism configured to detachably fix the tool and operate the tool, wherein the driving mechanism includes a platform supporting the tool, a plurality of driving assemblies connected to the platform and configured to operate the platform; and a base configured to fix the plurality of driving assemblies, wherein each of the plurality of driving assemblies is capable of a linear motion with respect to the base and is capable of a rotational motion with respect to the base, wherein a position and an angle of the platform with respect to the base are controlled by the linear motion of each of the plurality of driving assemblies.

Disclosed herein are embodiments of methods of using stabilizers for use in delivering a replacement heart valve. The stabilizers can receive a portion of a delivery system, such as a handle, to prevent unwanted motion of the delivery system. The stabilizer can include a linear actuator for adjusting a position of the delivery system once held within the stabilizer.

A driving device includes a corrector, an actuator, and a position sensor. The actuator includes a nut connected to a movable part, a ball screw shaft onto which the nut is screwed, and a pulse motor that drives to rotate the ball screw shaft. The corrector includes a correction amount map in which a position correction amount for calibrating a predictable error is mapped for each position of the movable part. The corrector estimates an ideal movement position to which the movable part moves based on a command signal and refers to the correction amount map to calculate the position correction amount corresponding to a present position detected by the position sensor. The corrector generates a correction signal by correcting the command signal so as to reduce the difference between a corrected present position obtained by correcting the present position by the position correction amount and the ideal movement position.

A medical device is provided. The medical device includes a parallel manipulator. The parallel manipulator has an end platform coupled to a surgical tool and a base platform coupled to a machine module. The machine module is coupled to the surgical tool through a transmission shaft disposed between the end platform and the base platform. The transmission shaft has a transmission yoke, a runner, a first rod coupled to the transmission yoke, a second rod coupled to the runner, and a universal joint coupled between the first rod and the second rod.

A device comprising a first stent, a plurality of flexible links coupled to the first stent, a plurality of compliant links, each compliant link coupled to at least one of the flexible links, a second stent coupled to the plurality of compliant links, wherein the plurality of flexible links and the plurality of compliant links are configured to steer one or more of the first stent and the second stent in a plurality of degrees of freedom.
