摘要:
A robotic system for minimally invasive surgery includes a surgical tool and a docking station for restraining movement of the surgical tool to four degrees of freedom about an incision point in a patient. The docking station includes a plurality of actuators for moving the surgical tool relative to the incision in the patient, and a controller operably connected to the actuators so that movement of the surgical tool may be collaboratively controllable both actively by the controller and manually by a surgeon. Desirably, the surgical tool and the docking station are releasably attachable together. Also disclosed is a computer implemented method employing a first docking station attachable to a suturing surgical tool and a second docking station attachable to gripping surgical tool for autonomously tying a knot in suturing.

A system for providing substantially stable haptics includes at least one computer configured to identify a first subset and a second subset of haptic interaction geometric primitives for a virtual tool. The computer is configured to determine based on the first subset, haptic forces in a first subspace. The computer is also configured to determine based on the second subset, haptic forces in a second subspace different from the first subspace.

A computer-assisted surgery system may have a robotic arm including a surgical tool and a processor communicatively connected to the robotic arm. The processor may be configured to receive, from a neural monitor, a signal indicative of a distance between the surgical tool and a portion of a patient's anatomy including nervous tissue. The processor may be further configured to generate a command for altering a degree to which the robotic arm resists movement based on the signal received from the neural monitor; and send the command to the robotic arm.

A tool includes a housing including a receiving portion configured to receive at least a portion of an operating member so as to permit rotation of the operating member relative to the housing while constraining movement of the operating member in a radial direction of the operating member. The tool also includes a coupling device disposed on the housing and configured to couple the operating member to the housing so as to permit rotation of the operating member relative to the housing. The coupling device includes a retaining member configured to engage the operating member to constrain movement of the operating member relative to the housing in a longitudinal direction of the operating member. The retaining member is configured to rotate relative to the housing.

Systems and methods for robotic surgery are disclosed. In one embodiment, a system comprises a controller configured to control actuation of at least one servo motor; a surgical instrument configured to be movable in a workspace controlled, at least in part, by actuation of the at least one servo motor; and a mechanical tracker linkage coupled between the elongate instrument and a portion of skeletal anatomy of a patient, the tracker linkage comprising one or more joints associated with one or more joint rotation sensors and being configured to send joint signals to the controller; wherein the controller controls positioning of the instrument based at least in part upon the joint signals received from the mechanical tracker.

A device can be assembled by a coupling. The device includes first and second body members and positioning structure. The first and second body members are designed to be coupled relative to each other. The positioning structure is designed to provide an interface between the first and second body members, and to position the first and second body members relative to each other via first, second, and third contact areas. The first, second, and third contact areas are each substantially linear and are collectively configured to receive loads, and to limit positioning of the first and second body members relative to each other with regard to five degrees of freedom. A fourth contact area between the first and second body members is designed to limit positioning of the first and second body members relative to each other in a sixth degree of freedom, in a first translational direction.

A method and apparatus are disclosed for constraining motion of an end-effector in space. In one embodiment, the apparatus may include a mechanical positioner and first and second stops. The first and second stops may be controllable by a drive mechanism to constrain movement of the mechanical positioner and thereby to constrain the ability of a user to manipulate an end-effector outside a predetermined range of motion. The first and second stops may be further controllable by the drive mechanism to permit movement of the end-effector within the predetermined range of motion.

Described are computer-based methods and apparatuses, including computer program products, for inertially tracked objects with a kinematic coupling. A tracked pose of a first inertial measurement unit (IMU) is determined, wherein the first IMU is mounted to a first object. The tracked pose of the first IMU is reset while the first object is in a first reproducible reference pose with a second object.

In one embodiment, a robotic surgery system comprises a handheld manipulator configured to be manually moved in a global coordinate system relative to the bone, the handheld manipulator comprising a bone cutting tool comprising an end effector portion, a frame assembly, and a motion compensation assembly movably coupled to the frame assembly and bone cutting tool. A controller may be operatively coupled to the manipulator and configured to operate one or more actuators within the frame assembly to cause the motion compensation assembly to automatically move relative to the frame assembly to defeat aberrant movement of the bone cutting tool that would place the end effector portion of the tool out of a desired bone cutting envelope that is based at least in part upon one or more images of the bone, while allowing the bone cutting tool to continue cutting one or more portions of the bone.
