Manipulator

A manipulator comprises an operation command unit provided with an attitude adjusting unit and an end effector control unit, a connecting unit having one end connected to the operation command unit, a working unit connected to the other end of the connecting unit and provided with an end effector and a support unit supporting the end effector for motions, and a control unit that transmits an operation command provided by the attitude adjusting unit to the support unit to adjust the attitude of the end effector and transmits an operation command provided by the end effector control unit to the end effector to operate the end effector. The support unit includes a first joint capable of turning about a first axis perpendicular to the center axis of the connecting unit, and a second joint capable of turning about a second axis perpendicular to the first axis. The end effector can be turned for rolling about an axis substantially parallel to the second axis of the second joint. The attitude adjusting unit has a third joint having a third axis perpendicular to the center line of the connecting unit. The end effector control unit is formed such that the fingers of an operator gripping operating members included in the end effector control unit extend substantially in parallel to the fourth axis.

Surgical robotic tools, data architecture, and use

InactiveUS6866671B2Avoids frequent delayMechanical apparatusDiagnosticsRobotic systemsEngineering
Robotic surgical tools, systems, and methods for preparing for and performing robotic surgery include a memory mounted on the tool. The memory can perform a number of functions when the tool is loaded on the tool manipulator: first, the memory can provide a signal verifying that the tool is compatible with that particular robotic system. Secondly, the tool memory may identify the tool-type to the robotic system so that the robotic system can reconfigure its programming. Thirdly, the memory of the tool may indicate tool-specific information, including measured calibration offsets indicating misalignment of the tool drive system, tool life data, or the like. This information may be stored in a read only memory (ROM), or in a nonvolatile memory which can be written to only a single time. The invention further provides improved engagement structures for coupling robotic surgical tools with manipulator structures.

Tool grip calibration for robotic surgery

ActiveUS7386365B2Limited tool lifeStringent manufacturing toleranceProgramme-controlled manipulatorDiagnosticsEngineeringActuator
Telerobotic, telesurgical, and surgical robotic devices, systems, and methods selectively calibrate end effector jaws by bringing the jaw elements into engagement with each other. Commanded torque signals may bring the end effector elements into engagement while monitoring the resulting position of a drive system, optionally using a second derivative of the torque / position relationship so as to identify an end effector engagement position. Calibration can allow the end effector engagement position to correspond to a nominal closed position of an input handle by compensating for wear on the end effector, the end effector drive system, then manipulator, the manipulator drive system, the manipulator / end effector interfacing, and manufacturing tolerances.

Medical manipulator and method of controlling the same

A medical master / slave manipulator is excellent in operability and capable of reducing burden on the operator. The medical master / slave manipulator includes a master unit provided with an operation control portion, a slave unit provided with a working device, an interlocking mechanism interlocking the slave unit with the master unit, an orientation difference measuring mechanism for measuring the orientation difference between the orientation of the master unit and that of the slave unit, and a control mechanism for controlling the slave unit to adjust the orientation of the slave unit to that of the master unit so that the orientation difference is reduced to zero in a transient master / slave operation mode in which an operation mode changes from an unrestricted operation mode to a master / slave operation mode.

Medical manipulator

A medical manipulator includes an operating unit and a working unit. The operating unit has an actuator block with motors housed therein. The working unit is detachably mounted on the actuator block by a coupler. The working unit comprises a joint shaft that extends from the coupler, and a distal-end working unit mounted on a distal end of the joint shaft. The distal-end working unit has three axes, including a yaw axis, a roll axis about which the distal-end working unit is rotatable and which is positioned closer to a distal end of the distal-end working unit than the yaw axis, and a gripper axis about which a gripper is openable and closable and which is positioned on the distal end. The distal-end working unit can be operated about the roll axis by a motor, which is positioned closer to the distal end than the yaw axis.

Systems and methods for safe compliant insertion and hybrid force/motion telemanipulation of continuum robots

Methods and systems are described for controlling movement of a continuum robot that includes a plurality of independently controlled segments along the length of the continuum robot. The continuum robot is inserted into a cavity of unknown dimensions or shape. A plurality of forces acting upon the continuum robot by the surrounding cavity are estimated. A positioning command indicating a desired movement of the distal end of the continuum robot is received from a manipulator control. The desired movement is augmented based, at least in part, on the estimated plurality of forces acting on the continuum robot such that movement is restricted to within safe boundaries of the surrounding cavity. The positioning of the continuum robot is then adjusted based on the augmented desired movement.

Medical robotic system with coupled control modes

In a coupled control mode, the surgeon directly controls movement of an associated slave manipulator with an input device while indirectly controlling movement of one or more non-associated slave manipulators, in response to commanded motion of the directly controlled slave manipulator, to achieve a secondary objective. By automatically performing secondary tasks through coupled control modes, the system's usability is enhanced by reducing the surgeon's need to switch to another direct mode to manually achieve the desired secondary objective. Thus, coupled control modes allow the surgeon to better focus on performing medical procedures and to pay less attention to managing the system.
