Abstract:
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.
Abstract:
In a system, a first closed region specifying unit specifies a first closed region on a screen for enclosing an imaged obstacle in a first image, and a first projection area determining unit determines a first virtual projection area by extending a first closed region in a first orientation. A second closed region specifying unit specifies a second closed region on the screen. The second closed region encloses the imaged obstacle in the second image. A second projection area determining unit determines a second virtual projection area by extending the second closed region in a second orientation. An establishing unit establishes an overlap region between the first and second projection areas as the no-entry zone for the robot.
Abstract:
A robot control unit (30) comprises: a setting means (40) for setting operating ranges of each shaft and a working tool of the robot (20); a storage means (33) for storing an inertial running distance of the robot decided by at least one of the operating speed of the robot and the weight of the working tool; and an arriving range calculation means (36) for calculating an arriving range to which the robot arrives according to the operating range, which has been set by the setting means, and the inertial running distance stored by the storage means. Due to the foregoing, while consideration is being given to the inertial running distance of a robot, the arriving range of the robot is made. Further, a display means (41) for displaying the arriving range may be provided. In the case where each shaft of the robot and the working tool deviate from the operating range, a stopping means (34) for stopping the robot may be provided.
Abstract:
A surgical apparatus includes a surgical device, configured to be manipulated by a user to perform a procedure on a patient, and a computer system. The computer system is programmed to implement control parameters for controlling the surgical device to provide at least one of haptic guidance to the user and a limit on user manipulation of the surgical device, based on a relationship between an anatomy of the patient and at least one of a position, an orientation, a velocity, and an acceleration of a portion of the surgical device, and to adjust the control parameters in response to movement of the anatomy during the procedure.
Abstract:
A human-robot cooperation (HRC) workstation has a programmable industrial robot (4) and a manual working area (14) for a worker (5) in a region surrounding the industrial robot (4). In the HRC workstation (1), the working areas of the industrial robot (4) and the worker (5) overlap. Contact between the worker (5) and the industrial robot (4) is possible. The workstation (1) is divided into a plurality of different zones (17, 18, 19, 20) having differently high levels of risk of hazard from the industrial robot (4) for the worker (5). The industrial robot (4) is suitable for human-robot cooperation.
Abstract:
A robot system comprises a robot provided with a robot arm and a robot hand, and a control device for controlling the motion of the robot, wherein a permitted area where a teaching operation for the robot hand should be permitted is preset within a maximum area which the robot hand can reach. The control device is provided with a judging part which judges if the robot hand as a whole is present in the permitted area, based on robot hand position information, and a teaching operation restricting part which permits a teaching operation for the robot hand when it is judged that the robot hand as a whole is present in the permitted area and prohibits a teaching operation for the robot hand when it is judged that the robot hand as a whole is not present in the permitted area.

Abstract:
A method for joint replacement is provided. A representation of a first bone is created, and a representation of a second bone is created. Bone preparation for implanting a first implant on the first bone is planned. The first bone to receive the first implant is prepared by manipulating a surgical tool to sculpt the first bone. Bone preparation for implanting a second implant on the second bone after preparing the first bone is planned. The second bone to receive the second implant is prepared by manipulating the surgical tool to sculpt the second bone.
Abstract:
In a master-slave manipulator system capable of presenting an obstacle and a limit to an operating range as a force feed-back with no use of a motor in an operation input device and having high reliability, a small size and good operability, the system comprises a manipulator having an arm, an operation input device for moving the arm of the manipulator, and a controller for controlling the manipulator and the operation input device, and the operation input device is provided on joints with a mode change-over mechanism having three modes: of which, in a first mode, power is not transmitted; in a second mode, power is transmitted in one direction and is not transmitted in a reverse direction thereof; and in a third mode, power is transmitted in the reverse direction and is not transmitted in the one direction, selecting one of the above modes and changing over from one mode to the selected mode.
Abstract:
In one aspect, the invention relates to a method for generating a haptic penalty force, including in one embodiment, the steps of: defining a primary proxy position; defining a secondary proxy position; defining a HIP position; generating a first force in response to the primary proxy position and the HIP position and generating a second force in response to the secondary proxy position and the HIP position.
