摘要:
A method and system for providing control that include providing a workpiece that includes a target shape, providing a cutting tool, providing a 3-D image associated with the workpiece, identifying the target shape within the workpiece image, providing a 3-D image associated with the cutting tool, registering the workpiece with the workpiece image, registering the cutting tool with the cutting tool image, tracking at least one of the workpiece and the cutting tool, transforming the tracking data based on image coordinates to determine a relationship between the workpiece and the cutting tool, and, based on the relationship, providing a control to the cutting tool. In one embodiment, the workpiece image can be represented as volume pixels (voxels) that can be classified and/or reclassified based on target shape, waste, and/or workpiece.

A manipulator-device controlling method of the present invention includes: a step (SA1) of receiving manipulation signals for manipulators; a step (SA2) of calculating a target position of a joint on the basis of the manipulation signals; steps (SA3, SA4, and SA5) of calculating a maximum distance between the manipulators when the joint is assumed to be placed at the target position; a step (SA6) of comparing the maximum distance with a predetermined threshold; a step (SA7) of moving the joint to the target position in the case in which the maximum distance is equal to or less than the predetermined threshold; and a step (SA8) of stopping the movement of the joint in the case in which the maximum distance is greater than the predetermined threshold.

The invention relates to a robotic system for moving a shapeable instrument like a shapeable catheter within an object like a person. The system (1) comprises a robotic device (2, 3) for modifying the shape of the instrument (2) and moving the instrument within the object (7) and a control unit (4) for controlling the robotic device based on structure information like a roadmap, a target position and shape and an actual position and shape such that the instrument is moved and the shape of the instrument is modified from the actual position and shape to the target position and shape. Since the control unit considers structure information while controlling the robotic device, the navigation of the instrument can be automatically performed under consideration of knowledge about regions within the object, through which the instrument is navigatable. The navigation may therefore be performed without or with few user interactions only.

The invention has for its object to provide a manipulator and manipulator system in which a dynamic surplus is rapidly removed and a moving part actuates rapidly in association with the operation of an operating part. The manipulator 1 is characterized by including an operating part 2 operated by an operator, a moving part 3 operated by the operating part 2, a transmitting part 4 for coupling the operating part 2 to the moving part 3 to transmit driving force of the operating part 2 to the moving part 3, a transmission compensating part 6 for making up for a dynamic surplus occurring in the transmitting part 4 in association with the operation of the operating part 2, an input part 8 for acquiring a state of at least one of the operating 3, moving 3 and transmitting part 4, and a control unit 91 for controlling the transmission compensating part 6 depending on the state acquired by the input part 8.

A manipulator includes: a drive section (41B) which electrically drives a joint (53a-53d); an instruction input section (44B) which executes instruction input; a control section (42B) which generates a driving signal in response to the instruction input (44B); a sensor (60a-60c) which detects an operation status of the joint (53a-53d) or the drive section in time series; a setting section (14B) which sets an allowable operation range of the drive section (41B); a determination section (12B) which determines whether an operation status signal including a detection signal is within the allowable operation range; and a replacement section (16B) which, in a case when the operation status signal is determined as deviating from the allowable operation range, replaces the detection signal with a previous detection signal acquired just before the determination of deviance in order to generate a driving signal.

A system for providing realistic sensation within a simulation system by providing tactile (haptic) feedback to a user. The system includes an engageable practice tool that the user engages and a mechanical simulation apparatus coupled to the practice tool. The mechanical simulation apparatus includes a ground member (46), a mechanical linkage (38) rotatably coupled to the ground member (47), a linear axis member coupled to the practice tool and the mechanical linkage (38), at least four actuators (62, 64, 66, 70) coupled to the ground member, sensors (65, 67, 69) for sensing movement of the actuators, and at least three cables in contact with the at least four (actuators ) (65, 64, 66, 70) and coupled to the mechanical linkage (38). An interface device is coupled to the simulation apparatus and a host computer (20) is coupled to the interface device (14) for implementing an application program. The application program provides signals for the actuators (62, 64, 66, 70) to move the cables (130) and thereby move the mechanical linkage (38).

摘要:
A surgical system, adapted to operate with at least one surgical device, has a handpiece containing a motor which is adapted to receive the surgical device. The surgical device is driven through a continum of positions by the motor output shaft. A controller microprocessor (16) controls the operation of the system. The motor has sensors for generating electrical position signals (22) and the controller (16) is responsive to input signals for defining both a stop position and a reversal position for the surgical device. As a result, the controller (16) initiates operation of the surgical device at the so-called stop position and stops operation of the surgical device so that it comes to rest substantially at the stop position. In an oscillatory mode of operation, the controller (16) also forces reversals to occur solely at a reversal position dictated by the system, under the control of the user. In connection with an arthroscopic cutting device, the control enables the surgeon to control, for example, the opening of the aperture through which tissue and fluids are removed from the surgical site during the reversal and start/stop conditions.
