    摘要： The front end portion of a bending action member and manipulator is constituted of multi-slider linkage mechanism which starts the operation of a second articulation portion at its rear end side after the bending action of a first articulation portion on the front end side ends. A guide link portion 26 which covers a link member 23 to guide it through a sliding contact is sealed in a hollow portion to prevent leakage of air. In multi-slider linkage mechanism, two frames at a joint portion are formed in forward taper to set the magnitude of a moment required for starting the bending action of a second articulation portion larger than a moment required for the bending action of the first articulation portion. The manipulator is comprised of an actuator portion and a bending forceps portion and capable of engaging/disengaging each other. The actuator portion is provided with a joint arm 13 having a plate containing a fitting hole for connecting the motor with the link member 23. A connecting pin 21 is provided at an end on the engagement/disengagement side of the link member 23 inside the bending forceps portion and fitted to a fitting hole 13c in an elastic body 13a of the joint arm 13, so that the motor and the link member 23 are connectable/separable.

    摘要： This invention provides a bending mechanism that performs a ±90 degrees bending motion per degree of freedom (DOF) simply by directly sliding a pair of a multi-slider linkage mechanisms and enables multi-degree-of-freedom (MDOF) bending by combining two or more said bending mechanisms. To serve the purpose, the first frame 1, the second frame 3 and the third frame 5 are linearly arrayed and sequentially mounted to be rotatable about the first and the second rotating shafts 2 and 4, respectively. The first drive link 7, the second drive link 9 and the third drive link 12 are connected to the first frame 1 on the right side of the first rotary shaft 2. The first restraining link 15 and the second restraining link 17 are connected to the first frame 1 on the left side of the first rotary shaft 2. The first frame 1 turns right and left as the third drive link 12 is driven and slides.

    摘要： A system and method for automatic registration of medical images includes accessing image data of a subject and plurality of elongated fiducial markers arranged in an asymmetrical orientation and analyzing the image data to detect the elongated fiducial markers by applying a line filter to treat the elongated fiducial markers as lines within the image data. The system and method also includes matching the elongated fiducial markers within the image data to a model of the elongated fiducial markers, registering the image data with a coordinate system based on the matching, and generating a report indicating at least the registered image data.

    摘要： A capsule includes a main body with at least one tail connected to the main body. At least two coils are disposed on each tail such that the coils are responsive to a magnetic field interacting with the coils such that a force is exerted on the tail. The capsule is controlled through application of a varying magnetic field with a constant current in the coils and/or by providing varying a current in the coils that interact with a constant magnetic field. The capsule can be disposed in a cavity, and the magnetic field can be provided from outside the cavity to affect movement of the capsule. An MRI device can be configured to control and image the capsule.
