    Publication number: 20180103979
    Abstract: An apparatus (51) includes a needle placement manipulator (1) and an attachment (52) for the manipulator. The manipulator includes a needle holder and a rotary mechanism. The rotary mechanism (3, 4) has a remote center of motion (RCM: 11) and is configured to position a needle holder (5) such that the axis of the needle holder traces a conical region of coverage (108), the conical region of coverage having the apex thereof at the RCM and the base thereof in a direction towards a subject of needle placement (14). The attachment supports the guide mechanism and is configured to be mounted onto the subject of needle placement. The attachment includes a guide portion (183c) configured to change an inclination of the rotary mechanism with respect to the subject of needle placement such that the axis of the needle holder intersects an insertion target (14) located outside of the conical region of coverage.

  • Robotic endoscope probe having orientation reference markers
    Patent number: 11786106
    Abstract: An endoscope imaging system comprises a robotic controlled steerable catheter and an imaging device removably arranged in a tool channel of the catheter. One or more sensors or markers are configured to map a positional relation of the catheter with respect to an orientation of the imaging device. A controller drives the steerable catheter to manipulate the distal end thereof, while the imaging device acquires an image of a subject or sample. While the imaging device acquires the image, a processor calculates a change in positional relation of the catheter with respect to the orientation of the imaging device based on information provided by the one or more sensors or markers. An output unit provides an indication for remapping the orientation of the steerable catheter with respect to the orientation of the imaging device.

    Abstract: 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.

    Patent number: 11051892
    Abstract: An apparatus including a tendon-driven device such as an endoscope comprising a bendable body, a tendon attached to and extending a length of said body, and an actuator that will actuate said tendon based on a control signal from a controller. The controller is configured to send said control signal to said actuator and comprises a forward-kinematic-mapping unit that estimates an angular displacement, wherein the kinematic-mapping unit is configured for: providing a tension value of the tendon to obtain a desired angular displacement wherein the tension has a nonlinear relationship with the desired angular displacement based on information of friction where the tension is greater that would be calculated without including the effect of friction. The friction coefficient may be determined as it changes over time.

  • Bending Action Member, Multi-Slider Linkage Mechanism, Actuator And Manipulator
    Publication number: 20070219581
    Abstract: 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.
