  • Publication number: 20200261104
    Abstract: A medical gripping tool includes: an elongated insertion section; a gripping section; an operating unit; and a wire that transmits, to the gripping section, a driving force input to the operating unit. The gripping section includes a pair of gripping pieces supported so as to be relatively swivelable. The pair of gripping pieces include a pair of first gripping sections, and a pair of second gripping sections that are disposed at positions farther away from a swiveling axis than the pair of first gripping sections are. In a state in which the pair of gripping pieces are closed by the driving force transmitted by the wire, opposed surfaces of the pair of first gripping sections are disposed with a first distance therebetween, and opposed surfaces of the pair of second gripping sections are disposed with a second distance, which is longer than the first distance, therebetween.

  • Publication number: 20200114527
    Abstract: A joint structure of a manipulator includes: swiveling members that are coupled so as to be able to swivel via a rolling contact; shafts that constitute bending joints between the swiveling members and that are parallel to each other; pulleys that are rotatably supported about the shafts; and a connector attached to the shafts so as to be able to swivel about longitudinal axes of the shafts. The connector includes supports that are disposed on axial ends of the shafts so as to sandwich the pulleys therebetween in a direction of the longitudinal axis, and a beam that extends in between the supports to couple the supports to each other.

  • Patent number: 10343291
    Abstract: A gripping mechanism according to the present invention is provided with: two gripping pieces pivoted about a pivoting axis; a gripper main body that supports the gripping pieces at a distal-end portion; a pulley that is supported about a rotation axis that is parallel to the pivoting axis; an opening wire that is wound around the pulley that has one end secured to the gripping pieces or the gripper main body, and that causes tensile forces that cause the rotation axis to be moved in one direction pulley, wherein the pulley is disposed so that a resultant force of the tensile forces in the opening wire that acts on the rotation axis becomes greater than the pulling force, and so that a moment that causes the gripping pieces to be pivoted in the directions in which the gripping pieces are opened relative to each other is generated.
