  • Publication number: 20210353373
    Abstract: A medical device includes a shaft, a beam, a hard stop structure, and a link. A proximal end portion of the beam is coupled to the distal end portion of the shaft and a distal end portion of the beam is coupled to the link. A strain sensor is on the beam. A hard stop structure includes a proximal end portion, a distal end portion, and first opposing stop surfaces. The proximal end portion of the hard stop structure is coupled to a distal end portion of the shaft, and the distal end portion of the hard stop structure is coupled to the link. The first opposing stop surfaces are positioned to limit a lateral range of motion of the distal end of the beam with reference to the proximal end of the beam in a first direction by the first stop surfaces contacting one another.

  • Publication number: 20200397522
    Abstract: A low-friction medical device includes a first link, a second link, and a tension member. The first link is coupled to an instrument shaft and a first guide path is defined in the first link. The second link is rotatable relative to the first link through an angular range. A distal end portion of the second link is rotatably coupled to a tool member. A curved guide path is defined within the second link between the tool member and the first guide path. A curved guide surface of the second link defines a portion of the second guide path. A first portion of the tension member is parallel to a centerline of the first guide path, and a second portion is coupled to the tool member. A third portion of the tension member between the first and second portions is in contact with the curved guide surface throughout a portion of the angular range.
