  • Patent number: 10993764
    Abstract: A surgical instrument with insulating grips is described. The grips can include internal metal frames that are arranged to limit electrical conductivity within the grips and to other components that attach to a grip, such as a ratchet. The internal metal frames can be constructed of multiple internal portions, spatially separated from one another to interrupt electrical conductivity between the internal portions, but coated with an insulating overmold to provide mechanical coupling between the portions. An internal metal frame can also include a notch, cut-out, or other region partially surrounded by the structure of the internal metal frame, which can be coated with an insulating overmold to define a region of the grip that does not have an internal metal frame therein but which can include an attachment point for mechanically coupling other components while limiting electrical coupling between the metal frame and the other components.

  • Patent number: 10980559
    Abstract: In a treatment instrument, one of a pair of jaws is supported by a supporter while being pivot able around the supporter with respect to the supporter. A drive member moves along a longitudinal axis so that the pair of the jaws are closed with respect to each other, thereby applying an axial force onto an elongated member from the drive member by way of the one of the jaws and the supporter in a direction along the longitudinal axis. A contact surface of the elongated member abuts on a housing when the elongated member moves with respect to the housing under the axial force, thereby suppressing rotation of the elongated member around the longitudinal axis with respect to the housing.

  • Patent number: 9888910
    Abstract: An eyelid speculum for retracting a pair of eyelids, comprises: a first arm having a first blade portion contoured to generally conform to an eyeball globe and one of the pair of eyelids; a second arm having a second blade portion contoured to generally conform to the eyeball globe an the other of the pair of eyelids; and a mechanism carrying the first arm and the second arm. The mechanism is operable to hold the first arm and the second arm parallel to and in proximity to each other so that the first blade portion and the second blade portion may be inserted between said eyelids to engage said eyelids. The mechanism is further operable to move the first arm and the second arm apart from each other while maintaining the first arm and the second arm in parallel such that the first blade portion and the second blade portion retract said pair of eyelids. The mechanism advantageously moves away from the surgical field of the eye when retracting the eyelids.
