  • Patent number: 9072601
    Abstract: An intraocular lens insertion device having a novel configuration, capable of more accurately arranging front and back surfaces of an intraocular lens in a proper direction. The intraocular lens insertion device is adapted in such a manner that the intraocular lens is set on a stage in a state placed flat with a pair of haptics extended facing front and back sides in a movement direction by a plunger. Also, an interfering acting part is provided to an insertion tube part, and the interfering acting part interferes with the haptic, which is extended facing the front side in the movement direction of the intraocular lens moved by the plunger, to apply on the haptic an external force toward the back side in the movement direction. Thus, the interfering acting part curves and deforms the haptic to a side approaching an optical portion.

  • Patent number: 8393364
    Abstract: In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel.

  • Publication number: 20120253356
    Abstract: An intraocular lens insertion device having a novel configuration in such a manner that, with the displacement of a haptic toward the convex side of an optical portion, which can be deformed in a curved shape, restricted by an engaging part provided to the tip part of a plunger, the haptic is deformed in a curved shape in the direction in which the haptic approaches the optical portion. The configuration allows, when the intraocular lens is pushed out by the plunger, the haptic to enter a gap formed on the concave side of the optical portion which has been deformed in a curved shape.

  • Patent number: 8152817
    Abstract: An intraocular lens insertion tool with a tool body for accommodating an intraocular lens and adapted to insert into an eye the intraocular lens through displacement of the lens in an axial forward direction by a plunging member, and to push out the lens through an insertion tube section disposed at an axial distal end of the tool body. A base plate of a resting portion that houses the lens is provided with side plates that respectively project from two widthwise edges of the base plate to both sides in a thickness direction of the base plate thereby imparting to the resting portion a generally “H” shaped cross section. The tool body inclusive of the resting portion and the insertion tube section is integrally formed from light-transmissive synthetic resin material whereby the lens housed within the resting portion is viewable from an outside through the base plate.

  • Patent number: 8021423
    Abstract: An insertion tool of an intraocular lens permits the lens to be deformed while rotation of the lens in an insertion tube is effectively prevented. Upper and lower flat planes are formed to spread flatly over a length of a through hole in the insertion tube and the upper and lower flat planes are connected smoothly with right and left wall faces over the length of the through hole. The right and left wall faces have longitudinal linear portions extending substantially in parallel in a vertical direction on a proximal end opening side. With its radius of curvature decreasing gradually in a covered shape which becomes inwardly concave as it approaches a distal end opening the upper flat plane gradually approaches the lower flat plane, and a tapered portion having a reduced cross-sectional area is formed, thus obtaining the distal end opening of substantially oval shape.
