Patent number: 9108783Abstract: An extraction bag is disclosed that has a body that can be squeezed using hanging threads. A portion of a sheet body is folded back, and point seals are provided in the folded-back area. Two hanging threads are attached with the point seals as supporting points. Then, when the hanging threads are pulled in opposite directions, the direction of the one hanging thread is guided during pulling by the point seals and the end of an edge seal as supporting points, and the direction of the other hanging thread of a tag-attached hanging thread is guided during pulling by the point seals and the end of an edge seal as supporting points. By this means, the point seals are first pulled towards one another and then the base seals of the threads are also pulled towards one another, thereby squeezing the bag body from three dimensional directions.Type: GrantFiled: June 17, 2010Date of Patent: August 18, 2015Assignee: FUSO INDUSTRY CO., LTDInventor: Yasuhiko Suzuki

Patent number: 9072601Abstract: 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.Type: GrantFiled: October 22, 2009Date of Patent: July 7, 2015Assignee: KOWA COMPANY, LTD.Inventors: Masayoshi Tanaka, Kazuharu Niwa, Yasuhiko Suzuki
