Abstract: A needle holder for holding a curved needle to which a suture thread is connected. The needle holder includes a flexible tube; and a grasper provided at a distal end of the flexible tube. The grasper includes a first jaw having a groove, and a protrusion at a distal end portion of the first jaw; and a second jaw movably connected to the first jaw. The grasper can hold the curved needle between the second jaw and the protrusion of the first jaw, and can hold a part of the suture thread between a surface of the groove and the second jaw such that another part of the suture thread passes through a gap formed between another surface of the groove and the second jaw. The protrusion has a hook surface for hooking the suture thread extending outside the groove.

Abstract: The first fixing member and the second fixing member are arranged such that the first clamping surface and the second clamping surface face each other in an axis line direction of the insertion portion. When the manipulation portion is manipulated and the insertion portion and manipulation member is rotated relatively, the first clamping surface and the second clamping surface are configured to approach by screw-fitting with the second fixing member and the first fixing member. When a predetermined manipulation is performed to the manipulation portion, a coupling between the manipulation member and the other is configured to be released.

Abstract: A reflection-type liquid crystal display device comprises a liquid crystal cell, a polarizing film, a birefringent film, a scattering layer, and a light reflection means, in which a diffuse reflection factor “R” of the scattering layer is designed to be 7% or greater, but 110% or less when an incident angle of light is in the range of 25° or greater and 45° or smaller. Here the diffuse reflection factor “R” is defined by the formula of R=R1/R2×100 (where R1 is a reflection factor irradiated at an incident angle of 0°, and R2 is a reflection factor irradiated at an incident angle of 25°). This structure is able to provide a reflection-type LCD which is bright in White display, capable of producing a high contrast, and reducing blur of an image.
