Abstract: There is provided an X-ray diffraction instrument including: a two-dimensional plate-like X-ray detector; an X-ray emitter integrated with the X-ray detector so as to penetrate the plate of the X-ray detector; a cylinder-like shield to define an orientation of the X-ray emitter and to prevent X-ray leakage, the X-ray detector being attached to one open end of the cylinder-like shield; and a standard powder attachment device to attach a standard powder for X-ray diffraction measurement to a surface of an object to be measured. The X-ray diffraction instrument can perform an X-ray diffraction measurement to an object larger than the X-ray detector thereof. The invented X-ray diffraction instrument is small in size, and can perform accurate X-ray diffraction measurement of stationary immovable objects without limitation on an orientation of the measurement surface. In addition, X-ray leakage is prevented for operator safety.

Abstract: An insertion device is used to deform a deformable intraocular lens to a reduced size and insert the deformed lens into an eye through an insertion tube. The insertion device includes a push rod for pushing and inserting the lens into the eye, and a posture control member disengagably engaged with a tip end portion of the push rod. The posture control member prevents deflection of the push rod from a center axis. The engagement between the posture control member and the push rod is broken when the push rod arrives at a predetermined position during a step of advancing the push rod.

Abstract: An intraocular-lens insertion device is adapted to deform a deformable intraocular lens into a smaller size and insert the intraocular lens into an eye via an insertion tube. An intraocular-lens guide is provided on the inner surface of the insertion tube. The guide may be a rail-shaped projection or a groove, which extends parallel to a direction along which the intraocular lens is pushed out. A stress release structure is provided on the insertion tube in order to release stress of the intraocular lens produced due to deformation thereof. Moreover, a frictional-resistance increasing structure is provided on the inner surface of the insertion tube to be located in the vicinity of the stress release structure. The frictional-resistance increasing structure increases frictional resistance between the inner surface of the insertion tube and the intraocular lens. The frictional-resistance increasing structure may be a roughened surface which completely or partially covers the inner surface of the insertion tube.

Abstract: In an insertion device for deforming a deformable intraocular lens to a smaller size and inserting the intraocular lens into an eye via an insertion tube, a slit is formed in an insertion end portion of the insertion tube, and cut surfaces of the slit and at least the inner wall surface of the insertion end portion are connected by curved surfaces.

Abstract: An insertion device for an intraocular lens includes a lens-holding section having a cavity for accommodating an intraocular lens, a deforming section for deforming the lens to a reduced size, an insertion tube through which the deformed lens is inserted into an eye, a pusher mechanism for pushing and inserting the lens into the eye, and a lens-moving mechanism for moving the lens from a standby position to an insertion position at which the pusher mechanism can push and insert the lens into the eye. A lubricant is injected into the interior of the insertion tube and/or the cavity of the lens-holding section for smooth insertion of the lens. The insertion device has an indicating mark for indicating quantity of the injected lubricant. Further, the insertion device includes an erroneous operation prevention member for preventing accidental operation of the lens-moving mechanism.

Abstract: An insertion device can deform a deformable intraocular lens into a smaller size and insert the intraocular lens into the eye. The insertion device includes a device body; an insertion tube attached to a front end of the device body and adapted to be inserted into the eye; and a push rod axially movable within the device body and the insertion tube and adapted to insert the intraocular lens into the eye when advanced. A drive member is rotatably provided at a rear end of the push rod. A motion conversion mechanism is disposed between the device body and the drive member and is adapted to axially move the drive member, upon rotation of the drive member, in order to axially move the push rod. A push member is provided at the rear end of the push rod and projects rearward from the drive member.

Abstract: An insertion system for an intraocular lens having a deformable optical portion and at least one loop-shaped support portion for supporting the optical portion within an eye includes a holding member for holding the intraocular lens at a standby position in a state in which no stress acts on the optical portion of the lens; a deforming member for deforming the lens to a reduced size; an insertion tube through which the deformed lens is inserted into the eye; a pusher mechanism having a push rod for pushing and inserting the lens into the eye; and a lens moving mechanism for moving the lens from the standby position to an insertion position at which the pusher mechanism can push and insert the lens into the eye. The tip end of the push rod is located between the optical portion and the support portion of the lens held at the standby position by the holding means, as viewed perpendicular to a plane along which the optical portion extends.

Abstract: An intraocular lens insertion device for inserting an intraocular lens into an eye has a data display section. The data display section displays data regarding a lens loaded onto the intraocular lens insertion device. The data display section is provided at a predetermined visible position on an outer surface of the intraocular lens insertion device so as to enable the data regarding the loaded lens to be checked from the outside of the intraocular lens insertion device.
