膜をゆるめて歪をとる目的に行われるものである。When making a mark in the center of the eyeball during surgery such as myopia or astigmatism, it is usually difficult to see the center of the pupil, so a light spot should be created in the corneal part at the center of the pupil, and a doctor should make a mark with this as a mark. I have to. This is done by aligning the central holes (h) of the radial knurls (K) (see FIG. 6) so that the (C) (see FIG. 5) by the needle on the corneal surface becomes the center, and the radial knurls (K) are aligned. It is for pushing a scalpel into the eyeball and inserting a scalpel into it (see FIG. 5), and this operation is performed for the purpose of loosening the cornea and removing strain.

があり、また、発光ダイオードでは患者が見づらいとい
う欠点があった。In such cases, instead of applying a thin beam of light to the center of the eyeball to create a light spot, in the past, the light spot in front of the patient's eye was gazed at and the virtual image of the light spot reflected on the corneal surface was marked with a needle. I was trying to put in. That is, even if the patient is staring at the filament of the bulb of the illumination system of the surgical microscope, or by placing a light emitting diode near the objective lens of the surgical microscope and staring at it, the viewpoint is fixed and the virtual image of the light spot transmitted to the cornea. I was trying to use. However, the method of staring at the filament of the light bulb has a drawback that the patient is dazzling, and the light emitting diode has a drawback that the patient is hard to see.

In addition, the illumination light beam diaphragm means is arranged in the surgical microscope so that a part of the optical path can be used as a light spot of the fixation lamp when it is blocked.

The eyeballs of the patient can be observed through the lenses (L 1 ) and (L 1 ). Microscope bottom of the pair of observation objective lens (L 1), (L 1 ) from the optical axis equidistant proximate the objective lens to a position (L 1) (l 1) substantially parallel to the optical axis (l 2) An illumination lens (L 2 ) having is disposed, and illumination light is introduced from an external light source (not shown) through the light guide (10),
The illumination light flux (R) is emitted from the illumination lens (L 2 ) through the lens (L 3 ) and the optical path exchange mirror (11) to the eyeball of the patient. In the lens barrel (4) of one objective lens (L 1 ) of the pair of objective lenses, a shutter blade is provided with a pinhole (2) for narrowing the illumination luminous flux (R) when forming a fixation lamp. A diaphragm plate (3) which also serves as a rotary shaft is rotatably provided around the lens barrel (4), and an operating ring shaft (20) rotatably provided at the lower part of the main body of the microscope (A) is
By turning the actuating lever (15) planted on the outside of the diaphragm plate (3), the diaphragm plate (3) is moved through the pin (16) planted on the opposite side of the pinhole (2) of the diaphragm plate (3). The optical path of the illumination lens (L 2 ) is opened and closed by rotating the illumination window (18). That is, the illumination lens (L 2 )
When the operating lever (15) is turned clockwise (see FIG. 2 (a)) from the state in which the optical path is open [FIG. 2 (a), FIG. 3], the illumination window (18) is rotated. ) Is shielded, and the pinhole (2) formed in the diaphragm plate (3) substantially coincides with the optical axis (l 2 ) of the illumination lens (L 2 ) so that the illumination light flux (R) intercepts most of it. Then, a part of the illumination luminous flux passes through the pinhole (2) to form a fixation lamp, and the light spot can be observed from the patient side (see FIGS. 1, 2 (b) and 4). .. If the patient is allowed to gaze at the pinhole (2) in this state, a virtual image of the light spot of the pinhole (2) will be formed at approximately the center of the pupil (21) on the corneal surface of the patient's eyeball, and the doctor will It can be marked with a needle as a marker to prepare for the next surgery. Further, the operation opposite to the above, that is, the operation lever (15) is turned counterclockwise when viewed from above [see FIG. 2 (b)], and the optical path of the illumination lens (L 2 ) is opened [first]. 2 (a) and FIG. 3], the illumination light flux (R) emitted from the illumination window (18) irradiates the eyeball portion of the patient, and the operation can be performed.

することができる。That is, a diaphragm plate (3) having a pinhole (2) for forming a fixation lamp is arranged in the lower center of a pair of observation objective lenses (L 1 ) and (L 1 ) below the surgical microscope (A). The fixed right-angle pyrism (9) for guiding the illumination light is provided on the upper surface thereof. On the other hand, the lens barrel (4) of one observation objective lens (L 1 )
The shutter blades (13) are arranged around the axis in the same manner as the diaphragm plate (3) which also serves as the shutter blades in the first embodiment, and the shutter blades (13) are rotatably provided under the microscope (A). The ring (20) is rotated by the actuating lever (15) and the shutter blade (13) is rotated as shown in FIG. 8 (b) according to the state of FIG. 8 (a) to illuminate the illumination lens (L 2 ). Of the moving right-angle prism (8) so that the center of the light-receiving surface (5) of the right-angle prism (8) is located on the optical axis of the illumination lens (L 2 ) when the light path is blocked.
Is attached to the shutter blades (13). Receiving surface of the moving rectangular prism (8) (5), at the time of light shielding of the illumination lens (L 2) by the shutter blades (13), receiving light by the lower surface facing the shutter blades of the illumination lens (L 2) (13) A shield (7) is formed around the surface (5), and the reflecting surface of the moving right-angle prism (8) allows the light guide (10) to pass through the lens (L 3 ) and the optical path exchange mirror (1).
1), the illumination light guided through the illumination lens (L 2 ) reaches the fixed rectangular prism (9). Therefore, with the shutter blade (13) blocking the illumination light path, a part of the illumination light is fixed by the opposite surface of the fixed right-angle prism (9) at the lower center of the pair of objective lenses (L 1 ) and (L 1 ). The light spot as a fixation lamp is formed by being emitted through the pinhole (2) at the center of the diaphragm plate (3). When the patient is made to gaze at the pinhole (2) in this state, a virtual image of the light spot of the pinhole (2) is formed at the exact center of the pupil (21) on the corneal surface of the patient's eyeball. In the above,
The shutter blade (13) is retracted from the optical path of the illumination lens (L 2 ) by rotating the actuating lever (15) in the opposite direction of the fixation lamp formation, that is, clockwise in FIG. 8 (b) to a predetermined position. Then, the optical path of the illumination lens (L 2 ) is opened, and the illumination light flux is applied to the eyeball portion of the patient, so that the eyeball can be observed and surgery can be performed.

る。In the second embodiment, a pair of prisms including a moving right angle prism (8) and a fixed right angle prism (9) are used to fix a fixation lamp in the center between the pair of objective lenses (L 1 ) and (L 1 ). However, it is also possible to form a fixation lamp in the center between the objective lenses by guiding the front light flux from the illumination lens using a flexible light guide without using a prism. It is possible. Further, within the range not departing from the gist of the present invention, it is possible to make various modifications such as using an iris diaphragm instead of the illumination light beam diaphragm means in the above embodiment.
さらに、照明光束絞り手段の切替のための作動には上記

In addition, the fixation point can be formed by using a part of the illumination luminous flux by a simple switching operation so that the patient can easily see it, and the patient does not need another issuer for the fixation lamp. It is possible to provide a fixation lamp device for a surgical microscope which is easy to see and easy to operate, has a simple structure, and is advantageous in terms of cost.
