Description

Multi-position stereoscopic vision multi-wavelength video ophthalmic surgery microscope

Technical Field

The utility model relates to the field of microscopes, in particular to a multi-position stereoscopic vision multi-wavelength video ophthalmic surgery microscope.

Background

The operation microscope is a common medical operation microscope device, and the ophthalmic operation microscope is also widely used for ophthalmic operation. In the existing operation microscope, the microscopic observation part mostly adopts an optical system consisting of optical lenses such as a main objective lens, a variable power objective lens pair, a light splitting and image rotating prism, an ocular lens and the like; the illumination part generally takes a tungsten filament bulb, a halogen bulb, an LED lamp or a xenon lamp as a light source, and forms an illumination system through a light guide beam and other optical elements, and the illumination system comprises coaxial illumination, oblique illumination and slit illumination.

The content of the inspection and guidance principle of the registration technology of the operation microscope released by the State food and drug administration is quoted: the structure of the existing operation microscope is shown in fig. 17, the operation visual field plane 2 ' of the existing operation microscope 1 ' is divided into two paths by the zoom objective pair 12 ' after passing through the main objective 11 ', passes through the beam splitter 13 ', the binocular tube 14 ' and the ocular 15 ', and then exits the pupil for the user to view in binocular; the operation microscope can be provided with a hand assistant mirror, an image acquisition and processing system and other related accessories through the light splitter. The hand-assisted glasses can be provided with a tube for single-eye or double-eye observation and used for assisting the operation; the existing operating microscope lighting system generally comprises a tungsten filament bulb, a halogen bulb, an LED lamp and a xenon lamp as light sources, and a lighting system consisting of a light guide beam and other optical elements and has the functions of coaxial lighting, oblique lighting and slit lighting.

However, the existing surgical microscope has the following disadvantages:

1. the distance from the operation visual field plane to the binocular exit pupils of the user is fixed, the user can adapt to the distance no matter the height of the user and the length of the hands, and particularly, the user with short hands can difficultly adapt to the posture of the distance to carry out fine microsurgery.

2. The numerical aperture is determined by the focal length of the objective lens and the effective clear aperture, and the illumination needs to be improved for clearer vision in the operation; in particular, ophthalmic surgical microscopes are prone to damage to the retina of the eye from light radiation if the illumination is increased indefinitely for clarity.

3. The capture and focusing of the operation vision field target are both observed in a binocular stereoscopic eyepiece for adjustment, the attention of a doctor is dispersed, and a patient needs to keep a posture without moving.

4. The direction of the illumination light source is single, and the medium such as cornea, crystal and the like is mostly curved and highly reflective, so that reflective interference often occurs in the operation process.

5. The vitreous body cutting operation is a main function, the vitreous body cutting is an inverted image, in order to solve the inverted image problem, a vitreous body cutting inverted image mirror needs to be additionally arranged at the front end of a large objective lens to enable the large objective lens to be inverted into an upright image, the distance from an operation visual field plane to the binocular exit pupil of a user is longer and longer, and the short user with short hands is more difficult to master.

6. The user can directly observe the operation visual field position through the optical system by naked eyes, and the existing operation microscope is mainly white light due to the visual obstacles of monochromatic light, infrared light, fluorescence contrast exciting light and the like.

7. The eye lens exit pupil can cause eye fatigue of a user, and the bigger the magnification of the eye lens is, the more fatigue is easy to occur.

8. The assistant mirror connected out through the optical splitter is only suitable for the side view of the assistant and is not suitable for help.

9. Related accessories of image acquisition are installed through a light splitter, however, most of the related accessories are collected by separating a single side from one path in three-dimensional two-path optics, the effect of the acquired image is similar to that of opening one eye and closing one eye, and the acquired image is not satisfactory as a medical image for surgical video recording and remote teaching communication.
