Medical microscope

Abstract

The invention relates to a medical microscope, which comprises a shell, an observation unit and an illumination unit, wherein the observation unit comprises a large objective lens arranged on an observation light path; the illumination unit comprises a first illumination unit and a second illumination unit, the first illumination unit comprises a first light source, the second illumination unit comprises a second light source, and the first illumination unit and the second illumination unit are arranged in the shell and located on the two sides of the large objective lens respectively; and the first lighting unit further comprises a first adjusting assembly used for adjusting the angle of light emitted by the first light source, and/or the second lighting unit further comprises a second adjusting assembly used for adjusting the angle of light emitted by the second light source. The medical microscope can provide sufficient illumination, and is low in cost, long in service life and low in power consumption; the built-in device is small, light and compact in structure; the internal mechanism is simple, the light path is not complicated, and the internal space is small; and the brightness adjustment is diversified, and the superposition is accurate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a medical microscope. Background technique [0002] In the medical field, both surgical microscopes and dental microscopes require better lighting conditions. The operating microscope is mainly suitable for the suturing of tiny blood vessels and nerves during the operation, and other fine operations or inspections that require the help of a microscope. The light intensity during the inspection directly affects the user's observation. The illumination optical system is an important part of the surgical microscope, providing a clear and bright operating field of view and observing details for the surgical process. [0003] The lighting methods of surgical microscopes are divided into internal lighting and external lighting. Some existing technologies use an external lighting device. The external lighting device usually guides the light into the microscope body through the light...

AI Technical Summary

Problems solved by technology

Although this structure takes advantage of the flexible bending of the guide beam, it is easy to arrange inside the microscope body, which makes it convenient to set up according to the needs of different operations for illumination methods, reduces the number of optical mirror groups on the illumination light path, and avoids complicated The lighting structure does not increase the volume of the microscope body, but the light emitted by the first lighting component and the second lighting component cannot be adjusted, so it cannot ensure that the light emitted by the first lighting component and the second lighting component can overlap to achieve the clearest lighting effects

[0006] In addition, when better lighting conditions are needed during surgery, and the brightness adjustment of the light reaches the limit, it is necessary to increase the LED lighting source, but at the same time it will bring many problems such as large size, space occupation, complex optical path, internal complex structure etc.
