Shading frame for microscopic observation of pathological section

Abstract

The invention discloses a shading frame for microscopic observation of a pathological section and relates to the field of microscope assistive devices. The shading frame comprises eyepiece fixing sleeves, a sliding connection assembly and shading sleeve assemblies. The number of the eyepiece fixing sleeves is two, and the eyepiece fixing sleeves are detachably connected with an eyepiece lens. Thenumber of the shading sleeve assemblies is two, bottom ends of the two shading sleeve assemblies are fixedly connected with top ends of the eyepiece fixing sleeves respectively, the other ends are overturned outwards and fixedly connected with the sliding connection assembly, cross sections of the overturned shading sleeve assemblies are arranged to be in an inverted trapezoid shape, and the sliding connection assembly sleeves the two eyepiece fixing sleeves in a sliding mode. The shading frame can be connected with the two eyepieces, the sliding connection assembly is moved up and down to drive a folding shading sleeve to turn over up and down, the vertical distance between the folding shading sleeve and the lens can be adjusted, a contact area between a top end surface of the folding shading sleeve and an eye socket can be adjusted too, and the shading frame is suitable for different crowds.

Description

technical field [0001] The embodiments of the present invention relate to the field of microscope aids, and in particular to a light-shielding frame for observing pathological slices under a microscope. Background technique [0002] When using a microscope to observe the rapid pathological slices from the operating room, the glasses of the general pathologist are close to the eyepiece lens of the microscope. When observing objects with a microscope, the eyepiece, lens barrel, objective lens, and light hole of the microscope must be on the same straight line .The light reflected by the mirror can reach the eyes through the aperture, objective lens, lens barrel and eyepiece in turn. The aperture under the glass slide can be adjusted by adjusting the size of the aperture. However, when the surrounding environment is strong The light is easy to reflect on the eyepiece glass lens, which affects the observation effect of pathologists and is prone to visual fatigue. [0003] In th...

Problems solved by technology

[0004] However, the technical solutions adopted in these patents all use the shading frame fixed on a separate eyepiece, and the existing microscope eyepieces are generally arranged side by side as two, and the distance between the two eyepieces can also be adjusted to adapt to different microscope eyepieces. It is used by people with eye distance; therefore, continuing to use the technical solutions in the above patent documents will cause inconvenient operations such as adjustment and fixation of the shading frame
