Embodiment 1

[0029] as shown in the picture 1 、 2 an operating microscope 3D Imaging device, including housing 1 ,case 1 There is a mirror body connection part connected with the main mirror body 10 , the lens barrel connecting part connected with the binocular tube 11 。

[0030] in the shell 1 Built-in beam splitter 2 , variable aperture 3 , left and right steering mirror group 4 , left and right imaging mirror groups 5 and left and right photosensitive elements 6 . Where: Iris diaphragm 3 with adjustment operator 30 , adjust the operating part 30 exposed shell 1 Outside; left and right imaging mirror groups 5 Can use such as flat reflector; left and right photosensitive elements 6 can be CCD or CMOS 。

[0031] It works as follows:

[0032] Through the parallel double beams in the two symmetrical apertures of the main mirror body, through the beam splitter group 2 Divided into two paths, one path of double beams pass...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, the difference is that: 3 Shown: the left and right imaging mirrors 5 group including first left and right imaging lenses 50 , the second left and right imaging lenses 51 . Specifically:

[0035] in the shell 1 There is a horizontal beam splitter group inside 20 , beam splitter group 2 , variable aperture 3 , the first left and right imaging lenses 50 , left and right steering mirror group 4 , the second left and right imaging mirror groups 51 and left and right photosensitive elements 6 。

[0036] It works as follows:

[0037] Through the parallel double beams in the two symmetrical apertures of the main mirror body, through the transverse beam splitter group 20 After passing through the beam splitter group 2 Divided into two paths, one path of double beams passes through the binocular tube for the surgeon to observe; the other path of double beams passes through the...

Embodiment 3

[0040] This embodiment is basically the same as Embodiment 1, the difference is that: 4 Shown: the left and right imaging mirrors 5 group including first left and right imaging lenses 50 , the second left and right imaging lenses 51 ;Second left and right imaging lenses 51 , left and right photosensitive elements 6 secondary steering mirror 7 . Specifically:

[0041] in the shell 1 Built-in beam splitter 2 , variable aperture 3 , the first left and right imaging lenses 50 , left and right steering mirror group 4 , the second left and right imaging mirror groups 51 , secondary steering mirror 7 and left and right photosensitive elements 6 . Among them: left and right steering mirror group 4 Right Angle Prism 40 and rhombic prism 41 combination, as shown in the figure 5 shown; secondary steering mirror 7 The right-angle prism is used to turn again, shortening the height of the system, and turning the mirror image ref...

Abstract

The invention relates to a 3D imaging device for surgical microscopes, comprising a shell. The shell is provided with a lens body connecting part connected with a main lens body, and a lens cone connecting part connected with a binocular lens cone. A beam splitter group, a variable diaphragm, left and right imaging lens groups, and left and right photosensitive elements are arranged in the microscope body. After a double beam is split by the beam splitter group, one channel of double beam is imaged on the left and right photosensitive elements after passing through the variable diaphragm and the left and right imaging lens groups, and the other channel of double beam is observed directly through the binocular lens cone. The 3D imaging device of the invention is arranged separately, and can be directly connected with a surgical microscope as an accessory of the surgical microscope. The 3D imaging device has a simple structure, and is convenient to use. Users can observe through the binocular lens cone, without changing the using habit of the traditional surgical microscope.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to an operating microscope 3D imaging device 。 Background technique [0002] The most important function of human vision is to generate perception of depth through the difference in parallax between the left and right eyes. Traditional video and film and television systems only focus on the transmission and display of flat images. Although monocular flat images can also produce stereoscopic perception such as occlusion effects, depth of motion, relative size of objects and shadows. But the real stereoscopic effect can only be produced in stereoscopic video. [0003] When the human eye is watching a scene, the two eyes are separated by a certain distance, and they perceive the object from two different angles, and there are subtle differences between the left and right eye images. This difference can help the human brain to synthesize a complete three-dimensional...
