3D imaging device for surgical microscopes

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...
