3D medical microscope

Abstract

The invention discloses a 3D medical microscope, which comprises a control unit for controlling the operation of the microscope, a shell with an internal chamber, and a first lens, a second lens, a reflecting unit and a driving unit which are arranged in the internal chamber. The first lens and the second lens are coaxially arranged; the reflecting unit is provided with a first reflecting surfaceand a second reflecting surface; the first reflecting surface is positioned between the first lens and the second lens, the first reflecting surface corresponds to the first lens and promotes an optical axis of the first lens to turn and project towards a vertical direction, and the second reflecting surface corresponds to the second lens and promotes an optical axis of the second lens to turn andproject towards the vertical direction. The driving unit drives the reflecting unit by a driving motor, so that the reflecting unit moves in the vertical direction.

Description

technical field [0001] The present invention relates to the field of microscope technology, in particular to a 3D microscope that can adjust the eye distance and eliminate visual vignetting in medicine, and can keep the entire picture clear and aligned during the process of switching magnification or lens shooting distance. medical microscope. Background technique [0002] In the past, microscopes used in medical operations were mainly provided with an objective lens group and at least two eyepiece lens groups at the front end of the body. The objective lens groups are connected, and the user can observe the images captured by the objective lens groups through each eyepiece lens group. [0003] However, because the lens in the objective lens group is a single and fixed structure, conventional microscopes can only provide stereoscopic images at the same depth, and cannot clearly present diseased tissues or blood vessels in some areas of the human body. As a result, doctors ...

Problems solved by technology

[0005] However, although the existing 3D stereoscopic surgical microscopes have used dual lenses to capture images, and can also switch the magnification and adjust the shooting angle, but the two lenses shoot directly downwards, so the magnification that can be switched is limited and easy. visual vignetting

More importantly, although the angle of shooting can be adjusted by swaying the lens, the oscillating lens also makes it difficult to focus, which in turn affects the alignment and image clarity (fuzzy picture). It is quite difficult and troublesome to use the positioner to correct the tilt angle of the lens

In addition, in order to control the two lenses, the existing 3D stereoscopic surgical microscope has two sets of adjustment units, which will not only occupy the operating space, but also cause the relative expansion of the entire microscope volume, which will easily block the doctor's operating line of sight, which is not conducive to the operation. conduct
