Microsurgery auxiliary device

A microsurgery auxiliary device, comprising a lens body and a naked eye 3D display, wherein the lens body is internally provided with an imaging unit, the imaging unit comprises a large objective lens group, a zoom lens group, a first tube objective lens and a photosensitive element, the large objective lens group, the zoom lens group, the first tube objective lens and the photosensitive element are sequentially positioned in the same observation optical path, the large objective lens group comprises at least one positive lens group and at least one negative lens group, the positive lens group and the negative lens group are arranged in the same optical axis, a distance between the positive lens group and the negative lens group is adjustable, the naked eye 3D display is directly connected to the photosensitive element, enabling low system delay between the naked eye 3D display and the photosensitive element and without complex data processing on image captured by the photosensitive element,

• wherein the microsurgery auxiliary device further comprises an acquisition device, a processing device and a driving device, the acquisition device is to acquire position information of human eyes of an observer, and the processing device is to control the driving device to rotate with the eyes of the observer to ensure that a viewing angle of the observer is in a range of not less than 120 degrees with respect to the naked eye 3D display while a distance between the naked eye 3D display and the observer is in a range of 400-1200 mm.
