Microsurgery auxiliary device

Abstract

A microsurgery auxiliary device provided in the present invention, comprises a lens body () and a naked eye 3D display (), the lens body () being 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 located 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, and the spacing between the positive lens group () and the negative lens group () is adjustable; and the naked eye 3D display () is connected to the photosensitive element (), the distance between the naked eye 3D display () and an observer () is 400-1200 mm, and the viewing angle range of the naked eye 3D display () is not less than 120 degrees. The observer can directly perform surgical operations by observing the naked eye 3D display (), the overall structure of the device is simple, and the system delay is small.
