Abstract

The invention relates to a surgical microscope, which comprises a bracket component and a microscope main body, wherein the bracket component comprises a stand column, a first supporting arm, a second supporting arm, a third supporting arm and a balance arm which are sequentially and rotatably connected, when the balance arm is locked with the third supporting arm, the microscope main body is pushed to drive the first supporting arm to rotate with the stand column, the second supporting arm to rotate with the first supporting arm, the third supporting arm to rotate with the second supporting arm, and when the balance arm is unlocked with the third supporting arm, the microscope main body is pushed to drive the third supporting arm to rotate with the second supporting arm and the balance arm to rotate with the third supporting arm. The invention can easily complete large-range adjustment among the upright post, the first support arm and the second support arm which are far away from the lens, and small-range adjustment among the second support arm, the third support arm and the balance arm which are close to the lens, thereby avoiding the situation of difficult rotation caused by top death among the support arms, greatly controlling the adjustment range, reducing the adjustment difficulty, improving the operation comfort of doctors and improving the operation efficiency.
