The basic structure of the existing mechanical synoptic machine is as follows: a metal box is arranged on the base, and the rotating parts and circuits of the machine are stored in the box. Two metal arms are arranged on the base, and the metal arms are connected to the lens barrel. Each lens barrel Including eyepieces, reflectors and picture clips, pictures used for inspection or treatment are inserted into the picture clips, there is a dial on the base of the metal arm, and there are two rows of scales engraved on it, one for the circumference and the other for the degree of the prism. Indicates the angle by which the lens barrel is rotated. The two lens barrels can be rotated 50 degrees inward and 40 degrees outward. The height of the picture and the rotation scale are attached on the lens barrel, which can be moved up and down and rotated. Its key components are two lens barrels. The lens barrels move in various directions centered on three axes: horizontal movement in two directions of adduction and abduction around the vertical axis; vertical movement in the up and down direction around the horizontal axis; vertical movement around the horizontal axis; Sagittal axis for rotational movement. The movement of the lens barrel in all directions is centered on the eyeball. A mirror is installed in the lens barrel, which is at an angle of 45 degrees to the line of sight, so that the two lens barrels can be bent 90 degrees to the left and right respectively, so that the patient feels that the object image comes from the front. The outer end of the lens barrel is equipped with an eyepiece, the inner end is inserted with a picture, and a spherical lens with +7D diopter is placed in the middle, so that the picture is placed on the focus of the spherical lens, so that the light can be paralleled. Infinity effect. The two arms of the synophore control the horizontal movement of the picture. The two arms can move independently, and can also be fixed with a lock to perform different directions of collection or abduction, and can also perform parallel movements. Through different knobs, the pictures can be moved vertically and rotated. The doctor can adjust the lens barrel to each diagnostic eye position for examination or treatment.

The principle of the mechanical synopic machine is to use two lens barrels to separate the visual field of the two eyes. The left eye looks at the left picture, and the right eye looks at the right picture. The cortex processes, analyzes and synthesizes. If you have binocular vision, you can combine the images from both eyes into one and feel it as one object. If you don't have binocular vision, you can use the scale on the synoptic machine panel to know the patient's strabismus, and perform binocular synchronism. Depending on the treatment.

The above-mentioned mechanical synopic machine has the following disadvantages: First, the doctor cannot see the content of the pictures examined or treated by the patient, so that he cannot understand and guide its operation, and the examination and treatment data cannot be automatically recorded and analyzed, and can only be recorded through the patient's dictation. , The doctor knows the result, so there is a large inspection error, and the treatment effect is also poor. Secondly, during inspection or treatment, the left and right pictures must be manually adjusted to a suitable position, and the manual control is imprecise and the operation is troublesome.
