Abstract

The invention is intended for ophthalmology. The purpose of the invention is to provide the possibility of measuring in three coordinate axes and to increase the convenience of the study. The device comprises a housing, a measuring ruler 2 rigidly attached thereto, carrying a carriage 3 that is movable relative to it. The latter is mounted on a ruler 2 by means of rolling bearings and is provided with an elastic drive roller 4 with a handle 5. In a carriage 3 the measuring ruler 6 is movably mounted on rolling bearings. In the holder 8, an optical head 9 is installed with its own movement mechanism. The housing of the device is placed on the telescopic housing 11, which allows adjustment in height and angular position. The latch angular position of the tripod 11 has a rusk 13 and a ring 14 with a groove. 2 Il.

The invention relates to medical technology, in particular to ophthalmic devices for determining the pathological mixing of an eye block, and can be used in medical institutions of the eye as well as the maxillofacial profile.

The purpose of the invention is to provide the possibility of measuring in three coordinate axes and to increase the convenience of the study.

FIG. 1 shows the proposed device, top view; in fig. 2 is a view A of FIG. I.

The device comprises a housing 1, a measuring ruler 2 rigidly fixed thereto, a dry carriage 3 moving relative to it, the carriage 3 is mounted on a ruler 2 with the help of rolling bearings and equipped with an elastic drive roller 4 with a handle 5. In the carriage 3 perpendicular to the ruler 2 and above it is movably mounted on rolling bearings a second measuring ruler 6, also driven by an elastic roller with a handle 7. At the end of the ruler 6 in the holder 8 there is an optical head 9 with its own mixing mechanism with the aid of the setting knob 10 in direction perpendicular to both measuring lines 2 and 6.

The device body 1 is mounted on a telescopic stand 11, which by its base 12 can be fixed on an operating table or on another installation. Telescopic stand 11 allows adjustment in height and angular position. It is also equipped with a corner retainer.

a position in which the cracker 13 and the ring 14 with a groove are inserted.

The device works as follows.

The patient is placed on the operating table and fix his head in the head restraint (not shown). The stand 11 is fixed by the base 12 and is adjusted in height and angular position so that the ruler 2 is parallel to the plane of symmetry of the skull. After this, the angular position of the fixture is fixed.

The optical head 9 is mixed with the help of the handle 10 until the image is sharpened at a characteristic point on each eye and the readings are taken on the appropriate scale.
