Description

The invention relates to the field of ophthalmic microsurgery.

A device for exfoliating tissues of the eye (patent N 2068251, from 10.27.1996) containing a handle connected to the transitional section with the working part, made in the form of a spherical conical head.

However, this device has a significant drawback: it does not ensure the absence of operational complications. The practice of ophthalmic microsurgical operations involves the use of a device for exfoliating the tissues of the eye, removing them with the subsequent introduction of a device for cutting tissues. Often there is a mismatch of the cutting plane with the plane of delamination, which leads to operational complications.

The technical result is the development of a tool that combines the functions of a device for cutting, delamination and a spatula to reduce operational complications.

The technical result is achieved by the fact that in an ophthalmic microsurgical instrument containing a handle and a working part, the working part is made in the form of a rectangular plate with a rounded front end surface, the rectangular plate is combined with the plate in the form of a curved isosceles trapezoid, the opposite side of the base facing the opposite side the handle, while the sides of the curved trapezoid are sharpened; the end rear part of the curved trapezoidal plate is rounded, and the rectangular and curved trapezoidal plate lie in the same plane.

The combination of distinguishing features of the invention proposed by the authors is necessary and sufficient for the unique achievement of the claimed technical result.

The claimed tool is illustrated by drawings: Fig.1-5.

Figure 4 - Section bb.

Figure 5 - Section CC.

The tool is made as follows. A tool for conducting ophthalmic microsurgical operations contains a handle and a working part. The working part is made in the form of a rectangular plate 1 (Fig. 1) with a rounded front end surface 2. The rectangular plate 1 is combined with the plate 3 in the form of an isosceles trapezoid, facing the lower side of the base in the direction opposite to the handle. The sides 4 of the trapezoid are sharpened (figure 4). The rear end 5 is rounded off. Moreover, the rectangular and curved trapezoidal plates lie in the same plane 6 (figure 2). The execution of the sides in the form of a curved isosceles trapezoid provides a decrease in the contact area of the cutting edge with the tissues of the eye, which leads to a decrease in trauma during surgery.

The proposed tool allows you to combine the functions of the cutting device, delamination and spatula and to reduce operational complications.

The tool is used as follows.

When carrying out an anti-glaucomatous operation after opening the scleral membrane, the instrument is inserted and the tissue is stratified using the rounded front end surface 2 of the instrument. Next, without removing the tool from the operating area, advance it and make a cut using the cutting edge 4 of the tool. Thoroughly clean the operation area using the rounded front end surface 2 of the tool. After performing the manipulations, the tool is removed back with minimal friction.

Using the tool allows you to achieve the claimed technical result - to combine the functions of the device for cutting, delamination and spatula to simultaneously reduce operational complications.
