Description

Device FOR marking the cornea during ophthalmic surgery

The utility model relates to medicine, namely to ophthalmology, and can be used in ophthalmic surgery.

A device is known for marking the cornea of an eye during a surgical operation, comprising a marker, which is made in the form of a holder, on which there are marking plates having an arcuate shape that repeats the shape of the cornea, and a reticle (AS No. 1021454, A61F, 1983).

A disadvantage of the known device is the low accuracy of the marking due to the need to use tweezers or hands during installation, as well as due to the lack of graduated divisions.

The purpose of the utility model is to increase the accuracy of the marking of the eye and the possibility of simplifying the work of the surgeon.

This goal is achieved by the fact that in the device for marking the cornea of an eye during an ophthalmic surgery containing a marker made in the form of a holder, on which there are marking plates having an arcuate shape that follows the shape of the cornea, and the sight, additionally, the holder is made flat, on both sides with with pointed ends, on the inside of which there are marking plates with a pointed edge, in addition, a handle is attached to the holder at an angle of 135 ° to the plane, and the sight is made in the form of a flat a ring with graded graduations and handle as attached at an angle of 135 ° to the plane of the ring.

Figure 1 shows a device for marking the cornea during ophthalmic surgery (general view); figure 2 - scribe (general view); fig.Z - VIEW A in figure 2; FIG. 4 is a view B of FIG. 3; FIG. 5 is a view B in FIG. 3; Fig.6 VIEW G in Fig.Z; Fig.7 - DD in Fig.6; Fig.8 is a sight (General view); Fig.9 - E in Fig.8; figure 10 - VIEW F in Fig.8.

MPKA61R9 00

A device for marking the eye during ophthalmic surgery contains a marker 1 and a sight 2 (figL). Marker 1 is made in the form of a handle

3, to which a holder 4 is attached at an angle of 135 to the plane (FIGS. 2, 3). The holder 4 is made flat, on both sides with pointed ends (Fig.Z,

4,5,6). On the inner side of the holder 4 there are marking plates 5 with a pointed edge. Viz1f 2 is made in the form of a flat ring 7 with graduated divisions and a handle 8, also attached at an angle of 135 ° to the plane of the ring.

When the surgeon uses an optical system, for example, a microscope, holding two handles 3 and 8 with his hands, the surgeon combines the marker 1 with the sight 2 so that the arrows of the plate 4 are inside the sight 2. Turning the handle 3, the surgeon selects graduated marks on the ring 7 the required angle (size), combining the center of the sight 2 with the optical axis of the eye. Then, on 2-Cc, presses the pointed surface 5 of the marking plate 4 to the cornea of the eye. After removing the marking device, visible marks remain on the cornea, along which the surgeon makes linear incisions.

Due to the high accuracy of the marking, the displacement of the optical axis of the eye after the operation is completely prevented, the operation time is significantly reduced and the work of the surgeon is simplified.
