Description

The invention relates to medicine and can be used to correct paralytic lagophthalmus.

For the correction of paralytic lagophthalmos, as a rule, implants are used, which, when placed in the upper eyelid, under the influence of gravity, contribute to its closure during blinking movements and with arbitrary closing of the eye.

The magnitude of lagophthalmos in all patients is different, respectively, and the mass of the implant is selected individually. To determine the mass of the implant, sufficient for the correction of lagophthalmos and not causing significant ptosis, test sets of measuring weights are used.

For example, a set of measuring weights of the company IOP Inc., www / iopinc.com. Is known, in which each of the weights has a vertically mounted plate on the outer surface, made in the form of a rectangular rib and designed to be held with standard tweezers.

Such a plate is difficult to fix with forceps with solid working surfaces, and a weight with a protruding plate can only be used as a means of measurement and cannot be used as a permanent implant and an external weighting weight for correcting lagophthalmos.

Another drawback of IOP Inc. measuring weights. It is that the additional protrusion of the front surface of the implant causes the displacement of the gravity vector several anteriorly and the uneven distribution of mass over the surface area. All this can lead to incorrect calculation of the mass of the implant, incomplete elimination of lagophthalmos or the development of ptosis of the upper eyelid.

Known weights that are first installed on the outer surface of the eyelid to determine the mass of a permanent implant or the mass of an external weight suitable for treating a particular patient, who is fixed on the eyelid, usually with a band-aid (US 5542437 A, 08/06/1996).

Since external weights, if possible, should be minimally visible to those around them without the means to hold them with any tool, makes their installation uncomfortable and makes it difficult to fix them on the eyelid.

The problem to which the invention is directed is the development of an external weight for correcting lagophthalmos and a holder specially designed for it, which allows overcoming the disadvantages of known designs.

The technical result of the invention is the ease of installation of the weight, the accuracy of its fixation on the eyelid of the patient, the greater accuracy of calculating the mass of a permanent implant, as well as the possibility of using a measuring weight to correct lagophthalmos.

The invention is expressed in the combination of essential features, in which a set for correction of lagophthalmus containing at least one measuring weight, in the form of a first elongated plate with a concave working surface for installation on the outer surface of the eyelid and at least one correction weight, in the form the second elongated plate with a concave working surface for installation on the outer surface of the eyelid, differs from the closest analogue in that it additionally contains at least one holder for measuring body weight in the form of two springy branches that are connected by non-working ends to each other and have protrusions from 1.5 to 6 mm long with cross sections in the form of rectangular trapezoidal tubes oriented towards each other with beveled sides at an angle of 35-55 ° to the plane of movement of the branch, while the first curved elongated plate has a working surface with a bending radius of 10 to 14 mm and is made with longitudinal grooves in the middle sections of the sides or with transverse grooves in the middle longitudinal axes, each of which has a length of 1.5 to 6 mm, the cross section is in the form of a rectangular trapezoid and is shifted to the convex non-working surface of the first plate, moreover, the beveled sides of the grooves are oriented towards each other and are located at an angle of 35-55 ° to the plane moving the jaw of the holder of the measuring weight, and the second curved elongated plate has a bending radius of the working surface of 10 to 14 mm, a weight equal to the weight of the measuring weight, and a convex non-working surface made to fix the adhesive tape, for example, for ksatsii patch.

The lagophthalmos correction kit contains at least one measuring weight, in the form of a first elongated plate 1 with a concave working surface 2 for installation on the outer surface of the eyelid, at least one correction weight, in the form of a second elongated plate 3 with a concave working surface 4 for installation on the outer surface of the eyelid and at least one holder of the measuring weight in the form of two spring jaws 5 and 6. The jaws 5 and 6 of the holder are connected by non-working ends 7 and 8 and have projections 11 and 12 at the working ends 9 and 10 from 1.5 to 6 mm long with cross sections in the form of rectangular trapezoid. The protrusions 11 and 12 are oriented towards each other with beveled sides located at an angle of 35-55 ° to the plane of movement of branches 5 and 6.

The first elongated plate 1 is made with longitudinal grooves 13 and 14 in the middle sections of the sides or with transverse grooves in the middle longitudinal axis (not shown in the drawing), each of which has a length of 1.5 to 6 mm, a cross section in the shape of a rectangular trapezoid and the offset along the thickness of the plate 1 to its convex non-working surface 15. The chamfered sides of the grooves 13 and 14 are oriented towards each other and are located at an angle of 35-55 ° to the plane of movement of branches 5 and 6 of the measuring weight holder. The correction weight has a weight equal to the weight of the measuring weight, a concave working surface 4 and a convex non-working surface 16, made to fix the adhesive tape, for example, to fix the patch.

In special cases of its implementation or use, the kit may include 4-10 measuring weights, 1-2 holders and 4-10 correction weights and contain a packing box or case.

The measuring weight in particular cases of its implementation or use may be made of gold, or of platinum, or of tantalum, or of an alloy of gold, platinum and tantalum; have a coating on a convex non-working surface 15, the color of which corresponds to the color of the skin; have an adhesive coating on a concave working surface 2; have a width of 3-7 mm, a thickness of 0.5-1.5 mm and a length of 6-24 mm.

The holder of the measuring weight in particular cases of its implementation or use may have spring jaws 5 and 6, which are equipped with a latch (not shown in the drawing) and / or have transverse transverse protrusions for the fingers 17 and 18.

The correction weight in particular cases of its implementation or use may have a convex non-working surface 16 with cylindrical or conical or spherical protrusions.

When working with the set, the protrusions 11 and 12 of the holder of the measuring weight are inserted into the grooves 13 and 14 of the first elongated plate 1, fix it by compressing the jaws 5 and 6 and set the concave working surface 2 on the outer surface of the eyelid.

To replace the originally installed measuring weight with a weight with a different weight, the protrusions 11 and 12 are reinserted into the grooves 13 and 14 of the first elongated plate 1 from the side of its convex idle surface 15, the plate 1 is fixed by compression of branches 5 and 6 and removed from the eyelid.

After determining the weight necessary to eliminate lagophthalmos, a correction weight is selected, the weight of which corresponds to the weight of the measuring weight.

A correction weight is mounted on the eyelid with a concave working surface 4 and secured with adhesive tape, for example, a plaster, which is fixed to the skin of the eyelid and to the outer convex non-working surface 16 of the second elongated plate 3. In this case, the concave surface 4 can be fixed with the plaster both independently and in combined with plaster fixation of a concave surface 4.

Example: patient Z., born in 1938, was admitted to the FSBI “NIIIGB” RAMS with a diagnosis of chronic facial nerve palsy, paralytic lagophthalmos, corneal opacity. Complaints during hospitalization of a “skewed” face, non-closure of the palpebral fissure on the left, periodic pain and lacrimation in the left eye. From the anamnesis it is known that, at the age of 51, he was operated on for a neoplasm of the cerebellum, after which paresis of the facial nerve on the left appeared. Over the years, she was repeatedly operated on the eyelids and on the cornea due to the development of a secondary (due to non-closure of the eyelids) corneal ulcer. Recently, there has been a significant increase in discomfort and pain in the left eye.

On examination: the right eye: the width of the palpebral fissure is 8 mm, the distance from the reflex of the cornea to the edge of the upper eyelid is 2 mm, the distance from the reflex of the cornea to the edge of the lower eyelid is 6 mm, an excursion of the upper eyelid is 14 mm, an excursion of the lower eyelid is 4 mm There is no lagophthalmos. The conjunctiva is calm. The cornea is transparent, shiny, arcus senilis.

The left eye: the width of the palpebral fissure is 10 mm, the distance from the reflex of the cornea to the edge of the upper eyelid is 2 mm, the distance from the reflex of the cornea to the edge of the lower eyelid is 8 mm, the tour of the upper eyelid is 12 mm, the tour of the lower eyelid is 0 mm, lagophthalmos 8 mm Pericorneal injection. Scars of the conjunctiva. The cornea is translucent, in the lower part of the epithelium is dull. Arcus senilis.

In 2011, in 2011, the eversion of the lower eyelid of the left eye was eliminated at the NIIIGB RAMS; after the operation, lagophthalmos decreased to 4 mm. In this connection, it was decided to eliminate the residual lagophthalmus using the proposed set. A double-sided adhesive tape was glued to the rear surface of a 0.8 gram measuring weight. The study was carried out in the position of the patient sitting at the slit lamp. To do this, they took the holder of the measuring weight, inserted its protrusions 11 and 12 into the grooves 13 and 14 of the previously prepared elongated plate 1 and fixed it by compressing the branches 5 and 6 and installed a concave working surface 2 on the skin of the upper eyelid. After fixing it to the skin of the eyelid, the holder was removed and measurements were taken.

When measuring a weight of 0.8 grams, the following data were obtained: the width of the palpebral fissure was 8 mm, the distance from the reflex of the cornea to the edge of the upper eyelid was 2 mm, the distance from the reflex of the cornea to the edge of the lower eyelid was 6 mm, lagophthalmos 2 mm. The initial installed measuring weight of 0.8 grams was replaced with a measuring weight of 1.0 grams. For this, the protrusions 11 and 12 were reinserted into the grooves 13 and 14 of the first elongated plate 1 from the side of its convex non-working surface 15, the plate 1 was fixed by compression of branches 5 and 6 and removed from the eyelid. Further, according to the previously described method, the holder installed a measuring weight of 1.0 gram, on which a double-sided adhesive tape had previously been attached.

When using a measuring weight of 1.0 g, the following data were obtained: the width of the palpebral fissure is 8 mm, the distance from the reflex of the cornea to the edge of the upper eyelid is 2 mm, the distance from the reflex of the cornea to the edge of the lower eyelid is 6 mm, lagophthalmos 0 mm. The absence of lagophthalmus at this weight of the measuring weight allowed us to use this weight in the future. The measuring weight was removed by the holder.

After determining the minimum weight necessary to eliminate lagophthalmos, we selected a correction weight of identical weight to the measuring weight, in this case 1.0 gram.

Correctional 1.0 gram weight was installed on the upper eyelid with a concave working surface 4 and fixed with a plaster, which was fixed to the skin of the eyelid and to the external convex non-working surface 16 of the elongated plate 3. The data obtained made it possible to recommend the patient to use the correction weight independently, which the patient subsequently did. The application of this technique and the proposed set allowed non-surgical correction of residual lagophthalmos.
