RU14353U1 - DEVICE FOR EPIBULAR EYEBALL ANESTHESIA - Google Patents

Abstract

A device for epibulbar anesthesia of the eyeball, containing a ring, characterized in that it further comprises a cylindrical body with a bottom, in the center of which a rod is located perpendicular to it, while the inner diameter of the cylindrical body is 3-5 mm larger than the outer diameter of the ring, and the diameter of the rod 2-4 mm less than the inner diameter of the ring, while the ring is made of hard material with a handle-holder, the inner surface of the working part of which is made with a radius of curvature congruent to the radius k rivals of the sclera and vertical annular groove.

Description

A useful model related to the field of medicine, and more specifically to ophthalmosurgery, can be used for epibulbar anesthesia for photorefractive keratectomy (PRK) and laser keratomilbose surgery

A device for anesthesia of the eyeball during abdominal operations. The device is made of hydrophilic material in the form of a ring with an inner diameter slightly larger than the diameter of the cornea. The device is impregnated with a solution of anesthetic (marcain) and is fixed perilimbally with sutures. (see Journal of Cataract and Refractive surgery, 1995, vol. 21, p. 16-20). However, this device cannot be used for epibulphic anesthesia during PRK and laser keratomil a.

The technical task to be solved is to exclude contact of the anesthetic and its side effect on the corneal epithelium, increasing the quality of epibulbar anesthesia in PRK and laser keratomyelosis.

The technical result is achieved by the fact that the device

for epibulbar anesthesia of the eyeball during PRK and laser keratomilbse operations, it is made in the form of a ring, it differs in that it additionally contains a cylindrical body with a bottom, the center of which and the rod is located perpendicular to it, while the inner diameter of Go) of the cylindrical body is 3 l more, - -

5 mm, the outer diameter GV2) of the ring, and the diameter (JD3 / rod is less than 1 2-4 mm. Of the inner diameter (O4 / ring,

the ring is made of hard material with a handle-holder, the inner surface of the working part of which is made with a radius of curvature congruent to the radius of curvature of the sclera and a vertical annular groove.

The utility model is illustrated by a drawing (Fig. 1), which shows the ring 1, the handle-holder 2, the cylindrical body 3 with the rod 4, the inner surface 5 of the working part of the ring 1, the groove 6.

The work with the proposed device is carried out as follows:

Holding the handle 2 of the ring 1, the surgeon for 1-2 seconds. ring 1 in the cylinder housing 3 with anesthetic solution will interfere. Then the ring 1 is removed from the housing 3. Anesthetic remains in the groove 6. By light pressure and slight oscillatory movement, ring 1 is fixed for 1-2 seconds. on the scleral area of the patient’s eyeball, so that the inner diameter of the ring D4 is at a distance of 1-3 mm. from the limb of the cornea. In this case, the anesthetic due to the adhesion forces remains on

prilimbal conjunctival and absorbed. This method of applying an anesthetic eliminates its contact with corneal epithelium.

Using the proposed device allows eliminating the side effect of anesthetic on corneal epithelium 1FI during PRK and LASIK, increasing the reliability of epibulb anesthesia and improving the functional results of these operations.
