RU214690U1 - Device for fixing the clip-fixator of the donor material of the eyeball on the slit lamp - Google Patents

Abstract

The utility model relates to medicine, specifically to ophthalmology, and is intended for stable fastening of a clip-fixator of donor material of the eyeball on a slit lamp. The technical result of the utility model is the ease of execution, ease of use and installation of this device in a slit lamp that does not require additional components. The technical result is achieved by the fact that the device for fixing the clip-fixator of the donor material of the eyeball on the slit lamp consists of a base in the form of a rectangular parallelepiped 120 mm long, 75 mm wide and 20 mm deep, made of a solid material, has holes on the sides that are made vertically through the entire thickness of the base, the distance between which is 90 mm, through the holes pass screws 125 mm long, which, when screwing nuts on them, rigidly fasten the base and a semi-ring in the form of an arc, made of elastic plastic material 12 mm wide, 50 mm high, with a diameter of 55 mm, the edges of the half-ring are bent at an angle of 90 degrees and have holes on their surface for screws that pass vertically through the entire thickness of the base and the half-ring, the ends of the screws act as support legs and are inserted into the holes from the bolts that secure the chin rest part to the slit lamp .

Description

The utility model relates to medicine, specifically to ophthalmology, and is intended for stable fastening of the clip-fixator of the donor material of the eyeball on the slit lamp, which will allow various surgical manipulations to be performed on the donor material for educational purposes using tools, as well as using laser devices built directly into the eye. into a slit lamp.

Closest to the proposed utility model is the cadaveric eye fixator - patent for invention SU 1804432. The fixator contains a stand with supporting elements for the cadaveric eye placed in it, for the purpose of simplicity and convenience, the supporting element is made in the form of a sleeve with a spherical recess for the eye and is fixed on the stand with the possibility of rotation around an axis located at an angle to the base of the stand. The disadvantage of the prototype is that it is designed only for taking histological material from a cadaveric eye, not intended for fixation on a slit lamp, which does not allow technically complex surgical manipulations for educational purposes, as well as the use of laser devices.

The objective of the utility model is to create a device that makes it possible to fix the clamp-fixator of the donor material of the eyeball with the donor material placed into it, on a slit lamp, for conducting various surgical manipulations on the donor material for educational purposes using surgical instruments, as well as using a built-in laser in the design of the slit lamp.

The technical result of the utility model is the convenience of using and installing a device with a clamp-lock with donor material placed in it in a slit lamp for surgical manipulations for educational purposes.

The technical result is achieved by the fact that the device for fixing the clamp-fixator of the eyeball donor material on the slit lamp consists of a base in the form of a rectangular parallelepiped 120 mm long, 75 mm wide and 20 mm deep, made of solid wooden material, can be made of solid plastic material, has holes on the sides that are made vertically through the entire thickness of the base, the distance between which is 90 mm; elastic plastic material 12 mm wide, 50 mm high, 55 mm in diameter, the edges of the half-ring are bent at an angle of 90 degrees and have holes for screws on their surface that pass vertically through the entire thickness of the base and the half-ring, the ends of the screws act as support legs and are inserted into holes from the bolts that secure the part of the pick bottom on a slit lamp.

A “window” is formed between the base and the half-ring, where the clamp-fixator of the donor eyeball material is placed, by tightening the nuts on the screws, the base and the half-ring are rigidly fastened to each other, which guarantees the stability and immobility of the clamp-fixator of the donor eyeball material in the device. The fastening screws pass vertically through the entire thickness of the base and the half-ring, the ends of the screws act as support legs and are inserted into the holes from the bolts that secure the chin rest part to the slit lamp. The distance between the holes for fixing the chin rest on the slit lamp should correspond to the distance between the screws in the device for fixing the clip-fixator of the donor material of the eyeball on the slit lamp and be equal to 90 mm.

Thus, the proposed device for fixing the clip-fixator of the donor eyeball material on the slit lamp is unique in its kind and will allow various surgical manipulations to be performed on the donor material using instruments, as well as using laser devices built directly into the slit lamp.
