Description

The invention relates to the field of medical equipment, namely to ophthalmology, and is intended for plastic and reconstructive microsurgery of the eye in mobile structures in sparsely populated areas, in medical institutions not equipped with specialized equipment for ophthalmic surgery.

It is known that the main difference between ophthalmic operating tables is the presence of a head restraint on which a head restraint mattress is located for the patient’s head, as well as a horseshoe-shaped table attached to the head rest, which is the support for the ophthalmic surgeon’s hands during the operation. The support is located around the patient’s head at the level of his zygomatic bones and allows the surgeon to fix his hands, remove excessive tension from the muscles of the hands, which increases the accuracy of movements and determines the quality of the operation.

Most ophthalmic operating tables come with head rests with hand rest included as a separate item (spare part). But due to significant differences in designs and ergonomics can not be used in combination with other tables.

For a number of circumstances, many district hospitals, especially in remote areas, do not have ophthalmic surgeons and, accordingly, specialized ophthalmic surgery equipment.

Therefore, patients are sent to medical institutions that have eye departments and ophthalmic surgeons, or to specialized eye clinics.

However, in local medical institutions, if they have general surgical equipment, in particular operating tables, medical couches, performing ophthalmic surgery, plastic and reconstructive operations that do not require high-tech surgical equipment, it is possible if they use devices for supporting the hands of an ophthalmic surgeon, resorting to the services of an invited person specialist.

Since the head restraints manufactured by the medical industry with an ophthalmic surgeon's palm rest are applicable only in conjunction with the original tables, the task is to create a device for fixing the ophthalmic surgeon's palm rest with a universal mount, which allows it to be fixed to the working surfaces of general-purpose operating tables and medical couches, as well as adapted for transportation.

The palm rest of the ophthalmosurgeon, depending on the design of the table, is either directly attached to the head of its working surface (ophthalmic table СОу633-МСК (МСК-633П) Меги: http: //medbuy.m/stol-operacionnyi-oftalmologicheskij/megi-sou633 -msk-msk-633p), or to the head restraint, which is mounted as an accessory (spare part) to the table (operating table "BIOMED" MT500 (Ophthalmic): http://medlabteh.net/p196484059-stol-operatsionnyi-biomed.html ; OAO ophthalmic operating table: http://www.panfundus.ru/operacionnve-stoly/AAOT.html).

Closest to the essential features of the claimed device is the head of the ophthalmic operating table "BIOMED" MT500.

The base of the head is made in the form of a metal frame with two brackets on the sides with screws for supporting, fixing and directing the vertical movement of the uprights of the palm rest. On the frame there is a panel with synthetic seamless upholstery to place a headrest mattress on it.

Two racks are attached to the horseshoe-shaped table for supporting hands from below by means of metal plates on the sides for vertical movement of the support. The working surface of the horseshoe-shaped table is covered with a thin polyurethane material with synthetic seamless upholstery.

The base of the head is bolted to the supporting frame of the operating table.

The horseshoe-shaped table is adjusted in height by fixing its racks with screws in the side brackets.

However, despite the fact that the head of the table is a separate product, for its connection to tables of a different configuration, the creation of special fasteners is required, which, given the variety of designs, is almost impossible.

The design of the head of the prototype table does not imply its horizontal movement, which creates discomfort for the patient being operated on, whose height is 2 meters or more with a total table length of 2000 mm.

In addition, the presence of two support stands at the horseshoe-shaped table is not necessary, because among the analogues there are tables where the ophthalmologist's palm rest is fixed on one stand.

The problem to be solved and the expected technical result is achieved using the claimed invention "A device for conducting ophthalmic surgical plastic and reconstructive operations in sparsely populated areas" (Fig. 1).

It includes a rectangular base 1 made of moisture-proof plywood 80 cm long, 60 cm wide, 8 mm thick, with four slots 2 arranged in pairs parallel to the sides for fixing the fastening belts 3, and a stainless steel plate 4 with dimensions 100 mm * 80 mm * 0 , 5 mm, located at the edge of the head of the base on the axis of its symmetry with a through hole 5 made through it with a diameter of 32 mm through it to move the ophthalmic surgeon's palm rest (Fig. 2).

The base coating is made of polyurethane in synthetic hygienic upholstery 6.

(Фиг. 3) для закрепления одной опорной стойки 10 из трубы нержавеющей стали диаметром 32 мм, длиной 350 мм и с наружней резьбой

, нарезанной в верхней части стойки на расстоянии 50 мм от края и в нижней части на расстоянии от края 150 мм.An ophthalmologist's palm rest is a panel 7 with a base of moisture-proof plywood measuring 360 * 360 mm, 6 mm thick, with a horseshoe-shaped cutout in the middle 8, 200 mm wide and 240 mm long, made 120 mm from the front edge of the panel, which is covered with polyurethane material in hygienic upholstery. A round stainless steel sleeve 9 with an internal diameter of 32 mm and an internal thread is placed at the bottom of the panel against the top of the cut

(Fig. 3) for fixing one support post 10 of stainless steel pipe with a diameter of 32 mm, a length of 350 mm and with an external thread

cut in the upper part of the rack at a distance of 50 mm from the edge and in the lower part at a distance from the edge of 150 mm.

и насечкой по боковой стороне (Фиг. 3), одна из которых располагается на стойке с верхней стороны основания, а другая - с нижней.Fastening the support column and moving it vertically through the hole in the base is done using two shaped round nuts 11, with thread

and a notch on the side (Fig. 3), one of which is located on the rack from the upper side of the base, and the other from the bottom.

The use of the device is as follows.

1. The base of the device is placed on the working surface of the operating table or medical couch.

2. Fixing belts, the locks of which are located on opposite sides of the base, are carried out under the panel of the table or couch and pass through the locks.

3. Level the device, gradually tightening the belts on each side to maximum force and fix it with locks.

4. Rotating the upper and lower shaped nuts on the support column in opposite directions, install the palm rest at a distance of 250 mm from the surface of the base.

5. After placing the patient on the operating table (couch), the height is adjusted by rotating the nuts and fixed by tightening the lower nut.

If necessary, the device’s fixation system allows you to change the total length of the patient’s location in the range from 180 to 210 cm.

Thus, the inventive device for supporting the hands of an ophthalmic surgeon allows surgical treatment of eye diseases in patients in sparsely populated areas in medical facilities in the absence of specialized ophthalmic surgical equipment in rooms that comply with sanitary norms and rules.

The simplicity of design and the minimum number of fasteners ensures the transportation of the device in disassembled form in a special package, its quick assembly and installation on site.
