Description

one

The invention relates to medical technology, in particular to the supports used in surgical interventions and operations to give a part of the patient's body the desired elevation.

A medical stand is known, containing opera and movable plates and a movable plate lifting mechanism.

The main disadvantage of the known medical support is the complexity of its design in the form of rails, gears and a large number of levers. Along with this, during the operation with the use of this stand, the surgeon is not able to change its height itself due to the long length of the handle.

The purpose of the invention is to simplify the KOHC-IW operation of the medical stand.

The goal is achieved by the fact that in a medical stand containing supporting and movable plates and a lifting mechanism of a movable plate, a lifting mechanism

made in the form of a screw-nut transfer and two lever parallelograms, the movable plate being concave in the shape of the human shoulder and has openings for fixing various sizes.

In the drawing, the device is shown in three projections.

The medical stand, intended for use in various surgical investigations, interventions and operations, contains a movable plate 1 quadrangular ({jurma, concave under a radius of 127 ~ 1280 mm (the radius and dimensions of the plate are selected on the basis of anthropometric research and calculations) with rounded and the edges bent under the radius of 6-8 mm, and the supporting plate 2, which are connected hingedly with the parallelogram 111arnofnymi links 3 and 4. Each link consists of four identical metal plates with holes on the for screw swivel interconnection.

The upper and lower hinges of the parallelogram links are fixed with the movable 1 and supporting 2 plates, and the opposite sides of the middle hinges are joined by four identical sleeves 5, having a hole in the middle of the blade through which the screw 6 of two parts passes with oppositely directed threads. The inner ends of the two screw parts in the middle of the device are connected by a clutch 7, consisting of two mating parts that have inside-engraved threads, and the outer ends are terminated by handles 8 and 9. The moving plate 1 can be located at an operating distance of 5O-120 mm and 5О-2ОО mm. Gradation millimeter. In order to make the device universal for children and adults, four holes 10 are made on the movable plate 1, two on each side of its middle third, for fixing patch plates of large sizes for older children and for ADULTS

The device is made of non-corrosive stainless steel. During the operation, the device is placed on the operating table under the shoulders or another part of the patient's body, then its height is adjusted by turning the knob, and thus the desired raised position is attached to the desired part of the patient's body. If necessary, in the course of an operation or other surgical intervention (tracheobronchoscopy, etc.), the surgeon easily changes the height of the device by rotating the handle, without disturbing the operation. The device is simple in construction, convenient to use.
