Abstract

A scoliometer consisting of a bar compass and a gravimetric sensor-goniometer, characterized in that the bar compass and the gravimetric sensor-goniometer are functionally connected to each other, the legs of the bar compass are rounded, the gravimetric sensor-goniometer is movably connected to the graduated bar and can record spinal curvature in three mutually perpendicular planes.

Description

Device for measuring curvature of the spine

The utility model relates to medicine, namely to anthropology and can be used for measurements

the spine.

For measurement, the Mollison slope goniometer is known, consisting of a graduated metal plate connected to a flat cross plate, in the center of which there is an arrow with a hole. The arrow rotates on the screw and, thanks to the hole, the axis maintains a vertical position. On the back side of the main plate there is a clip with a screw, into which a leg of a sliding or thick compass is threaded. When the main plate is brought out of a horizontal position, the arrow deviates by a certain angle, showing the deviations of the measured line from the horizontal and vertical plane (V.V. Bunak Anthropometry, 1941, p. 34-35).

The disadvantage of this device is that it allows you to measure only in two planes and is a stationary device that does not allow serial measurements, for example, when examining children and adults in field studies, since the device is intended for stationary examination. In addition, the measurement of the plumb line angle decreases the accuracy of the measurements.

(scolimeter) The purpose of the invention is to improve the accuracy of measurement of distortions

spine in three planes.

The goal is achieved due to the fact that the barbell compass and the gravimetric sensor-goniometer are connected functionally to each other, the legs of the bar-shaped compass are rounded, the gravimetric sensor-goniometer is movably connected to the graduated bar and can fix the spinal curvature in three mutually perpendicular planes.

The scolimeter is a tool consisting of two parts: a rod compass (7) with two legs (2), one of which is movable relative to a ruler with millimeter divisions from O to 430 mm (1) and a head for measuring angular dimensions from -40 ° to +40 (3).

To measure the linear dimensions of the legs of the compass (2) set on the measured points and measure on a linear scale (1) in the range from O to 430 mm, and the legs (2) are made rounded to prevent injury to the skin of the subject.

To measure the angular dimensions on the back wall of the head, it is necessary to turn the bar fixing the arrow by 180. Then set the legs (2) on the measured points and on the head scale determine the angle of curvature of the measured points. For ease of measurement, the head can be rotated around its axis (6) by 180 °, and also in the plane of the linear scale by 90. The rotation of the head around the axis of the probe1 is fixed; Fixing

turning the head 90 is carried out by a screw mounted on the bottom of the head. After carrying out all measurements, it is necessary to fix the arrow (5). Turning the bar, it is located on the rear wall of the head, 180 °. Secure the measuring head with a screw.

The device operates as follows: to measure frontal scoliotic curvature of the spine, the bearing bar (1) of the scolimeter is set vertically using a goniometer sensor (3), control is carried out by axial movements of the goniometer; using telescopic rods (2) oriented in the sagittal plane, their thrust nozzles are led by tilting the carrier bar in the frontal plane and move them along the carrier bar to the intended measurement points;

4, when the persistent nose of the scolimeter (2) comes into contact with the measuring points on the sensor-goniometer (3), oriented in the frontal plane, the angle is recorded;

4 graduated bearing plate (1) allows you to record the distance between the rod-points of registration of the angle; 4 Similarly, after reorienting the device, sagittal curvature of the spine can be measured.

Scolimeter parts are made of D16T grade aluminum alloys with subsequent chemical nickel plating and polishing, which provides reliable corrosion protection and mechanical strength of the coating during operation. New technical solution with a scale (1). New clinical effect:

4 measurement accuracy in three planes of spinal curvature;

 the possibility of examining various population groups in any

conditions;

F portability and low cost 4 device supply graduated
