Description

The invention relates to medical and rehabilitation equipment, in particular to physiotherapeutic devices for traction of the spine, designed for static and combined (static + vibrational) traction of the spine.

The design of the table of the traction motorized ORB Ormed Professional is known (Patent RU 2265427 C1 of 12/10/2005 IPC A61H 1/02). The basis of the table is a trapezoidal case, on which the movable and fixed sections of the couch are mounted. From both ends of the body are located levers of cervical and lumbar traction. The strap of Glisson and the chest belt are attached to the lever of cervical traction by belts. A pelvic girdle is attached to the lumbar traction lever with straps. A popliteal stand is mounted on the movable section of the couch. Traction force is controlled from the control panel and is controlled by a traction force sensor.

The main disadvantages of this design are:

- the body of the traction table with levers of cervical and lumbar traction excludes the possibility of stretching the spine of the patient in a vertical position, which limits the duration of traction in the presence of a flow of patients;

- a large number of kinematic relationships in the design of the exhaust device complicates maintenance and reduces the reliability of the device;

- reduced effectiveness of the procedure due to the fact that the process of placing the patient on the traction table in a horizontal position, especially during an exacerbation of the disease, additionally provokes pain in the spine;

- a decrease in the effectiveness of the traction procedure due to the fact that the patient, in order to move from a horizontal position in the Fowler position to a vertical one, after the procedure is completed, it is necessary to strain all muscle groups that were in a state of relaxation during traction and, accordingly, unauthorized loading of the diseased areas of the spine, which can return it to its original (pre-procedural) state.

Known design of the system for traction of the spine "TRAC-TIZER 2005" (SUPERTRAC)

(http://www.minato.ru/view.php?CID=4&ID=10 2007;

http://www.minato-med.co.jp/products/physical/stll.html 2007), which contains a table-chair consisting of a base and a swivel chair, an exhaust device consisting of an exhaust mechanism, a pelvic girdle and shoulder clamps, as well as a unit for vertical cervical traction, including a chair for cervical traction, a control panel, a system of rods and rods.

The main disadvantages of this design are:

- decrease in the effectiveness of the traction procedure due to the fact that the patient needs to bend the spine and, accordingly, unauthorizedly load the diseased areas of the spine in order to switch from a sitting position to a vertical position, which can return it to its original (pre-procedural) state;

- the use of shoulder clamps negatively affects the patient’s health and reduces therapeutic efficiency, since pressure is placed on the axillary region and deformation of the neurovascular bundles occurs, while the stretching procedure occurs in a patient state that is far from muscle relaxation;

- the presence in the composition of the system for stretching the spine of a separate block for cervical traction complicates the design and significantly increases the cost of the system.

The prototype is the design of the traction table Anatomotor (http://www.physiosport.ru/cgi-bin/shop.cgi?rzm=info&tvr 09.2007, http://www.hillchiropractictables.com 2007), containing a housing, which has a movable and fixed section of the couch, an exhaust mechanism that includes levers of cervical and lumbar traction with actuators located at both ends of the body. Glisson loop or chest belt are attached to the lever of cervical traction by belts. A pelvic girdle is attached to the lumbar traction lever with straps. A popliteal stand is mounted on the movable section of the couch. Traction force is controlled from the control panel and is controlled by a traction force sensor. The apparatus contains a vibration mechanism and a mechanism for turning the movable section of the couch upward by 85 ° to increase the efficiency of the procedure.

The main disadvantages of this design are:

- the body of the traction table with levers of cervical and lumbar traction excludes the possibility of stretching the spine of the patient in a vertical position, which limits the duration of traction in the presence of a flow of patients;

- reduced effectiveness of the procedure due to the fact that the process of placing the patient on the traction table in a horizontal position, especially during an exacerbation of the disease, additionally provokes pain in the spine;

- a large number of kinematic relationships in the design of the exhaust device complicates maintenance and reduces the reliability of the device;

- a decrease in the effectiveness of the traction procedure due to the fact that the patient needs to strain all muscle groups that were in a relaxation state during traction to move from a sitting position to the vertical after completion of the procedure, and, accordingly, unauthorized loading of the diseased areas of the spine, which may return it to its original (pre-procedural) state.

The task is to create an effective, mobile, simple and easy-to-use device for stretching the spine.

The problem is solved due to the fact that in the system of correction of the spine (UPC), consisting of an orthopedic table, which includes a body, couch and kneecap with footboard, couch rotation mechanism; the exhaust device, which includes the exhaust mechanism, head, chest and pelvic corsets, and control and management systems, the exhaust device is made in the form of an autonomous unit, fixed on the patient, and is a telescopic rod, on a fixed base of which the drive of the exhaust mechanism is installed and pelvic corset, and on the movable bar - chest or head corsets, the fastening design of which provides the ability to adjust their position depending on the patient's height. In this case, the vibrator is mounted on the upper end of the telescopic rod, and the couch is rotated 80 ° from a position close to vertical to a position close to horizontal, while the kneecap with a footrest by a system of levers is movably connected to the couch and the body for automatically transferring the patient to the Fowler posture and vice versa when turning the couch. The couch houses a heating system. The operation of the electric drive, vibration mechanism and heating system is controlled and monitored from the control panel.

The invention is illustrated by drawings, where:

figure 1 shows a side view of a device for stretching the spine;

figure 2 shows the appearance of the head corset;

figure 3 shows a side view of the orthopedic table.

A device for stretching the spine (figure 1) contains: a telescopic bar, a mechanism for changing its length, a removable head corset 4, a removable chest corset 5, a pelvic corset 7 and a vibrator 11. The telescopic bar consists of a base 1 and a movable bar 2. Depending on of the performed procedure, either a head corset 4 or a chest corset 5 is installed on the movable rod 2, which is rigidly fixed through the mounting holes using a removable pin-strain gauge 6. The pelvic corset 7 is fixedly mounted on the base 1. At the lower end of the angas 2 fixedly mounted nut 3 into which is screwed a bolt 9. The bottom part 9 of the bolt is rigidly connected to the gearbox output shaft 8 which is driven by the actuator 10. The screw 9 and the nut 3 form a screw pair. The rod 2 together with the nut 3 does not have the ability to rotate around the longitudinal axis, so the rotation of the screw 9 provides the translational movement of the rod 2. The vibrator 11 is installed in the upper end of the rod 2. The pelvic corset 7 and the chest corset 5 are fixed on the patient using straps 20.

On the control panel 12 sets the required tensile force between the pelvic corset and the chest or head corset. The pin strain gauge 6 perceives the magnitude of this effort. The signal from the strain gauge goes to the control panel 12. If the force does not correspond to the set, then a signal is supplied to the electric motor 10 to change the length of the rod. As soon as the force becomes necessary, the engine automatically turns off.

The head corset (figure 2) is made in the form of two rigid half-corsets 13 and 14, pivotally connected to each other through the carriage 15 and fixed on the patient in the closed position by the lock 16. On the half-corsets 13 and 14 are attached anatomical inserts 17 and 18 with removable sanitary pads 19.

The orthopedic table (Fig. 3) consists of a housing 21, a rotary couch 22, which is driven by a rotation mechanism 23 controlled by a control panel 12. The rotary couch 22 consists of a fixed part 24, a movable part 25, and a kneecap 26 that rises when using the lever system 27. In the movable part 25 of the swivel couch 22, a heating element 28 is integrated, which is controlled by the control panel 12.

The procedure for stretching the spine of the patient is carried out in the following order. Before starting the procedure, the swivel couch 22 is in a vertical position. A pelvic corset 7 is fixed on the patient and, depending on the purpose of the procedure, a chest 5 or head 4 corset. Then the patient stands on the step of the kneecap 26, his back to the couch, after which the rotary couch 22 with the patient, on command from the control panel, is moved to a horizontal position, while the kneecap 26 with the help of the lever system 27 raises the patient's legs, transferring him to the Fowler posture. On the control panel 12, traction parameters are set: traction force and time, vibration load options and heating temperature, after which traction begins.

The load is removed from the spine and the patient is moved to a vertical position from the control panel 12.

Features of the device are:

- simplicity of design and ease of use;

- high efficiency provided by the ability to place the patient on an orthopedic table in an upright position before and after the traction procedure, which completely eliminates unauthorized effects on the diseased areas of the spine before and after the procedure

- mobility of the exhaust device, made in the form of an autonomous unit and allowing to carry out the stretching procedure in a vertical or other position convenient for the patient
