Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a therapeutic traction device used to treat diseases caused by abnormalities of the cervical vertebrae.

In conventional traction therapy for the cervical vertebrae, a traction neck brace attached to the patient is simply pulled forward and upward in front of the patient for the purpose of enlarging the rear side of the cervical vertebrae.

The central nervous system passes through the vertebral foramen on the back side of the cervical vertebrae, branches out from the vertebrae, and connects to various parts of the body via the medullary nerve grooves on both sides of the back of the vertebrae that form the cervical vertebrae. Therefore, cervical traction therapy is effective when performed by enlarging the interval between the medullary nerve grooves on the right or left rear side of the cervical vertebrae and relieving pressure on the nerve bundles.

However, conventional cervical traction devices only pull the patient's head forward and upward, widening the gap between the cervical vertebrae and expanding the posterior cervical vertebrae. Alternatively, it was not possible to selectively enlarge the medullary nerve groove on the left posterior side, and only one effective method was possible.

Therefore, an object of the present invention is to provide a cervical traction treatment in which the traction direction of the cervical vertebrae can be accurately adjusted and set to an appropriate diagonal, horizontal, forward, and upward direction as needed, and the angle setting operation is easy.

The operation of the present invention with the above configuration will be explained in detail below.

First, the general procedure for performing traction treatment will be explained.

A patient undergoing treatment for the cervical vertebrae sits on the chair 1, a neck brace 35 is attached to the patient's head, and a traction cable 34 extending from a traction machine body 62 is connected to the neck brace 65 via a pulley 29. do.

In order to make the direction of traction with respect to the cervical vertebrae obliquely horizontal, forward and upward, the shoulder fixing device 17 is brought into contact with the patient's shoulder and then fixed to determine the height of the cervical vertebrae, and the chair 1 is slid back and forth on the rail 24 to move forward. The upper traction angle is set, and the chair 1 is rotated left and right around the upright axis to set the lateral and upper traction angle.

When the position of the chair 1 is set and the traction angle of the cervical vertebrae towed by the traction rope 34 pulled out from the fixed position of the pulley 29 is determined, the traction machine main body 62 is operated to perform traction treatment.

To explain in detail the function of the shoulder fixing device 17 mentioned above, the shoulder fixing device 17 provided on the backrest 2 of the chair 1 slides downward from above and comes into contact with the eyebrows of the patient sitting on the chair 1, and further removes debris. Fixture 17
is moved in and out of the backrest 2 side, and the patient's mouth 14 is fixed to the backrest 2. At this time, the cervical vertebrae are fixed so as to be located on the extension line of the pillar 5. Tighten the tightening knob bolt 21 and remove the holder 2.
Fix the vertical movement of 0, and use the tightening handle 22 to tighten the shoulder fixture 17.
Fix the forward and backward movement of.

A backrest marking 37 attached to the back of the backrest 2 is detected by a height sensor 68 to know the height of the shoulder fixture 17.

Further, to explain in detail the sliding movement of the chair 10 in the front and rear directions, the sliding movement of the chair 1 is sequentially transmitted to the driving gear 46 and the passive gear 42-'X of the sliding gear motor 9 of the sliding power mechanism 40. The position of the chair 1 is determined by detecting the screw shaft marking 27 with a sliding position sensor 28.

In addition, to explain in detail the above-mentioned 10-time movement of the chair, the driving force of the rotation geared motor 14 in the rotation power mechanism 15 is used to move the seat 6 and backrest 2 of the chair 1 to the worm gear 13, the worm wheel 9, and the support of the chair 1. 5 and rotates the seat 6 and the backrest 2 supported by the pillar 5. A support marking 10 attached to the support 5 is detected by a rotation angle sensor 11 to know the rotation angle of the support 5. A method of searching for the optimal cervical traction angle for a patient using this device that operates as described above will be described next.

After the fetal fixation device 17 is brought into contact with the shoulders of the patient sitting on the chair 1, a push button switch (not shown) provided on the control unit 36 is pressed.
etc., the sliding power mechanism 40 and the rotation power mechanism 15 are operated to move the chair 1 at will to search for a cervical traction angle suitable for the patient.

As an example of a method for facilitating the search for the traction angle, the table shows the positions where the basic traction angle is generated.Positions A (sheep rotation angle = 60 degrees at the forward tilt angle f = 5 degrees) to positions ff1l
(At the position of the forward tilt angle f220 degrees, the counterclockwise rotation angle = 30 degrees) are predetermined at 20 locations, and push button switches AS to TS corresponding to these positions A to T are arranged in Fig. 7. A switch panel 26 shown in FIG. 1 is provided in the control section. Insert button switch A
After selecting the basic angle using the S-TS suppression operation, fine adjustments are made to search for the traction angle.

When the search is completed, the chair 1 is fixed at the searched position and the traction machine main body 62 is operated to perform a volumetric treatment of the cervical vertebrae.

The traction angle is always displayed on an appropriate display (not shown) of the control unit 66 while the device is in use.

i! The method of setting the position of the chair 1 so that the chair 1 can be pulled at a predetermined pulling angle that is optimal for each individual is to set the circumferential fixing device 17 and then press the thumb rotary switch (not shown) provided in the control section 36. Input and set the tilt angle and rotation angle and start. Then, the control section 36 calculates the detected values from the sliding position sensor 28, height sensor 38, and rotation angle sensor 11, and sends control signals to the sliding power mechanism 40 and the rotation power mechanism 1de. The chair 1 is automatically moved to a position where a predetermined traction angle can be obtained while giving.

After the traction treatment, the waste fixing device 17 is moved to the upper limit, and a reset button (not shown) provided on the control unit 36 is operated to return the chair 1 to the initial position. That is, the support 5 of the chair 1 is the pulley 2.
9 is returned to the position R1, that is, the forward tilt angle is zero, and further, the front of the chair 1 is returned to the position toward the end of the rail 24 connecting the traction machine body 62, that is, the position where the rotation angle is zero. This reset operation can also be linked to the operation of the traction machine main body 62 so that the chair 1 is returned to the initial position at the same time as the traction operation is completed.

Next, the method of detecting the position of the erasing fixture 17 and the position and angle of the chair 1 will be explained in detail. First, the position of the shoulder fixture 17 is detected by a distance indicating the sliding distance as shown in FIG. A backrest marking 67 marked with a mark row 44 and a direction mark row 45 indicating the sliding direction is detected by a height sensor 38 provided as a set of two sensors.

First, the shoulder fixture 17 is slid to the upper limit position, and the detected value at this position is taken as the reference value of the shoulder fixture 17. By lowering the shoulder fixture 17, the height sensor 68 detects the distance traveled by the shoulder controller 66, which subtracts the detected value from the reference value to calculate the height of the cervical vertebrae. When raising from a position once lowered, the distance traveled is detected, and the control unit 36 adds the detected value.

Furthermore, the sliding distance of the chair 1 on the rail 24 is detected by the sliding gear motor 39 that slides the chair 1 from the initial position.
At the same time as the normal rotation is instructed, the sliding direction to the front is instructed to the sliding position sensor 28, and the sliding distance is detected. When the chair 1 is to be slid back and forth on the rail 24, the forward and backward sliding direction is instructed to the sliding position sensor 28 at the same time that the sliding gear motor 9 is instructed to rotate forward or backward, and the forward and backward sliding distance is determined. Detected.

Further, the rotation angle of the chair 1 is detected when the rotation angle sensor 11 indicates the clockwise or counterclockwise rotation direction of the support at the same time as the rotation geared motor 14 which rotates the chair 1 from the initial position is instructed to rotate forward or reverse. is instructed and the rotation angle is detected.

The effect of the device according to the above-described configuration and operation is that after fixing the patient's cervical vertebrae to the chair, the chair is slid on a rail and then rotated. The ability to enlarge the lateral side of the rear of the cervical vertebrae and enlarge the space between the vertebrae of the cervical vertebrae, which could not be achieved with a device, makes it possible to easily search for an appropriate traction angle for each individual and perform traction therapy.

In addition, it is possible to accurately reproduce the pulling angle with easy operation of the control unit, and while recording the appropriate pulling angle, it is possible to perform extremely effective and pain-relieving traction treatment. .
