Description

The present invention relates to a lumbar traction device used for lumbar traction treatment, and in particular, traction capable of performing safe and effective traction treatment with a person to be treated in an optimal posture during traction. An object is to provide an apparatus.

Lumbar traction therapy treats lumbar disease by supporting and fixing the sides and pulling the pelvis, and is widely used in fields such as orthopedics and rehabilitation.

An example of a conventional lumbar traction device is shown in FIG. FIG. 6A shows a type using a flat bed, and FIG. 6B shows an improved version.

The apparatus of FIG. 6 (A) is composed of a pulling bed 50 and a puller body 51, and uses a side brace 54 and a waist brace 53 as an aid for treatment.
The bed is usually placed on the frame 57 by dividing the mat into two. The mat 55 on the upper body is almost fixed to the frame 57, and the lower limb side mat 56 is movable along the frame 57 in the length direction of the bed (the patient's height direction). The lumbar vertebra is positioned at the boundary between the mat 55 on the upper body and the mat 56 on the lower leg.

Before treatment, the patient rests on the bed and is in a supine position. The waist brace 53 is attached to the waist (pelvis) and connected to the traction device 51 via the traction wire 52. Also, the armpit 54 is fixed to the side so that the body does not slip during towing. When the traction device 51 is operated in this state, the lumbar vertebra can be pulled because the side is supported.

As shown in FIG. 9, when the treatment is started, the traction is paused for a predetermined time (referred to as the pause mode. The pause time is referred to as the pause time). Towing (referred to as towing mode). The traction force is generated by driving the motor of the tractor body 51 and winding the traction wire (52). When the traction force reaches a set value, the motor is stopped for a predetermined time and the traction force is maintained (referred to as “sustained mode. The duration time is referred to as“ duration ”). When the continuous mode ends, the motor is rotated backward to loosen the traction force (referred to as a relaxation mode). When the traction force becomes zero or less than a predetermined value, a pause is performed, and this is repeated until the treatment time ends. Such repeated traction is referred to as intermittent traction.
In some cases, traction is started, and this traction force may be maintained for a treatment time while initially pulling to a set value. This is called continuous traction.

Such traction conditions (traction force, treatment time, duration, rest time, etc.) are performed by operating a key switch or volume provided on the operation unit of the operation panel of the apparatus. Some are set using a memory card.
Information on the operation unit is sent to the control unit of the apparatus, and based on this information, the control unit controls the entire apparatus, including the time for the traction motor and treatment, and performs predetermined traction treatment.
The elapsed time of traction treatment and the traction force at that time are displayed on a display provided on the panel surface.

Although not shown in FIG. 6 (A), in actual treatment, as shown in FIG. 8 (A), the knee is bent and a leg stand K is laid under the knee to perform traction. In this way, treatment is performed with less lumbar curvature (front bay). The reasons for the treatment without the front bay are as follows.
Usually, the person is standing and the lumbar spine is slightly in front. However, the upper body is always loaded with the upper body in the standing position. Especially when the level of the front bay is large, the load is concentrated on a part of the body, and back pain is likely to occur. There are various types of low back pain, such as myofascial low back pain and disc herniation, all of which often occur at the back of the lumbar spine.
Lumbar traction treatment is effective for this treatment, but if traction is performed with the front bay left, usually traction is performed intermittently, causing stress to the affected area repeatedly, which causes damage and lower back pain. May be exacerbated. For this reason, as shown to FIG. 8 (A), the attitude which corrected the front bay is appropriate, and it is important to treat in this state. If the angle between the lumbar region and the thigh region and the knee flexion angle are 90 degrees, the lumbar vertebra is linear, and even if intermittent traction is performed, there is little damage to the affected area.

While traction therapy is effective, problems remain with the device.
In the apparatus of FIG. 6 (A), before treatment, the patient gets on the bed, wears the brace, is in the supine position, and puts the footrest under the knee. It is necessary to perform the reverse operation after treatment. However, for patients with back pain, performing these actions was physically painful.
In addition, it took time and effort to wear the brace, and it was troublesome not only for the patient but also for the caregiver.
In order to solve these problems, there is one in which the bed is shaped like a chair and the patient simply sits on the chair (see, for example, Patent Document 1).

FIG. 6B shows an example of Patent Document 1.
The apparatus has a dorsal part (8 in FIG. 6 (B)) on which the patient's upper body (from the back to the head) is placed and a seat part (16 in FIG. 6 (B)) on which the patient's lower body (from the buttocks to the lower limbs) is placed. ) To form a rack (2 in FIG. 6B), place the rack on the base (1 in FIG. 6B), and tilt the mechanism (3 in FIG. 6B). The platform is tilted to the traction position that is reclined from the sitting position by a predetermined angle.
The depth of the seating portion (6 in FIG. 6B) corresponds to the height of the leg base K used during conventional traction shown in FIG. 8A.
When the traction mechanism part (10 in FIG. 6B) is operated in the traction position, the seat part moves along a seat frame (15 in FIG. 6B) from the back part in a predetermined direction (about 10 to 20 degrees). It moves to the frame (4 in FIG. 6B) and the seat frame (determined by the angle formed by 15 in FIG. 6B) to generate traction force. In practice, intermittent traction is often performed by reciprocating the seat.
There is a method of fixing the seat and moving the backrest, but there is essentially no difference.

The seat portion is provided with a belt (B) as a waist fixing means, and the pelvis portion is fixed to the seat portion with this belt. Actually, the part of which the peripheral size is smaller than the pelvis is pulled from the pelvis to the waist so that the pulling device does not slip. In addition, a pair of arm for arms (13 in FIG. 6B) is provided on both sides of the dorsal part to support both sides of the patient.
As shown in FIG. 7A, the arm for side is rotated in the direction of arrow T and is set near the position of the side to support the side. When the patient gets on and off, the arm for side can be rotated in the direction of arrow T and retracted to a position where it does not get in the way. Moreover, as shown to FIG. 7 (B), it can set to the side position vicinity, can be moved to the position which supports a side by parallelly moving to the head side in the length direction of a bed. For this reason, even if the height is different, support the armpits.
7A and 7B can be automatically performed by controlling the side arm 13 attachment portion T. That is, the arm for side can be attached and detached, or the movement to the retreat site can be performed automatically.

Although not shown, the apparatus is provided with an indicator that can provide an operation unit on the panel surface, set traction conditions, and display the progress of treatment, the current traction force, and the like.
Although not shown, the device is provided with a control unit that controls the entire device, and information input from the operation unit is sent to the control unit, and based on this information, time related to traction force and treatment is provided. Control etc.

Treatment is as follows.
Prior to the start of treatment, the traction conditions such as traction force, treatment time, duration, and rest time are input by operating the switches of the operation unit according to the disease state of the patient. It is also possible to store standard traction conditions in the control unit so that it is not necessary to input them again.
Subsequently, the patient is seated on the seat (6 in FIG. 6B), and the belt B is fastened to fix the buttocks to the seat. Basically, the pelvis is fixed and pulled, but there is also a method of pulling the lower limbs.
When a treatment start switch on the operation unit is pressed, a treatment timer is started and treatment is started.
First, the tilting mechanism part (3 in FIG. 6B) is activated, and the table (2 in FIG. 6B) tilts backward (reclining) to the traction position where traction treatment is performed.
In conjunction with this, as shown in FIG. 7A, the side arm drive unit Q operates during reclining, and the side arm is automatically moved from the retracted position (a position that does not interfere with getting on and off the head side). It rotates as indicated by the arrow T and moves so that the armrest 12 is in the vicinity of the backrest 8.
Further, the arm drive unit Q is operated to move from the initial position P0 to the patient's side position P1 , as shown in FIG. 7 (B), support the side with the armrest 12, and the body does not slip when towing. So that the side is fixed.
That is, the side arm can be automatically mounted.

Thereafter, the traction mechanism section (10 in FIG. 6B) is operated, and the seat section 16 is moved along the frame (15 in FIG. 6B) to perform lumbar traction.
The traction force is detected by the load sensor 9, and when the traction force reaches the set value, the traction mechanism (10 in FIG. 6B) is stopped and the continuous mode is entered.

When the duration timer reaches the set value in the duration mode, the relaxation mode is entered.
In the relaxation mode, the traction mechanism section (10 in FIG. 6B) is operated in the direction opposite to that during traction, and the seat section 16 is returned to the original direction (direction approaching the backrest 8). At this time, the traction force is detected, and when the traction force becomes 0 or less than a predetermined value, the traction mechanism is stopped and the sleep mode is entered.
This operation is repeated within the treatment time.

The angle between the backrest frame (4 in FIG. 6B) and the seat frame (15 in FIG. 6B) is about 10 to 20 degrees, and this is the angle in the towing direction (towing angle). It becomes. The pulling angle is set to the same level as that of the conventional apparatus shown in FIG.

The apparatus in FIG. 6B is the same as the conventional apparatus shown in FIG. 6A in that it supports the armpits and pulls the pelvis. Even if the arm is pulled while supporting the pelvis, the lumbar traction can be performed in the same manner, and there is no essential difference between the two.
However, since the patient only has to sit on the seat 6, the great pain when the person with low back pain gets on and off the bed 50 can be solved. Also, fixing the waist only tightens the belt, saving labor. The side fixation is automated since everything is aligned to the side of the patient, so it does not take time.

JP 2006-87853 A

Usually, a person's lumbar vertebrae are a little bit in front, which is important for supporting the upper body.
However, the waist is always stressed by the upper body load. In particular, if the degree of the anterior bay increases for some reason, the load concentrates locally at the back of the lumbar vertebra, and low back pain is likely to occur. There are various types of low back pain, such as myofascial low back pain and hernia, all of which compress nerves and muscles and cause pain.
Traction therapy is effective in treating such lumbar diseases.
However, because there is a large muscle between the front of the thigh and the abdomen, it is not possible to improve the front bay even if the legs are stretched and placed on the bed in the supine position. The bay is emphasized. As described above, towing with the front bay left may damage the affected area and exacerbate back pain.

In order to solve this problem and correct vertebral column shape appropriately for traction treatment, as shown in FIG. 8 (A), the angle between the lumbar vertebra and the thigh should be approximately 90 degrees. Place the footrest K with the appropriate height under the leg. In this position, the front bay of the lumbar vertebra is corrected and the lumbar vertebra becomes straight, so that traction treatment can be performed safely. In addition, since this posture allows relaxation, muscles such as the waist and abdomen do not contract, so that the traction force is efficiently transmitted to the lumbar spine and effective traction treatment can be performed.
That is, the posture shown in FIG. 8A is a posture suitable for traction, and when traction is performed in this manner, safe and effective traction treatment is possible. That is, in an actual traction device, it is desirable to use a table that matches the length of the thigh as shown in FIG. The pedestal may be a triangular pedestal as shown in FIG. 6A instead of the pedestal as shown in FIG. In short, it is important to perform traction treatment with the legs bent and the lumbar anterior bay removed.

However, since the conventional traction device uses a fixed-size pedestal K, the patient's leg length often does not match the height of the pedestal placed under the leg.
As shown in FIG. 8C, a person with a high height (leg length) has a thigh and the front bay is not sufficiently corrected. In addition, a part of the upper leg may hit the end of the lower leg placement part, and pain may occur. Pain can also occur in the same way because the heel also hits the local area. In addition, the legs are unstable in this state, and when trying to maintain this posture, force is applied to the lumbar region and the abdomen, and the traction force cannot be transmitted to the lumbar spine, so effective traction treatment cannot be performed.

On the other hand, as shown in FIG. 8D, in the case of a person with a short height, since the leg length is insufficient with respect to the base, the forward bending angle of the waist (angle formed by the waist and thigh) is tight. The lumbar spine becomes the back bay. If towing is performed in this state, a large load is applied to the rear part of the lumbar vertebrae, which may damage the tissue and is dangerous. Also, a part of the lower leg hits the end of the lower leg mounting part, and pain occurs. Even in this posture, since the lower limbs are unstable, force is applied to the lower back and abdomen, and the therapeutic effect is reduced.
The apparatus of FIG. 6 (B) is an improvement over the conventional FIG. 6 (A), but the size of the seating part (16 in FIG. 6 (B)) was fixed. For this reason, in the apparatus of FIG. 6 (B), depending on the patient's physique, as shown in FIGS. 8 (C) and (D), the leg length of the patient and the size of the seat portion do not match, and as shown in FIG. 8 (A). It was not possible to get a posture suitable for towing.

Examples of the present invention are shown below.

The invention according to claim 2 is a chair-like traction device as shown in FIG. 1, in which the depth (D) of the seating portion is matched to the length (L) of the patient's upper thigh to achieve an optimal posture for traction. A traction device that can treat
The apparatus includes a seat part (16) for supporting the patient's lower back and lower limbs, a seat frame 15 for placing the seat part (16), a dorsal part (8) for supporting the patient's back and head, A chair-shaped cradle (2) having a frame 4 on which the backrest (8) is placed;
A base (1) on which the base (2) is placed;
Provided between the base (1) of Gadai (2), Wo board (2) the locus a predetermined angle tilt mechanism unit causes tilting between tilt and traction position to the rear side (3),
A traction mechanism (10) provided between the seat (16) and the back (8) and generating a traction force by separating the distance between the seat (16) and the back (8) in a predetermined direction; ,
A waist fixing portion (B) provided on the seat portion (16) and fixing the pelvis to the seat portion (16);
A side fixing part (13) that supports the side and fixes the patient's body so that it does not slip during towing,
An operation unit having an input unit for inputting treatment conditions including traction force, and a display unit for displaying a set value and a current state;
In the lumbar traction device provided with a control unit for controlling the entire device such as the tilting mechanism unit (3) and the traction mechanism unit (10) based on information from the operation unit and information stored in the memory,
The seat part (16) is composed of a waist rest part (7), a seating part (6) and a crus rest part (5),
The crus placement part (5) or the seating part (6) is configured to be movable in the depth direction of the seating part (6), and the crus placement part (5) or the seating part (6) is configured as the seating part (6). A seat portion depth adjusting means (20) for moving in the depth direction of
The depth (D) of the seating portion can be adjusted to the length (L) of the patient's upper leg.
In FIG. 1, the lower back part (7) and the seating part (6) are integrated, the lower leg placing part (5) is separated, and the seating part depth adjusting means (20) is provided. The seating portion depth adjusting means (20) is not shown in the drawing, but the seating portion (6) and the crus resting portion (5) are coupled by a rail that slides in the depth direction of the seating portion, and along this rail. The lower leg placing part (5) is configured to be movable in the depth direction of the seating part.

When the seating portion depth adjusting means (20) is operated, the depth of the seating portion (6) can be adjusted. In FIG. 1, the seating portion depth adjusting means (20) is provided with a seating portion driving portion (18) to adjust the depth of the seating portion (6). In this example, a linear actuator is used for the seating section drive section (18).
When using a conventional footrest K with a fixed height, in a patient whose height is high, the lower limbs are not stable as shown in FIG. The lumbar traction was not effective. In addition, because the front bay remains, the affected area is stimulated by traction, and the disease may be exacerbated.

However, when the lumbar traction device described in this claim is used, the seating portion depth adjusting means (20) can be operated to adjust the depth of the seating portion (6), so that as shown in FIG. The length L of the upper leg and the height of the depth (D) of the seating part can be matched, and the posture optimal for traction treatment as shown in FIG. 8A can be obtained. For this reason, a lumbar vertebra can be made substantially linear and a safe treatment can be performed. In addition, since the lower limbs are stably placed on the lower leg placement part (5), the muscles can be relaxed without excessive force entering the waist and abdomen, and the traction force can be efficiently transmitted to the lumbar spine. Effective treatment. Furthermore, since a part of the lower limbs does not hit the edge of the lower leg placement portion (5), pain caused by local compression does not occur. In a patient whose height is low, conventionally, as shown in FIG. 8 (D), using a fixed foot platform K results in an unnatural posture, and as mentioned above, the muscles of the waist and abdomen are tense.
