Description

[Detailed Description of the Invention] This invention relates to a traction device for a column, which is mainly used for the treatment of lateral columnar disease, intervertebral disc herniation, and the like.

The treatment method of immediately lengthening the pillars by traction has a number of advantages that other, for example, surgical techniques do not have.

To accomplish this, place the lower band around your waist and/or legs, place the band around your neck, and pull the neck band upward and the lower band downward.

FIG. 1 shows typical traction devices already in use.

This traction device connects one end of a traction rope 1 to a leg band 2,
The other end is connected to a neck band 3, and to this traction rope 1 is connected a traction rope 1 connected to a grip 4 that is pulled by hand, and this traction rope 1 is connected to pulleys 5 attached to both ends of the bed.
The neck band and leg band 2 are pulled in opposite directions by pulling the neck band and leg band 2 over the neck band and pulling the hand or foot.

However, with this structure, the neck band 3 was pulled strongly, causing pain to the cheekbones on which the neck band 3 was hung, and there was even a risk that the cheekbones would become deformed if pulled for a long time.

This is because the people who drive this kind of equipment are mostly minors who are in their growth stages, who are junior high school students or younger.

This device was developed to eliminate this drawback, and the traction force of the neck band was weaker than the force of the leg band to pull the pillar downwards.The important purpose of this device was to The object of the present invention is to provide a pillar traction device that can be attached to a bed and can be comfortably pulled for a long time without worrying about cheek pain or cheekbone deformity even though the pillar can be effectively pulled.

Hereinafter, embodiments of this invention will be described based on the drawings.

The pillar traction device attached to the bed shown in Figure 2 is
A neck band 3 that can be hung around the neck, a leg band 2, a waist band 6, and a leg traction rope 1 whose end is connected to the waist band 6.
B, a neck traction rope 1A whose end is connected to the neck band 3, and a main traction rope consisting of the neck traction rope 1A and the leg traction rope 1B, which connects the neck band and the leg band 2.
and a pulley 5 that pulls the waist band 6 in opposite directions.
, a grip 4 connected to the end of the main traction rope, and a movable pulley 7 on which the leg traction rope 1B is hung and whose rotating shaft is connected to the waist band 6 via the sub traction rope 1C.

The neck band 3 is made of leather that is hooked around the neck of the patient lying supine on the bed, more precisely around the cheekbones and the back of the head.The waist band 6 is a band that is wrapped around the waist, and one end of the leg traction rope 1B is detachably hooked on both ends. The leg band 2 is
It is a band that is wrapped around the ankle.

There are two sets of main traction ropes, and the leg traction rope 1B, whose end is connected to the leg band 2, has a spring 8 connected in the middle, and both ends of the spring 8 are shorter than the length when the spring is at its maximum extension, and are stored. They are connected by a string 9 that is longer than the actual length, and are branched into two on the lower side, hung separately on two movable pulleys 7, and their tips are connected to the waist band 6.

The upper side of the spring 8 is branched into three parts, and the upper end of the center is connected to the neck band 3, and by pulling the leg band with the foot, the waist band 6 and the neck band 3 are pulled in opposite directions.

Two sets of main traction ropes are connected to the grip 4, one end of the neck traction rope 1A is hung on the neck band 3, and the other leg traction rope 1B is hung on a movable pulley 7, with one end attached to the waist band 6. They are connected.

A neck traction rope 1A and a leg traction rope 1B are hung on pulleys 5 attached to both ends of the bed.The attachment positions of these pulleys are such that the neck band 3 pulls the patient's neck upward and the leg bands 2 and the waist band 6 to pull the patient's legs and waist downward.

In the pillar traction device shown in FIG. 2, the neck traction rope 1A is routed around the top of the bed, and the leg traction rope 1B is routed from the top to the bottom through the back of the bed.

The movable pulley 7 is hung with a leg traction rope 1B, and
The rotating shaft is connected to the leg band 2 via the sub traction rope 1C, and pulls the leg traction rope 1B with a tension that is half of the traction force of the leg band 2.

For example, if the pillar traction device attached to the bed configured in this way pulls the leg band 2 with a force of 4 kg by retracting the legs, the leg traction rope 1B has a force of 2 kg, half of this amount.
A tension of kg is applied, and arm band 6 and neck band 3 are 2k.
It is pulled by the force of g, and the total weight is 6 kg by adding 4 kg for the leg band and 2 kg for the waist band, and 2 kg for the neck band 3.
It is towed with a force of kg.

Assuming that the grip 4 is pulled with a force of 2 kg and this force is equally distributed between the neck band 3 and the lower leg traction rope 1B below the bed, the neck band 3 is 1 kg and the leg band 2 is 2 kg.
, the waist band 6 is pulled with 1 kg, the leg band 2 and the waist band 6 are pulled with 3 kg, and the neck band 3 is pulled with 1 kg.

Figure 3 shows a leg traction rope 1B with a grip 4 connected to one end.
The other end is connected to the leg band 2, and this leg traction rope 1B
A movable pulley 7 on which is hung is connected to a waist band 6.

This pillar traction device pulls the grip 4 with a force of 2 kg, and if this traction force is equally distributed between the neck traction rope 1A and the leg traction rope 1B, the neck band 3 has a force of 1 kg, and the leg band 2 has a force of 1 kg. is pulled by a force of 1 kg, and the waist band 6 is pulled by a force of 2 kg.

Although not shown, it is also possible to connect one end of the leg traction rope to the bed.

In this case, the rotating shaft of the movable pulley is connected to the leg band or waist band with a sub-traction rope.

With this structure, the rotating shaft of the movable pulley is pulled with twice the pulling force of the leg and waist traction ropes, so the leg band or waist band pulls the column with twice the force of the neck band.

In the pillar traction device that is attached to the bed configured as described above, the main traction rope is connected to a grip at one end and consists of a neck traction rope and a leg traction rope, and one end of the neck traction rope is connected to a neck band. At the same time, the leg traction rope is hung on a movable pulley, and the rotating shaft of this movable pulley is connected to either the leg band or the waist band via the sub traction rope. Alternatively, half of the traction force of the waist band will be applied to the leg traction rope, and the traction force of the neck band will be less than half of the traction force of the leg band or waist band connected to the movable pulley.

For this reason, you can pull the pillar with stronger force for a longer period of time without feeling pain or worrying about cheekbone deformation when pulling it.
Comfortable and effective treatment can be achieved.
