Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an orthopedic disease of the neck, that is, a muscle of the neck,
The present invention relates to a cervical vertebra fixing device used for the purpose of suppressing movements of the neck (anterior flexion, dorsiflexion, lateral flexion, rotation) and reducing the weight applied to the cervical spine for the treatment of diseases such as bone and ligament.

[Conventional technology]

The cervical spine fixing device is roughly classified into a color device, a device with a strut, a rigid device, and a halo race. There are various types of collar appliances such as soft materials such as foam to hard materials such as leather, plastic, and metal, but they are appliances that are wrapped around or attached to the neck area. It is an orthosis in which the head is fixed with the occipital bone and is supported on the shoulder with two or more stanchions so that it can be adjusted. The rigid orthosis is made of a hard material between the head supporting part and the trunk fixing part. Is a brace that is height-adjustable like a brace, and a halo race is a brace that supports the skull by fixing the harrow to a trunk brace with a brace. These orthoses are used according to the content of the disease, mainly the former two are mild diseases,
The latter two are indicated for severe illness.

The cervical spine fixing device belonging to the above-mentioned collar device has a length necessary to surround the neck with the foam, polyethylene plate, and polypropylene plate as described above, the mandible to the sternum, the head lower part to the shoulder, and the lower back of the skull. Cut to a sufficient width from the back to the back, attach cushioning material around the collar, collars with male and female coupling materials attached so that both ends can be joined, and the above collar in the width direction on the head side and shoulder side. There is a collar that can be adjusted to suit the length of the neck by separating it into different parts, and the height can be adjusted by changing the bonding position, and it is a composite of polyethylene low foam, high foam and urethane foam with different hardness. The applicant has proposed a color in which a cutting line is printed on the outside of the boomerang type core material of the body so that the height can be adjusted according to the length of the patient's neck (Japanese Patent Publication No. 61- 8893 JP).

In such a conventional cervical spine orthosis belonging to the collar brace, the method of adjusting the width in order to match the length of the patient's neck is to soften the material itself and make it slightly wider, deform the material, and move the body up and down. There have been adopted a method of dividing into two and shifting the connecting position in the vertical direction in the middle to change the width as a whole, and a method of measuring the form and length of the patient's neck and cutting the core material.

However, these methods have problems such as lack of stability and fit, troublesome work, and failure due to excessive cutting.
