Description

 Cervical traction device {A traction apparatus for the cervical vertebrae}

The present invention relates to a cervical traction device, and more particularly to a cervical traction device capable of effectively pulling only the cervical vertebral portion of the patient without an obstacle, and the patient himself can control the power to exercise the extension.

Cervical vertebrae are the vertebrae at the top of the spine and the neck (specifically, the cervix) of the human body, consisting of seven vertebrae that have different anatomical structures than the lumbar and thoracic vertebrae. There is a rotational movement and flexion and extension movements are able to work smoothly.

As described above, the cervical vertebrae located in the neck are not only much smaller than the back and waist but also have a wider range of motion and more frequent movement than the waist, so they are more susceptible to shock than the back or waist. many.

Cervical spine pains include cervical sprains, cervical disc herniation, cervical fractures, cervical spinal canal stenosis, posterior ligamentosclerosis, and spinal tumors. to be.

The cervical sprain, whiplash injury, the muscles or ligaments around the support for the cervical spine is abnormally tensioned or relaxed, or the cervical spine is overextended due to external force, overflex (過 屈曲), The muscles and ligaments surrounding the neck and cervical spine are stretched or torn and swollen and painful when torsional or squeezed. They are common in car collisions and can also occur during falls and sports injuries.

The ruptured cervical disk (頸椎 椎間 板 脫出 목, ruptured cervical disk), also known as the neck disk, is caused by the degenerative change of the intervertebral disc, soft discs (soft disc) that usually stimulates the nerve by protruding intervertebral discs between the cervical spine ) And two types of hard discs that grow in the back of the cervical spine and stimulate the nerves.

Cervical intervertebral hernia may be caused by trauma or chronic stimulation. After middle age, the cervical intervertebral disc may easily develop after aging and change, and in acute cases, it may occur when reading or watching TV for a long time in a distorted position. It can also appear if you use your computer in a stationary position for long periods of time or if you sleep on a pillow that is too high.

The cervical sprain and cervical intervertebral disc herniation, by physically pulling the cervix, can relax the muscles of the stiff or relaxed muscles and ligaments and stretch between the narrowed cervical intervertebral discs to alleviate the symptoms.

The cervical traction is being performed as a physical treatment of cervical pain.

Conventionally, the cervical traction mechanism for performing cervical traction as described above, (1) a fixed traction mechanism for fixing by pushing the entire neck and shoulders including the chin and the back of the neck to a certain height with screws, and (2) the patient's body Motorized traction mechanism that pulls the back of the jaw and neck with power by using a motor while the pad is fixed to the bed, and (3) Wraps the neck area including the back of the jaw and neck with an air tube and uses the pump to cover the air tube. A pneumatic traction mechanism for pushing up and pulling the neck by expanding it in the longitudinal direction of the neck, and (4) a traction mechanism for fixing the jaw and the back of the neck and hanging it on an iron rod to extend the neck using the weight of the patient.

However, as described above, conventional cervical traction devices are designed to pull the cervical spine by pushing or pulling the jaw and the back of the neck together, so that both the jaw and the back of the neck are pulled because the cervical spine is located at the back of the neck. When the back of the neck is towed only when the short distance of the cervical spine is not only able to effectively pull the cervical spine, the physical pressure is applied to the jaw was a serious problem that can cause TMJ disorders.

For reference, the Temporal Mandibular Joint (TMJ) is a joint located in front of the ear that connects the lower jaw (mandible) to the head (skull) and the muscles involved in the movement of opening and closing the mouth and chewing food. Disorders that occur when TMJ and muscles are not properly positioned and move harmoniously are called TMJ disorders, which can be easily caused by excessive shock or pressure on the jaw.

In addition, as described above, the conventional cervical traction device is inconvenient to use because it must be helped by people around you to exercise the extension after wearing, it is difficult to exercise effectively because the patient does not adjust the traction force when towing the cervical spine In addition, there was a problem that can damage the cervical spine.
