Description

A lumbar disc herniation traction frame

technical field

The utility model relates to a lumbar intervertebral disc herniation traction frame capable of simultaneously performing two kinds of physical therapy, which can effectively treat the lumbar intervertebral disc herniation disease, and belongs to the technical field of medical devices.

Background technique

Lumbar intervertebral disc herniation is a common low back disease, which can be caused by many reasons, such as poor sitting and standing posture, long-term bending or heavy physical labor, long-term desk work, often looking down at mobile phones and so on. At present, the methods of treating lumbar disc herniation mainly include drug therapy, physical therapy and surgery. Because of the limitations and risks associated with drug therapy and surgery, people prefer physical therapy.

Physical therapy includes traction and massage. Traction therapy generally requires the patient to lie flat on a traction bed and perform treatment by applying stretching force to the lumbar spine and surrounding muscles. The disadvantage of this therapy is that the traction bed occupies a large area and its use site has great limitations. Tuina is a targeted massage on the lesion site, but the cost of manual massage is high and the curative effect is greatly affected by human factors, so there are certain risks. Using a massage bed for treatment can effectively reduce the cost of treatment and reduce the risk of treatment. However, due to the different heights of different patients, it is generally difficult for the waist massage device installed on the fixed position of the bed to be aligned with the patient's waist, which seriously affects the treatment effect.

Clinical experience shows that the combination therapy of traction and massage can achieve better therapeutic effects, but the existing medical devices for lumbar disc herniation have a single function and can only provide one therapy. To implement combination therapy, only traction can be used alternately. The use of bed and massage bed for treatment not only prolongs the treatment time, reduces the treatment efficiency, but also greatly reduces the efficacy. Therefore, it is very necessary to design a lumbar disc herniation medical device that can perform two kinds of physical therapy at the same time.
