Description

Supporting mechanism of intelligence backbone levelling machine

Technical Field

The invention relates to the field of medical instruments, in particular to a supporting mechanism of an intelligent spinal straightening machine.

Background

The spine curvature disease is an orthopedic disease which is difficult to quickly and radically cure, wherein the most common symptom is abnormal posterior protrusion of a thoracic vertebra and is commonly called hunchback, the most common active hunchback in the hunchback is correctable, and the active hunchback mainly comprises posture type hunchback caused by poor sitting posture for a long time, paralytic hunchback caused by weakness of trunk muscles caused by diseases and compensatory hunchback caused by excessive lumbar vertebra protrusion; the humpback not only damages the human body, but also brings much inconvenience to daily life.

The main part of the kyphosis lies in the long-term bending or deep bending of the vertebra between the abdomen and the chest, which is also the main reason of the high incidence of myopia in teenagers, and the kyphosis degree is increased if the slight kyphosis in the young state is not corrected in time, and the kyphosis is difficult to recover along with the increase of the age. Related products such as back posture correction are disclosed in patents CN206961296U, CN206414375U, and CN304114646S, which have a function of correcting the spine to some extent, but the armpits of the user are often uncomfortable to press by elastic objects, so that the user is difficult to wear for a long time.

The invention patent with publication number CN103300620B discloses an anti-humpback seat, which is characterized in that an upper half leg and a lower half leg can be translated in a direction close to vertical direction, a sitting posture sensing unit is positioned on a seat back and used for sensing the pressure of a person on the seat back, a locking device is used for locking a first rack and a first gear, a tightening device is connected with the sitting posture sensing unit, and when the sitting posture is not correct, a prompt can be sent. The above scheme has the following problems: in practical use, people sitting on the chair for a long time need or can move the body unconsciously, and the unbalance of the table legs is easy to occur at the moment, so that inconvenience is brought to normal use, and certain limitation exists.

The invention patent with publication number CN111514529B discloses a using method of an orthopedic medical correction device, which comprises the following steps: backup plate, handle, four pressure sensor, backup plate provide the support for user's back, and two handles supply the user to grip, and whether four pressure sensor monitor head, shoulder and buttock respectively compress tightly the backup plate. The above scheme has the following problems: firstly, a user can only stand to operate, the lumbar vertebra supporting capacity of a humpback patient is reduced due to abnormal bending of the spine, and the patient can be fatigued in the correction process due to long-time standing posture; the abdicating groove can slide on the sliding rod and the backup plate can also turn over relative to the sliding rod, so that a user has to put the pressure center of the backup plate on the sliding rod in the using process, the operation difficulty is too high, otherwise, the backup plate can slide relative to the sliding rod and turn over backwards, and the patient falls backwards to cause personal injury; the spine of a patient is in normal physiological curvature, the back plate is in a plane structure, and the back of the patient is attached to the back plate for a long time, so that the spine cannot be corrected correctly, and even the spine cannot be corrected excessively; the four pressure contacts are fixed in position, the heights and the body types of patients are different, and teenagers with small body types cannot trigger the four pressure contacts at the same time, so that the correction device has large audience limitation.
