Modeling mechanism of spine correction treatment equipment

Abstract

The invention discloses a modeling mechanism of spine correction treatment equipment. The first sliding table and the second sliding table are installed on the left side and the right side of the fastening frame correspondingly and can slide up and down, and the electric push rod set is clamped through the swing frame and the pressing plate. A first worm gear rod, a first swing rod, a second worm gear rod and a second swing rod participate in two parallelogram structures to form the electric push rod set, and a third motor and a fifth motor can drive the electric push rod set to swing through a first worm and a third worm. The second worm and the third rack form worm and rack transmission, the fourth worm and the second rack form worm and rack transmission, the fourth motor can drive the second worm to rotate through the first synchronous belt, and the sixth motor can drive the fourth worm to rotate through the second synchronous belt. Therefore, the modeling mechanism can slide up and down and be positioned on the correction frame mechanism through the fourth motor and the sixth motor; the modeling mechanism can enable the lattice structure to form a new lattice model according to a corrected spine three-dimensional model of a patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a modeling mechanism of spinal correction treatment equipment. Background technique [0002] Spondylolisthesis is an orthopedic disease that is difficult to cure quickly. The most common symptom is abnormal kyphosis of the thoracic spine, commonly known as hunchback. The most common type of hunchback is active hunchback that can be corrected. Active hunchback mainly includes long-term sitting posture Postural kyphosis caused by bad posture, paralytic kyphosis caused by trunk muscle weakness caused by disease, and compensatory kyphosis secondary to excessive lumbar lordosis; kyphosis not only damages the appearance of the human body, but also brings a lot of inconvenience to daily life. [0003] The main position of the hunchback is that the spine between the abdomen and the chest has been curved or deeply curved for a long time, which is also the main reason for the high incide...

AI Technical Summary

Problems solved by technology

The above solution has the following problems: in actual use, people who sit on a chair for a long time need to move their bodies unconsciously, and at this time, the imbalance of the table legs is also prone to occur, which brings inconvenience to normal use and has certain limitations. sex

The above scheme has the following problems: ①The user can only operate while standing, and the hunchback patient itself has an abnormal curvature of the spine, which reduces the ability of the lumbar spine to support the body, and standing for a long time will make the patient exhausted during the correction process; The slot can slide on the slide bar and the leaning plate can also be flipped relative to the sliding bar, which leads to the fact that during use, the user’s pressure center on the leaning plate must be on the sliding bar, and the operation is too difficult, otherwise the leaning plate will It will slide relative to the slide bar and turn backwards, causing the patient to fall backwards and cause personal injury; ③The human spine has normal physiological curvature, and the backboard is a flat structure, and the patient will stick his back to the backboard for a long time On the contrary, the spine cannot be corrected correctly, and even overcorrection may occur; ④The positions of the four pressure touch points are fixed, but the height and shape of the patients are different, and young people with smaller bodies cannot trigger the four pressure touch points at the same time. point, so that the orthodontic device has a large audience limitation
