A Liftable Fulcrum Device for Scoliosis Flexibility Evaluation

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a liftable fulcrum device for evaluating the flexibility of scoliosis. the

Background technique

Scoliosis is a common spinal deformity that often occurs in adolescents. If it is not diagnosed and treated in time, the degree of scoliosis will continue to progress and aggravate with the physical development of adolescents, and even lead to serious body imbalance, which will not only affect the appearance of the patient , It will also cause serious damage to the patient's mental health and cardiopulmonary function. For severe scoliosis, surgery is the only effective treatment. The preoperative flexibility evaluation of scoliosis is a very important part of the preoperative preparation process of scoliosis. It is very important for judging the structural characteristics of scoliosis, understanding the degree of flexibility of scoliosis, predicting surgical results, selecting surgical fusion segments and surgical procedures. Access, etc. are of great significance. The existing flexibility assessment methods mostly rely on the patient's active cooperation, have poor repeatability, and are not accurate in predicting the postoperative angle. Although the traditional fulcrum device has improved the above shortcomings, its range and measurement accuracy need to be improved, lack of specific quantification standards, and there are certain errors for scoliosis patients of different heights and shapes, so the research and development can be Standardized measurements and more accurate flexibility assessment devices have important clinical significance and practical value for accurately assessing the flexibility of scoliosis and providing scientific guidance for the formulation of surgical plans. the

The distance between them is to adjust the height of the lifting cover 2; the power interface 7 is located on one side of the box body 1. the

In the present invention, the lifting cover 2 is arc-shaped, and its surface is covered with a thin layer of flexible material. the

The use method of the present invention is as follows: the liftable fulcrum device is placed on the examination bed, the examinee lies on the side on the device, and the convex side of the scoliosis faces the device through the pre-evaluation of appearance or imaging. Use the crank handle to pass the transmission screw in the box to lift the lifting cover to adjust the height of the whole device, so that when scoliosis patients of different heights and shapes lie on the side of the device, the pelvis and shoulders can be better lifted off the table . Place the pre-evaluated apex of the scoliosis accurately above the arc apex of the fulcrum device (the thoracic scoliosis is the rib corresponding to the apex). When the fulcrum reaches a certain height, the pressure value will no longer change, and the pressure will be obtained from the pressure display value. At the same time, an X-ray machine is used to take anteroposterior photos to understand the changes in the angle of scoliosis. the

The beneficial effect of the present invention is that: the present invention is mainly used for evaluating the preoperative flexibility of scoliosis patients. Its main advantage is that it provides a repeatable, accurate and quantifiable flexibility evaluation device. The device is suitable for patients of different heights and shapes through the ingenious liftable fulcrum design. At the same time, the baroreceptor and the pressure display enable the device to more accurately display the pressure change value when the scoliosis angle changes, so as to understand the orthopedic force required to achieve the angle change. It not only provides an objective and standardized method for clinical understanding of scoliosis flexibility, but also provides reliable reference information for the formulation of surgical strategies. The invention has novel conception, convenient processing and strong practicability. the
