Background technique

Brown's traction frame is a commonly used medical auxiliary equipment in orthopedics, mainly used for traction surgery. The Brown's traction frame pulley performs bone traction or skin traction to achieve the purpose of repairing fractures and dislocations, maintaining the position after reduction, correcting joint deformities, and relieving muscle spasm and pain.

However, there are still some problems with the existing Brown's traction frame. The existing Brown's traction frame for orthopedics is composed of a bracket and a pulley, because the bracket is fixed, and the length of each patient's lower limbs, especially the length of the thigh, is different. Similarly, in clinical practice, the length of the traditional Brown-type traction frame roughly corresponds to the patient's calf and thigh and cannot be adjusted, making it unsuitable for patients of different heights. If the same size frame is used, it is not conducive to treatment. Nowadays, it is mostly used to make Multiple Brown's traction frames of different sizes are used to meet the treatment needs of patients of different heights. However, due to the large difference in height between each patient, an excessive number of traction frames are required, and this method has a greater limitations.

Detailed ways

After the applicant's research and analysis, the reason for this problem (due to the large difference in height between each patient, so too many traction frames are needed, and this method has great limitations) is that the current Some orthopedic Brown's traction frames are composed of brackets and pulleys. Because the brackets are fixed, the length of each patient's lower limbs, especially the length of the thigh, is different. In clinical practice, the traditional Brown's traction frame The length of the part roughly corresponding to the patient's calf and thigh cannot be adjusted, and it cannot be applied to patients of different heights. If the same size bracket is used, it is not conducive to treatment. Nowadays, multiple Brown's traction frames of different sizes are made to meet different heights. The treatment needs of patients, but due to the large difference in height between each patient, the number of traction frames required is too much. In order to provide an adjustable Brown-type traction frame, the device is equipped with multiple traction frames. An adjustable mechanism, which includes a lifting unit, a first adjustment unit and a second adjustment unit. Through the cooperation between the above three mechanisms, not only the overall height of the traction frame can be adjusted, but also the length of the traction frame can be adjusted. Furthermore, the orthopedic surgeon can adjust the size of the traction frame according to the patient's height, so only one traction frame is needed to meet the treatment needs of patients of different heights.
