Skid-proof adjustable thoracolumbosacral orthosis

Abstract

The invention provides a skid-proof adjustable thoracolumbosacral orthosis. A main body is composed of a thoracic plate, a back plate, spina iliace plates and a lumbosacral plate, wherein the thoracicplate is connected with the back plate through firm fixing bands, the spina iliace plates are connected with the lumbosacral plate through a waist belt, and the back plate is connected with the lumbosacral plate through metal plates. Except that the length can be adjusted through a gear device, angle adjustment can be conducted at the coronal position; the thoracic plate is connected with the spina iliace plates through extended supporting rods. The skid-proof adjustable thoracolumbosacral orthosis can be used by a patient who has undergone spine internal fixation, a non-operative patient whosuffers from spinal fracture can use the orthosis in the early stage, and therefore, the patient is prevented from remaining in bed for a long time; evenly, the patient can use the orghosis in the bedridden stage, and through a ligament reduction principle, reduction of fracture can be facilitated.

Description

technical field [0001] The invention relates to an orthopedic external fixation medical device, in particular to an anti-slip adjustable thoracolumbar brace. [0002] technical background [0003] Vertebral fractures are common clinically. No matter whether surgery is performed or not, thoracolumbar braces are usually used in the treatment process. However, the existing thoracolumbar braces have such a problem: those who have not undergone internal fixation usually need to stay in bed for 6- The thoracolumbar brace can only be worn for 8 weeks. During this period, the risk of various bed rest complications rises sharply, and the death rate of patients due to bed rest complications is very high. Insufficient support often occurs during the use of the thoracolumbar brace. Insufficient protection for the fractured vertebra, causing pain in the injured vertebra after bearing weight. [0004] If the treatment effect of traditional thoracolumbar braces can be improved, the treatme...

[0003] Vertebral fractures are common clinically. No matter whether surgery is performed or not, thoracolumbar braces are usually used in the treatment process. However, the existing thoracolumbar braces have such a problem: those who have not undergone internal fixation usually need to stay in bed for 6- The thoracolumbar brace can only be worn for 8 weeks. During this period, the risk of various bed rest complications rises sharply, and the death rate of patients due to bed rest complications is very high. Insufficient support often occurs during the use of the thoracolumbar brace. Insufficient protection of the fractured vertebra, causing pain in the injured vertebra after bearing weight

After searching relevant patent documents, it is found that the Chinese utility model patent with the authorized announcement number CN 203539506U discloses a "rapid expansion type thoracolumbar support", which is improved on the basis of the original invention patent (CN 100553574C). This patent uses front and rear bust fixing plates and waist fixing plates to fix the chest and waist respectively, and then stretches them through the front and rear fixed air pressure rods (hydraulic rods). This design seems to be feasible in theory, but it has two serious defects: First, if you want to achieve the effect of being able to stretch, there must be enough friction between the inner layer of the fixing plate and the human body. How this device is realized is not explained. If it is realized by pressurization, it needs How much strength? Can a patient with a fracture bear this kind of strength? Second, how does the patient's breathing proceed after the front and back bust fixation plates and waist circumference fixation plates are pressurized? We know that there are two breathing modes of the human body: chest breathing and abdominal breathing. When one of the modes is restricted, the other mode can be used to compensate. However, if the chest and abdomen are compressed at the same time, breathing difficulties will inevitably occur. Therefore, this design is completely impractical and cannot be used clinically.
