Description

A new type of reduction orthopedic airbag for thoracolumbar fractures

technical field

The invention relates to an orthopedic treatment instrument, in particular to a novel reset orthopedic airbag for thoracolumbar fractures.

Background technique

With the development of the traffic and construction industry, traffic accidents and work-related accidents are increasing. Patients usually suffer from thoracolumbar fractures. There are various methods of reduction and fixation for fractures. The commonly used clinical treatment methods include hyperextension reduction, plaster vest external fixation or surgery. Internal fixation, wherein the patient is treated with hyperextensive reduction and plaster vest external fixation, sometimes has serious complications such as nerve damage; surgical internal fixation, its cost is high, and the patient is traumatized.

Buckling and compression fractures and dislocations are relatively common in clinical practice. If not treated properly, chronic intractable low back pain and back deformities will be left over, which will affect the patient's life and work. Early fracture reduction using external fixation braces for thoracolumbar fractures, restoration of the anatomical height and physiological curvature of the injured vertebral body, restoration of the effective volume of the spinal canal, and reduction of secondary injuries are commonly used treatment methods at present. Because the external fixation brace for thoracolumbar fractures in public use is composed of armpit brackets, fastening screws, upper fixation straps, compression nuts, and lower fixation straps. The hanging method carries out fracture reduction and then puts on the bracket, so it not only has a slow curative effect, but also has many procedures, and its performance is not stable. In addition, the currently used external fixation braces for thoracolumbar fractures often cause skin jams because the screw rods connected by the compression nuts are on the same straight line as the axillary supports.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, provide a method to effectively improve the success rate of reduction in patients with thoracolumbar fractures, effectively restore the physiological height of the spine, effectively reduce the kyphosis of the thoracolumbar spine, and effectively reduce the patient's pain.

The new airbag for reduction and correction of thoracolumbar fractures as described above is characterized in that the outer airbag is composed of a hard material support plate and an outer skin bonded to the support plate.

The novel airbag for reduction and correction of thoracolumbar fractures as described above is characterized in that the outer airbag is an independent airbag.

The new type of reduction orthopedic airbag for thoracolumbar fractures as described above is characterized in that the belts are arranged on the left and right middle waist support, an upper bust belt is provided on the upper part of the middle waist support, and a bottom is provided on the lower part of the middle waist support. Cassette, the drawstring is arranged between the upper bust cuff and the bottom cuff.

The above-mentioned novel reduction orthopedic airbag for thoracolumbar fractures is characterized in that a bust adjustment plate is provided on the upper chest circumference cassette, a convex post is provided on the bust adjustment plate, and a hole is provided on the upper chest circumference cassette. The boss is plugged into the hole so that the bust adjustment plate is fixed on the upper bust tape.

The above-mentioned novel reduction orthopedic airbag for thoracolumbar fractures is characterized in that a belt adjustment device is provided on the middle waist support.

The new airbag for reduction and correction of thoracolumbar fractures as described above is characterized in that the outer airbag is an arc-shaped airbag designed according to the size of the thoracolumbar circumference of a human body.

The new airbag for reduction and correction of thoracolumbar fractures as described above is characterized in that the outer ventilation tube and the inner ventilation tube are respectively provided with one-way control valves.

In summary, the beneficial effects of the present invention: the present invention is provided with an inner airbag in the outer airbag, so that when the internal pressure of the outer airbag is lost, the height of the outer airbag can also be adjusted, effectively improving the recovery of patients with thoracolumbar fractures. success rate, effectively restore the physiological height of the spine, effectively reduce the kyphosis of the thoracolumbar spine, and effectively reduce the clinical complications of patients. The external fixation brace includes a belt, a middle waist support, an upper bust cassette and a bottom cassette. Using the product of the present invention, patients can get out of bed early, reduce hospitalization time, reduce complications, and effectively save government medical resources. The trachea and the internal ventilation tube are respectively provided with one-way ventilation valves, which can effectively prevent gas leakage in the air bag, and patients wearing the product of the invention feel comfortable when using it, and its structure is simple, and the production cost is relatively low.
