Description
Technical Field
The utility model relates to an orthopedics external fixation field especially relates to orthopedics external fixation device of forearm and palm portion of emergency department's bone fracture patient.
Background
The existing orthopedic external fixation material and the method mainly comprise the following steps: plaster fixation, high-molecular bandage fixation, prefabricated mould fixation and inner support fixation.
Plaster bandage fixation and high polymer bandage fixation, if the cast type is used for patients in emergency treatment, the cast type plaster bandage has the defects that the cast type plaster bandage is not suitable for treating complicated parts, is difficult to transmit x rays and cannot be detached; if the bracket is made, dynamic fitting fixation at any time along with the constantly changing swelling of the patient can not be performed, and the patient needs to go to a hospital for correction for many times. When the swelling reaches the limit, the plaster and the polymer bandage can make the joint between the injured limb and the outer fixing sleeve disappear and a cavity between the injured limb and the outer fixing sleeve appears after the edema exudate is absorbed; when edema does not exist or at the early stage, the edema of the injured part of the affected limb is increased by the traditional plaster support or the polymer bandage support, and the affected part is pressed to cause tissue damage and further necrosis. Therefore, the traditional plaster support or the polymer bandage support is fixed, so that the hospital clinically needs to detach the gauze wound on the injured limb of the patient for several times for re-fixing, which may cause the risk of secondary fracture of the patient and damage the tissue to necrosis due to the obstruction of blood transportation caused by untimely treatment.
The prefabricated mould is fixed, and the patient needs to go back and forth for many times to correct, which wastes time and labor.
The fixation of the internal support can cause new bone trauma and infection, and the cost is higher, and the application is increasingly reduced.
In the utility model patent application named "polyurethane for orthopedic external fixation system under complex environment and preparation method thereof" (patent number zl200910052379.x), a novel orthopedic external fixation system composed of the polyurethane for orthopedic external fixation system is disclosed, which can treat the fixation of complex parts which are difficult to treat by gypsum and the tube-shaped fitting fixation of any body surface without swelling of four limbs.
Therefore, it is one of the research directions that those skilled in the art are constantly working on to create a polyurethane orthopedic external fixation system suitable for the limbs of patients with bone injuries in emergency treatment of forearms and palms.
