Description

Distal radius fracture wrist fixation brace

technical field

The invention relates to an external fixation protector for distal radius fractures, belonging to the technical field of external fixation medical devices.

Background technique

Distal radius fractures are extremely common clinically. At present, doctors will perform plaster external fixation on patients after traditional manual reduction. Plaster external fixation has the following disadvantages: 1. After the bone injury, the plaster is applied early, and the edema and hematoma have not yet floated up. As the swelling slowly rises, blisters may form, and if they rupture, ulceration and infection may occur; 2. 1. Swelling after bone injury, swelling does not subside, such as plaster fixation, as the swelling subsides slowly, there is space in the plaster, and the plaster cannot actually fix the patient's wrist; 3. Plaster is applied After that, it is difficult to observe the condition of the patient's wrist, and it is impossible to treat some physical factors on the wrist fracture. Moreover, some patients need to return to the functional position for fixation when the fracture has healed to a certain stage, which requires removing the plaster and performing plaster fixation again, which is very troublesome to operate. In view of the above-mentioned shortcoming of plaster fixation, there is an urgent need for an external fixation protective device that is easy to wear clinically. It is easy to observe the condition of the patient's wrist; it is convenient to adjust the tension of the fixation according to the swelling of the patient's wrist; it is convenient to adjust the posture of the wrist fixation;

Secondly, for distal radius fractures, in order to prevent muscle atrophy and loss of upper limb motor function caused by long-term inactivity of the upper limb joints during the fracture healing process, it is necessary to intervene in some upper limb rehabilitation training for patients from the initial stage of fracture healing. At present, the effect of manual rehabilitation training is good, but due to the high labor cost and the shortage of rehabilitation physician resources, many patients cannot obtain good rehabilitation training. Therefore, there is an urgent need for an intelligent wrist external fixation device to assist and supervise patients to carry out independent rehabilitation training at home.

The protector provided by the invention replaces gypsum to provide external fixation for patients with distal radius fractures, and can assist patients in rehabilitation training.

Beneficial effect: compared with the prior art, the present invention has the following advantages:

(1), at present, for external fixation of distal radius fractures, plaster fixation is almost all selected. The plaster fixation is not easy to disassemble, and its fully wrapped method makes it difficult for doctors to observe the condition of the patient's wrist after surgery. In addition to providing stable external fixation for the patient's wrist like a plaster fixation, the wrist fixation brace for distal radius fracture is also easy to wear, and the patient's wrist part can be observed for hematoma and edema at the hollowed out part, so as to avoid rupture after the formation of blisters ulceration and infection;

(2) Swelling is formed after the bone injury, and the swelling does not subside. If it is fixed with plaster, as the swelling subsides slowly, there will be voids in the plaster. In fact, the plaster cannot play a role in fixing the patient's wrist. The feature of the present invention, which is easy to wear and adjust, allows the doctor to conveniently adjust the fixed tension according to the swelling of the patient's wrist;

(3), plaster fixation and the external fixation protective gear that has on the market can only allow the patient's wrist to be fixed in a certain posture, and cannot be adjusted. However, the present invention can conveniently adjust the fixed posture of the wrist according to the different stages of distal radius fracture healing. In addition, the present invention can also facilitate rehabilitation training for patients after releasing the restriction on the movement of the two degrees of freedom of the wrist;

(4), gypsum fixation and the external fixation protective gear that has on the market now all wrap up the patient's wrist part completely, so some physical factor treatments that are beneficial to fracture healing will not be able to carry out. The present invention can expose the lower part of the patient's wrist fracture, so that it is convenient for the doctor to treat the patient with some physical factors during the fracture healing period;
