Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to an auxiliary fixing exoskeleton for wearable imaging evaluation.
Background
With the advent of the aging society, the incidence of senile knee osteoarthritis has been increasing. Knee osteoarthritis is a common clinical orthopedic disease, the quality of life of patients is seriously affected by the disease progression to the end stage, only single compartment affected patients account for about 1/3 of the total number, and lesions are mostly affected in the medial compartments. For knee osteoarthritis patients with single compartment involvement, the unicondylar replacement gradually replaces the traditional total knee replacement and tibia high-level osteotomy by virtue of the advantages of small trauma, rapid postoperative recovery and no damage to other knee structures, and when in imaging examination, a doctor is usually required to assist the patient in making the knee joint to turn inwards or outwards, and the imaging is continued until the end, and for patients with severe joint pain and incapable of standing, the doctor is required to support the patient to take the lower limb weight bearing position slice. With the method, a doctor is injured by rays, whether the angle of the knee joint inversion and the angle of the knee joint inversion are consistent or not is difficult to ensure during each shooting, and the repeatability and the reliability of the imaging data are affected by the personal experience operation of the doctor.
Chinese patent document CN209847211U (patent 1) discloses a knee joint varus-valgus stress position bracket for a single leg, which moves the same side lower leg to perform knee joint varus-valgus action by fixing the affected side thigh; chinese patent document CN211325119U (patent 2) discloses a knee varus device, which fixes the thigh and the calf, sets an adjustable varus part and valgus part between the two fixing parts, and realizes the valgus of the knee joint by adjusting the extension of the varus part or the valgus part; chinese patent document CN209847212U (patent 3) discloses a leg knee varus stress position support, which moves the leg to perform knee varus motion by fixing the thigh at both sides; chinese patent document CN211325120U (patent 4) discloses an auxiliary fixing device for knee varus or valgus stress position radiography, which moves a device to a corresponding position by placing two devices with bayonets at the ankle joint and the knee joint of a patient, thereby making the knee joint perform valgus action. Chinese patent document CN215914662U (patent 5) discloses an auxiliary fixation brace for preoperative unicondylar replacement imaging evaluation, which pushes the knee joint of the patient to keep the varus-valgus action through the auxiliary fixation brace; chinese patent document CN113712586a (patent 6) discloses an auxiliary fixing brace for imaging evaluation, which fixes a patient limb through a plurality of side plates, and then pushes the patient knee joint to varus or valgus by means of a joint driving member so as to achieve a stress position. The various solutions presented in the 6 patents mentioned above all present various problems, which need to be further perfected. For example, the devices provided in patent 1, patent 3 and patent 6 are bulky and require to be placed on the examination bed in advance, making the examination process cumbersome; the device provided by the patent 4 has no related metering device, and the error is larger in the placing process; the devices provided in patent 2 and patent 5 are complex in structure and complex in operation. In addition, the design of the 6 patents is not in accordance with the design of human mechanics, and the comfort level is not high in the use process, so that the medical experience of a patient can be reduced, and unnecessary doctor-patient contradiction can be caused; for patients incapable of standing with severe arthralgia, the auxiliary standing function cannot be provided, when the lower limb weight-bearing position piece is shot, secondary injury caused by falling of the patient still needs to be carried out under the assistance of doctors, and the angle of the gonal varus or the gonal valgus cannot be directly judged when the lower limb weight-bearing position piece is shot.
