Description
Technical Field
The invention relates to the technical field of medical auxiliary instruments, in particular to an auxiliary fixing brace for imaging evaluation.
Background
Knee joint unicondylar joint replacement is a treatment means for treating the medial and lateral ankles of the knee joint between knee joint osteotomy and total knee joint replacement; that is, when one of the three compartments, i.e., the medial compartment, the lateral compartment, and the patellar compartment included in the knee joint is diseased, the diseased compartment is replaced. Compared with osteotomy, the knee joint unicondylar joint replacement has the characteristics of high success rate, less complication and quick rehabilitation, and long-term results are superior to that of osteotomy. Compared with total knee joint replacement, the method has the advantages of small operation, retention of posterior cruciate ligament, much bone mass retention, less bleeding and quick rehabilitation.
The selection requirement of the unicondylar joint replacement on the indications is particularly strict, the legs of a patient need to be photographed by X-rays before the unicondylar joint replacement is performed, the soft thighs of the joint compartments are observed, and the indications are selected; when taking X-ray photography, the femur of a patient needs to be fixed, then the knee joint is turned inwards or outwards to a stress position with force, the cartilage joint gap of the patient is exposed, and only then, a doctor can observe the cartilage joint on the photographed X-ray film and make a selection on an indication.
It is now common practice for a doctor to wear protective gloves, wear a lead garment, use the force of the arm to invert or evert the knee joint, and then expose it to radiation. However, this method exposes the physician to radiation, and even with the protection, the frequent exposure still has adverse effects on the health of the physician.
Chinese patent document CN209847211U discloses a knee joint internal and external turning stress position bracket for a single leg, which turns the knee joint inwards and outwards by means of constraining thighs and pushing shanks to swing left and right; chinese patent document CN209847212U discloses a two-legged knee joint internal-external-turning stress position support, which performs internal-external turning on the knee joint by fixing two thighs and pushing two shanks to swing inwards or outwards; chinese patent document CN210019388U discloses a three-point bending thrust apparatus for acquiring X-ray images of knee joints, which performs inward and outward turning of the knee joints by limiting the thighs and calves from one side and pushing the knee joints from the other side; chinese patent document CN211325199U discloses a knee joint varus-valgus device, which sets a telescopic varus portion and valgus portion between a thigh fixing portion for fixing a thigh and a shank fixing portion for fixing a shank, and realizes the varus-valgus of the knee joint by extending the varus portion or the valgus portion; chinese patent document CN211325120U discloses a knee joint varus or valgus stress position X-ray photography auxiliary fixing device, which realizes the varus and valgus of the knee joint by arranging a plurality of cushions with fixing bayonets and arranging the cushions in a staggered manner. The various solutions provided in the above patent documents basically operate the straight leg, that is, after the leg is straightened, the thigh is fixed, and the lower leg is pushed to swing relative to the thigh, so as to realize the varus and valgus of the knee joint position; however, for determining whether the unicondylar joint replacement can be performed, the image obtained by performing the knee joint varus and valgus in the straight leg state cannot be used, but the thigh and the calf are firstly included at an angle of about 150 degrees to 170 degrees, and then the knee joint is turned inwards and outwards, so that the three positions of the medial compartment, the lateral compartment and the patellar compartment can be clearly shot to the maximum extent, and whether the knee joint unicondylar joint replacement is suitable or not can be accurately determined.
