Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect that the knee joint valgus device in the prior art cannot perform stress-position valgus and valgus on the knee joint with the large and small legs flexed into a specific angle, and artificial assistance will cause radiation damage to the human body. , so as to provide a fixed brace that can perform stress-level varus and varus on the knee joint that flexes the large and small legs to a specific angle

Embodiment

[0072] This embodiment provides an auxiliary fixation brace, such as figure 1 As shown, it includes: a side limiting part 1, a fixed connection part 2, a pressing installation part 3 and a joint driving part 4.

[0073] Wherein, the side limiting parts 1 are arranged in pairs, and have a first side plate 11 and a second side plate 12 connected at the ends; there are two fixed connecting parts 2, which are respectively used for fixedly connecting the two first side plates 11 and the second side plate 12. The two second side plates 12 keep the two first side plates 11 and the two second side plates 12 parallel to each other; there are two pairs of pressing mounting parts 3, which are respectively installed on the two first side plates 11 and the two second side plates 12. On the second side plate 12 ; there is at least one joint driver 4 installed at the position where the first side plate 11 and the second side plate 12 are connected to each other.

Abstract

The invention provides an auxiliary fixing brace for preoperative unicompartmental knee arthroplasty imaging evaluation. The auxiliary fixing brace comprises a lateral limiting pieces, fixing connecting pieces, abutting installation pieces and a joint driving piece, wherein the lateral limiting pieces are arranged in pairs and are respectively provided with first side plate and a second side plate, and the first side plate and the second side plate are connected together and are arranged on two sides of the thighbone and the tibia of the legs of a patient respectively to keep the legs of the patient at a certain angle; two fixed connecting pieces are respectively connected with the two first side plates or the two second side plates, so that the two first side plates or the two second side plates are parallel to each other; two pairs of abutting installation pieces are respectively installed on the two first side plates and the two second side plates; and at least one joint driving piece is mounted at the position where each first side plate is connected with each second side plate. According to the auxiliary fixing brace disclosed by the invention, the knee joint of the patient can be pushed to be kept to be inwards turned or outwards turned, X-ray shooting is carried out, manual keeping of a doctor is not needed any more, and the doctor does not need to be exposed in a ray environment so as to be safer.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary devices, in particular to an auxiliary fixation brace used for imaging evaluation of preoperative unicondylar replacement. Background technique [0002] Unicondylar arthroplasty of the knee joint is a treatment method between knee osteotomy and total knee replacement for the treatment of the medial and lateral malleolus of the knee joint; When one of the three compartments, the patellar compartment and the patellar compartment, is diseased, the affected compartment is replaced. Compared with osteotomy, unicompartmental knee arthroplasty has higher success rate, fewer complications, faster recovery, and better long-term results than osteotomy. Compared with total knee arthroplasty, it has the advantages of small operation, preservation of posterior cruciate ligament, more bone mass preservation, less bleeding and faster recovery. [0003] Unicondylar arthroplasty has very strict require...
