Invention patent external fixing frame

Patented ankle frame

Wuyan's exclusive product combined three-dimensional orthopedic traction fixator adheres to the technical concept of Ilizarov. It mainly adopts ring structure, with patent protection, simple assembly and convenient needle threading. It is suitable for various operations such as fracture, deformity correction, limb extension and so on.

The multifunctional external fixator for ankle joint is designed and completed jointly with domestic and foreign fixation instrument experts in accordance with the requirements of the research group on standardization of bone setting manipulation combined with external fixator thimble fixation in the treatment of trimalleolar fracture issued by the Chinese Academy of traditional Chinese medicine. Derived from the design concept of external fixator for trimalleolar fracture, it is made of stainless steel and carbon fiber. It has the advantages of light weight, multi-dimensional flexible needle threading and fixation. The utility model is composed of a half ring, a heightening column and a needle locking device. It is the exclusive product of Wuyan company and the first external fixator for trimalleolar fracture at home and abroad. It is suitable for the minimally invasive treatment of joint fractures such as trimalleolar fracture, bimalleolar fracture and Pilon fracture. The operation can be completed without cutting the fracture site or with a small surgical incision. The fracture heals quickly and does not need secondary operation to take out the internal fixation.

The new external fixator is a new method for the treatment of trimalleolar fracture and dislocation. The reduction process includes three parts: overall reduction, local reduction and instrument assisted reduction. The acupuncture and fixation methods include six parts: overall reduction and acupuncture fixation, acupuncture fixation of lower tibiofibular separation, acupuncture fixation of lateral malleolus fracture, acupuncture fixation of posterior malleolus fracture, acupuncture fixation of medial malleolus fracture and acupuncture sequence. 1.
