Sleeve-in fixed-angle-type supporting frame assembly push and press fixator based on shrinking and expanding type

Abstract

The invention relates to a sleeve-in fixed-angle-type supporting frame assembly push and press fixator based on a shrinking and expanding type. Through the unique design of the structures and the connecting relationship of a pipe body with two blunt ends, an upper side pressurization supporting frame and a lower side pressurization supporting frame in the sleeve-in fixed-angle-type supporting frame assembly push and press fixator based on the shrinking and expanding type, the problems that shrinking and expansion of a fracture fixing device can not be controlled efficiently and intelligently, the fixing device of the bone can not be stabilized accurately and adjusted accurately at a fixed angle, operation is complex, detachment is not easy, the cost is high, and the fracture postoperative recovery period is long are resolved, the orthopedic injury can be fixed elastically, intelligently, accurately and adjustably, and the sleeve-in fixed-angle-type supporting frame assembly push and press fixator based on the shrinking and expanding type has the advantages of being small in wound, short in operation time, fast in postoperative recovery, easy and convenient to operate and the like.

Description

Technical field [0001] The invention relates to the technical field of fracture fixation, in particular to a fixed-angle fracture support combined push fixer, and more specifically to a shrink-and-expansion-based nested fixed-angle fracture support combined push fixer. Background technique [0002] At this stage, in the treatment of orthopedic injuries, fixation is an important part of it, so it has received great attention, and continuous technical improvements are being made to achieve better treatment results. In the course of clinical treatment, it was discovered that the current fixation of tibiofibular separation and shoulder dislocation has certain defects, and it is necessary to improve. [0003] The lower tibiofibular joint is composed of three parts: syndesmosis, folds, and bone connection. The structure of the lower tibiofibular joint is firm and flexible, and is an important stable structure to ensure the normal movement of the ankle joint. Separation of the lower tibi...

Problems solved by technology

[0018] The purpose of the present invention is to address the deficiencies of the prior art in the related technical field of fracture fixation. On the basis of a large number of existing documents and the inventor's long-term practice, the fixed-angle fracture bracket based on the contraction-expansion type is combined to push the fixator. The unique design of the structure and connection relationship of the tube body with blunt ends at both ends, the upper side pressure bracket and the lower side pressure bracket overcomes the inability of the existing technology to effectively intelligently control the shrinkage and expansion of the fracture fixation device, and the inability to be accurate and stable. Accurate and adjustable angle-fixed bone fixation position, complex operation, difficult disassembly, high cost, slow recovery period after fracture surgery, etc., realize elastic, intelligent, precise, adjustable fixation for orthopedic injuries, and trauma Small size, short operation time, fast postoperative recovery, simple and convenient operation and other beneficial effects
