Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that in the existing bone orthopedic rehabilitation field, a series of fixed rings must be selected according to the patient's condition, and the size of the fixed rings is difficult to adjust. The size-adjustable combined fixing ring can adjust the size of the fixing ring by adjusting the position of the nut and removing the connecting piece to improve compatibility

Abstract

The invention discloses a size-adjustable combined fixing ring for skeleton rehabilitation external fixation. The size-adjustable combined fixing ring comprises multiple arc parts, sleeve-type connecting pieces and plug-type connecting pieces, each sleeve-type connecting piece comprises an arc connecting end and a linear connecting end which are integrally formed, each plug-type connecting piece comprises an arc connecting piece and a linear connecting piece which are integrally formed, and the arc parts, the sleeve-type connecting pieces and the plug-type connecting pieces are connected in sequence to form the overall combined fixing ring. According to the size-adjustable combined fixing ring, the size of the fixing ring can be adjusted through the mode of adjusting the positions of nutsand removing the connecting pieces, and thus the applicability and compatibility of the combined fixing ring are improved; by connection of all the parts, processing of fixing rings of different sizesis achieved without die change operation during production, the production cost can be significantly reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of orthopedic rehabilitation outside the field, and more specifically relates to a size-adjustable combined fixing ring for external fixation of bone rehabilitation. Background technique [0002] Fixation devices are indispensable in surgical orthopedic treatment. The traditional fixation method generally uses internal fixation with steel plates, and now there is also a treatment method of external fixation with less trauma-Taylor skeleton external fixation. Dr. Taylor connected six telescopic extension rods obliquely to the proximal and distal rings, and they can rotate freely at the connection points. As long as the length of one of the extension rods is adjusted, one ring will change its position relative to the other . The computer program software can be used to calculate the length of the extension rod relative to the deformity parameters, and can imitate any deformity to pre-build a Taylor space frame ...
