The rotating bone nail for orthopaedics comprises a bearing part and a screw, wherein one end of the bearing part is a fixed end, and the other end of the bearing part is a connecting end provided with a connecting groove; one end of the screw is a nail, the other end of the screw is a connecting part combined with the connecting groove of the bearing part; the rotating bone nail is characterized in that the connecting part and the connecting groove are actually combined in a single axle rotation mechanism before an operation, so that the bearing part actually is capable of rotating only around the axle of the nail before the operation.
Description
Technical field
The present invention is relevant a kind of rotating bone nail for orthopaedics, but espespecially a kind of single-shaft-rotation, fixing rotating bone nail for orthopaedics.
Background technology
Generally speaking, vertebra is not in line, and the fixed bar in spinal fixing device is in line, and current settling mode is nothing more than following several structures:
1. use the angled nail of tool, treat the angle of bone fixation internode with counteracting, such as referring to TW-183341, TW-168911 etc.But described structure, must carry out accurate preoperative assessment, also do not allow any deviation in operation, in order to avoid can't be fully or excessively offset the angle for the treatment of the bone fixation internode.
2. use additional secure bond piece, treat the angle of bone fixation internode with counteracting, such as referring to TW-250680, TW-292540 etc.But described structure must additional fixedly combined block, extra unit/assemblies such as support screw cap, takies larger operative space, so that extends operating time and postoperation recovery time.
3. with universal coupling apparatus (universal connecting device), deal with problems, such as US-5,474,551, US-5,507,746, US-5,575,791 etc.; US-5 for example, 474,551st, utilize universal pad fixture (a universal pad fixation device), solve above-mentioned vertebral segments usually and not parallel problem.But described structure is comparatively complicated, operation trouble so that extend operating time concerning the doctor, and because described structure is side locking and can be more for movable joint, poor to the degree of stability of single unit system and all more U-shaped fixed bar of loading that can carry.
4. use two adjusting pad piece fixed structures, treat the angle of bone fixation internode with counteracting, for example, referring to TW-294034.But described structure is only applicable to hone lamella-nail fixed system, can not be for U-shaped bar-fixed bar system.
5. with multi-axial screws (polyaxial screw), deal with problems, such as the U.S. check and approve patent US-5520690, US-5531746 ... 39 of US-71862552, US-7207992 etc., and relevant publication application case US-20010012937, the US-20020111626 of the U.S. ..., US-20070161995, US-20070162006 etc.This is current mainstream technology.Described technology is all to utilize the multiaxis nail to solve above-mentioned vertebral segments usually and not parallel problem basically.Though described multiaxis nail can solve vertebral segments usually and uneven problem easily, but U-shaped bearing section and the degree of stability between this multi-axial screws of this multiaxis nail are inexcellent, therefore, how can solve easily the common also uneven problem of vertebral segments, can make again between the U-shaped bearing section of the screw of nail and nail in conjunction with more stable, be a test in fact.
