The utility model relates to a universal locking plate, which comprises a locking plate and a bonding plate. The locking plate and the bonding plate are formed in one body. The bonding plate is provided with an LCP lengthened bonding hole. The locking plate is provided with a guide pin hole and a locking hole, in which the locking hole is a spherical hole. An elastic open sleeve ring is movably arranged in the locking hole, in which the inner wall of the opening sleeve ring is provided with a threaded hole. A limit groove is arranged on the locking plate corresponding to the opening of the jacket ring, and a cylinder is fixed in the limit groove. One end of the column is provided with an external thread and a cover plate. A hollow column is fixed at the bottom of the cover plate, and the inner wall of the hollow column is provided with an internal thread. The hollow column is rotated with the column body to realize the connection between the cover plate and the column body, and is tightly pressed against the open jacket ring through the cover plate at the same time. The outer edge is on the locking plate, so that the opening sleeve ring is fixed in the locking hole. The multi-angle design of this scheme is convenient for clinicians to choose the corresponding angle to fix according to the actual needs, which shortens the operation time and improves the efficiency of the operation.
【技术实现步骤摘要】
一种万向锁定接骨板
本技术涉及医疗器械领域,尤其是一种万向锁定接骨板。
技术介绍
接骨板,是带孔板状骨折内固定器件。临床上常与骨螺钉或接骨丝配合使用,分为普通接骨板和加压接骨板两类,根据不同用途可制成条形、Y形、L形、T形等。目前的接骨板用于骨科内骨折部位的固定,通常的接骨板主要由锁定螺钉和钢板组成,此结构中锁定螺钉与钢板之间的角度都是预先设定好的,锁定孔只有一个方向,由于骨折破损部分的差异,现有的锁定钢板螺钉系统常存在锁定螺钉与钢板之间所设定的植入方向和实际植入方向不一致,大大影响了手术效果,也降低了手术的成功率,目前也有设计一些可以实现螺钉调节角度的结构,此机构存在的问题是其会随着螺钉的转动而转动,导致锁定不牢固的问题发生。
技术实现思路
针对上述问题,本技术提供一种万向锁定接骨板,通过弹性开口套环及限位槽设置,使锁定螺钉可以根据植入方向来进行角度调整,在提高手术效率的同时加强了接骨板的固定。为解决此技术问题,本技术采取以下方案:一种万向锁定接骨板,包括锁定板与结合板,所述锁定板与结合板一体成型,结合板上设有LCP加长结合孔,所述锁定板上设有导针孔与锁定孔,其中锁定孔 ...
