There are multiple screwed holes；The side of lower plastron main part is provided with multiple chute buckles；The top surface of lower plastron main part is provided with only
Move back tooth；Upper plastron, locking tooth is provided with lower plastron；One end of lower plastron main part is provided with holding claw；Upper plastron, lower plastron
Side be arc-shaped.
Compared with the existing technology, the features of the present invention and progress are as follows：
1st, it is fixed using sternal bar of the invention, substantially reduce fracture of sternum operating difficulty；
2nd, sternal bar of the invention is used, it is to avoid respiratory movement causes later stage fixture to release etc. to occur, can rapidly recover thorax
Shape, hence it is evident that mitigate pain；
3rd, using sternal bar of the invention, in early days can out-of-bed activity, reduce lung inflammation, the complications such as atelectasis and occur, typically
Patient shortens the hospital stays without using lung ventilator, improves the quality of living, and labour has been recovered to greatest extent；
4th, sternal bar of the invention can be dismantled conveniently；
5th, when sternal bar of the invention is dismantled, sternal bar is removed from breastbone by only need to backing out locking nail, it is convenient rapid；
6th, upper plastron of the invention, locking tooth is provided with lower plastron, it is ensured that cannot be slided after sternal bar locking and strutted；
7th, fixed nail of the invention plays a part of to position and prevents plastron from rocking；
8th, the upper plastron motion of chute buckle limitation of the invention, prevents it from turning up.
