The suprasternal plate is convenient to dismount and capable of achieving secondary application if necessary; the contact surfaces of the upper suprasternal plate / the middle suprasternal plate and the lower suprasternal plate are provided with the locking teeth matched with one another to achieve limiting effects.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a sternum plate. Background technique [0002] After traditional thoracotomy in cardiothoracic surgery, it is necessary to close and fix the sternum, but there are certain disadvantages: the two thoracotomy operations are too long, and the sternal plate is easy to retreat and not locked tightly; when the sternal plate is removed, the wound is easy to be damaged, Prolonged wound healing time; inevitable bone destruction; due to destructive removal, the sternal plate cannot be installed again; prolongs the recovery period of the patient, increases the risk of infection, and indirectly causes lung infection; the operation is complicated and inconvenient ;During the disassembly process of the traditional sternal plate, since the sternal healing needs a certain period, when it needs to be removed after complete healing, there may be tissue and meat around the sternal plate, and the ...

[0002] After traditional thoracotomy in cardiothoracic surgery, it is necessary to close and fix the sternum, but there are certain disadvantages: the two thoracotomy operations are too long, and the sternal plate is easy to retreat and not locked tightly; when the sternal plate is removed, the wound is easy to be damaged, Prolonged wound healing time; inevitable bone destruction; due to destructive removal, the sternal plate cannot be installed again; prolongs the recovery period of the patient, increases the risk of infection, and indirectly causes lung infection; the operation is complicated and inconvenient ;During the disassembly process of the traditional sternal plate, since the sternal healing needs a certain period, when it needs to be removed after complete healing, there may be tissue and meat around the sternal plate, and the surrounding tissue and meat of the sternal plate must be removed first. to cut

In addition, the traditional fixation of the sternum plate is not firm enough, it is prone to loosening, and it will also cause lung inflammation, atelectasis and other complications; after the sternum heals, it needs to be disassembled. The traditional method requires special disassembly tools. Cut the sternal plate to remove the fixed sternal plate
