Problems solved by technology

[0003] However, the current sternal closure fixation device cuts the sternum and fixes it with a steel wire or a small number of sternal fixers. Fixing with a steel wire is not only difficult for doctors to operate, but also the steel wire and the sternum often rub against the sternum after fixation, which will affect the closure of the sternum. The current sternal fixation device Nuts and bolts are used to fix and control the overall length, which is not only inefficient to operate, but also has poor fixation, which affects the recovery of the sternum
