Abstract
A quick release sternum closing fixator has a locking roller, and a male fixing piece and a female fixing piece that can be plugged together. The male fixing piece has an elastic plug and the first claw hook plate. The elastic plug has the first serration on both sides and a tightening groove in the middle, thus forming two elastic claws. A tensioning device forces the two elastic claws to move against each other is provided between the said locking roller and the two elastic claws. After the locking roller rotates, when the elastic claws on the male fixing piece lose resilience due to the growth of human tissues, the two elastic claws can be forcibly pulled back to the initial state by rotating the locking roller, thus smoothly and quickly opening the sternum closing fixator.
