Description

technical field [0001] The invention relates to the medical field, in particular to a novel sternum saw for sawing the sternum. Background technique [0002] In the medical field, due to problems in the chest cavity or the need for treatment within the chest cavity, the sternum needs to be sawed open to treat the chest cavity. At present, there are sternum saw products on the market, but because the current sternum saws are working due to pulling the motor back and forth, the sternum saws will shake slightly, and because they work inside the human body, sometimes it is necessary to turn the saw blade slightly. When the current sternum saw is working, the saw blade can only be rotated by rotating the drilling gun, so the operator will be affected when working, resulting in work errors. Therefore, it is particularly important to solve the problems of slightly shaking and saw blade turning difficult when the sternum saw is working. Contents of the invention [0003] Aiming ...
