Abstract

The invention provides a novel breastbone saw. The novel breastbone saw comprises a saw body and a pistol grip, a pull motor is arranged in the saw body, a saw blade clip is arranged at the left end of the saw body, a saw blade is arranged on the saw blade clip which is connected with the pull motor through a transmission device, a rear damping pad is arranged at the rear end of the pull motor, the rear damping pad is arranged between the pull motor and the right end face of the saw body, an auxiliary rotating shaft is arranged between the pull motor and the saw blade clip, the auxiliary rotating shaft is installed on the pull motor through a pin, the pistol grip is provided with a push switch, and the pull motor is controlled through the push switch to work. The rear damping pad is additionally installed on the back of the pull motor, so that the breastbone saw is prevented from shaking when working, and safety accidents caused by shaking of the breastbone saw in the working process are avoided; the auxiliary rotating shaft is arranged, so that rotation of the saw blade is facilitated, and a hand drill does not need to be rotated manually; an adjusting bolt is arranged, the position of the saw blade is convenient to change, and working efficiency is improved.

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 ...
