Description
Technical field
This utility model relates to medical field, particularly relates to a kind of Sternum saw for cutting breastbone.
Background technology
In the medical field, owing to having problems in thoracic cavity or needing to treat in thoracic cavity, need breastbone to cut, thoracic cavity is treated.There is chest bone saw product on the market at present, but because present chest bone saw operationally can cause chest bone saw to have slight rocking owing to pulling motor to work back and forth, and owing to carrying out work at inside of human body, sometimes saw cutter is needed to rotate a little, rotation saw cutter can only be carried out by rotating brill rifle when current chest bone saw works, so, can be affected when operator works, cause work mistake.Therefore, when solving chest bone saw work, weak vibrations and saw swivel just seem particularly important to the problem of difficulty.
Utility model content
For above-mentioned prior art Problems existing, the purpose of this utility model is to provide a kind of Sternum saw for cutting breastbone, by padding after pulling motor back to install damping additional, prevent from chest bone saw from operationally producing to rock, and by arranging auxiliary rotary axle, convenient saw swivel moves, and when solving chest bone saw work, weak vibrations and saw swivel are to the problem of difficulty.
This utility model provides a kind of Sternum saw, comprise fuselage and the small of the stock, be provided with in described fuselage and pull motor, described fuselage left end is provided with saw cutter holder, described saw cutter holder is provided with saw cutter, described saw cutter holder is connected to by actuating device and pulls on motor, described pull motor rear end to be provided with damping after pad, after described damping, pad is arranged on and pulls between motor and fuselage right side, described pulling between motor and saw cutter holder is provided with auxiliary rotary axle, described auxiliary rotary axle is arranged on by pin and pulls on motor, the described small of the stock is provided with by compressing switch, machine operation is pulled by pressing on-off control.
Further improvement is: described saw cutter holder is arranged on fuselage by adjustment bolt, described fuselage is provided with at least three installing holes, by the position of adjustment adjustment bolt in installing hole and then the length of adjustment saw cutter holder.
Further improvement is: the described small of the stock is provided with adjustment knob, and described adjustment knob is connected on the small of the stock and fuselage, by adjustment adjustment knob and then the angle between adjustment fuselage and the small of the stock.
Further improvement is: being provided with device for fixing screen on headrest below described auxiliary rotary axle, being fixed on device for fixing screen on headrest by auxiliary rotary axle when without the need to rotating by pin.
The beneficial effects of the utility model are: by padding after pulling motor back to install damping additional, prevent from chest bone saw from operationally producing to rock, avoid causing security incident because chest bone saw operationally rocks, and by arranging auxiliary rotary axle, convenient saw swivel moves, without the need to manually carrying out rotation hand drill, and the convenient position changing saw cutter of adjustment bolt being set, increasing work efficiency.
