Abstract
The utility model relates to a gutta-percha point amputator which is used to amputate a gutta-percha point when a dentist performs a root canal filling operation. The gutta-percha point amputator consists of a plastic front head and an aluminum tube. A copper tube, an electric heating wire, a switch and a copper sheet in the plastic front head are sequentially in electric connection; and the long copper tube and the copper sheet of the plastic front head are connected with a positive electrode and a negative electrode of a dry battery of the aluminum tube. When the switch is on, the electric heating wire is electrified and rapidly gets hot, and the dentist uses the gutta-percha point amputator to scald down the gutta-percha point.
Description
Affiliated technical field
This utility model relates to a kind of cutter that cuts off gutta percha point in the dental root canal filling treatment, especially simply the gutta percha point cutter of fast shut-off gutta percha point.
Background technology
At present, when odontologist cuts off gutta percha point in carrying out root canal filling treatment, generally be will dig with alcohol burner gutta percha point is scalded after the little apparatus heating such as spoon disconnected.This method is time-consuming both, dangerous again property.
Summary of the invention
In order to overcome the drawback that existing gutta percha point cuts off way, this utility model provides a kind of gutta percha point cutter, and this gutta percha point cutter can not only cut off gutta percha point quickly and safely, and can also be after cutting off gutta percha point auto power off.
The technical scheme that its technical problem that solves this utility model adopts is: positive source is electrically connected with switch one end, the switch other end is electrically connected with copper pipe, and copper pipe is electrically connected with heating wire, and heating wire is electrically connected with another copper pipe, this copper pipe is electrically connected with power cathode, forms a complete loop.Heating wire curves the U type.When opening switch, the heating rapidly of heating wire energising back, odontologist just can scald gutta percha point disconnected with it.After 10 seconds, switch is with automatic disconnection, and heating wire recovers room temperature gradually.
The beneficial effects of the utility model are, can cut off gutta percha point quickly and safely, do not need the heating of reuse alcohol burner to dig spoon and wait utensil to scald the gutta percha point that breaks, and are simple in structure, the saving energy, environmental protection more.
