Abstract
The utility model discloses a kind of molars root canals mouth and open wide brill, comprise work handle, the top of described work handle is provided with draw-in groove, and the below of work handle is provided with working beam, and the below of described working beam connects bores tooth, and the junction of working beam and brill tooth is provided with baffle ring; The end of described brill tooth is provided with smooth seeker, and brill tooth is provided with from top to bottom groove closely gradually, this utility model solves GG in prior art and is drilled in and carries out molars root canals mouth when opening wide preparation, and drilling cuttings is not easily discharged, easily heat production and ineffective drawback in root pipe; Solve GG in prior art be drilled in carry out molars root canals mouth open wide preparation time, overcome and prepare out the bad drawback of root canal orifice form; Solve GG in prior art to be drilled in and to carry out molars root canals mouth when opening wide preparation, overcome at present because drill point is oversize, unhandy drawback in yellow race's population in the Orient, thus overall efficiency is higher.
Description
Technical field
This utility model relates to medical instruments field, and specifically a kind of molars root canals mouth opens wide and bores.
Background technology
The kind of the medical apparatus and instruments that relevant root canal is at present correlated with mainly contains GG and bores and P brill, but all there is shortcoming, Problems existing and reason be lower some: 1, GG bore do not carry out limit preparation depth mechanism design, when preparing root canal orifice, the degree of depth is not easily grasped for abecedarian, be easy to root canal preparation crossed dark or root canal preparation become beaker shape root pipe, be unfavorable for the effect of root canal in the future.2, when GG is drilled in preparation root pipe, its drill bit and drilling rod do not carry out reinforcement design, are easy to rupture.3, the brill tooth that at present GG bores does not carry out the automatic discharge design of drilling cuttings, and the chip that preparation root pipe is very easily caulked bores tooth, reduces work efficiency, and then occurs frictional heat, causes that patient's be not suitable for the adverse consequences that in associated high-temperature root pipe, high temperature produces.4, the form that GG bores at present is fusiform, and root canal orifice unlimited preparation requirement is bell mouth shape, so the tapering boring the root canal orifice prepared out with current GG shows slightly not enough.5, P bores drill point when being mainly used as the preparation of root canal pile road, to a certain extent, can be used for carrying out molars root canals mouth and open wide preparation, but it does not have tapering and preventing to prepare dark device and design original intention itself is preparation for root canal pile road, so, open wide in preparation at root canal orifice, it is poor that its efficiency and root canal orifice molding aspect successful bore than GG.
Summary of the invention
The purpose of this utility model is that providing a kind of molars root canals mouth to open wide bores, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of molars root canals mouth opens wide and bores, and comprise work handle, the top of described work handle is provided with draw-in groove, and the below of work handle is provided with working beam, and the below of described working beam connects bores tooth, and the junction of working beam and brill tooth is provided with baffle ring; The end of described brill tooth is provided with smooth seeker, and bores tooth and be provided with from top to bottom groove closely gradually.
As further program of the utility model: the edge of described baffle ring exceeds the root 0.25mm-0.30mm boring tooth, prevent from preparing deeply, objectively limit drill point and go deep into can not surpassing 3mm in root pipe.
As this utility model further scheme: the length of described brill tooth is 2.5mm-2.6mm, and its tapering is 0.08 tapering.
As this utility model further scheme: described working beam length is 10mm-12mm, the long 13mm-15mm of work handle.
As this utility model further scheme: described smooth seeker is long is 0.5mm-0.6mm, and diameter is 0.5mm-0.6mm, and smooth seeker makes brill tooth in the process entering root pipe, not easily causes the side of root pipe to wear risk.
Compared with prior art, the beneficial effects of the utility model are: this utility model solves GG in prior art and is drilled in and carries out molars root canals mouth when opening wide preparation, and drilling cuttings is not easily discharged, easily heat production and ineffective drawback in root pipe; Solve GG in prior art be drilled in carry out molars root canals mouth open wide preparation time, overcome and prepare out the bad drawback of root canal orifice form; Solve GG in prior art to be drilled in and to carry out molars root canals mouth when opening wide preparation, overcome at present because drill point is oversize, unhandy drawback in yellow race's population in the Orient, thus overall efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of molars root canals mouth of this utility model opens wide brill.
In figure: 1-draw-in groove, 2-work handle, 3-working beam, 4-bore tooth, 5-baffle ring, 6-groove, the smooth seeker of 7-.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of molars root canals mouth opens wide and bores, comprise work handle 2, the top of described work handle 2 is provided with draw-in groove 1, and the below of work handle 2 is provided with working beam 3, the below of described working beam 3 connects bores tooth 4, and working beam 3 is provided with baffle ring 5 with the junction of boring tooth 4; The end of described brill tooth 4 is provided with smooth seeker 7, and bores tooth 4 and be provided with from top to bottom groove 6 closely gradually.
The edge of described baffle ring 5 exceeds the root 0.25mm-0.30mm boring tooth 4, prevents from preparing deeply, objectively limits drill point and go deep into can not surpassing 3mm in root pipe.
The length of described brill tooth 4 is 2.5mm-2.6mm, and its tapering is 0.08 tapering.
Described working beam 3 length is 10mm-12mm, the long 13mm-15mm of work handle 2.
