Description
Technical field
This utility model relates to the design field of medical apparatus and instruments, particularly relates to a kind of hand rotary apparatus for dentistry prong.
Background technology
Tooth is the organ of our laboratory rodent chow, generally speaking tooth is white yellowish, tooth quality is hard, the various shapes of tooth are applicable to multiple use, comprise and tearing, grate foods, if but we do not note protecting tooth at ordinary times, gingival hemorrhage will be caused, the diseases such as acute-chronic pulpitis, light then hurt like hell, heavy then tooth takes off or pulls out tooth, but generally we can not select to pull out tooth, but can select to remove the dental pulp inside teeth roots root pipe and neural blood vessel, retain other, then fill with medicine or stamp outside steel nail and tumble in ceramic tooth, but remove dental pulp and neurovascular time be all to be pinched prong to rotate remove dental pulp inside tooth and neural blood vessel with hands by doctor, if the innermost tooth in oral cavity is sick, need to remove dental pulp and neural blood vessel for just relatively difficulty doctor, if use electronic probably rotating speed can be very high, that patient cannot bear pain.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of hand rotary apparatus for dentistry prong,
This utility model is achieved through the following technical solutions: a kind of hand rotary apparatus for dentistry prong, comprise body, the right-hand member of described body is provided with hands handle, the downside of described body right-hand member is provided with pilot hole, described inner right-hand member is provided with auxiliary sheave left end and is provided with gear, the two ends up and down of described gear are provided with boss, the centre of described gear is provided with axial centre bore, the inside of described body is also provided with belt, described belt wrap is on auxiliary sheave and gear, tooth block on described belt and gears meshing, described guide pad is cemented on belt by pilot hole, inside described centre bore, prong is installed, described prong is inserted into inside the root pipe of the root of the tooth of tooth.
As optimal technical scheme of the present utility model, the sidewall of described axial centre bore is provided with anti-slip material.
As optimal technical scheme of the present utility model, the left end inside described belt is provided with tooth block.
As optimal technical scheme of the present utility model, described guide pad is provided with slipmat.
Compared with prior art, the beneficial effects of the utility model are: this utility model devises: a kind of hand rotary apparatus for dentistry prong, logical guide pad, pilot hole, effective combination of belt and gear solves prior art Problems existing, can be that prong is installed in hand rotary apparatus by arranging axial centre bore on gear, by arranging anti-slip material on the sidewall of the centre bore of axis, when preventing gear from rotating, prong skids, by arranging slipmat on guide pad, prevent people's hand propelled guide pad from being skid, rotator is arranged to manual can be applicable to different sick Man's Demands, prevent from rotating and too fastly bring pain to patient, this utility model relates to rationally, structure is simple, easy to use.
