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.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated; Should be appreciated that specific embodiment described herein only in order to explain this utility model, and to be not used in restriction be originally utility model.
A kind of hand rotary apparatus for dentistry prong as shown in Figure 1, comprise body 3, the right-hand member of described body 3 is provided with handle 1, the downside of described body 3 right-hand member is provided with pilot hole 10, the right-hand member of described body 3 inside is provided with auxiliary sheave 2 left end and is provided with gear 6, the two ends up and down of described gear 6 are provided with boss 9, described boss 9 is arranged on the medial wall of body 1, prevent gear 6 from axial skew occurring, the centre of described gear 6 is provided with axial centre bore 7, to install prong 13 inside described centre bore 7, the sidewall of described axial centre bore 7 is provided with anti-slip material 8, when the effect of described anti-slip material 8 is to prevent gear 8 from rotating, prong skids, the inside of described body 3 is also provided with belt 4, left end inside described belt 4 is provided with tooth block 5, described belt 4 is wrapped on auxiliary sheave 2 and gear 6, tooth block 5 on described belt 4 and gear 6 engage, described guide pad 11 is cemented on belt 4 by pilot hole 10, belt 4 is driven to rotate when the effect of described guide pad 11 is people's hand propelled guide pads 11, described guide pad 11 is provided with slipmat 12, the effect of described slipmat 12 prevents people's hand propelled guide pad 11 from being skid, inside centre bore 7, prong 13 is installed as described in Figure 2, described prong 13 is inserted into inside the root pipe of the root of the tooth of tooth 14.
Occupation mode: first operator are installed to prong 13 with inside centre bore 7, then handle 1 is held, inside root of the tooth root pipe prong 13 being inserted into tooth 14, with thumb by guide pad 11, front and back gently promote guide pad 11, guide pad 11 moves left and right along pilot hole 10, guide pad 12 drives belt 4 to move, tooth block 5 on belt 4 and gear 6 engage driven gear 6 and rotate, the prong 13 installed inside gear 6 also can together rotate, the root of insertion tooth 14 slowly, extract the neural blood vessel inside tooth root pipe, finally take out prong 13, clean after finishing the work.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
