Planting body acid etching fitting device
Technical field
Oil the technical field of waste acid erosion the utility model is related to planting body, especially a kind of planting body acid etching tooling dress
It sets.
Background technology
Mouth cavity planting body is also known as dental implant, also known as artificial tooth root, is the structural representation of planting body as shown in Figure 1
Figure, external is thread(1), inside offers internal thread, and the periphery on head is annular smooth surface(2), annular smooth surface(2)With vacation
Tooth is connected.Planting body is implanted by way of surgical operation in the up or down jawbone at human body agomphosis position, waits for its operation
After wound healing, thread(1)It is combined as a whole with up or down jawbone.Planting body before use, due to its surface be attached with greasy dirt and
Impurity, it is therefore necessary to acid etching be carried out to plantation external surface using acid solution, to remove greasy dirt and impurity.
It cannot be to annular smooth surface in etching process(2)Acid etching is carried out, because can corrode after annular smooth surface contact acid, can be caused
It cannot be stably connected with well with artificial tooth.Therefore annular smooth surface must be protected in acid cleaning process.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, effective protection is annular
Smooth surface, Rapid tooling planting body, planting body acid etching fitting device easy to operate.
The purpose of this utility model is achieved through the following technical solutions:Planting body acid etching fitting device, it includes ceramics
Outer barrel, inner cylinder and cross threaded rod, the ceramic outer barrel bottom offer stepped hole, connection are offered at the top of ceramic outer barrel
The annular groove of stepped hole, the inner cylinder are plugged in the macropore of stepped hole, and threaded hole A, inner cylinder bottom are offered at the top of inner cylinder
Portion offers threaded hole B, and the cross threaded rod is made of upper thread head connected in sequence, annular element and lower thread head,
Lower thread head sequentially runs through annular groove, the aperture of stepped hole and is threadedly coupled with threaded hole A, and annular element is set to annular groove
It is interior and press on annular groove bottom.
The nominal diameter of the upper thread head is more than the nominal diameter of lower thread head.
The center line of the annular groove is overlapped with the center line of stepped hole.
The aperture of the annular groove connection stepped hole.
The threaded hole A is connected to threaded hole B.
The inner cylinder bottom face is concordant with ceramic outer barrel bottom face.
The utility model has the following advantages:(1)The lower thread head of the utility model sequentially runs through annular groove, stepped hole
Aperture and be threadedly coupled with threaded hole A, annular element is set in annular groove and presses on annular groove bottom, need to will only plant
The internal thread of implant is threadedly coupled with upper thread head, to realize the Rapid tooling of planting body, improves the tooling of planting body
Efficiency.(2)In annular smooth surface embedded rings shape slot, the annular smooth surface of annular groove and planting body forms interference fit, to effectively keep away
Annular smooth surface is exempted from by acid liquid corrosion.

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described:
As shown in Fig. 2 ~ 5, planting body acid etching fitting device, it includes ceramic outer barrel 3, inner cylinder 4 and cross threaded rod, institute
3 bottom of ceramic outer barrel stated offers stepped hole 5, and 3 top of ceramic outer barrel offers the annular groove 6 of connection stepped hole 5, annular
The center line of groove 6 is overlapped with the center line of stepped hole 5, and the inner cylinder 4 is plugged in the macropore of stepped hole 5,4 top of inner cylinder
Threaded hole A7 is offered, 4 bottom of inner cylinder offers threaded hole B8, and the cross threaded rod is by upper thread head connected in sequence
9, annular element 10 and lower thread head 11 composition, the nominal diameter of upper thread head 9 are more than the nominal diameter of lower thread head 11, lower screw thread
First 11 sequentially run through annular groove 6, the aperture of stepped hole 5 and are threadedly coupled with threaded hole A7, and it is recessed that annular element 10 is set to annular
In slot 6 and 6 bottom of annular groove is pressed on, therefore forms annular groove between annular groove 6 and annular element 10, the groove width of annular groove
It can just be formed and be interference fitted with the annular smooth surface of planting body.
The annular groove 6 is connected to the aperture of stepped hole 5.The threaded hole A7 is connected to threaded hole B8.Described
4 bottom face of inner cylinder is concordant with ceramic 3 bottom face of outer barrel, and ceramic outer barrel 3 can avoid acid solution from being contacted with inner cylinder 4, prevents acid solution rotten
Lose inner cylinder 4.
The course of work of the utility model is as follows:As shown in fig. 6, first inner cylinder 4 is inserted in 5 macropore of stepped hole, then will
Lower thread head 11 passes through stepped hole 5 and is threadedly coupled with threaded hole A7, then only need to be by the internal thread of planting body 12 and upper screw thread
First 9 are threadedly coupled, and ensure that annular smooth surface 2 is embedded in annular groove, will kind after tooling to realize the Rapid tooling of planting body
Implant 12 is immersed in the slot for being loaded with acid solution, and acid solution can carry out acid etching to plantation external surface.Due to annular groove and plantation
The annular smooth surface of body 12 forms interference fit, to effectively prevent annular smooth surface by acid liquid corrosion.
