Further, the connecting portion is adapted to perforation, the profile and the internal orifice shape adaptation of perforation of the implanting portion, institute
State the profile and the collar extension shape adaptation of perforation of covering part.
As a preferred embodiment, the connecting portion is cylinder, the implanting portion, covering part are patty, implanting portion, connection
Portion, the axis of covering part overlap.
Preferably, the connecting portion and implanting portion, the junction rounding of covering part, the implanting portion, the edge of covering part
Equal rounding.
Another preferably the connecting portion is strip, and implanting portion, connecting portion, the axis of covering part overlap.
Preferably, the implanting portion, connecting portion and covering part are integrally manufactured.
Preferably, the implanting portion, connecting portion, the material of covering part are silicon rubber.
Further preferred, the silicon rubber is medical grade silicon rubber.
The invention also discloses a kind of manufacture method of the dummy, comprise the steps：
Step 1, the site of perforation to patient carry out CT scan, obtain the image information of site of perforation；
Step 2, the physical dimension for determining according to described image information implanting portion, connecting portion and covering part；
Step 3, the threedimensional model for establishing according to the physical dimension dummy；
Step 4,3D printer printing dummy is used according to the threedimensional model, the base material of printing is silicon rubber.
Preferably, in step 2, physical dimension is determined using following rules：
The gap of the connecting portion and perforation is 0 to 0.3 millimeter；
The length of connecting portion is smaller than the thickness of site of perforation organized layer 0.5 to 4.0 millimeter；
The distance of implanting portion, the outer of covering part and connecting portion is 1.0 to 10.0 millimeters；
Implanting portion, the thickness of covering part are 0.2 to 2.5 millimeter.
Application method of the present utility model：Perforated for maxilla, nasal cavity, connecting portion are put into after implanting portion is compressed from oral cavity
In perforation, pasted after the expansion of implanting portion with nasal cavity inner surface, covering part is bonded with oral cavity portion.
The utility model is also applied for the reparation of perforation of nasal septum.
The beneficial effects of the utility model are as follows：
1st, good seal performance of the present utility model, liquid not easily pass through perforated portion and flowed into and out, and can mitigate patient suffering.
2nd, connecting portion is worked good with what is perforated, is had supporting role to the tissue growth of site of perforation, is advantageous to defective tissue
Growth and reparation.
3rd, the utility model is simple in construction, and cost is low, good effect.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model；
In figure：1- covering parts, 2- connecting portions, 3- implanting portions.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As shown in Figure 1 and Figure 2, dummy disclosed in the utility model, including implanting portion 3, connecting portion 2 and covering part 1, even
Longitudinal both ends of socket part 2 connect implanting portion 3, the end face 1 of covering part respectively, and the lateral dimension of connecting portion 2 is less than implanting portion 3, covered
The lateral dimension of cap 1；Connecting portion 2 is adapted to perforation, the profile and the internal orifice shape adaptation of perforation of implanting portion 3, covering part 1
Profile and the collar extension shape adaptation of perforation.
If perforation is circular or subcircular (in most cases), implanting portion 3, covering part 1 use patty, described
Linking part 2 is using cylinder；If perforation is other shapes, such as strip or other irregular shapes, then implanting portion 3, covering part 1
The shape similar to inside and outside aperture is respectively adopted, connecting portion 2 uses and perforated portion shape identical body.
Connecting portion 2 and implanting portion 3, the junction rounding of covering part 1, implanting portion 3, connecting portion 2, the axis weight of covering part 1
Close, the radial dimension of connecting portion 2 is less than implanting portion 3, the radial dimension of covering part 1, implanting portion 3, connecting portion 2 and covering part 1 one
Body manufactures；Implanting portion 3, connecting portion 2, the material of covering part 1 are medical grade silicon rubber.
The invention also discloses a kind of manufacture method of the dummy, comprise the steps：
Step 1, the site of perforation to patient carry out CT scan, obtain the image information of site of perforation；
Step 2, the physical dimension for determining according to described image information implanting portion, connecting portion and covering part；
Step 3, the threedimensional model for establishing according to the physical dimension dummy；
Step 4,3D printer printing dummy is used according to the threedimensional model, the base material of printing is silicon rubber.
Preferably, in step 2, physical dimension is determined using following rules：
Connecting portion should be as far as possible closely sealed in principle, thus linking part should with perforated portion with size or less than with perforate joint portion
0.1 millimeter to 0.3 millimeter, reach the closely sealed effect of neither tight and can.
The length of connecting portion should be less than 0.5 millimeter to 4.0 millimeters of the thickness of perforation organized layer in principle, according to aperture size
