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 invention：For maxilla perforation, be put into nasal cavity after implanting portion is compressed from oral cavity, connecting portion in
In perforation, implanting portion is fitted with nasal cavity inner surface patch, covering part after launching with oral cavity portion.
It is suitable for the reparation of perforation of nasal septum.
Beneficial effects of the present invention are as follows：
1st, good seal performance of the invention, liquid not easily passs through perforated portion and flows into and out, and can mitigate patient suffering.
2nd, connecting portion and working good for perforating, have supporting role to the tissue growth of site of perforation, are conducive to defective tissue
Growth and reparation.
3rd, simple structure of the present invention, low cost, good effect.
Brief description of the drawings
Fig. 1 is front view of the invention；
Fig. 2 is top view of the invention；
In figure：1- covering parts, 2- connecting portions, 3- implanting portions.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with accompanying drawing, the present invention is entered
Row is further described.
As shown in Figure 1 and Figure 2, dummy disclosed by the invention, including implanting portion 3, connecting portion 2 and covering part 1, connecting portion 2
Longitudinal two ends connect the end face 1 of implanting portion 3, covering part respectively, the lateral dimension of connecting portion 2 is less than implanting portion 3, covering part 1
Lateral dimension；Connecting portion 2 be adapted to perforation, the profile of implanting portion 3 and the internal orifice shape adaptation perforated, the profile of covering part 1
With 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 is used 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 is manufactured；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 that implanting portion, connecting portion and covering part are determined according to described image information；
Step 3, the threedimensional model that dummy is set up according to the physical dimension；
Step 4, dummy is printed using 3D printer 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 perforation joint portion
0.1 millimeter to 0.3 millimeter, reach neither tight and can be closely sealed effect.
