Abstract
A kind of Vertebral defect method for reconstructing of individuation in conjunction with generalization obtains the data of upper and lower quadrate bone contact surface at Vertebral defect by digitizing to reverse-engineer；Outer surface is obtained according to the data of the bone contact surface of upper and lower and upper and lower quadrate bone contact surface matches, inner surface is standard interface Custom made stem；Then preparing upper and lower surface has several intermediate standard components of standard interface corresponding with Custom made stem inner surface standard interface；When being rebuild, it is connected using different intermediate standard components with Custom made stem component according to the size at Vertebral defect, upper and lower Custom made stem component, the press-fitting of intermediate standard component is obtained into Reconstruction of vertebral bone defects component together using press fitting device.Individual design of the present invention, which can guarantee to attach, to be contacted, and by selecting suitable modular unit, height, angle between centrum are easily adjusted in art.Simultaneously for each patient, only there are two components for individuation part, reduce manufacturing cost and period.
Description
Technical field
The present invention relates to a kind of Vertebral defect method for reconstructing applied to spinal surgery, and in particular to a kind of individuation and logical
With the Vertebral defect method for reconstructing for changing combination.
Background technique
Tumor of spine, regression or infection row vertebral resection are postoperative, can remain large-scale centrum bony defect, previous to adopt more
It is rebuild with standardized cylinder titanium alloy cage, this needs to be trimmed in the course of surgery, often time and effort consuming, but very
It is rare to rebuild effect to accurately support.Simultaneously because the local stress and interphase match problem of titanium alloy cage, make pine after implantation
The complication rates such as dynamic, sinking are higher.After metal 3D printing technique promotes and applies, the artificial vertebral body of Individual design starts to draw
Enter clinical application, to obtain better Anatomical Reconstruction effect, but the defect of this prosthese is to change after completing processing
Shape is deformed, once operation is not carried out according to preoperative plan, either large or small bony defect is all by unsuitable 3D printing individuation
The implantation of prosthese.Continuous design and the different several Individual design prostheses of stamp with the size are mostly used now, but the method is processed
Prosthese is individuation, is only used for sufferers themselves, both wastes material, it is also possible to desired size be not achieved.
Summary of the invention
The purpose of the present invention is to provide a kind of to combine individuation component with generalization component to rebuild Vertebral defect,
To reach Vertebral defect method for reconstructing of the arbitrarily adjustable individuation of interface anatomical compatibility and height and angle in conjunction with generalization.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
1) firstly, obtaining the data of upper and lower quadrate bone contact surface at Vertebral defect by digitizing to reverse-engineer；
2) it is contacted secondly, obtaining outer surface using 3D printing according to the data of the bone contact surface of upper and lower with upper and lower quadrate bone
The prosthese that face matches, inner surface is standard interface is as upper and lower Custom made stem component；
3) then, prepare height, diameter, top and bottom angulation angle be in be increased stepwise, while upper and lower surface have with it is a
Several intermediate standard components of the corresponding standard interface of body prosthese inner surface standard interface；
4) finally, when being rebuild, different intermediate standard components and individual are used according to the size at Vertebral defect
Change prosthesis assembly to be connected, is obtained upper and lower Custom made stem component, the press-fitting of intermediate standard component together using press fitting device
Reconstruction of vertebral bone defects component.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
This method may insure accurately to rebuild defect during surgery, and at the position of contact bone, Individual design can be protected
Card attaches contact, and by selecting suitable modular unit, height, angle between centrum can be easily adjusted in art.Simultaneously
For each patient, only there are two two components for individuation part, are greatly lowered manufacturing cost and period.Modular unit, can be with
Produce in enormous quantities in advance, because being suitable for all groups, effectively reduces waste of material.
Detailed description of the invention
Fig. 1 is centrum bony defect figure；
Fig. 2 is the upper and lower Custom made stem component 3,4 according to patient anatomical's design data；
Fig. 3 is the structural schematic diagram of intermediate standard component 5 of the present invention；
Fig. 4 is the structural schematic diagram that backbone bony defect component is rebuild after the present invention assembles.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
1) referring to Fig. 1, firstly, obtaining the number of upper and lower quadrate bone contact surface 1,2 at Vertebral defect by digitizing to reverse-engineer
According to；
2) referring to fig. 2, secondly, according to the data of the bone contact surface 1,2 of upper and lower using 3D printing obtain outer surface with
The prosthese that upper and lower quadrate bone contact surface matches, inner surface is standard interface 3-1,4-1 is as upper and lower Custom made stem component
3,4；
3) referring to Fig. 3, then, preparation height, diameter, top and bottom angulation angle are in be increased stepwise, while upper and lower surface
There are several intermediate standard groups of standard interface corresponding with Custom made stem 3,4 inner surface standard interface 3-1,4-1
Part 5；
4) referring to fig. 4, finally, when being rebuild, different intermediate standard groups are used according to the size at Vertebral defect
Part 5 is connected with Custom made stem component, using press fitting device by upper and lower Custom made stem component 3,4, intermediate standard component 5
Press-fitting obtains Reconstruction of vertebral bone defects component together.
The bone contact surface of present invention upper and lower at Vertebral defect is obtained matched with bone face by digitlization reverse engineer
Prosthetic surface, and then design individuation part up and down.There are two faces for individuation part tool, are on one side individuation synthetism face, and one
Face is standard interface.Middle section is modular unit, and the indexs such as height, diameter, top and bottom angulation angle are in ladder
It is incremented by, while upper and lower surface has standard interface, can match with individuation component.In the course of surgery, need to carry out weight
When building, it is connected using various criterion component with individuation component, effect is rebuild in test, until finding most suitable size, angle
Modular unit.3 components are press-fitted together using press fitting device, are implanted into Vertebral defect position.
