Abstract
The utility model relates to a kind of centrum support, including the first pipe portion, reticular part and the second pipe portion；One end of the reticular part is connected to first pipe portion, and the other end is connected to second pipe portion；The reticular part is made of multiple first stripes and multiple second stripes intersection, and two neighboring first stripes and two neighboring second stripes surround mesh；Before the centrum support struts, the reticular part is configured to cylindric, and the diameter of the cylinder is equal with the diameter of first pipe portion and second pipe portion；After the centrum support struts, the reticular part is configured to oval spherical.The centrum support of the utility model uses reticular structure, not only increases stability, and the centrum support stress is relatively uniform, also improves centrum recovery effects.
Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of centrum supports.
Background technique
Vertebral body balloon expansion plasty is a Minimally invasive procedure operation, is drilled on the limbs of compression, by a spy
The air bag of the about 15mm size of system is sent into centrum center, then inflates to air bag, and the air bag of expansion gradually props up the centrum collapsed,
Until centrum shape is restored to normal vertebral body, sacculus is removed, then bone cement is injected to the cavity at centrum center by the hole.Bone
The strength and stability that centrum can be enhanced after theing cement solidifies, this guarantees the centrums of recovery to be compressed, and backbone is abnormal
Shape is also just repaired.Bone cement used in vertebral body balloon expansion plasty is a kind of for filling and implantation material gap or bone
Chamber and the biomaterial with self-solidifying characteristic, main component is polymethyl methacrylate, and cement reaction can guarantee postoperative
The instant stabilization of prosthese.
For the support bar of existing centrum support mostly using the form of double fulcrums, stability is general, and misoperation is held
Easily expansion body is broken, there are security risks；Or multiple apertures are set on centrum support, centrum support forms more when expanding
Metal supporting surface, although improving stability, the centrum support discontinuity, centrum recovery effects need to be mentioned
It is high.
Utility model content
In view of the drawbacks described above of the prior art, it is good that the purpose of the utility model is to provide a kind of stability, uniform force
Centrum support.
The purpose of this utility model is achieved through the following technical solutions:
A kind of centrum support, including the first pipe portion, reticular part and the second pipe portion；One end of the reticular part is connected to institute
The first pipe portion is stated, the other end is connected to second pipe portion；The reticular part is by multiple first stripes and multiple Article 2
Shape portion intersects composition, and two neighboring first stripes and two neighboring second stripes surround mesh；The centrum support support
Before opening, the reticular part is configured to cylindric, the diameter of the diameter of the cylinder and first pipe portion and second pipe portion
It is equal；After the centrum support struts, the reticular part is configured to oval spherical.
Further, the centrum support is strutted by balloon catheter for expanding vertebra.
Compared with the existing technology, the characteristics of the utility model and progressive as follows:
1, before the centrum support of the utility model struts, reticular part is configured to cylindric, the diameter of the cylinder and the first pipe
The diameter of portion and the second pipe portion be it is equal, setting in this way makes centrum support overall profile be conducive to centrum support without lofty
It is placed in centrum.
2, after the centrum support of the utility model struts, reticular part is configured to oval spherical, meets the profile of centrum, guarantees
Centrum upper and lower faces after strutting are restored to the vertebral height before lesion.
3, the centrum support of the utility model uses reticular structure, not only increases stability, and the centrum support by
Power is relatively uniform, also improves centrum recovery effects.
Detailed description of the invention
Fig. 1: the structure chart of centrum support (before strutting)；
Fig. 2: the structure chart of centrum support (after strutting).
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figs. 1-2, a kind of centrum support 1, including the first pipe portion 11, reticular part 12 and the second pipe portion 13；It is netted
The one end in portion 12 is connected to the first pipe portion 11, and the other end is connected to the second pipe portion 13；Reticular part 12 is by multiple first stripes 121
And multiple second stripes 122 intersect composition, two neighboring first stripes 121 and two neighboring second stripes 122
Surround mesh 123；Before the centrum support 1 struts, reticular part 12 is configured to cylindric, the diameter of the cylinder and the first pipe portion 11
And second pipe portion 13 diameter be it is equal, setting in this way makes centrum support overall profile be conducive to centrum support without lofty
It is placed in centrum；After the centrum support 1 struts, reticular part 12 is configured to oval spherical, meets the profile of centrum, after guarantee struts
Centrum upper and lower faces be restored to the vertebral height before lesion；The centrum support 1 uses reticular structure, not only increases steady
Solidity, and the centrum support stress is relatively uniform, also improves centrum recovery effects.The utility model passes through vertebral body augmentation ball
Ductus bursae struts the centrum support 1, and fills artificial bone in the centrum support 1.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
Claims (2)
