Abstract
The utility model discloses an artificial vertebral body, including the centrum main part, the equal fixedly connected with layer board in both ends of centrum main part, the upper surface of layer board is equipped with arch and fixed plate, just one side of the upper surface of support plate that the fixed plate is located, the upper surface middle part of layer board is equipped with first bolt, the screw has been seted up on the fixed plate, be equipped with the second bolt in the screw of fixed plate. This artificial vertebral body is through being provided with the fixed plate, just be provided with the second bolt on the fixed plate, has reached the fixed effect in artificial vertebral body side, through being provided with first bolt, reached the fixed effect in artificial vertebral body both ends, make artificial vertebral body fixed more firm, be difficult to the phenomenon of fixed failures such as run -off the straight and disconnected nail, through being provided with the arch, reached the effect that improves artificial vertebral body adhesive force, just reached and carried out the effect of fixing a position to artificial vertebral body, the utility model discloses simple structure is for artificial vertebral body and the biological compatible sufficient skeletonization space that provides of people's bone.
Description
Technical field
This utility model relates to bone surgery implanting prosthetic technical field, is specially a kind of artificial vertebral body.
Background technology
Vertebral body is the major part that vertebra bears a heavy burden, and inside is full of spongiosa, and the compact substance on surface is thinner, and top and bottom are all coarse, connect with adjacent vertebrae by means of fibrocartilagines intervertebrales.Micro-pits after vertebral body, surrounds vertebral foramen jointly with vertebral arch.Each vertebral foramen is through, forms the canalis spinalis holding spinal cord.
After the sufferer vertebral body of causing because of pathological changes (as tumor, intervertebral disk hernia etc.) or wound clinically at present carries out excision, need the artificial implants carrying out vertebral body.Artificial vertebral body is widely applied clinically as the effective vertebral body replacements of a class.Classical vertebral reconstructive devices is usually by titanium cage and steel plate screw System's composition, wherein, titanium cage is positioned over cut vertebral body position, play a supportive role, steel plate screw fixing system is used for two vertebral bodys up and down adjacent for cut vertebral body to be fixedly connected with, this mode that is connected and fixed is fixed loosely, and the easy fixing failed phenomenon such as run-off the straight or Duan Ding, the metal materials such as existing artificial vertebral body many employings titanium alloy are made, the common denominator of metal material is that its elastic modelling quantity is far longer than vertebral bone, biocompatibility is undesirable, be difficult to provide good fusion, long-term effect is poor, enough skeletonization spaces can not be provided for artificial vertebral body and people's bone bio-compatible.
Utility model content
The purpose of this utility model is to provide a kind of artificial vertebral body, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of artificial vertebral body, comprise vertebral body main body, the two ends of described vertebral body main body are all fixedly connected with supporting plate, the upper surface of described supporting plate is provided with projection and fixing head, and described fixing head is positioned at the side of splint upper surface, and the upper surface middle part of described supporting plate is provided with the first bolt, described fixing head offers screw, in the screw of described fixing head, is provided with the second bolt.
Preferably, described vertebral body main body comprises square vertebral body and square groove, and described square groove is opened in four sides of square vertebral body.
Preferably, described vertebral body main body comprises cylindricality vertebral body and manhole, and the inside of described cylindricality vertebral body is hollow structure, and described cylindricality vertebral body is offered offers manhole.
Preferably, described vertebral body main body comprises cylindricality vertebral body and rhombus through hole, and the inside of described cylindricality vertebral body is hollow structure, and described cylindricality vertebral body offers rhombus through hole, and described rhombus through hole is evenly distributed on cylindricality vertebral body with netted.
Preferably, the upper surface of described supporting plate is provided with bio-ceramic coating.
Compared with prior art, the beneficial effects of the utility model are: this artificial vertebral body, by being provided with fixing head, and described fixing head is provided with the second bolt, reach the fixing effect in artificial vertebral body side, by being provided with the first bolt, reach the fixing effect in artificial vertebral body two ends, make artificial vertebral body fixing more firm, the fixing failed phenomenons such as inclination and broken nail are less likely to occur, by being provided with projection, reach the effect improving artificial vertebral body adhesive force, and reach the effect that artificial vertebral body is positioned, by being provided with square groove, manhole or rhombus through hole, reach the effect improving artificial vertebral body and people's bone biocompatibility, the bio-compatible of behaviour bone and artificial vertebral body provides enough skeletonization spaces, by being provided with bio-ceramic coating, can for the implant initial stage fixedly play good effect.
