The invention discloses an individual osteosarcoma cervical vertebra prosthesis. The individual osteosarcoma cervical vertebra prosthesis comprises a fixing plate and a supporting body arranged on the surface of the inner side of the fixing plate. The supporting body can be placed into a focus formed after a bone tumor segment of a patient is excised, the supporting body and the fixing plate are integrally molded, the fixing plate is provided with a profiled surface which can be in matched fit with a bone body around the focal area of the patient, and a plurality of nail placing holes are formed in the fixing plate. The supporting body and the fixing plate are integrally molded, the fixing plate and the supporting body are prevented from being separated in the prosthesis installation process, fixation efficacy losing is avoided, meanwhile, the fixing plate can be individually designed according to a preoperative CT and MRI images, and the fixing plate is provided with the profiled surface in matched fit with the bone body around the patient focal area; due to the adopted profiled design, effective nail placement does not need to be performed according to the specific condition of each patient, nail arrangement during operation is convenient, the operation time is shortened, and bone substance replacement is prevented from being affected after operation.
Description
Technical field
The present invention is used for technical field of medical instruments, particularly relates to a kind of personalized osteosarcoma cervical prosthesis.
Background technology
Chordoma be a kind of geneogenous, derive from the primary malignant tumor of Embryo chordal tissue of remnants, be positioned at vertebra vertebral body and intervertebral disc, rare involve soft tissue before sacrum.Mainly being apt to occur in the person in middle and old age in 50-60 year, men and women falls ill no significant difference.Chordoma is not had obvious therapeutical effect by classic chemotherapy and radiotherapy.Therefore, operative treatment is most efficient method.But for spinal surgeons, it is achieved cervical vertebra chordoma en bloc resection is still a huge challenge.For Thoracolumbar disk multi-segmental chordoma patient, whole section of tumor resection can reduce the incidence rate of post-operative complication and improve the survival rate of patient.But the multi-segmental chordoma excision for cervical vertebra still suffers from huge challenge.Due to vital tissues such as the important anatomy structure that a cervical vertebra high position is complicated, a neighbour oblongata part, spinal cord, blood vessel, nerves, postoperative usually there is more complication.
Prior art there is problems in that in traditional operation
1, conventional steel plates adds that titanium cage is fixing occurs that bone laminating is bad, internal fixation system steel plate and titanium cage that the operation of current upper cervical spine bone tumor uses adopt unified manufacturing process, the steel plate matched with anatomic form of lacking individuality, and titanium cage needs plasticity in operation, increase operating time, the postoperative separation that titanium cage and steel plate often occur, solid failure.
2, ideal owed by the mid-nail of art: it is all different that the tumor size of each patient, sclerotin reject scope, needs the concrete condition according to each patient effectively to put nail in art, and tradition internal fixation steel plate there will be tumor region cloth nail difficulty, affects bony remodeling.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of personalized osteosarcoma cervical prosthesis, it can carry out personalized designs according to preoperative CT and MRI image, so as to match with the anatomic form of tumor section bone, good bone, docile effect can be reached, shorten operating time, facilitate cloth nail in art, it is to avoid the postoperative bony remodeling that affects is put.
The technical solution adopted for the present invention to solve the technical problems is: a kind of personalized osteosarcoma cervical prosthesis, including fixing plate and the supporter being located on described fixing plate inner surface, the intralesional that described supporter is formed after can inserting the excision of patient bone tumor sections, described supporter is one-body molded with fixing plate, described fixing plate has the contoured surface that can mate laminating with patient focal zone surrounding bone mass, and described fixing plate is provided with some puts nail.
It is further used as the improvement of technical solution of the present invention, described fixing plate and supporter by passing through 3D printing shaping after scanning patient bone volume modeling.
It is further used as the improvement of technical solution of the present invention, described supporter is positioned at the inside middle portion of described fixing plate, the top of described fixing plate is provided with the top tab stretched out to both sides, the bottom of fixing plate is provided with the bottom flaps extended downwardly from, described in put nail and be distributed in the marginal position of described top tab and bottom flaps.
It is further used as the improvement of technical solution of the present invention, puts nail described in each at the outer surface of fixing plate and be respectively formed counterbore.
Be further used as the improvement of technical solution of the present invention, described fixing plate be equipped with in the outside respectively putting nail and put nail guide pillar, described in put nail guide pillar offered the bootable pilot hole putting nail operation.
Be further used as the improvement of technical solution of the present invention, described in put nail guide pillar and be connected by micro-connecting rod and fixing plate are fixing, described micro-connecting rod can fracture easily, and make to put and follow closely guide pillar and depart from from fixing plate.
Being further used as the improvement of technical solution of the present invention, described supporter is the cage structure of porous.
Being further used as the improvement of technical solution of the present invention, described supporter is cylindrical, and the middle part of described supporter is provided with vertical through hole, and the top of supporter and bottom form the supporting surface of C shape, and the cylinder of supporter is offered the diamond hole that some and described through hole turns on.
Being further used as the improvement of technical solution of the present invention, described fixing plate is steel plate in uniform thickness.
Beneficial effects of the present invention: the present invention can carry out the fixing plate of personalized designs according to preoperative CT and MRI image, fixing plate is made to have the contoured surface that can mate laminating with patient focal zone surrounding bone mass, during use, the intralesional that supporter is formed after inserting the excision of patient bone tumor sections, fixing plate has and can mate laminating with patient focal zone surrounding bone mass, then follow closely at the cloth in nail of putting of fixing plate, it is finally completed the fixed installation at patient's lesions position of the whole prosthese, in the present invention, supporter is one-body molded with fixing plate, avoid prosthese installation process fixes plate and supporter is separated, avoid solid failure, simultaneously because employing contoured design, without effectively putting nail according to the concrete condition of each patient in art, thus facilitating cloth nail in art, shorten operating time, the postoperative bony remodeling that affects is avoided to put.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is first embodiment of the invention structural representation；
Fig. 2 is second embodiment of the invention structural representation.
Detailed description of the invention
