This utility model solves its technical problem and be the technical scheme is that a kind of bone tumor cervical prosthesis, including fixed plate and the supporter being located on described fixed 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 fixed plate, described fixed plate has the contoured surface that can mate laminating with patient focal zone surrounding bone mass, described fixed plate is provided with some nail of putting, each described in put nail and be respectively formed counterbore at the outer surface of fixed plate.
It is further used as the improvement of technical solutions of the utility model, described fixed plate and supporter by passing through 3D printing shaping after scanning patient bone volume modeling.
It is further used as the improvement of technical solutions of the utility model, described supporter is positioned at the inside middle portion of described fixed plate, the top of described fixed plate is provided with the top tab stretched out to both sides, the bottom of fixed 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.
Be further used as the improvement of technical solutions of the utility model, described fixed plate be equipped with in the outside respectively putting nail and put nail guide pillar, described in put and on nail guide pillar, offer the bootable pilot hole putting nail operation.
Be further used as the improvement of technical solutions of the utility model, described in put nail guide pillar and fixed by micro-connecting rod and fixed plate and be connected, described micro-connecting rod can fracture easily, and make to put and follow closely guide pillar and depart from from fixed plate.
Being further used as the improvement of technical solutions of the utility model, described supporter is the cage structure of porous.
It is further used as the improvement of technical solutions of the utility model, described supporter is cylindrical, 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-shaped, and the cylinder of supporter is offered some and the conducting of described through hole diamond hole.
Being further used as the improvement of technical solutions of the utility model, described fixed plate is steel plate in uniform thickness.
The beneficial effects of the utility model: this utility model can carry out personalized designs fixed plate according to preoperative CT and MRI image, fixed 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, fixed plate has can mate laminating with patient focal zone surrounding bone mass, then cloth nail in nail is put in fixed plate, it is finally completed the fixed installation at patient's lesions position of the whole prosthese, in this utility model, supporter is one-body molded with fixed plate, fixed plate and supporter in prosthese installation process is avoided to be separated, avoid solid failure, simultaneously because employing contoured design, without effectively putting nail according to the concrete condition of each patient in art, thus facilitate cloth nail in art, shorten operating time, the postoperative bony remodeling that affects is avoided to put.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is this utility model first embodiment structural representation；
Fig. 2 is this utility model the second example structure schematic diagram.
