Description
Technical field
The invention belongs to Design for Medical Device technical field, more particularly, to a kind of hip for adapting to different type acetabular defects
Mortar rebuilds prosthesis system.
Background technology
The AAOS hips committee in 1989 designs the acetabular defects parting system for clinically using and still effectively using so far
System, acetabular defects are divided into five types by the system, as shown in figure 1, I types：Segmental pattern defect (figure A, figure B)；II types：Intracavitary type
Defect (figure C, figure D)；Type III：Mixed type defect (figure E)；IV types：Pelvis interrupt-type (figure F)；V-type：Joint fusion type (figure G).
Acetabular defects can not be solved using conventional acetabular component, can only use the acetabulum reconstruction prosthese solution for acetabular defects, but
Often a kind of acetabulum reconstruction prosthese can not solve all types of acetabular defects at all, therefore, and design is a set of to can adapt to difference
The acetabulum reconstruction prosthesis system of type acetabular defects is those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
The problem to be solved in the present invention be to provide it is a kind of the pivot of hip joint is recovered to anatomical position, reduce postoperative
Loosen, set up normal joint motion mechanism, the structural intergrity of Acetabular reconstruction, the adaptation different type acetabular defects of fixation
Acetabulum reconstruction prosthesis system.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of adaptation different type acetabular defects
Acetabulum reconstruction prosthesis system, including acetabulum reconstruction cushion block, acetabulum reconstruction titanium net and acetabulum reconstruction bracket；The acetabulum reconstruction cushion block

The demand of size acetabular bone.
Due to using above-mentioned technical proposal, acetabulum reconstruction cushion block, acetabulum reconstruction titanium net and acetabulum reconstruction bracket basis respectively
Different acetabular defects type Cranial defect situation designs, (1) acetabulum reconstruction cushion block meets the defect of acetabular bone peripheral edge portion, and realization is filled out
The effect of Cranial defect is filled, its surface is covered with nail, be easy to acetabular bone screw to be firmly secured to the preferable position of acetabular bone sclerotin, it is real
Filling and supporting role at existing defect, reach the stable effect of immediate postoperative, are divided into different specifications and models, meet different big
The demand of small acetabular bone, it is adaptable to I type segmental pattern defects and type III mixed type defect；(2) acetabulum reconstruction titanium net meets the whole of acetabular bone
Volume morphing, the lacuna type in acetabular bone that meets needs the defect of bone grafting to dispose, the design of its 5 flap-type, facilitates a certain position in art to weigh
Directly cut off when building titanium net, convenient, flexible, its surface is covered with nail, be easy to acetabular bone screw be firmly secured to acetabular bone sclerotin compared with
Good position, realizes the filling and supporting role at defect, reaches the stable effect of immediate postoperative, point different specifications and models,
Meet the demand of different size acetabular bone, it is adaptable to II die cavity inner mold defects and type III mixed type defect；(3) acetabulum reconstruction bracket,
Divide left and right sides band three wings anatomic form design, effectively solve the acetabulum reconstruction of serious acetabular defects and be fixedly secured problem, its table
Face is covered with nail, is easy to acetabular bone screw to be firmly secured to the preferable position of acetabular bone sclerotin, realizes the filling at defect and branch
Support is acted on, and reaches the stable effect of immediate postoperative, and point different specifications and models meet the demand of different size acetabular bone, it is adaptable to
IV type pelvis interrupt-types and V-type joint fusion type.
The beneficial effects of the invention are as follows：With the pivot of hip joint is recovered to anatomical position, postoperative 30% is reduced
Loosening occur；Set up normal joint motion mechanism；The structural intergrity of Acetabular reconstruction；Firm bone grafting is by the abundant ring of new prosthese
Embrace, acetabulum reconstruction prosthese is fixedly secured to the advantage on host bone.
