Abstract
The utility model relates to a matched stack formula acetabular bone false body, including mortar cup false body and acetabular bone inside lining false body. Mortar cup false body includes interior sphere, first cylinder screw and sinks the platform through -hole, acetabular bone inside lining false body includes spherical outside surface, recess and second cylinder screw. First cylinder screw with the meshing of second cylinder screw realizes mortar cup false body with the matched stack of acetabular bone inside lining false body.
Description
Technical field
This utility model relates to the artificial prosthesis of a kind of orthopaedics acetabular bone displacement, particularly a kind of a kind of assembly type acetabular component used in acetabuloplasty.
Background technology
In acetabuloplasty, assembly type acetabular component is usually adopted to substitute the acetabular bone of human lesion. Assembly type acetabular component includes mortar cup prosthesis and acetabular bone liner prosthese. When clinical operation, first mortar cup prosthesis is implanted in the mortar nest of human body, then acetabular bone liner prosthese is assembled in mortar cup prosthesis.
Mortar cup prosthesis is often prepared by the metal material of biocompatibility. Acetabular bone liner prosthese is then often prepared by polythene material.
Finding in clinical observation, the failed common cause of existing acetabular component is that liner prosthese locking mechanism in mortar cup prosthesis is unstable, causes polyethylene liner prosthesis wear, forms bone and dissolves, and causes last displacement failed.
Utility model content
Acetabular component of the present utility model, acetabular bone liner prosthese has the locking effect of excellence in mortar cup prosthesis, and installation is convenient to.
This utility model solves its technical problem and be employed technical scheme comprise that a kind of acetabular component of offer, and it is made up of acetabular bone liner prosthese, mortar cup prosthesis and optional tapping screw. Described acetabular bone liner prosthese includes spherical outside surface, groove and the second cylinder screw thread; Described mortar cup prosthesis includes Internal Spherical Surface, the first cylinder screw thread and heavy stand through hole. When assembling, rotate described acetabular bone liner prosthese by the groove on acetabular bone liner prosthese, make the second cylinder screw thread of described acetabular bone liner prosthese and the first cylinder threaded engagement of mortar cup prosthesis, it is achieved the group of described acetabular bone liner prosthese and described mortar cup prosthesis is joined. Optionally, after acetabular bone liner prosthese and mortar cup prosthesis group are joined, tapping screw is shot in described acetabular bone liner prosthese by the heavy stand through hole of described mortar cup prosthesis, fixing to assist.
The pitch of described first cylinder screw thread and the second cylinder screw thread is less than or equal to 2mm.
The beneficial effects of the utility model are: locking effect is stable, easy for installation.
Accompanying drawing explanation
Fig. 1 is the sectional view of the assembly type acetabular component according to a kind of embodiment of the present utility model;
Fig. 2 is the acetabular bone liner prosthese of the assembly type acetabular component shown in Fig. 1;
Fig. 3 is the mortar cup prosthesis of the assembly type acetabular component shown in Fig. 1;
Fig. 4 is the sectional view of the assembly type acetabular component according to another embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described, but this utility model is not limited to following embodiment.
Fig. 1, Fig. 2 and Fig. 3 illustrate the assembly type acetabular component according to a kind of embodiment of the present utility model.This assembly type acetabular component includes mortar cup prosthesis 1 and acetabular bone liner prosthese 2. Mortar cup prosthesis 1 includes Internal Spherical Surface the 9, first cylinder screw thread 7 and heavy stand through hole 8; Acetabular bone liner prosthese includes spherical outside surface 4, groove 6 and the second cylinder screw thread 5. When mortar cup prosthesis 1 and the 2 groups of timings of acetabular bone liner prosthese, acetabular bone liner prosthese 2 is rotated by groove 6, the second cylinder screw thread 5 of acetabular bone liner prosthese 2 is made to engage with the first cylinder screw thread 7 of mortar cup prosthesis 1, it is achieved the group of acetabular bone liner prosthese 2 and mortar cup prosthesis 1 is joined, as shown in Figure 1.
Fig. 4 illustrates the assembly type acetabular component according to another embodiment of the present utility model, including mortar cup prosthesis 1, acetabular bone liner prosthese 2 and tapping screw 3. When mortar cup prosthesis 1 and the 2 groups of timings of acetabular bone liner prosthese, rotate acetabular bone liner prosthese 2 by groove 6, make the second cylinder screw thread 5 of acetabular bone liner prosthese 2 engage with the first cylinder screw thread 7 of mortar cup prosthesis 1, it is achieved the group of acetabular bone liner prosthese 2 and mortar cup prosthesis 1 is joined. Then, by the heavy stand through hole 8 of mortar cup prosthesis 2, tapping screw 3 is screwed in acetabular bone liner prosthese 2, further auxiliary acetabular bone liner prosthese 2 fixing in mortar cup prosthesis 1.
Preferably, the pitch of cylinder screw thread 5 is less than or equal to 2mm.
Mortar cup prosthesis of the present utility model and tapping screw are prepared by the metal material of biocompatibility, it is preferable that standby by titanium alloys.
Acetabular bone liner prosthese of the present utility model is prepared by biocompatible materials, it is preferable that prepared by ultra-high molecular weight polyethylene, crosslinking with radiation superhigh molecular weight polyethylene material.
