Abstract
A kind of 3D printing micropore inserted type skeletal grain, including：Column and micropore；Skeletal grain is three-dimensional structure, is made of six orthogonal columns, and column is round table-like, and wide at the top and narrow at the bottom, the relatively narrow tail portion in lower part links together, and constitutes three-dimensional structure；Containing there are many micropores in skeletal grain；Every three adjacent columns can form an infundibulate and be fitted into mouth；The 3D printing micropore inserted type skeletal grain can provide favorable environment for bone repair, can either stablize during bone grafting effectively moulding, and can improve bone repair rate.
Description
Technical field
The present invention relates to a kind of skeletal grain, especially a kind of 3D printing micropore inserted type skeletal grain.
Background technology
Hip joint disease is varied, such as the frequent companion such as congenital dislocation of hip joint, serious Osteoarthritis, wound
There is the defect of acetabular bone sclerotin.When acetabular bone bony defect, it is often necessary to be treated by bone grafting operation, but can occurred in performing the operation
Moulding bad, the covering of the outer upper limb or acetabular bone bottom sclerotin of acetabular bone is less, or the Bone mineral change on acetabular bone contact surface feelings
Condition, postoperative bone grafting position are easy for loosening, and cause bone repair rate not high.
Invention content
In order to overcome it is moulding during current bone grafting be not sufficiently stable, the not high problem of bone repair rate, the present invention provides one
Kind 3D printing micropore inserted type skeletal grain, the 3D printing micropore inserted type skeletal grain can be generated by 3D printing, be used for bone grafting operation
For bone repair favorable environment can be provided, can either stablize during bone grafting effectively moulding, and sclerotin can improved and repaiied
Multiple rate.
The technical solution adopted by the present invention to solve the technical problems is：The 3D printing micropore inserted type skeletal grain includes：Column
Shape body and micropore；Skeletal grain is three-dimensional structure, is made of six orthogonal columns, and column is round table-like, under upper width
Narrow, the relatively narrow tail portion in lower part links together, and constitutes three-dimensional structure；Containing there are many micropores in skeletal grain；Every three adjacent columns
Body can form an infundibulate and be fitted into mouth, and it is embedded and by its clamping which can just accommodate another column；It is micro-
The required calcification particle of osteogen can be filtered and be deposited in hole, repaired for bony defect position and provide favorable environment.
In use, since hip joint disease causes a large amount of bone-loss between hipbone, acetabular bone bony defect is caused；To this
When acetabular bone carries out bone grafting, behind a large amount of skeletal grain merging bone defect position, under the pressure effect of pressure device, the column of a skeletal grain
The infundibulate that body is embedded in another skeletal grain is fitted into mouth, and then each skeletal grain is firmly combined together, and forms form and bone
The skeletal grain group that matter defect matches；Micropore in skeletal grain is filtered and deposits the required calcification particle of osteogen, is
Bone repair provides favorable environment.
The beneficial effects of the invention are as follows：The 3D printing micropore inserted type skeletal grain can provide favorable environment for bone repair,
It can either stablize effectively moulding during bone grafting, and bone repair rate can be improved.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of 3D printing micropore inserted type skeletal grain.
Fig. 2 is to carry out acetabular bone bone grafting schematic diagram with 3D printing micropore inserted type skeletal grain.
In figure, 1. skeletal grains, 2. columns, 3. micropores, 4. hipbones, 5. skeletal grain groups, 6. pressure devices, 7. defects.
Specific implementation mode
In Fig. 1, skeletal grain 1 includes：Column 2 and micropore 3；Skeletal grain 1 is three-dimensional structure, by six orthogonal columns
2 compositions, column 2 is round table-like, and wide at the top and narrow at the bottom, the relatively narrow tail portion in lower part links together, and constitutes three-dimensional structure；Skeletal grain 1
In containing there are many micropore 3；Every three adjacent columns 2 can form an infundibulate and be fitted into mouth, which can just
Accommodate the insertion of another column 2 and by its clamping；Micropore 3 can filter and deposit the required calcification particle of osteogen, be
It repairs bony defect position 7 and favorable environment is provided.
In use, in fig. 2, since hip joint disease causes a large amount of bone-loss between hipbone 4, acetabular bone sclerotin is caused
Defect；When carrying out bone grafting to the acetabular bone, after a large amount of skeletal grain 1 is placed in bone defect position 7, under the pressure effect of pressure device 6, one
The infundibulate that the column 2 of a skeletal grain 1 is embedded in another skeletal grain 1 is fitted into mouth, and then each skeletal grain 1 is firmly bonded to one
It rises, and forms the skeletal grain group 5 that form matches with bony defect position 7；Micropore 3 in skeletal grain 1 is filtered and deposits skeletonization
The required calcification particle of matter, favorable environment is provided for bone repair.
