Abstract

A 3D (three-dimensional) printing micropore inlaying type bone grain comprises columnar bodies and micropores; the bone grain has a three-dimensional structure and consists of the six columnar bodies which are perpendicular to one another; the columnar bodies are in the shape of a circular truncated cone and have wide tops and narrow bottoms; narrow tails of the lower portions of the columnar bodies are connected together to form a three-dimensional structure; the bone grain comprises a plurality of micropores; and each three adjacent columnar bodies can form a funnel-shaped inlaying opening. The 3D printing micropore inlaying bone grain can provide an enabling environment for bone repair; shaping can be carried out stably and effectively in a bone grafting process; and bone repair rate can be improved.

Description

3D prints micropore inserted type skeletal grain

Technical field

The present invention relates to a kind of skeletal grain, especially a kind of 3D prints micropore inserted type skeletal grain.

Background technology

Hip joint disease is varied, and such as congenital dislocation of hip joint, serious osteoarthritis, wound etc. are often with the defect of acetabular bone sclerotin.During acetabular bone bony defect, usually need to be treated by bone grafting operation, but can occur moulding bad in operation, bottom the outer upper limb of acetabular bone or acetabular bone, sclerotin covers less, or the situation of the Bone mineral change on acetabular bone contact surface, postoperative bone grafting position just easily occurs to loosen, and causes bone repair rate not high.

Summary of the invention

Moulding stable not in order to overcome in current bone grafting process, the problem that bone repair rate is not high, the invention provides a kind of 3D and print micropore inserted type skeletal grain, this 3D prints micropore inserted type skeletal grain can print generation by 3D, favorable environment can be provided for bone repair for bone grafting operation, can either stablize effectively moulding in the process of bone grafting, bone repair rate can be improved again.

The technical solution adopted for the present invention to solve the technical problems is: this 3D prints micropore inserted type skeletal grain and comprises: column and micropore; Skeletal grain is three dimensional structure, and be made up of six orthogonal columns, column is round table-like, wide at the top and narrow at the bottom, and the narrower afterbody in bottom links together, and forms three dimensional structure; Containing many micropores in skeletal grain; Every three adjacent columns can form an infundibulate and be fitted together to mouth, and this chimeric mouth just can hold another column and embeds and clamped; Micropore can filter and be deposited as the calcification granule required for sclerotin, and repairing for bony defect position provides favorable environment.

During use, because hip joint disease causes a large amount of bone-loss between hipbone, cause acetabular bone bony defect; When bone grafting is carried out to this acetabular bone, after a large amount of skeletal grains inserts Cranial defect position, under the pressure effect of pressure device, the infundibulate that the column of a skeletal grain embeds another skeletal grain is fitted together in mouth, so each skeletal grain combines securely, and form the skeletal grain group that form and bony defect position match; Micropore in skeletal grain carries out filtering and is deposited as the calcification granule required for sclerotin, for bone repair provides favorable environment.

The invention has the beneficial effects as follows: this 3D prints micropore inserted type skeletal grain can provide favorable environment for bone repair, can either stablize effectively moulding, can improve bone repair rate again in the process of bone grafting.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Detailed description of the invention

In Fig. 1, skeletal grain 1 comprises: column 2 and micropore 3; Skeletal grain 1 is three dimensional structure, and be made up of six orthogonal columns 2, column 2 is round table-like, wide at the top and narrow at the bottom, and the narrower afterbody in bottom links together, and forms three dimensional structure; Containing many micropores 3 in skeletal grain 1; Every three adjacent columns 2 can form an infundibulate and be fitted together to mouth, and this chimeric mouth just can hold another column 2 and embeds and clamped; Micropore 3 can filter and be deposited as the calcification granule required for sclerotin, provides favorable environment for repairing bony defect position 7.

During use, in fig. 2, because hip joint disease causes a large amount of bone-loss between hipbone 4, acetabular bone bony defect is caused; When bone grafting is carried out to this acetabular bone, after a large amount of skeletal grains 1 inserts Cranial defect position 7, under the pressure effect of pressure device 6, the infundibulate that the column 2 of a skeletal grain 1 embeds another skeletal grain 1 is fitted together in mouth, so each skeletal grain 1 combines securely, and form the skeletal grain group 5 that form and bony defect position 7 match; Micropore 3 in skeletal grain 1 carries out filtering and is deposited as the calcification granule required for sclerotin, for bone repair provides favorable environment.
