Abstract
A bone implant adapted to be implanted in a bone structure having a bone tissue, a cartilage tissue, and being formed with a hole is provided. The bone implant includes a scaffold disposed in the hole for connecting with the bone tissue, a connecting layer disposed on the scaffold, and a porous surface layer. The connecting layer includes a bottom portion connected to the scaffold and an extension portion extending from the bottom portion and formed with a plurality of receiving chambers. The porous surface layer is connected to the extension portion and includes a plurality of filler portions respectively filling the receiving chambers, and a tissue-connecting portion configured for connecting with the cartilage tissue.
Claims20
A bone implant adapted to be implanted in a bone structure, the bone structure including a bone tissue and a cartilage tissue connected to the bone tissue, and being formed with a hole, the hole extending through the cartilage tissue and into the bone tissue and having an opening at the cartilage tissue, said bone implant comprising:
- a scaffold configured to be disposed in the hole of the bone structure for connecting with the bone tissue;
- a connecting layer disposed on said scaffold and proximal to the opening of the hole, said connecting layer including a bottom portion that is connected to said scaffold, and an extension portion that extends from said bottom portion in a direction away from said scaffold and that is formed with a plurality of receiving chambers;
- and
- a porous surface layer connected to said extension portion of said connecting layer, said porous surface layer including a plurality of filler portions that respectively fill said receiving chambers, and a tissue-connecting portion that is connected to the filler portions and configured for connecting with the cartilage tissue,
- wherein said porous surface layer is composed of a plurality of stacked hollow microspheres, each of said hollow microspheres having an inner chamber, said inner chambers of any two adjacent ones of said hollow microspheres being in spatial communication with each other.
A bone implant adapted to be implanted in a bone structure, the bone structure including a bone tissue and a cartilage tissue connected to the bone tissue, and being formed with a hole, the hole extending through the cartilage tissue and into the bone tissue and having an opening at the cartilage tissue, said bone implant comprising:
- a scaffold configured to be disposed in the hole of the bone structure for connecting with the bone tissue;
- a connecting layer disposed on said scaffold and proximal to the opening of the hole, said connecting layer including a bottom portion that is connected to said scaffold, and an extension portion that extends from said bottom portion in a direction away from said scaffold and that is formed with a plurality of receiving chambers;
- and
- a porous surface layer connected to said extension portion of said connecting layer, said porous surface layer including a plurality of filler portions that respectively fill said receiving chambers, and a tissue-connecting portion that is connected to the filler portions and configured for connecting with the cartilage tissue,
- wherein said porous surface layer is composed of a plurality of stacked solid microspheres and formed with a plurality of pores distributed among said stacked solid microspheres.
A bone implant adapted to be implanted in a bone structure, the bone structure including a bone tissue and a cartilage tissue connected to the bone tissue, and being formed with a hole, the hole extending through the cartilage tissue and into the bone tissue and having an opening at the cartilage tissue, said bone implant comprising:
- a scaffold configured to be disposed in the hole of the bone structure for connecting with the bone tissue;
- a connecting layer disposed on said scaffold and proximal to the opening of the hole, said connecting layer including a bottom portion that is connected to said scaffold, and an extension portion that extends from said bottom portion in a direction away from said scaffold and that is formed with a plurality of receiving chambers;
- a porous surface layer connected to said extension portion of said connecting layer, said porous surface layer including a plurality of filler portions that respectively fill said receiving chambers, and a tissue-connecting portion that is connected to the filler portions and configured for connecting with the cartilage tissue, and
- an isolating layer disposed between said scaffold and said connecting layer so as to isolate said porous surface layer from being in fluidic communication with said scaffold through said connecting layer.
