Porous tantalum rod |
| abstract |
The invention relates to a medical implant part for femoral head joint surface depression or I-stage or II-stage femoral head necrosis, namely a porous tantalum rod. One end of the implant part is provided with a connection fastening structure connected with a bone tissue, and a through hole is formed in the center of the tantalum rod; the porous tantalum rod is made of a porous tantalum material with a foam structure of pore three-dimensional communicated distribution, and is sintered by adopting a foam impregnation method; and tantalum powder particles have a sinter neck structure on a foam frame formed by accumulating the sintered pure tantalum powder. The through hole in the porous tantalum rod facilitates accurate positioning in an operation; and a related object can be picked out and injected conveniently through the through hole, so that the effect of constant pressure reduction can be achieved. |
