Porous titanium alloy supporting rod and preparation method and application thereof

Abstract

The invention relates to the technical field of bone transplantation, and particularly discloses a porous titanium alloy supporting rod and a preparation method and application thereof. The porous titanium alloy supporting rod comprises a head body part and a tail part which are fixedly connected, the head body part is in a net-shaped porous cylinder shape and is composed of a plurality of hexagonal honeycomb type structure units, and the tail part is a solid cylinder. The average pore size of the porous titanium alloy supporting rod ranges from 700 micrometers to 800 micrometers, the porosity ranges from 70% to 75%, and the average wire diameter ranges from 340 micrometers to 400 micrometers. The bearing capacity of the porous titanium alloy supporting rod reaches up to 713N, the porous titanium alloy supporting rod can be effectively integrated with in-vivo bone tissue, stent osteogenesis is promoted, and the osteogenesis amount is increased.
