Titanium tantalum composite microsphere bone filling medical materials

A titanium tantalum bone composite microspheres filling the medicinal materials, whose character is: the bone filling described the medicinal material for titanium, tantalum composite microspheres including the titanium tantalum nanocomposite using tantalum plate manufacturers medical tantalum or tantalum wire woven porous microspheres, and in the center of the porous microspheres injection liquid titanium or titanium alloy liquid, cooling solidification after the formation of the titanium/tantalum two-phase composite microspheres composed of the core and winding type tantalum surface, porous layer consisting of microspheres within the surface of the microspheres containing bioactive coating for surface and drug loading of space. The invention significantly improves the strength and stiffness of bone filling medical materials and the high fatigue life under biological environment, maintains excellent biocompatibility and bone conductivity, and provides sufficient space and possibility for loading drugs and loading osteoinductive factors. It is suitable for all kinds of bone filling, repair and reconstruction in minimally invasive orthopedic clinic.

Preparation and antibacterial properties of titanium and tantalum based antibacterial materials

In recent years, the demand of antibacterial materials and antibacterial products is increasing. Research and development of new antibacterial materials with environmental protection, stability, high efficiency and durability have become the current research focus. As an inorganic antibacterial agent, nano silver not only shows good characteristics of broad-spectrum antibacterial, strong permeability, efficient bactericidal, durable antibacterial and non-toxic, but also has the function of repairing and regenerating biological wounds and has become one of the first choice antibacterial agents for People's Daily needs. Tantalum and titanium both have good biological stability, biocompatibility and bioactivity, as well as non-toxicity to the body tissue. Tantalum and titanium can be used as an ideal artificial bone joint implant material, and has gradually become a new direction in the development of bone tissue engineering. However, tantalum and titanium can be prepared into porous structure, which can be extracted substantially.

Tantalum and titanium can be used as an ideal artificial bone joint implant material, and has gradually become a new direction in the development of bone tissue engineering. The porous structure made of tantalum and titanium can greatly improve the bonding strength with human bone. Because the bio-nutrients can freely pass through the porous structure and provide nutrients for the newly formed bone tissue in the porous material, it is beneficial for the bone tissue to grow into the porous material and connect with the bone tissue around the implanted material. But implant materials can also cause a variety of surgical sequelae due to bacterial infections during use. By adding antimicrobial agents to the implant material, the implant itself becomes antibacterial, reducing the risk of surgery caused by bacteria.
