Specific applications of niobium and titanium in the medical field

The application of niobium and titanium alloys in the medical field is mainly concentrated in the following aspects:

Orthopedic implants
• Joint replacement: Niobium and titanium alloys are widely used in knee and hip replacement surgery because of their elastic modulus matching that of human bones. The high fatigue strength of the alloy helps to improve the durability of implants.
• Bone plates and screws: Used to fix fractures or support bone structures to ensure bone healing.

Dental applications
• Dental implants: Niobium and titanium alloys are used in dental implants because of their excellent biocompatibility and corrosion resistance, which can effectively reduce the mechanical incompatibility between metal implants and bone tissue.
• Crowns and bridges: This alloy is suitable for making various dental restoration materials, such as crowns, fixed bridges, etc., because its low thermal conductivity can reduce thermal stimulation to the pulp.

Cardiovascular devices.
• Stents and pacemaker housings: Niobium and titanium alloys are suitable for making medical devices that come into contact with blood, such as heart stents and pacemaker housings, because of their non-toxicity and corrosion resistance.
• Guidewires and surgical instruments: Guidewires and other instruments used in cardiovascular surgery are also often made of niobium-titanium alloys to ensure safety and effectiveness.

Medical devices
• Surgical instruments: Niobium-titanium alloys are widely used in various surgical instruments, such as surgical blades, hemostats, scissors, etc. Their lightness and corrosion resistance make these instruments more ideal in clinical practice.
• Suture needles and filters: In fields such as cardiac surgery, niobium-titanium alloys are also used as suture needles and oxygen filters to ensure their biocompatibility and durability.
Niobium-titanium alloys have shown wide application potential in the medical field due to their excellent biocompatibility, high strength and low modulus.
