Titanium alloys, as innovative materials and carrier substances, have demonstrated extensive potential in the field of healthcare. With remarkable corrosion resistance, high strength, low elastic modulus, fatigue resistance, and excellent biocompatibility, titanium alloys have become an ideal choice for limb implants, alternative functional materials, dentistry, and medical devices. This article explores the wide-ranging applications of titanium alloys in the medical field, highlighting their exceptional properties and discussing the ongoing research and development efforts to address existing challenges.
As the national economy flourishes, the demand for titanium alloys in the medical field continues to rise. Their excellent biological and mechanical properties make them highly promising for medical applications. However, compared to developed countries, China still faces certain gaps in the research, development, and application of titanium alloy materials, such as higher elastic modulus, poor surface activity, inadequate wear resistance, and corrosion resistance. To address these issues, China should intensify research efforts, prioritize innovation, and develop new titanium alloys with superior overall performance to meet the ever-growing demands in the healthcare sector.
Titanium alloys have emerged prominently in the realm of medical devices. As a third-generation surgical instrument, medical devices made from titanium alloys possess characteristics such as lightweight, excellent corrosion resistance, non-toxicity, and appropriate elasticity, making them well-suited for delicate microsurgery. Furthermore, the low reflectivity of titanium alloys makes them ideal for operation under surgical lamps. The range of medical devices made from titanium alloys is vast and includes surgical knives, forceps, tweezers, thoracic expanders, suturing needles, and suturing threads. Titanium wires, for instance, used as surgical sutures, offer advantages such as minimal tissue reaction and excellent torsional resistance, effectively promoting wound healing.
