Industry Situation Of The Metallic Material Tantalum

1. High Clinical Demand and Large Market Size Preparation of biocompatible bony scaffolds has always been one of the hot topics of research in the medical field, and there are no less than 3 million cases of medical human bone implantation in China every year, with the price of tens of thousands or even more than 100,000 yuan per case. According to EvaluateMedTech, orthopedic-related medical devices had global sales of $36.5 billion in 2017 and will reach $47.1 billion in 2024, with a compound annual growth rate of 3.7%. And according to the Southern Institute of Pharmaceutical Economics, the domestic orthopedic implant consumables market size was 25.8 billion yuan in 2018, with a CAGR of 17.1% from 2014-2018, and it is expected to reach 50.5 billion yuan by 2023, with a CAGR of 14.2% from 2019-2023, a growth rate that far exceeds that of the global market with great potential.2. 2. Current orthopedic metal implantable materials for medical human body The choice of bone implant materials, the earlier application of the material is stainless steel, nickel-chromium alloy, nickel-titanium alloy, the last 2 or 3 years the trend is TC4 titanium alloy, these materials contain nickel, chromium, or aluminum, vanadium and other harmful elements, and because of its elasticity modulus exceeds the human skeleton is too much, the material and the human body affinity is low, prone to the occurrence of the "bone does not stick" phenomenon. Phenomenon. Medical experts and the market urgently need new non-toxic and harmless materials with good human affinity to improve the current situation.3. Multiple implant sizes, different clinical application scenariosPorous tantalum has many advantages, such as: (1) Perfectly integrates with the host bone interface: compared to the most commonly used titanium, tantalum is more biocompatible and has a stronger osseointegration ability. (2) Unique bionic trabecular structure: Tantalum's modulus of elasticity is closer to that of bone tissue, making it more suitable for bionic trabecular structure than other metals. (3) Inducing rapid growth of bone and blood vessels: it can promote the rapid growth of bone and blood vessel tissues into the pores of porous tantalum, and its highly porous and supportive structure provides a wide range of space for bone to grow into and form a good biological fixation, which can effectively solve the problem of exothermic bone cement, and its effect on the surrounding tissues, which is a great clinical progress.
