Medical Tantalum Beads

 

Tantalum metal has the characteristics of high strength, good plasticity and ductility, high chemical stability, corrosion resistance, high mechanical reliability, good fatigue resistance, and high affinity to biological tissues. It is often used as a high-performance biomedical metal material to manufacture high-end implantable interventional devices. Widely used in orthopedics, craniomaxillofacial, oral and general surgery and other fields. For example, pure tantalum is used to manufacture hip, knee, shoulder, elbow, ankle, hand and foot joint implants, intervertebral fusion devices and artificial vertebral spinal implants, femoral head necrosis reconstruction rods, bone fillers, artificial Skull patches, bone plates, dental implants and implant-anchored oral implants, dental tools, anti-corrosion coatings for vascular stents, surgical sutures, contrast agents, imaging positioning posts and hemostatic clips, etc.

Medical tantalum beads are a special material used in the medical field and have the following characteristics:

High biocompatibility: Medical tantalum beads have excellent biocompatibility, which means that they will not cause obvious rejection or allergic reactions in the human body. This makes medical tantalum beads an ideal choice for use in medical devices or implants that come into contact with human tissue.

Corrosion resistance and wear resistance: Tantalum is a metal with excellent corrosion resistance and wear resistance, which makes medical tantalum beads widely used in medical equipment. It can exist stably in the body for a long time without being affected by corrosion or wear.

High Density: Medical tantalum beads have a high density, which makes them valuable in certain medical applications. For example, it can be used in radiation therapy to achieve more precise treatment effects by adjusting the number and layout of tantalum beads.

Ease of Processing: Medical tantalum beads can be easily processed and shaped to meet the needs of various medical devices. It can be cut, drilled or made into different shaped parts to make it more adaptable and functional.

Non-magnetic: Tantalum is a non-magnetic material, which makes medical tantalum beads ideal for use in magnetic resonance examinations such as nuclear magnetic resonance (NMR) imaging. Because it is non-magnetic, it does not interfere with magnetic fields and produce artifacts that could affect inspection results.

As a biomedical material, tantalum metal needs to be implanted into the human body. In order to ensure the life, health and safety of patients, it needs to meet very strict standards and classifications.

 

X-ray stereophotogrammetry analysis (RSA) is a technology that uses X-rays to accurately measure the three-dimensional position of objects. Traditional RSA is an invasive technology that requires the implantation of a certain number of tantalum balls as markers in the bone tissue and around the artificial joint prosthesis. The tantalum implants are round and of a tiny size.

The most traditional use of RSA is to monitor early loosening following the implantation of an artificial joint. That is, RSA pictures are taken immediately after artificial joint replacement as a reference image, and RSA pictures are taken again after surgery and compared with the reference image. By simply comparing the relative displacement of the tantalum ball projection in the X-rays before and after the measurement, the relative displacement between the artificial joint and the bone tissue can be known, and further infer whether the artificial joint is loose or not. If the tantalum ball around the artificial joint is stable and has no relative displacement with the artificial joint, and the tantalum ball implanted in human bone tissue is also stable and does not move, it can be inferred that the artificial joint is not loose.

Tantalum has good plasticity and is easy to be processed plastically. Various profiles can be produced using conventional processing techniques (extrusion, forging, rolling and drawing). Tantalum smelting ingots all have a coarse grain structure, and their grains must first be crushed by extrusion or hot forging (initial processing) before they can be further processed into materials. Pure tantalum can be forged and bloomed at room temperature. The blooming temperature of tantalum alloys is generally 100-12000. During the working process, the surface of the tantalum alloy is oxidized to form loose oxides, which can penetrate into the alloy matrix to form a hard penetration layer, causing cracks during processing. Therefore, efforts should be made to protect the metal surface from oxidation during the entire processing process. Currently, tantalum billet protection methods include salt bath heating, coating, encapsulation, inert gas protection, etc.
