What is Nitinol and Where is it Used
Why is it called Nitinol? where can it be found?
whether you're a healthcare professional or patient you could be curious to learn about the nitinol process and how it is used. Nitinol , a metal, is used in a myriad of medical applications, including orthopedic staples, medical devices and shape-memory alloys.
Form memory alloy
In contrast to other materials, shape-memory alloys have the ability to recall their previous shapes. This effect, which is two-way, can be created by applying the force of a machine or by heating. These alloys are known to have superior mechanical and wear resistance properties. These alloys are commonly used in the fabrication of orthopedic wires, valves, or medical devices.
Shape-memory alloys typically are created by using vacuum arc melting, casting or induction melting. These materials feature distinctive crystal structures that enable them to alter their shape and return them to their initial shape after being heated.
Shape memory alloys are widely recognized for their super-elasticity. They are used in applications such as orthopedics, robotics, and neurology. They also are used in the aerospace and automotive industries. The characteristics of shape-memory alloys allow for their widespread application in medical devices such as heart valves and stents. These materials also have applications in the chemical processing sector.
Shape-memory alloys are a mixture of nickel and titanium, and they are considered to be engineering materials. They are well-suited for the automotive industry and they have outstanding corrosion and wear resistance.
Various studies have been conducted to study the mechanical properties of Nitinol. These studies have demonstrated that the substance has mechanical hysteresis and shape-memory properties. These properties can help improve stent design.
Nitinol is a component in many different stents. These stents can vary in diameter and thickness, strut thickness and design. They can also manufactured using additive manufacturing technology. It allows manufacturers to design individual stents for specific patients medical conditions.
Recent studies have examined how Nitinol's stents' mechanical characteristics are affected. These studies use a combination of test techniques that are commonly used, like bench-top testing and finite element models. These techniques allow researchers to simulate complex loading conditions in-vivo. By using computational modeling, researchers can identify which design factors contribute to better performance.
One study measured the mechanical properties of six Nitinol stents. The stents are compared based on their stiffness, resistance to bending and axial compression. The stents ' diameters ranged between 5 and 8 mm. They had been supported using internal rods in compression.
The Orthopedic Staples
A variety of studies have explored the mechanical characteristics of nitinol used in orthopedic staples. A new generation of nitinol compression staples have proved successful in arthrodesis of the hindfoot.
Nitinol compression staples are utilized in bone grafting procedures and may slow the post-surgery recovery. However, this procedure might not be the ideal choice for patients with smaller bones. Small bones are more difficult to fuse, and any nonunion may lead to arthritis that develops early.
The nitinol memory compression staple is relatively new to the market for carpal bone fixation. The staple is made out of a superelastic TiNi alloy and permits natural compression as bone heals. It can be used to give adequate compression, and protects the proximal dorsal cartilage.
Compression staples are also used to stabilize subtalar joints as well as talonavicular Fusions. In addition, they are used to treat foot injuries in other conditions. They are also used to perform osteotomy procedures. They may not be stable enough to withstand small bone procedures and could disrupt osteotomies.
The latest generation of Nitinol compression staples been proven to be safe and effective for arthrodesis of the hindfoot. The study also explored the differentiators between single and double-staple constructions. Newer-generation Nitinol staples had high rates of radiographic union.
A couple of years ago, people in medical professionals came to comprehend the many benefits of the use of Nitinol used in devices that aid the medical field. The material is famous for its exceptional elasticity. This allows it to return to its original shape when under pressure. The properties of Nitinol also make it a perfect choice for orthopedic implants catheters and stents.
Nitinol's benefits for medical devices are significant as the material has opened up different markets for medical products. However, the characteristics of the material create numerous concerns. Understanding the risk factors that may be involved this material is crucial.
The Federal Drug Administration (FDA) recently issued a draft guideline for medical device manufacturers in the design and development of evaluate devices using Nitinol. It offers the most important guidelines for medical devices that contain Nitinol.
The guidance includes all medical devices that use nitinol. It describes the information manufacturers must include in their premarket submissions, such as information about the manufacturing, design, along with the tests of equipment. It also provides information on Nitinol's biocompatibility.
