Medical Small Diameter Titanium Tube

Medical small diameter titanium tube has been used for decades in the pharmaceutical industry, surgical instruments, human implants and other fields and the world, and has achieved great success. Medical grade titanium tube is used in medical devices, prostheses or adjuvant therapeutic devices, characterized by an elastic modulus close to that of natural bone.

When the average person thinks of "oxidation," they think of rust: rusty cars, rusty nails, and so on. With rusty pieces of steel, the oxidation damages the material, penetrating deep into it, and eventually destroying it entirely.
Rust is only one example of oxidation. Some materials, such as aluminum and titanium alloys, oxidize quickly. In the case of titanium, however, instead of the oxidation acting as a destructive layer, the oxide on the surface forms a protective barrier, preventing the oxygen from penetrating deeper into the bulk of the material. The titanium oxide that forms as a thin film on the surface of titanium alloys is a hard, chemically resistant material, which acts as a thin protective layer around the metal.

What's the difference between rust and the protective oxide layer? Rust tends to not form a cohesive layer on the surface. When steel rusts, the oxide layer expands and is not bonded well with the layer beneath and flakes outward, exposing fresh steel for an oxide attack. This process continues until the steel has been completely reacted with the oxygen and corroded away.

With titanium alloys, the oxide maintains the existing cohesive bonding to the layers under the oxide layer, meaning it does not flake off and oxygen can not reach the un-oxidized metal beneath it. Once the surface is completely coated with oxide, the reaction has been run to completion, and no further oxidation can occur.

In the harsh environment of the human body, any implant is subject to corrosion. The human body is practically a saltwater bath of varying pH, which wreaks havoc on most materials. Plain carbon steel would quickly rust away, destroying the device and contaminating the body with rust particles. In contrast, titanium alloy parts resist the constant chemical attack of the human body; the device does not deteriorate or generate rust particles that can cause health problems.

Should the thin oxide layer get damaged, the speed at which titanium alloys oxidize means that the oxide layer will quickly regrow, even while immersed in the human body. While most implants will never get physically damaged in this manner, some wear surfaces, such as the contacts on replacement joints, could under extreme conditions.

World population is getting older. We now live in a very active life and desire to be living longer. Injuries caused by hard sports, road traffic and other accidents are everywhere. Obviously, the demand of artificial joint continues to grow. Titanium and its alloys have been commonly used to fabricate implant devices such as: artificial hip joints, artificial knee joints, bone plates, screws for fracture fixation, cardiac valve prostheses, pacemakers and artificial hearts. Each year more than 100 million patients in the world received replacement therapy and more than 1,000 tones of titanium being implanted into patients' body worldwide.

Mechanically, these metal implants must be formed to certain shape and maintain functions during the usage period. Our daily activities include bending, twisting, squeezing and muscle contraction. These artificial parts must not be deteriorated when subjected to fatigue, abrasion and impact loads. Titanium has 50% less weight and 20% higher strength/density ratio of stainless steel. It is lighter and stronger. When implant inside human body, it will reduce body loads. Patients will feel more flexible and active. There will be stress between artificial part and human body. The so-called interface stress is caused by mismatch of elastic modulus. From table 1, we can see that titanium has lowest elastic modulus among these three materials. The mechanical compatibility of titanium implant and human bone is much better.

Physiologically, the body rejects foreign parts. When use stainless steel and co-alloy as biomaterials, clinical inflammation, redness, and itching often occur after implant operation. Titanium and titanium alloys are well known as biologically inert metal materials. In the immersion environment of human blood they have excellent corrosion resistance. It resists human blood and cell tissue very well, ensuring good compatibility. There is almost no pollution and allergic reactions, which greatly improves the patients' recovery. This is the basis for the widespread applications of titanium.

In general, commercially pure titanium (Cp Ti) is considered as the best candidate because pure titanium has best biocompatibility. But Ti-6Al-7Nb, Ti-13Nb-13Zr, Ti-12Mo-6Zr and Ti-6Al-4V ELI alloy are also widely used in medical implants.

You'd be surprised how titanium is used in human life! As a transition metal, titanium boasts several desirable properties, including high strength, low density, corrosion resistance and thermal resistance, which makes it so suitable for various industrial applications!

Titanium was first discovered by the aerospace industry to create reliable aircraft components but today, there are countless other ways that the titanium rod can be used. The fact that the metal is non-toxic makes it ideal for the medical industry when it comes to joining human bone, either to repair fractures or breaks.

Titanium Joint Replacements.
As a result of titanium being biocompatible, it promotes the joining of tissue and bone without the need for extra adhesive. Another reason why titanium is a preferred metal is to do with the fact that it can resist high impacts and prevent breakage.

Orthopaedic Implants.
1940 saw the development of the titanium plate. Titanium gained popularity with the dental industry before it was introduced to the orthopaedic department in 1950. Titanium is used today for inner body devices (i.E. Heart pacemakers), internal fixation, prosthetics and medical instruments, which makes it one of the most popular metals used in the medical field.

Titanium Dental Implants.
With dental implants, screws that are made from titanium can easily be inserted into the jaw. These screws act as the root of the tooth and blend naturally into the bone. When the implant is set, an artificial tooth can then be inserted- making titanium an easy material to work with.

Titanium Alloys Used In Medicine.
As a pure metal, titanium has a low density to high strength ratio. It also offers a high level of corrosion resistance and is a non-toxic or magnetic transition metal. The elasticity and thermal expansion of the titanium bars offers resemblance to human bone, making it perfect for joint replacements!

Osseointegration.
The term "osseointegration" simply refers to the bone's ability to attach to a metal. As an implant is inserted into a bone, the surrounding tissue becomes very sensitive. Once the implant is exposed to oxygen, a protective oxide layer forms naturally to protect the bone.
The titanium plate is used by the medical field as a result of its metallic properties. Offering resistance to corrosion, tissue and fluid, a titanium tube is accepted by the human body and a high force is required to break it.

Medical Instruments And Devices.
Surgical instruments tend to be made from titanium because they need to resist bacteria. An example of instruments that are used by medical professionals includes surgical forceps and drills which are made from titanium.
