Which Alloy is Best for My Surgical Instruments?

 

Stainless Steel (Inox)

Our standard line of instruments is manufactured of highest quality materials. They are made of austenitic 316 steel commonly known as “surgical steel” or “marine grade steel.” Stainless steel, also known as Inox (from the French word "inoxydable"), is highly corrosion resistant and it is a common choice of material for biomedical implants or body piercing jewelry. It is in compliance with ASTM F138. This WPI line is an excellent alternative to German surgical instruments. The high-quality, corrosion-resistant instruments are available at a fraction of the price of German surgical instruments, which are also manufactured from the same type of steel. Stainless steel is well suited for medical purposes, because this stainless steel, magnetic alloy has excellent corrosion resistance and good salt resistance. Temperature resistant up to 400°C, it can be autoclaved at 180°C. Almost as strong as carbon steel, Inox is an excellent general-purpose alloy for surgical instruments

Titanium

100% anti-magnetic, corrosion-resistant, lightweight and strong, Titanium alloy is ideal for biological and medical applications. Titanium has the tensile strength of carbon steel and is completely resistant to corrosion from nitric acid, chloride, saltwater, and industrial and organic chemicals. Titanium is more flexible and 40% lighter than Inox. When heated or cooled, the dimensions of Titanium alloy change less than half of what stainless steel alloys will, making Titanium surgical instruments much more durable. Titanium is stain-free and temperature resistant up to 430°C. Titanium tools are the premium choice for corrosive environments or MRI applications.

Dumoxel®

Developed by Dumont Tools, Dumoxel is highly resistant to sulphuric environments, hydrochloric acid, mineral and organic acids. Extremely flexible, Dumoxel is 95% antimagnetic and stain resistant. Temperature resistant up to 400°C, it can be autoclaved at 270°C. Dumoxel is the most popular Dumont alloy for tools.

Dumostar®

Patented by Dumont Tools, Dumostar is more elastic and more corrosion-resistant than the best stainless steel. It is resistant to mineral and organic acids and salt corrosion. Dumostar is 100% anti-magnetic and temperature resistant up to 500°C. Dumostar is the most cost-effective and appropriate alloy for laboratory tools.

Antimagnetic Stainless Steel - With good corrosion resistance, this alloy is 80% antimagnetic. Temperature resistant up to 400°C, it can be autoclaved at 270°C. Antimagnetic is not quite as hard as Inox.

Black Titanium Coated Surgical Instruments

WPI black coated surgical instruments have a titanium nitride (TiN) shell, which is an extremely had ceramic material. Non-reflective, these instruments are ideal when you are working under bright lights or a microscope. See why this coating is beneficial for surgical instruments.

Our black instruments are coated with titanium nitride (TiN), an extremely hard ceramic material. The TiN coating hardens and protects the cutting edge. Ceramic coated anti-reflective instruments are perfect for microscopy and microsurgical applications. Coating surgical instruments with a black ceramic adds a thin layer to the metal instrument, making the instrument harder and giving you greater precision. This anti-glare surface minimizes reflections off the surface of your instruments. The incredibly smooth coating improves the instruments’ resistance to corrosion and minimizes friction. The ceramic coating is virtually impenetrable, because the raw material is bonded to the instrument both physically and chemically. These instruments are much more resilient to the pressure of daily use and chemical processing. Coated instruments last considerably longer.

Surgical Instrument Care and Handling

RINSING Immediately after use, rinse surgical and dental instruments under warm or cool running water to remove all blood, body fluids and tissue. Dried soils may damage the surgical and dental instrument surface and make cleaning very difficult. Do not use hot water as this will coagulate proteinous substances. CLEANING TECHNIQUES Time, temperature, and agitation play important roles in the cleaning process. Time  — the efficiency of cleaning chemicals is often time dependant Temperature  — higher temperature cleaning solutions result in better cleaning Agitation  — whether manual or ultrasonic, it is helpful in loosening the soil on the surface of the instrument Automatic Washer Sterilizers Follow manufacturer’s recommendations. Lubricate surgical and dental instruments after last rinse cycle and before sterilization cycle. Manual Cleaning 1. Use stiff plastic cleaning brushes. Do not use steel wool or wire brushes. 2. Use only neutral pH detergents. If not rinsed properly, low pH

Benefits of Black Coated Instruments

  Benefits of black coated surgical instruments Black coated  surgical instruments  are not only visually more attractive than the stainless-steel ones, there are several other benefits as provided below: -        Non reflective surface reduces eye-fatigue   -        Has prolonged life -        Up to 10 times harder than stainless steel -        60% lower wear rate than stainless steel -        Corrosion resistant due to oxidized aluminum coating -        Anti-allergic due to the absence of Chromium and Nickel coating  -        Easy to clean Making of the black coating instruments The black coatings are created by applying a layer of Titanium Aluminum Nitrate (TiAIN) to the instrument, using an environmentally friendly Physical Vapor Deposition (PVD) process. In this process Titanium and Aluminum are magnetron-sputtered onto the substrate in a vacuum chamber. The metal particles of the target are transformed into vapor phase, they interact with Nitrogen ions and get deposited onto the
