Types of Metals Used in Surgical Instruments

Surgical instruments

We all are well aware of the famous fact “quality input = quality output”. This basic principle also implies for producing quality surgical instruments. There are many considerations when it comes to selecting the right material to use in the surgical instrument and dental instruments industry, which are sometimes referred to as medical instruments. Selecting an incorrect material may lead to serious consequences. Many countries have set stringent regulations, which need to comply before someone markets or imports in that country.
This article is about the minerals that are being used in surgical instruments manufacturing and the reasons of their usage.
The most commonly used minerals for surgical instruments are:

Stainless steel

The metals being used in surgical instruments must comply to set standards.
First, the metal must be relatively flexible so it is often formed without causing defects, but not too soft because it must retain its shape once manufactured. Counting on the tool, the metal used must also be flexible, as many of the surgical instruments are long and thin, for example, consider the shape of Curettes, scalpels, forceps, tongs, scissors.

The metal surface must be harsh and need a final touch of satin, therefore the tools are easy to wash and don’t contain bacteria that way infections could be prevented from spreading. The metal must be inert with the physical body, so it may not cause any contamination of the metal when it is used internally.

Stainless steel

Stainless Steel or Chromium Steel is used for over 80% of the Conventional surgical instruments produced worldwide in both types, the single-use, and re-usable instruments. The most commonly used SS are austenitic 316 stainless and martensitic 440 and 420 stainless. Surgical steel is the most corrosion-resistant form of stainless steel.

Titanium in surgical instruments

Titanium is right for both surgical instruments and implants because it is biocompatible and features a self-quality that blends well with human bones. For this reason, this metal has become the favorite for bone rods, pins, planks and dental implants.
In general, titanium may be a strong and sturdy metal that has become a standard material used for all types of medical purposes.
The metal is immune to body fluids and is additionally highly resistant to corrosion, so it is often utilized in surgery without causing harmful effects. For equivalent reasons, they’re also utilized in implants and bone replacement materials within the prosthesis.
Its usability is additionally a beautiful feature because it is often pulled into a skinny wire, while its readability allows it to be easily manufactured in several forms.

Platinum and Palladium

Platinum and Palladium are precious metals and expensive. Some unique properties make them the choice of metal in some limited number of surgical applications.
We can achieve any shape as well as precision that we need to form out of these metals, as they are flexible. Both platinum and palladium are corrosion resistant and inactive so that they are not reported as to cause problems when connecting to the body or internal organs.
