In addition, it also describes passivation as “the chemical treatment of stainless steel with a mild oxidant, such as a nitric acid solution, for the purpose of enhancing the spontaneous formation of the protective passive film.”

In layman’s terms, the passivation process removes “free iron” contamination left behind on the surface of the stainless steel as a result of machining and fabricating processes. These contaminants are potential corrosion sites which, if not removed, result in premature corrosion and ultimately result in deterioration of the component.

Abdominal access systems, commonly referred to as “trocars,” have 2 components:

• A removable inner obturator or “trocar,” used to facilitate insertion
• An outer cannula or “port,” which remains in place to allow passage of instruments and insufflation.

The large number of currently available trocar designs can be classified into 2 categories:

• Cutting trocars – Cutting trocars incorporate a sharp metal or plastic blade that cuts through tissue layers as force is applied. The main advantage of this type is easy insertion through the abdominal well.
• Dilating trocars - Dilating systems typically use a trocar with a tip that bluntly separates and dilates tissue as force is applied. Dialating Trocars, the more recent access systems have used noncutting trocars. Designed to eliminate the blade inherent to cutting systems, a  blunt tip or expandable sheath is used to dilate or separate tissues as the trocar penetrates the abdominal wall.

 Instruments Care and Handling

• Medical Tools Instruments last for years with proper care and handling. Please use these guidelines for all stainless steel instruments.
• Brand new instruments should be cleaned prior to first sterilization.
• Contaminated instruments should be processed as soon as possible.
• Stubborn protein particles can be removed with a scrub brush. Never use steel wool, abrasives or an acid rinse.
• Open joints on instruments prior to preparation
• Do not use multipurpose detergents to wash or soak instruments. Instead, use a low-suds detergent specifically designed for instruments. The pH should never be higher than 8. When using ultrasonic, a detergent with a pH of 6, 7 or 8.
• Lubrication is vital to a long instrument life.
• Avoid silicone lubricants because they tend to build up and mix with debris to clog moving parts, which becomes almost impossible to remove. Debris buildup can have a “rust-like” appearance.
• Rinse your cleaned instruments

Surgical Retractors

A retractor is a surgical instrument that is used to hold back underlying organs and tissues, so that body parts under the incision may be accessed without any fear of damage to the organs lying at the above levels. Surgical retractors have a wide variety and retractors come under various shapes, sizes and strength.

Importance of Surgical Retractors

During the dissection/inspection, a surgeon needs an exposure best as possible while inflicting a minimum of trauma to the surrounding tissue. The handles of the retractor may be hook-shaped, notched, or ring-shaped to give the holder a firm grip without tiring. The blades of the retractors are at a right angle to the shaft. The blades can be smooth, raked, or hooked.

Materials

Surgical retractors require a very high-grade stainless steel as they hold internal organs during an operation. A common material used in the making of retractors is superior grade stainless steel. Stainless

The use of instrument cassettes facilitates instrument processing and can greatly enhance the organization of instruments. It also keeps all the instruments for a specific procedure together from the chairside procedure through cleaning, rinsing, drying, and sterilization. Following completion of dental treatment, instruments can be arranged in the cassette, transported to the instrument processing area, and placed in the ultrasonic cleaner as a unit. The cassette also can be rinsed and dried in this manner. In addition, a cassette system can reduce the direct handling of potentially contaminated instruments before sterilization. Furthermore, instruments prearranged in the cassette will require less handling following sterilization.

Perforated cassettes are preferable since completely solid containers will not allow steam or chemical vapor to reach the contents and allow sterilization to occur. Cassettes
