Study Notes
FDA Guidance on Reprocessing Reusable Medical Devices
- The FDA's final guidance on reprocessing reusable medical devices emphasizes the importance of proper reprocessing to ensure device safety.
- Instrument reprocessing is affected by the material used to make the device.
Ideal Instrument Materials
- Disposable instruments are considered ideal for non-critical applications due to their convenience, low cost, and reduced risk of infection.
- The first surgical instruments were made from materials such as wood, bone, and stone.
- The advent of stainless steel surgical instruments eliminated the need for crafting instruments from wood or decorative materials due to their durability and resistance to corrosion.
Historical Development of Surgical Instruments
- The discovery of iron and steel during the Industrial Revolution (18th-19th centuries) moved surgical instruments into modernity.
- Abu al-Qasim Al-Zahrawi made the greatest advancements in surgical instruments during the Islamic Golden Age (8th-13th centuries).
- The movement towards disposable instruments was initiated by concerns about hospital-acquired infections and the need for improved patient safety.
Properties of Stainless Steel
- Stainless steel is ideally suited for the surgical suite due to its corrosion resistance, durability, and ability to be sterilized.
- The partial solution to the corrosion of steel instruments at the end of the 1800s was the development of stainless steel.
- With proper care and handling, stainless steel instruments can last for many years, often 10-15 years or more.
Key Figures
- The father of modern medicine is Hippocrates.
Explore the differences between reusable and disposable surgical instruments, and their impact on patient outcomes and healthcare practices. Ideal for professionals in the surgical, central service supply, instrument manufacturing, and healthcare fields.
