Study Notes
Gold Plating on Instruments
- Tungsten carbide is introduced in gold plating to increase durability and resistance to wear.
Surgical Instruments
- 4" delicate scissors and forceps are primarily used for dissection, suturing, and other intricate procedures.
- Retractors are specifically designed to access and expose wounds during procedures.
Bone Files and Rasps
- The primary function of bone files and rasps is to remove bone tissue and shape bone during surgical procedures.
Instrument End-Users and FDA Regulations
- According to CDC mandates, instrument end-users are required to follow proper cleaning, disinfection, and sterilization procedures.
- The US FDA emphasizes the importance of proper sterilization and reprocessing of reusable medical devices.
Instrument Grades
- Physician Grade instruments are distinguished from other grades by their high-quality materials and craftsmanship.
- Sterile disposable Floor Grade instruments are characterized by their single-use design and low cost.
Stainless Steel Properties
- The 440 Series stainless steel is known for its extreme corrosion resistance and non-magnetic properties.
- The 400 Series stainless steel is distinguished by its hardness and corrosion resistance.
- The 420 Series stainless steel is suitable for precise cutting edges due to its hardness and sharpness.
- The 410 Series stainless steel is distinguished from the 420 Series by its lower carbon content and lower hardness.
FDA Guidance on Reprocessing
- The main emphasis of the FDA's final guidance on reprocessing medical devices is proper cleaning, disinfection, and sterilization to prevent patient infection.
Disposable Instruments
- Disposable instruments are considered an ideal alternative to reusable ones due to reduced risk of cross-contamination and patient infection.
- A significant advantage of single-use instruments is the elimination of reprocessing costs and reduced risk of patient infection.
- Single-use instruments contribute to reducing instrument reprocessing costs by eliminating the need for cleaning, disinfection, and sterilization.
