IAHCSMM CRCST Practice Test – Chapter 11 Complex Surgical Instruments

Last Updated on June 25, 2024

IAHCSMM CRCST Practice Test – Chapter 11 Complex Surgical Instruments. The chapter’s learning objectives encompass knowledge and understanding of processing powered surgical instruments, concerns, and procedures for handling endoscopic instruments, infection prevention concerns related to endoscopes and loaner instrumentation, and basic protocols for each step in the loaner instrumentation process.

This chapter introduces the evolution of surgical instruments, from simple devices to the complex ones in use today. It highlights explicitly powered surgical instruments and endoscopes requiring special handling and care. The chapter emphasizes the need for meticulous cleaning, detailed inspection, and correct packaging and sterilization of these instruments.

It also discusses powered surgical instruments, which have transformed surgery procedures, making them safer and faster. Their design complexity ranges from drills on tiny ear bones to drills and saws on large leg bones.

Three primary power sources for these instruments are discussed: electricity, compressed gas (pneumatic), and batteries. The chapter provides guidelines for proper handling, cleaning, and maintenance for each power source.

The chapter highlights that these complex instruments represent a significant financial investment for hospitals, hence the need for careful handling. Lastly, it discusses CS technicians’ challenges in keeping up with new and evolving instruments and their specific processing requirements.
