What type of instrument is characterized by having one or more openings used in surgery?

• A. A grasping forceps
• B. B fenestrated instruments
• C. C cutting scalpels
• D. D retractors

Answer: (B)

Fenestrated instruments are defined by their having one or more openings, which are designed to allow for specific surgical functions. The purpose of these openings is to facilitate airflow and fluid drainage, reduce tissue trauma, and minimize the risk of contamination during procedures. This design is especially useful in surgeries where visibility is critical, as it allows surgeons to see through the instrument while manipulating tissue or delivering energy.

Grasping forceps, cutting scalpels, and retractors do not have the same characteristic openings. Grasping forceps are used to hold or grasp tissues without openings, cutting scalpels are designed solely for incising tissue, and retractors are instruments used to hold back tissues, all of which lack the unique design feature found in fenestrated instruments. Therefore, fenestrated instruments stand out due to their specialized construction, making them essential in various surgical contexts.
