What is an obturator used for in surgical procedures?

• A. A tool used for measuring surgical depth
• B. A headpiece for surgical instruments
• C. A removable part used during insertion of instruments
• D. A device for suturing wounds

Answer: (C)

The obturator is specifically designed to aid in the insertion of various surgical instruments, particularly in procedures requiring access to body cavities or spaces. It is commonly used to facilitate the introduction of cannulas or other hollow instruments. By providing a smooth leading edge, the obturator helps reduce trauma to surrounding tissues during the insertion process, making it an essential tool in various surgical settings.

The other options do not accurately describe the function of an obturator. Measuring surgical depth pertains to tools designed for gauging the extent of incisions or cavity explorations, while a headpiece would relate to the physical design or attachment of instruments, and suturing wounds involves different instruments specifically designed for that purpose. Thus, the obturator's role as a removable part during the insertion of instruments is crucial for maintaining efficacy and safety in surgical procedures.
