Which of the following is a powered cutting instrument commonly used in surgical procedures?

• A. Bone reamer
• B. Scalpel
• C. Forceps
• D. Tweezers

Answer: (A)

The correct answer is the bone reamer. Bone reamers are specialized powered cutting instruments used primarily in orthopedic surgeries to prepare bone for the insertion of implants, such as nails or screws. They allow for precise removal of bone material and are designed to accommodate the specific dimensions required for the surgical procedure being performed.

In contrast, scalpels are manual instruments with a sharp blade used for making incisions, but they do not fall under the category of powered devices. Forceps and tweezers are both hand-held instruments used for grasping or manipulating tissues and materials during a surgical procedure, but again, neither of these is powered or designed for cutting. The unique function of the bone reamer makes it essential for certain surgical techniques, particularly when dealing with hard tissue.
