Large oscillating blades are specialized surgical instruments designed for medical procedures that require precise cutting with an oscillating or reciprocating motion. The term "large" signifies that these blades are larger in size compared to standard oscillating blades, making them suitable for procedures that involve more substantial cutting or dissection. The "oscillating" motion refers to a back-and-forth movement, and these blades are specifically designed to perform cutting or dissection tasks with this type of motion.
