What instrument is specifically used for cutting during a craniotomy?

The instrument specifically used for cutting during a craniotomy is a craniotome. This specialized tool is designed for performing precise cuts in the skull, allowing for the removal of a section of bone to access the brain. The craniotome is engineered with a focus on safety and efficiency, often featuring a circular saw or oscillating mechanism to minimize trauma to surrounding tissues.

While a scalpel is a common surgical instrument used for making incisions in various tissues, it is not specifically tailored for the unique requirements of cranial surgery. Electrocautery is utilized for cutting and coagulating tissues using electrical current, but it is not the primary instrument for creating openings in the skull. Surgical scissors are intended for cutting soft tissues and sutures rather than bone. Thus, the craniotome is the appropriate choice due to its specialized design for craniotomy procedures.
