During a craniotomy, which surgical instrument is typically used to retract brain tissue?

The Harrington retractor is specifically designed to gently and effectively retract brain tissue during a craniotomy. Its shape and design allow for optimal exposure of the surgical field while minimizing trauma to the delicate structures of the brain. The broad blade of the Harrington retractor provides ample surface area to hold back brain tissue, allowing the surgeon to work efficiently and safely.

In contrast, while the other options may be used in various types of surgeries, they are not ideal for retraction in neurosurgical procedures. The Deaver retractor, for example, is larger and often used for abdominal or deep tissue retraction, which may not provide the controlled and gentle retraction needed in a craniotomy. The Richardson retractor is commonly used in general surgeries and does not possess the same features that facilitate effective brain retraction. The Weitlaner retractor is a self-retaining device that is often employed in orthopedic or thoracic surgeries but lacks the specific design needed to retract brain tissue without risking injury.
