Surgical knives designed for cutting and/or dissecting tumors during microsurgical procedures. These knives usually consist of manual, needle-like handheld instruments, usually with a straight tubular handle and a shaft with a straight or curved cutting blade (e.g., ovoid, round) at its distal tip. Microsurgery tumor knives are mainly used in neurosurgical procedures; dedicated knives intended for dissection of particular tumors (e.g., acoustic neurinomas, also known as schwannomas) are also available.
