The Bayonet Kerrison Punch from INSTROFINE is a premium surgical instrument designed for precise bone removal during spinal and neurosurgical procedures. Its bayonet-style offset shaft improves the surgeon’s line of sight by keeping the handle away from the operative field, providing enhanced visualization and greater control during delicate procedures.

Featuring a 40° upward jaw, an integrated bone ejector, and a durable black titanium-coated finish, this instrument combines precision, efficiency, and long-lasting performance. The precision-ground cutting jaw delivers smooth and controlled bone resection, while the bone ejector efficiently clears bone fragments from the jaw, minimizing interruptions during surgery.

Manufactured from premium surgical-grade stainless steel, the Bayonet Kerrison Punch is engineered for superior durability, corrosion resistance, and repeated sterilization. The ergonomic spring-action handle reduces hand fatigue while providing smooth and responsive operation throughout demanding procedures.
