Stille Bone Chisel 25mm, 20cm (Maceven)

Clinical Application

Designed for controlled removal and shaping of cortical bone, this chisel is used for precision osteotomies, trimming bone edges, and creating flat surfaces in orthopedic, neurosurgical, ENT and maxillofacial procedures. The 25 mm cutting edge provides a broad bite for working on larger cortical surfaces while the 20 cm overall length gives tactile control and reach in deep or narrow operative fields. The instrument may be used freehand for delicate shaving or in conjunction with a surgical mallet for controlled osteotomes where appropriate.

Design & Configuration

The single-ended, beveled blade geometry concentrates force at the cutting edge for predictable bone entry and removal. A wider 25 mm blade delivers efficient material removal and surface contouring, reducing the number of passes required. The overall length balances leverage and surgeon tactile feedback, improving precision during hand-driven shaping or mallet-assisted osteotomies. The simple, robust profile is optimized for reliable seating against cortical surfaces and clean cutting action.
