Cortical Bone Collector
Advantages of the disposable
semicircular blade
• Maximum cutting efficiency
• Accelerates the harvesting time
•160° cutting area range
• Collects cortical bone shavings of appropriate
size and thickness for the graft integration
• Effective on any bone surface (plane, concave,
convex)
• Excellent control during the harvesting procedure
• No contamination due to the wear of the device
