Solid-Phase Tessier Graft Calva Osteotome for High-Accuracy Skull Grafting
The Tessier Graft Calva Osteotome is a premier component of the cranio-maxillofacial toolkit, specifically engineered for the delicate shaving and collection of cortical bone from the calvarium. Functioning as a high-performance cranial shaver, this instrument features a specialized wide, slightly curved blade with protective lateral “wings” that prevent the edge from diving too deep into the diploë space. Adas Instruments ensures that each bone flap carver is balanced for center-point force transmission, allowing for the harvesting of thin, consistent bone laminae. We ship USA, Europe & worldwide via DHL, FedEx, and UPS to deliver German steel instruments that surgeons trust for their anatomical safety and mechanical resilience.
Why Craniofacial Specialists Choose Our Tessier Osteotome
- Guarded Blade Geometry: Features a specialized wide-body tip to act as a versatile cranial shaver, ensuring that the bone shaving remains strictly within the outer table.
- Enduro-Grip Stability: Specifically designed with a reinforced, weighted handle to function as a reliable bone flap carver, providing the surgeon with superior stability and anti-rotation control during the harvesting process.
- Curv-Flow Design: The anatomical curvature of the blade is optimized to follow the natural contour of the parietal bone, maximizing the surface area of the graft collected.
- Shield-Point Resilience: Forged from high-tempered surgical stainless steel to ensure the cutting edge remains sharp through repeated high-impact bone maneuvers.
Primary Surgical Applications
- Harvesting split-thickness calvarial bone grafts for orbital floor or nasal reconstruction.
- utilizing the cranial shaver function for smoothing irregular bone margins after a craniotomy.
- Performing efficient bone flap carver maneuvers during pediatric craniofacial remodeling.
- Collecting autologous bone shavings for filling small gaps in orthognathic surgery.
