Trephine Ejection Kit

Trephine Ejection Kit – Internally Cooled Two-Part Bone Extraction System
The Trephine Ejection Kit by Auana Surgical Industries, developed in collaboration with Professor Fouad Khoury, represents a revolutionary advancement in the field of oral and maxillofacial surgery. Designed with precision, innovation, and user efficiency in mind, this system enables safe, minimally invasive extraction of local bone cylinders for grafting and regeneration procedures.

Innovative Two-Part Trephine Design
At the core of this kit lies its two-part, internally cooled trephine system, engineered to ensure maximum safety and minimal thermal damage during bone harvesting. The internal cooling mechanism effectively prevents overheating, preserving the structural integrity and biological vitality of the bone tissue. Meanwhile, the removable trephine working parts allow for effortless retrieval of harvested bone cylinders — ensuring smooth, efficient workflow throughout surgical procedures.

Precision and Ease of Bone Cylinder Ejection
The Trephine Ejection Kit includes ejection instruments and needles that correspond precisely to the diameters of the trephine components. This perfect fit enables quick and clean ejection of the bone cylinders without deformation or contamination. Whether using the ejection sleeve, hand wheel, or dedicated ejection tools, clinicians can easily release the bone cores with unmatched control and accuracy.
