Engineered in India. Built for every operating room.
We build Ossa⁺ on a single conviction. How far your surgical skill goes should depend on your dedication, not on whether you can get hold of practice material.
From one question at the drilling bench.
Why does a trainee's first real mastoid surgery happen on a patient — or, if they're lucky, on one precious cadaver bone a year? Every alternative we found was either too crude to teach real judgement, or too expensive to practice on more than once.
So we built the material first. Ossa⁺ Composite™ took years of mixing, listening to surgeons before the first model ever shipped. Then we built models for the whole of ENT — not just the ear — and connected everything to KnowledgeBridge, so a model never arrives without a course to go with it.
Today our models are drilled at workshops, departments and conferences across India and beyond — and our balloon as well as larynx trainers are still the only ones of their kind anywhere in the world.

Every model is 3D printed with Ossa⁺ composite then hand cratted by skilled professional for maximum details
