Who We Are
Gyder Surgical is an Australian MedTech company specializing in intuitive, non-invasive orthopaedic navigation products.
We believe that every patient should have access to accurate and precise surgery, no matter where they are. We are building products that work in a wide variety of care settings – Ambulatory / Outpatient Surgery Centers or large ORs in hospitals.
We believe that the best solutions minimize complexity and do not require surgeons to significantly change their practice. The GYDER® Hip Navigation System, our first product, is designed to assist surgeons accurately place the acetabular cup during hip surgery.
The Origin of Gyder Surgical
Gyder Surgical was formed by Bob Lye to develop and commercialise the GYDER®System.
Bob started his career with QANTAS where he trained in aircraft instrument systems. In the 1990s Bob left QANTAS and acquired MAC Surgical, a company specialising in the orthopaedic instruments for leading manufacturers. As Bob began to work closely with surgeons he became aware of their challenge when positioning the acetabular cup in the pelvis during hip replacement procedures. Bob’s background gave him a unique perspective on this problem and he applied modern aeronautical navigation techniques to the acetabular cup challenge. This led to invention of the GYDER® System.
