Using an operation microscope enabled the surgeon to minimize the acess to the disc by magnifying the view at the operation field. Instead of removing the whole lamina arche only a small portion is abraded.
The skin inzision is reduced from 10 cm to approximatly 3 cm and special spreaders, punches and new designed bajonett shaped surgical instruments completed the device to an operation set system for dorsal Mirodiscectomy.
The Operation Microscope has been developed first for eye surgery bei Zeiss in 1953. First surgical microscope OPMI 1 - developed in cooperation with leading surgeons: Prof. Dr. Horst Wullstein (ENT) and Prof. Dr. Heinrich Harms (ophthalmology).
Operation Microscope 1970 Modern Operation Microscope
Surgical Microscope of 1970 with 5x zoom system that allows continuous magnification change over the entire region. In 1975 the operation microscope has been modified for use in Neurosurgery and became the base for microdiscectomy used by Caspar and Yasargil for spinal treatment. Technical Progress lead to advanced modern Operation Microscopes for better resolution, sharpness and magnification.
Microdiscectomy became "Gold Standard" in herniated disk treatment but endoscopic procedures become more and more important because of a less invasive access.
