Leica Microsystems' next-generation surgical microscope

Opening up new dimensions in ergonomics and mobility — in close cooperation with leading neurosurgeons, Leica designed a new swivel arm for its M525 OH4 surgical microscope that offers 36% more reach than comparable instruments.

The newly designed swivel arm grants surgeons and even the whole operating team considerably more room to manoeuvre. During an operation, the assistant has enough room to go between the stand and the surgeon, while a long, flexible monitor arm can be adjusted to a viewing position for the entire team.
Further advantages of the new Leica M525 OH4 are its precise, smooth and balanced movement with far lower vibration and an extremely short start time. The Leica OptimaChrome optics and a 2 x 300 watt xenon system with an automatic lamp changer provide surgeons a clear, sharply focused image on the field of operation and guaranteed stable illumination, even in the case that one lamp fails. The AutoIris technique eliminates undesired stray light, preventing the complication of overheating tissue outside the field of view. The BrightCare feature regulates the light to the optimum intensity automatically when reducing the working distance. The integrated and FDA-approved FL800 fluorescence system combines an excitation light system with an ICG fluorochrome and near infrared camera. During the operation, surgeons could now visualize vascular blood flow directly in the surgical microscope or on a monitor.

Leica Microsystems designed its M525 OH4 surgical microscope as an open architecture. The system can be easily adapted to next-generation standards.
