M525 OH4 Surgical Microscope Solution for Precision Neurosurgery

OH4 stand designed by Mitaka

M525 OH4 Leica Microsystems stands for excellence in optics. Outstanding contrast, brilliance, sharpness, resolution, color fidelity, and precision are hallmarks of surgical microscopes. The OH4 stand, designed by Mitaka, not only complements the M525 optics, but also improves the overall microsurgical experience with superior movement, innovative illumination, and userfriendly features. Designed and manufactured using superior materials and the highest quality standards, the premium M525 OH4 miscroscope is built for long service life and outstanding reliability.

OPTICAL EXCELLENCE By integrating new glass, coatings, and design parameters, Leica’s OptiChrome technology delivers the extra working distance, depth of focus, and light intensity needed for precision microsurgery. It forms the basis for the premium optical system. M525 optics deliver the following out tanding benefits s compared to previous systems: • Longer • Deeper • Brighter • Sharper • Smarter 32% extended working distance to 470 mm 30% increased depth of focus at same magnification 30% more light intensity Higher contrast and crisper, sharper images AutoIris magnification-controlled il

ADVANCED ILLUMINATION Illumination Settings: BrightCare Max BrightCare Adjusted Illumination in an instant, always Working Distance The M525 OH4 microscope features two completely independent 300W xenon arc-lamp illumination systems, plus optional 400-watt illumination. The second system auto atically activates in the event of m lamp failure in the primary system, which gives the surgeon confidence to know that surgery will not be jeopardized due to lamp failure. BrightCare – Working-distance-controlled illumination working distance working distance auto adjustment for safer illumination levels...

SUPERIOR REACH AND HEIGHT Compact, yet provides superior reach and ample overhead room The M525 OH4 microscope features high overhead clearance and superior reach, providing the surgeon with ultimate flexibility to place the microscope wherever is most beneficial for the surgery. OH4 stand designed by Mitaka

The Leica M525 OH4 allows perfect positioning for surgery and takes up very little space in the operating room. The M525 OH4 provides superior reach, height, and clearance, which allows it to be conveniently located behind the surgeon n the unique overhead position, or positioned anywhere i around or across the operating table.

WIDE RANGE OF MOVEMENT Extraordinary movement The M525 OH4 microscope offers a wide range of movement in all dimensions for improved maneuverability. The microscope can be moved with very little force, and has minimal vibration at all magnification levels. The stand’s patented advanced movement system achieves perfect balance in six axes and at all locations and angles of the microscope. 100° range of lateral movement provides the most difficult-tomaneuver side views. 150° inclination angle range combined with the most compact microscope provides unmatched comfort, even in difficult positions....

FAST AND PRECISE BALANCE True auto-balance Leica Microsystems’ single button auto balance feature saves valuable time. The surgeon activates this feature by simply pushng the autoi balance button, which fully balances all six axes for precise positioning. Intraoperative re-balance A microscope frequently needs re-balancing during surgery due to the surgeon’s and assistant’s need to change positioning. It is easy to re-balance the microscope intraoperatively, even through a sterile drape. Simply push the AC/BC button, conveniently located above the optical head, to quickly and accurately re-balance...

MOTORIZED INCLINATION AND TILT The M525 OH4 has robotic functions on two axes (X/Y) to further enhance movement precision. The robotic functions can be activated by hand and/or foot controls. Combined with an IGS computer, the stand’s robotic ability allows the microscope to follow the surgeon’s hand instruments, thus eliminating the need for the surgeon to take his/her hand away from the surgical site to move the microscope. The handle’s ultra precise joystick allows micrometric movements for tilt and inclination. When preselected, it can also, for example, control the image injection functions....

INTEGRATED DIGITAL VIDEO Video screen integrated with floor stand The M525 OH4 microscope features a built-in, movable video screen arm, with three rotation axes and an inclination axis to best position the large video flat screen (optional) into the perfect position for all viewers. Also, all functions of the integrated video recording system are conveniently and directly controlled via the large video screen (using a keyboard, touch pad or touch screen option). Full image coverage on a 24” HD flat screen and wireless video transfer to the surgeon’s Apple® device (optional). Wireless transfer...

Ready for future imaging technologies The selection of video options continually changes as imaging technology evolves. The M525 OH4 is an open architecture system that allows the surgeon to upgrade components as new video innovations become available. The Med X Change HDMD® high-definition digital recording system is easily integrated with the Leica M525 OH4 floor stand for convenience and easy accessibility. Wide choice of Leica Video Adapters All Leica video adapters offer an intra operative fine focus to adjust the video focus. This enables the surgeon to always achieve crisp and clear focus...

OPEN ARCHITECTURE OpenArchitecture for IGS integration The DI C500 dual imaging module allows the surgeon to inject data into the eyepieces from a variety of external sources such as MRI, CT, IGS, and endoscopes. With an IGS computer the CT or MRI can be fully correlated to the image in either eyepiece. The fully correlated image can be laid over the actual image or a shutter can be used, which displays the actual image in one eyepiece and the fully correlated image in the other eyepiece. In combination with the tool tracking capabilities of an IGS system the optical axis and focal plane of the...
