Fully digital 3D surgical microscope „ARRISCOPE“

Surgical microscopes are usually used for surgical therapy in ear, nose and throat medicine. These allow the surgeon to view the situs at an adequate magnification and illumination, and to carry out surgical therapies. The spectrum ranges from the removal of pathological structures, the replacement of the partial or total ossicular chain by implants, up to hearing implants that are inserted directly into the cochlea.

Advantages of digitization in surgical microscopy

The ARRISCOPE captures the respective image section with a high-resolution and highly sensitive camera sensor from the cinema technology and displays the image in a digital binocular. In addition, the identical perspective of the surgeon can be reproduced in two or three dimensions on any number of displays.

Additional information, such as patient-specific preoperative imaging or vital parameters, can be fed directly into the binocular and thus optimize the clinical workflow.

Another advantage of digital image capture is the possibility of generating additional information from the image data: by means of optical calibration and efficient image processing algorithms, for example, a depth map can be generated that allows three-dimensional measurement in the sub-millimeter range. This function, which is currently undergoing clinical evaluation, enables the surgeon to select the prosthesis that best suits the patient.

The connected image processing chain simultaneously optimizes tissue differentiation: by means of so-called "looks", a real-time recognition and adjustment of individual color channels, which works in combination with illumination in specially adapted wavelength ranges, structures can be highlighted and thus simplify the surgical procedure.

ARRI is supplying the hardware for this project, Fraunhofer HHI is providing the algorithms for the image analysis.
