摘要

Surgical instrument for cutting, removal or suction of material from an operation area (1), has a head part (7) for said cutting, removal or suction and a light source (5) for generation of illuminating light. Back-scattered and reflected light is detected by a detector (6). The detector is not an imaging detector, rather it is used to detect the light intensity and generate a signal that can be used to classify the tissue based on its specific properties.
