The stainless steel pipe is particularly used in micro-surgery and an initial cylindrical part (5) with larger section is provided with an annular gasket for clutch binding on a bearing part in the fitting seat of the sucking device (1). The duct rectilinear part (4) shows a distal elbow-shaped part (8) with inside end screw thread (9) for fitting a tip (11-13) which shows a pair of opposed bores (17-19). The said bores act as reducers of the depression and avoid the accidental sucking of fragments. By equipping the base part with tips (11-13) having suitable shapes and capacities, the pipe can comply with different requirements.
