N2 - The aim of the work was to assess the operational damage of surgical instruments. As part of the research, the surface, structure, mechanical properties and corrosion resistance of the bone gouge forceps and haemorrhoidal forceps withdrawn from use after the intended period of operation were assessed. The test results showed numerous scratches, dents, cracks and chipping caused by operation and storage on the entire surface of the tested tools, which had a direct impact on the increase of the surface roughness. For the bone gouge forceps, non-metallic inclusions were classified as type D: thin globular oxides with an approximate thickness of up to 8 μ m and the pattern number of 1.5, and for haemorrhoidal forceps as type D: thick globular oxides with a thickness of 12 μ m and the pattern number of 1.5. Microscopic metallographic examinations showed in the working part of the analyzed tools (both the bone gouge forceps and haemorrhoidal forceps) the structure of low-tempered martensite with visible retained austenite, whereas in the gripping part, the martensite structure in the annealed state. The obtained results of the hardness test showed that in the case of the working part of the bone gouge forceps, the gripping and the working part of the hemorrhoid forceps, the values met the recommendations given in the standards. The test of droplet corrosion resistance showed that all surgical instruments selected for the test are corrosion resistant.
