description | The invention relates to a process for coating the useful surfaces of a surgical instrument intended for intrasurgical assessment of surgical margins of tumours and determining the type thereof. According to the invention, the process consists in preparing, in an essential oil for medical use, a solution of metallic nanopowders of Au having the size of 10...30 nm and Ag, respectively, having a purity of 99.9%, in a concentration of 20...50%, at the ambient temperature, after which it is deposited in an amount of 0.01...0.05 ml onto the useful steel surfaces of the instrument, by centrifugation, at a rotary speed of 500...1000 rpm, the resulting film being dried for 120...180 min at the ambient temperature, heat treated in a vacuum oven of 10Torr, at 150...190°C, for 70...100 min, with natural cooling down to the ambient temperature, resulting in a nano structured coating of Au and Ag of uniform roughness, which adheres to the useful surfaces, is resistant to the usual sterilization temperature, oxidation- and exfoliation-proof.
Invenţia se referă la un procedeu de acoperire a suprafeţelor utile ale unui instrument chirurgical utilizat pentru evaluarea intraoperatorie a marginilor chirurgicale a tumorilor, şi depistarea tipului acestora. Procedeul conform invenţiei constă în prepararea la temperatura camerei, într-un ulei esenţial de uz medical, a unei soluţii de nanopulberi metalice de Au de dimensiuni 10...30 nm, respectiv, Ag, de puritate de 99,9%, în concentraţie de 20...50%, după care aceasta se depune în cantitate de 0,01...0,05 ml pe suprafeţele utile din oţel ale instrumentului, prin centrifugare, cu o viteză de rotaţie de 500...1000 rpm, filmul rezultat se usucă timp de 120...180 min la temperatura camerei, se tratează termic într-o etuvă cu vid de 10Torr la 150...190°C, timp de 70...100 min, cu răcire naturală până la temperatura camerei, rezultând o acoperire nanostructurată de Au şi Ag, aderentă la suprafeţele utile, rezistenţă la temperatura uzuală de sterilizare, care nu oxidează şi exfoliază, cu rugozitate uniformă. |
