Process traceability of surgical instruments (DMi, i being a positive integer) in a hospital, the corresponding process implemented by computer incorporating: - an acquisition phase (P1) which includes: placing (S1) of a surgical instrument ( DMi) in a support (10) platform capturing (S4), with the help of a digital camera (20) above the support (10) platform, at least one digital image (I) comprising at least a portion of the surgical instrument (DMI) image processing (S5) for detecting, in the corresponding at least one digital image (I), at least one visual feature of the corresponding surgical instrument (DMI) and to determine at least one visual data (P_PICi) associated the corresponding visual characteristic measurement (S6) weight of the surgical instrument (DMI), with the help of a digital scale (40), to obtain weight data (D_PDSi) containing information relating to the measured weight - a stage of processing (P2) which includes an identification (S9) of the corresponding surgical instrument (DMI), especially consisting of: comparing (S9_1) the weight data (D_PDSi) and visual data (D_PICi) with a database (DB) that establishes a relationship between at least one surgical instrument (DMI) and the information relating to weight and visual characteristic of the corresponding at least one surgical instrument, and determining (S9_2), according to the corresponding comparison, at least one identification data (DIi) containing information relating to the identity of the corresponding surgical instrument (DMI), characterized in that the database (DB) integrates, for each surgical instrument (DMI), a data location (DLi ) containing information relating to a site (Pi) corresponding default surgical instrument (DMi) in a surgical kit (KT), and therefore integrates a recomposition phase (P3) corresponding kit (KT) comprising: - a step of locating (10) during the site (Pi) of the corresponding surgical instrument (DMi) in the corresponding surgical kit (KT) according to
