The invention requests to protect an identification coding method for a medical instrument, and the method comprises the following steps: U1, carrying out the identification coding of a raw material needed by the production of medical instrument equipment, and uploading the raw material to an enterprise database; U2, identifying production information such as machinery, operators and production processes of the production line; U3, for materials, production processes, products and the like which have been coded and identified, identifying identification codes through carriers such as two-dimensional codes, bar codes, RFID and the like, and carrying out full-life-cycle data recording on raw materials, the production processes and the products through related identification technologies; andU4, according to the code identifier of the product, performing identifier analysis on the code identifier to obtain full life cycle information of the product, thereby facilitating product traceability, quality control and product supervision. According to the invention, the full life cycle of the medical instrument industry from materials, finished products, after-sales service and the like isidentified, so that the effects of product traceability, quality control and production supervision are realized.
