    Introduction: The Skin Is The External Coating Organ Of The Human Body And Is Subject To Lesions. Partial Skin Graft Is The Current Golden Standard To The Treatment Of Traumatic Loss Of Skin, Especially When Involving Burns. To Remove The Skin Graft Devices In Knife Shapes And Later Dermatomes Were Created. Devices To Remove Skin That Used A Razor Blade Were Developed. However, There Is No Such Device To Remove Small Skin Grafts And/Or To Do Surgical Debridment Which Are Pratical And Have Low Cost. Objective: To Develop A Device To Remove Skin And/Or Do Surgical Debridment. Methods: A Knife Shape Device Was Idealized. Its Blade Has A Cutting Double Face. The Device Was Classified By Means Of The International Patent Classification. A Bibliographic Search Was Done Using The Health Sciences Descriptors (Decs): Skin, Skin Graft, Transplant And Surgical Instruments, In Addition To The Key Words: Razor, Knifes And Dermatomes. The Search For Anteriority Was Done Using Patent Banks. Then, Prototypes Were Constructed

    PURPOSE: To implement a plan of preventive maintenance developed for users of the phacoemulsification machine. METHODS: In order to implement a maintenance program for a phacoemulsification machine, Alcon's Legacy 20000 was chosen. Its operating manual was used as a primary search, so that the probability of equipment malfunction or breakdown could be quantified. The maintenance condition of Legacy 20000 was checked in some hospitals in São Paulo through an interview with the responsible clinical engineers. Surgeons working at the Cataract Sector of UNIFESP (Universidade Federal de São Paulo (UNIFESP)) were asked their opinion about the functioning of Legacy 20000 , in order to indentify the main sources of malfunction. After research had been carried out in hospitals and with the surgeons, a maintenance manual for the Legacy 20000 was proposed, based on preventive maintenance tools. RESULTS: The analysis regarding error messages showed that most potential problems and corrective measures to be taken are due to problems of connection or fixation of the cables. The Legacy 20000 main sources of malfunction were identified in the São Paulo Hospital, which had acquired its own piece of equipment. In most cases they were related to broken ultra-sound handpiece, broken electronic and mechanical components, faulty setup and problems of priming, vacuum and aspiration. The interview with the cataract surgeons of the Universidade Federal de São Paulo (UNIFESP) showed lack of technical knowledge due to their lack of familiarity with the manual and no training regarding equipment functions. CONCLUSIONS: There is no complete plan of preventive maintenance for the Legacy 20000 in the hospitals considered for this research only corrective maintenance. The manual of preventive maintenance item proposed for Legacy 20000 was prepared based on the research results using preventive maintenance tools.
