INTRODUCTION: Several studies have demonstrated the clinical benefits of the use of high resolution instruments in surgery, with reduction in the operative time, easy handling and effectiveness in the incisions, as well as lower smoke generation and thermal tissue damage. AIM: To demonstrate the technical feasibility of reusing devices of high resolution for cutting and coagulation, theoretically recommended for single use. METHOD: Was evaluated the efficacy of cleaning, sterilization process and functional quality of the material. The process was applied in four tweezers brand Ligasure - Valleylab. Each was identified with ribbons of different colors autoclavable for tracking. Two were submitted directly to the cleaning after the first use and from the other two were collected samples of this cleaning for the first culture. All tweezers passed through the cleaning process prior to sterilization. Then were sterilized in hydrogen peroxide. After the sterilization process, was taken material from the devices and put it on saline solution for culture. After, the tweezers were tested by a surgeon to analyze its performance in a sample of beef. Randomly at each test the researcher contaminated tweezers with strains of Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. This process was repeated four times. The material was sent to the laboratory and seeded in culture medium capable of microbiological identification. For quality control tests all biological, chemical and quality certification of products used in the process were attached. RESULTS: The results of all cultures were negative, and functionality was preserved in the four reuses. CONCLUSION: As to the functionality, the tweezers may be used at least four times, the number of times tested in this experiment. Therefore, it can be used for five times, the first coming from the factory and four more after reprocessing.
