    Introduction: The evolution of liposuction and fat graft technique with the oncologic safety allowed to use the fat as autologous filler in patients with breast cancer and submitted to breast reconstruction. Objective: Introduce an innovation in the instrument used to harvest fat graft to use in patients with breast cancer and sent to Instituto Nacional de Propriedade Industrial as utility model patent. Method: Search of anteriority and trademarks were performed at internationals and nationals databases, and a prototype was built as a fat harvest instrument with 35 cm length, 4 cm of diameter, 10 holes at the distal extremity, with 2mm diameter each. It was performed an experiment with harvest of a viscous substance, comparing the prototype with 2 regular industry cannulas type: 3 holes Mercedes’s type and 5 roles Pitangy’s type. Results: Four patents of high relevance, and 1 patent of media relevance were founded, and were different from the prototype propose in the distal extremity design or harvest function. When the efficiency of the prototype was compared with the other cannulas, the cannula with 5 holes Pitangy’s type was the most efficient, and it was not founded statistic difference between the prototype and the cannula with 3 roles Mercedes’s type. Conclusion: A prototype with 10 holes at the distal extremity with 2 mm each was built, developed for an efficient harvest of fat blocks until 2mm of diameter, to use in breast reconstruction.
