In an actual operation, errhysis in the wound happens frequently during surgery cutting. Most previous studies, focus on skin or organ surface more than dynamic blood oozing in the inner wound. Therefore, upon the requirements of authenticity and real-timing, an oozing simulation model combined with force feedback was proposed. The model used Lagrangian approaches in fluid simulation system, and especially simplified the traditional Lagrangian approaches in this specific liver cutting process. The experimental results show that it can meet the demand of authenticity and real-time in dynamic ooze blood simulation.
