Abstract :
A novel force model for needle insertion into soft tissues has been developed for virtual reality and haptics based simulation of percutaneous therapies. The forces are divided into two parts, stiffness force and friction force, for which a blood vessel model is used in order to improve the realism. The validity of the developed model is confirmed by a comparison between the results from the developed model and those derived from real data.
