In order to improve the effectiveness of percutaneous diagnosis and therapies,the needle insertion into the deforming soft and inhomogenous tissue should be accurate. In this study a needle with 6 degrees of freedom force / torque sensor is used to find the relationship between the pathway's length and the force. Our experiments show that the method with repeated extraction-insertion cycles can make the needle approach the target as much as possible. M eanwhile ! a method to obtain the appropriaterepeated extraction-insertion cycles is given to drive the needle to execute the repeated cycles efficiently. Experiments and discussions were conducted to preliminarily validate the method.
