Abstract:

BACKGROUND: Friction that appears during soft tissue puncturing process is a very complex non-linear phenomenon, and it is an important part of interaction force between the needle and soft tissue. Therefore, it affects the efficacy and accuracy of puncture biopsy. However, studies on the effect of ultrasonic vibration on friction during the needle insertion process are few.
OBJECTIVE: To clarify the effect of ultrasonic vibration amplitude on the friction force during soft tissue puncturing and verify the correctness of the friction model, thereby providing the theoretical basis for the development of ultrasonic vibration-assisted sampling device and improving efficiency of puncture biopsy.
METHODS: A new ultrasonic vibration-added model was introduced based on the LuGre model, and the reason for a decrease in the friction force after added the ultrasonic vibration was analyzed through the friction model. The varying pattern of friction with the amplitude increasing was obtained and the correctness of theoretical model was certified.
RESULTS AND CONCLUSION: The friction during the needle insertion process significantly reduced after added with ultrasonic vibration. The frictional force decreasing relation with the increasing of amplitude was power function. These results reveal that the friction model based on the LuGre model can correctly reflect the influence of the amplitude on the friction during ultrasonic vibration-assisted needle insertion into soft tissues.
