Abstract: We present the exact constraint design of a two degrees of freedom crossflexurebased stage that combines a large workspace to footprint ratio with high vibration mode frequencies. To maximize unwanted vibration mode ...

Abstract: Flexible instruments are increasingly used to carry out surgical procedures. The instrument tip is remotely controlled by the surgeon. The flexibility of the instrument and the friction inside the curved endoscope jeopardize ...

Abstract: The force transmission of a flexible instrument through an endoscope is considerably deteriorated due to friction between the contacting surfaces. Friction force along the axial direction can be reduced by combining the ...

Abstract: In this study, a modeling approach is developed to examine laminar flow effects on the rotordynamic behavior of highspeed mini rotating machinery with a moderate flow confinement. The existing research work mostly focuses ...

Abstract: The implementation of flexible instruments in surgery necessitates high motion and force fidelity and good controllability of the tip. However, the positional accuracy and the force transmission of these instruments are ...

Abstract: The success of flexible instruments in surgery requires high motion and force fidelity and controllability of the tip. However, the friction and the limited stiffness of such instruments limit the motion and force transmission ...
