Modeling of Looping Behavior in a Flexible Instrument Using a Bézier Curve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible medical instruments undergo looping during insertion and navigation inside the human body. It makes the control of the distal end difficult and raises safety concerns. This paper proposes the minimum strain energy ...
Deformation Modeling of a Flexible Instrument Using a Bézier Curve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible instruments are extensively used in medical applications. Manipulation of these instruments is challenging and troublesome. To study the behavior of these instruments, different modeling approaches like finite ...
Modeling of a Flexible Instrument to Study its Sliding Behavior Inside a Curved Endoscope
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Improved Force Transmission of a Flexible Surgical Instrument by Combining Input Motion
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Flexible Multibody Modeling of a Surgical Instrument Inside an Endoscope
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Design of an Experimental Set Up to Study the Behavior of a Flexible Surgical Instrument Inside an Endoscope
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
