RISModeling and Simulation of Flexible Needle Insertion Into Soft Tissue Using Modified Local Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Needle insertion is a widely used medical procedure in various minimally invasive surgeries. The estimation of the coupled needle deflection and tissue deformation during the needle insertion procedure is crucial to the ...
A Novel Semiemperical Friction Coefficient Model Between Needle and Polyvinyl Alcohol Tissue Phantom and Its Validation by Using Computational Inverse Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Needle–tissue interactive force is vital for developing a virtual simulation and planning system (SPS) and optimizing needle control strategy, wherein the friction coefficient is an important parameter but difficult to ...
