Needle Deflection during Insertion into Soft Tissue Based on Virtual Spring Model
Needle insertion is the most common procedure of minimally invasive interventions. During insertion into a soft tissue, the needle with bevel tip can deflect due to the asymmetric forces acting on the tip of the needle. In this paper, a mechanics-based model is developed to predict the needle deflection. In the model, the needle is considered as a cantilever beam supported by a series of nonlin...
متن کاملA New Hybrid Viscoelastic Soft Tissue Model based on Meshless Method for Haptic Surgical Simulation
This paper proposes a hybrid soft tissue model that consists of a multilayer structure and many spheres for surgical simulation system based on meshless. To improve accuracy of the model, tension is added to the three-parameter viscoelastic structure that connects the two spheres. By using haptic device, the three-parameter viscoelastic model (TPM) produces accurate deformationand also has bett...
متن کاملSoft Tissue Modeling Using ANFIS for Training Diagnosis of Breast Cancer in Haptic Simulator
Soft tissue modeling for the creation of a haptic simulator for training medical skills has been the focus of many attempts up to now. In soft tissue modeling the most important parameter considered is its being real-time, as well as its accuracy and sensitivity. In this paper, ANFIS approach is used to present a nonlinear model for soft tissue. The required data for training the neuro-fuzzy mo...

متن کاملNeedle Insertion Modelling and Simulation
A methodology for estimating the force distribution that occurs along a needle shaft during insertion is described. An experimental system for measuring planar tissue phantom deformation during needle insertions has been developed and is presented. A two dimensional linear elastostatic material model, discretised using the Finite Element Method, is used to derive contact force information that ...
