Modelling Surgical Cuts, Retractions, and Resections via Extended Finite Element Method
نویسندگان
چکیده
We introduce a new, efficient approach for modelling the deformation of organs following surgical cuts, retractions, and resections. It uses the extended finite element method (XFEM), recently developed in ”fracture mechanics” for dealing with cracks in mechanical parts. XFEM eliminates the computationally-expensive remeshing that would be required if the standard finite element method (FEM) was used. We report on the successful application of the method to the simulation of 2D retraction. The method may have significant impact on surgical simulators and navigators.

On Extended Finite Element Method (XFEM) for Modelling of Organ Deformations Associated with Surgical Cuts
The Extended Finite Element Method (XFEM) is a technique used in fracture mechanics to predict how objects deform as cracks form and propagate through them. Here, we propose the use of XFEM to model the deformations resulting from cutting through organ tissues. We show that XFEM has the potential for being the technique of choice for modelling tissue retraction and resection during surgery. Can...
متن کاملSimulating energy method for grout-induced crack analysis of rock structures at Chadormalu mine by extended finite element method
Fracture mechanics is a vital component involved in studying the exact behavior of rock materials. Detection and assessment of the behavior of rock joints injected by grout plays an important role in numerical modelling in rock mechanic projects. The importance of mechanisms associated with initiation and propagation of cracks due to hydraulic fracturing has led to a considerable interest in in...
متن کاملSimulation of Surgical Cutting Using a Progressive Cutting Scheme and Extended Finite Element Method
Accuracy and speed are two of the most important problems in the real-time Finite Element Method (FEM)-based simulations of surgical cutting [1][2]. While the latter can be gradually eased through GPU-based acceleration[3][4], the former hasn't been properly addressed even until recently. To enable realistic and accurate simulation, the cutting line should follow the exact movement of the user-...
متن کاملTissue Resection using Delayed Updates in a Tetrahedral Mesh
In open surgery simulations, cuts like incisions and resections introduce irreversible changes to underlying geometry. In such circumstances, updating tetrahedral meshes for sophisticated physical modeling methods like finite elements becomes computationally intensive. We present an algorithm that does not need to update every time there is an incision. It allows multiple incisions and only per...
متن کاملExtended Finite Element Method for Statics and Vibration Analyses on Cracked Bars and Beams
In this paper, the extended finite element method (XFEM) is employed to investigate the statics and vibration problems of cracked isotropic bars and beams. Three kinds of elements namely the standard, the blended and the enriched elements are utilized to discretize the structure and model cracks. Two techniques referred as the increase of the number of Gauss integration points and the rectangle...
