Simulated Interactive Needle Insertion
نویسندگان
چکیده
A novel interactive virtual needle insertion simulation is presented. Simulation models are based upon planar tissue deformations and forces measured during needle insertion experiments. Users are able to control a three-degree-of-freedom virtual needle as it penetrates a linear elastostatic tissue model, while experiencing steering torques and lateral needle forces through a planar haptic interface. Efficient numerical computation techniques permit fast simulation of relatively complex two-dimensional and three-dimensional environments at haptic control rates.

Needle insertion and radioactive seed implantation in human tissues: simulation and sensitivity analysis
− To facilitate training and planning for medical procedures such as prostate brachytherapy, we are developing an interactive simulation of needle insertion and radioactive seed implantation in soft tissues. We describe a new 2D dynamic FEM model based on a reduced set of scalar parameters such as needle friction, sharpness, and velocity, where the mesh is updated to maintain element boundaries...
متن کاملSensorless Motion Planning for Medical Needle Insertion in Deformable Tissue
Minimally invasive medical procedures such as biopsies, anesthesia drug injections, and brachytherapy cancer treatments require inserting a needle to a specific target inside soft tissue. This is difficult because needle insertion displaces and deforms the surrounding soft tissue causing the target to move during the procedure. To facilitate physician training and pre-operative planning for the...
متن کاملSimulations of Needle Insertion by Using a Eulerian Hydrocode FEM and the Experimental Validations
In this paper, simulations for needle insertion were performed by using a novel Eulerian hydrocode FEM, which was adaptive for large deformation and tissue fracture. We also performed experiments for the same needle insertion with silicon rubbers and needles, which had conical tips of different angles in order to investigate the accuracy of the simulations. The resistance forces in the simulati...

متن کاملModelling, Simulation and Planning of Needle Motion in Soft Tissues
Precise needle placement is required for the success of a wide variety of percutaneous interventions in medicine. Insertions into soft tissues can be difficult to learn and to perform, due to tissue deformation, needle deflection and limited visual feedback. Little quantitative information is known about the interaction between needles and soft tissues during puncture, and no effective physical...
