A Real Time Simulator for Virtual Surgery

چکیده
In the paper the basics and the software concept of a real time simulator for virtual surgery is presented. The simulator is aimed to be applicable in soft tissue surgery and has been tested in virtual laparoscopy. The general software concept is presented first. Then the modeling approach of soft tissues, such as liver, gall, milt etc., is decribed. The main challenge is to achieve a good physical approximation of the nonlinear dynamic behavior of soft tissues which still allows a real time performance of the simulator. Due to the quality requirements a finite element approach is used, which includes the contact conditions between the organs and the organs with surgical instruments as well. Some simplifications to increase the computational speed are discussed.

The context of this research is the development of a pedagogical surgery simulator for colon cancer removal. More precisely, we would like to simulate the gesture which consists of moving the small intestine folds away from the cancerous tissues of the colon. This paper presents a method for animating the small intestine and the mesentery (the tissue that connects it to the main vessels) in rea...

BACKGROUND With the decrease in the number of cerebral aneurysms treated surgically and the increase of complexity of those treated surgically, there is a need for simulation-based tools to teach future neurosurgeons the operative techniques of aneurysm clipping. OBJECTIVE To develop and evaluate the usefulness of a new haptic-based virtual reality simulator in the training of neurosurgical r...
متن کاملMesh Cutting Algorithm for Use in an Orthopaedic Surgery Simulator
In order to develop a podiatric orthopaedic training simulator the obstacle of simulating podiatric bone surgery must be overcome. In order to simulate this surgery appropriately, it is necessary to be able to cut through a virtual representation of a patient’s foot on-screen in real-time. We investigate several methods of cutting through simulated objects in general, and evaluate their usefuln...

Today’s real-time operation environments almost exclusively limit themselves to smallscale local deformations, linear strain measures and soft material. Real-time and numerically stable simulation of non-linear as well as stiff volumetric bodies is computationally very challenging and has not yet been integrated into such environments. Virtual surgery simulators, on the other hand, need to inco...
