Abstract:
Laparoscopic procedures have various benefits for the patients but come with environmental limitations for
the surgeons. Therefore to prevent serious complications, surgeons require intensive and repetitive training
to acquire essential techniques, skills or tasks. There are various training systems used in surgical programs;
a recent technology that shows promise is virtual reality (VR) training. An important aspect of these training
systems is the realism of the soft tissue model and the user interface, which allow effective transference of
skills from the training system to the operating room. This paper discusses a novel method to model soft
tissue in virtual reality training systems and the validation of this model. Wave equation, a mathematical
model, is used to model the soft tissue and laparoscopic tools’ interaction. This model is validated using
finite element analysis, which is used to compare the mechanical properties of the resulting material and
human skin. The model di
scussed in this paper will be applied to a novel surgical training system, which
trains the user in laparoscopic suturing techniques.
