A physical mesh-less soft tissue cutting model with the viscoelastic creep characteristics has been proposed in this paper. The model is composed of filled spheres which are connected by Kelvin structure, so as to realize the cutting with viscoelastic creep characteristics. Then, it is further compared with the mass spring model in order to verify the effectiveness of the model. Secondly, a range-based Smoothed Particle Hydrodynamics (SPH) method with variable smoothing length is proposed, in order to simulate the blood flow simulation effect in the virtual surgery training system. Finally, the two are combined to be applied to the kidney soft tissue cutting experiment in surgery trainings. Experiments show there is a significant improvement on the cutting and simulation effect in terms of the viscoelasticity of the soft tissue cutting and the pressure and viscous force of blood flow.

Practical experience shows that the autopsy assistant society is fairly divided. There are some people who would have needed a thorough basic training, and there are those who – due to their diligence and the close cooperation with physician colleagues – would deserve an opportunity for further progress due to their extensive knowlegde. As regards the autopsy assistant profession the training, and the training system as well has changed significantly, and it requires further changes. Examining the issue in a wide spectrum, the aim of the authors is, as much as possible, to promote the formation of an “Autopsy assistant career,” in which they want to create a predictable way for the members of the profession from the phase of becoming a student (competency, training, exams, vocational training, single note) to obtaining the master’s degree. The authors would like to provide a summary about their experience and plans regarding this issue. Orv. Hetil., 2015, 156(10), 399–403.
