A Review of Virtual Surgical Object Modeling Technology Based on Force Feedback

The early virtual surgical system was only developed on the computer software, and users could only interact with the surgical model through the mouse. The disadvantage of this way was that users could not get tactile feelings. Therefore, with the development and progress of virtual reality technology, force feedback equipment has been introduced into virtual surgery, and has become a research hotspot in this field, in order to make efforts to feedback equipment in the research institute and higher and higher utilization rate. Researchers, teachers and students used force feedback devices to improve the immersion of virtual surgical system. This article mainly introduced the virtual modeling method in the operation, including geometric modeling and physical modeling, the geometric modeling of the two models are introduced, and summarizes their advantages and disadvantages, the physical modeling of soft tissue deformation modeling of three models are analyzed and compared, and the feedback force calculation model are introduced, finally, expounds some problems faced by modeling technology, virtual surgery The future development is also prospected.
