Resumo do Trabalho:

Real-time physically plausible simulations have been increasingly employed in medical simulations in the last twenty years, more specifically at representing the surgery environment in order to provide a medium for surgeons studying, practicing and planning surgeries. Such simulations pose uncounted challenges due to its complexity when approximating physical behaviors of different tissues and surgical apparatus interactions, and that way promote a whole new field of research towards developing techniques and technologies to build a proper real-time solution. As inseverable components to a surgery, as well as in a surgeon training, is suturing and knot tying. These steps are just as ubiquitous as incisions in a procedure and play an important role as, for instance, in improving the patient’s recovery, and also the overall success of an operation. For such purpose, it is of prime importance to know and to account a simulation’s state for control and feedback, whether intended for the user or for supporting the simulation itself. This translates into the problem of identifying which and how well knots are being tied in a suturing simulation task. This work proposes knot identification and assessment for an interactive knot tying simulation. The evaluation happens through reckoning the topological aspect of thread’s current disposition using both Gauss notation matching and Alexander’s polynomials, as well as other metrics from the thread.
