2A1-S11 Distinction of Singularity in Operation Using Self-organizing Map and Construction of Warning System of Singularity in Operation for Endoscopic Surgery(Medical Robotics and Mechatronics(2))

Abstract

In this paper, a method for automatic identification of a surgical operation in endoscopic surgery and distinction of the singularity of the identified surgical operation is proposed. Surgical operation of ligation is divided into seven operations, and on the basis of the threshold criteria, a surgical operation is identified as one of them. Next, when the surgical operation is identified as a thread knotting, the operation of thread knotting is classified as either normal or singular using a self-organizing map. In addition, construction of a warning system to avoid medical errors by presenting detection of the singular operation to surgeon and to provide safe endoscopic surgery was executed.
