Stability Analysis of the Key Parts of the Continuous Body of Laryngeal Surgery

For the fibrillation that exists in the larynx operation, in this paper, the stability of the key parts in continuum mechanism is analyzed, based on the software of Ansys, the static model of interval disk, four joint bending section and six joint bending section is established, and the statics analysis is carried out, and the displacement cloud image in X direction and the displacement cloud in Y direction are obtained. The Z-direction of the displacement cloud, the total displacement cloud and the "von Mises" equivalent stress distribution diagram, the results show that each member in the X,Y and Z direction of the displacement is relatively small, within the scope of the operation allowed, can be used as a continuum of body parts, The theoretical basis of statics is provided for the whole machine analysis of continuum mechanism. Based on Ansys Workbench Software, the dynamic finite element model of the universal driving bending mechanism is established, and the free modal and constrained modal analysis of the universal drive bending mechanism is carried out. In order to study the overall dynamic characteristics of the institution after applying the constraint, according to the analysis of the first 10-order modal modes, it is known that there are more local modes in the mode of free mode mode, and more overall modes in the modal modes of constraint mode, which shows that the dynamic characteristics of the machine are better after the constraint is imposed on the mechanism. Based on Ansys and Ansys Workbench Software, the dynamic finite element model of disk and end actuator is established, based on the analysis of the constrained modal, the calculation results of the first ten-order modal natural frequencies and the corresponding modes are obtained, and the range of natural frequencies of each structure is determined, which provides the theoretical basis for the whole machine analysis of continuum mechanism. It also provides a theoretical basis for the removal of fibrillation in surgery.
