Abstract

Comparative analysis of the mode of deformation of hollow organs (extrahepatic bile ducts at the site of stricture) was carried out by the finite elements method during interventions in the lumen using stone extraction Dormia basket made of stainless steel and NiTi. Geometrical and physical models of the ducts and basket were created, strain and deformation fields in the choledochal walls were determined, criteria of traumaticity and medical technological requirements to the material and geometry of lithoextractors were formulated.
