The invention relates to the technical field of medical auxiliary instruments, in particular to a
ureter distortion auxiliary supporting guide wire which comprises an extension guide wire, a position guide wire, a guide wire head and a connecting sleeve seat. The position guide wire is provided with an expansion base ring and at least three sets of plate type expansion assemblies driven by a pneumatic mechanism I. The plate type expansion assemblies drive arc-shaped expansion plates to swing through tooth bars, point type and controllable expansion of the narrow portion of the
ureter is achieved, and the problems of
mucous membrane damage and complete lumen blockage caused by large-area contact of a traditional air bag are solved. And meanwhile, an
air cavity and at least three groups of radial movement positioning assemblies driven by a pneumatic mechanism II are arranged in the guide wire head, and an arc-shaped positioning plate is pushed by a multi-stage
telescopic cylinder to extend out in the radial direction to form multi-
point contact with the inner wall of the
renal pelvis, so that stable anchoring of the guide wire head is realized. The operation
injury risk can be effectively reduced, smooth
perfusion is guaranteed, and the positioning stability of the guide wire in the
renal pelvis is improved.
