Medical catheter with controllable and visible head-end bending angle

Abstract

The application discloses a medical catheter with controllable and visible head end bending angle, and belongs to the technical field of vascular interventional treatment. The medical catheter with controllable and visible head end bending angle comprises, from far to near, a soft head, a distal end control section, a catheter body and an operation and visual assembly carried on the catheter body, a bending control is symmetrically arranged in a cavity of the distal end control section, the bending control comprises a scissor type structure unit, a hinge point and a connecting component, adjacent scissor type structure units arranged in an axial direction are connected through the hinge point, and the connecting component is connected with the hinge point. The bending angle of the catheter head end is adjusted through the operation and visual assembly, and the specific value of the bending angle can be observed on a display screen, so that the success rate and safety of interventional treatment are improved, the target part can be effectively reached through accurate positioning and control, and damage to surrounding tissues is reduced.
