Embodiment 1
[0033] figure 1 A schematic structural view of a specific embodiment of the balloon dilatation catheter provided in this application.
[0034] Such asfigure 1 and figure 2 As shown, the balloon dilatation catheter includes: an outer tube 1 , an inner tube 2 , a balloon 3 , a connector 4 , a developing mark 5 , and a stress diffusion tube 6 .
[0035] The outer tube 1 is a hollow structure, the proximal end of the outer tube 1 is fixed with the connecting piece 4 and is sealed with the connecting piece 4 , and the distal end of the outer tube 1 is sealed and fixed with one end of the balloon 3 . In addition, in order to ensure that the distal end of the outer tube 1 is soft enough to enter blood vessels, and that the proximal end of the outer tube 1 is hard enough to provide a greater thrust when pushing, in other embodiments of the present application, the outer tube 1 can also be A multi-stage design is adopted, that is, from the far end to the proximal end of the outer tu...
