Embodiment 1
[0065] The present invention provides a cutting-type balloon expansion device, such as Figure 1 to Figure 10 As shown, it includes a handle shell 1 , a positioning bracket 61 , an inner tube 3 , an outer sheath 2 and a catheter 4 .
[0066] Wherein, the catheter 4 is sleeved outside the inner tube 3, and the outer sheath tube 2 is sleeved outside the catheter 4; the balloon 5 is sleeved outside the inner tube 3, and the proximal end of the balloon 5 is fixed on the distal end of the catheter 4; The distal end is sealed on the inner tube 3 , and the inner cavity of the balloon 5 communicates with the first passage between the catheter 4 and the inner tube 3 ; the distal end of the inner tube 3 is fixed with a tapered head. The outer sheath tube 2 , the inner tube 3 and the catheter 4 are all pierced on the handle shell 1 .
[0067] There are at least two positioning brackets 61, one end of any positioning bracket 61 is fixed on the catheter 4 or the balloon 5, and the other e...
Embodiment 2
[0112] This embodiment provides a cutting-type balloon dilation device. Compared with the dilation balloon 5 catheter 4 device provided in Embodiment 1, the only difference is:
[0113] The structure of positioning bracket 61 is different, as Figure 13 As shown, the positioning bracket 61 is in the form of a bar block or a bar column; in the non-working state, the positioning bracket 61 is distributed on the same straight line along the axial direction of the balloon 5; the proximal end of the positioning bracket 61 is fixed on the proximal end of the balloon 5 Above, the distal end of the positioning bracket 61 is suspended outside the balloon 5 , and in the working state, the positioning bracket 61 expands and deforms along the shape of the balloon 5 in the first direction.
[0114] or, as in Figure 12 As shown, the positioning bracket 61 includes a mounting portion 612 and a limiting portion 613. The distal end of the mounting portion 612 is fixed on the distal end of th...
