Summary: | A traction bending control technology is applied to the perfusion balloon dilatation catheter for the first time, a traction cavity is formed in a main tube, a bending control mechanism is arranged in a tube seat, and a traction wire arranged in the traction cavity and used for connecting the far end of the main tube and the bending control mechanism is arranged, so that a functional structure for controlling bending of the catheter is formed; the perfusion balloon dilatation catheter is matched with a special structure that a plurality of single balloons circumferentially surround and support a dilated blood vessel and a blood flow channel is reserved between the single balloons and the end tube, the perfusion balloon dilatation catheter is endowed with a controllable bending function when being conveyed in a lumen, so that the perfusion balloon dilatation catheter can be controlled to be bent along with the shape of the lumen during an operation, and the perfusion balloon dilatation catheter can be smoothly |
