[0033] A mounting base 2, on which a cylinder 3 is arranged;

[0034] A through hole is formed in the piston rod 31 of the cylinder 3, and an inner retaining ring is formed at the front end of the through hole;

[0035] The inflatable rod 4, whose front end passes through the mounting seat 2 and is inserted from the rear end of the through hole, the inflatable rod 4 rotates in the mounting seat 2 and the piston rod 31, and the inflatable rod 4 is axially abutted against the mounting seat 2 to limit the inflatable rod 4 from moving backwards, and an inflatable hole is formed in the inflatable rod 4, the rear end of the inflatable hole is suitable for connecting to an air source, and a silicone sealing ring 6 is provided at the front end of the inflatable hole;

[0036] A pressing block 5 is arranged in the through hole and is located between the inner retaining ring and the inflation rod 4. A pipe penetration hole is provided in the pressing block 5. The rear end of the pressing block 5 is axially abutted against the silicone sealing ring 6 so that the pipe penetration hole, the inner hole of the silicone sealing ring 6 and the inflation hole are connected. A spring 7 is arranged between the pressing block 5 and the inflation rod 4. The spring 7 presses the pressing block 5 against the inner retaining ring.

[0037] The rear end of the balloon catheter passes through the pressing block 5 and extends into the silicone sealing ring 6. The piston rod 31 moves backward, driving the pressing block 5 to squeeze the silicone sealing ring 6 backward, so that the silicone sealing ring 6 radially clamps and seals the internal balloon catheter. The pressing block 5 and the inflation rod 4 drive the balloon catheter to rotate synchronously.

[0038] Specifically, as an optional implementation in this embodiment, Figures 2 to 4 As shown, a first ferrule 41 is arranged between the inflatable rod 4 and the mounting seat 2, a rod hole is provided in the mounting seat 2, an inner step is formed in the rod hole, a rear outer step is formed on the inflatable rod 4, and the first ferrule 41 is sleeved on the inflatable rod 4 and axially abuts between the inner step and the rear outer step;

[0039] A second ring 42 is arranged between the inflation rod 4 and the through hole. A front outer step is formed on the inflation rod 4. The second ring 42 is sleeved on the inflation rod 4. The rear end of the second ring 42 abuts against the front outer step, and the front end of the second ring 42 abuts against the spring 7.

[0040] In this embodiment, the first ring 41 and the second ring 42 provide radial support for the inflatable rod 4 and also limit the position in the axial direction. The inflatable rod 4 rotates in the two rings.

[0041] Specifically, as an optional implementation in this embodiment, a pulley 11 is provided on the inflation rod 4, and the pulley 11 is connected to the motor 1 via a belt.

[0042] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, the pressing block 5 includes a column 51 and a ring 52. A tube-through hole is provided in the column 51.

[0044] The working principle of the balloon catheter inflation clamping and rotating device is as follows: the piston rod 31 of the cylinder 3 moves forward and backward, thereby driving the internal pressure block 5 to move forward and backward. When the piston rod 31 drives the pressure block 5 to move backward, the rear end of the column 51 of the pressure block 5 squeezes the silicone sealing ring 6, thereby causing the silicone sealing ring 6 to deform radially, thereby clamping the internal balloon catheter diameter. After clamping, the gas input from the rear end of the inflation rod 4 can be delivered to the balloon catheter. In addition, the motor 1 drives the inflation rod 4 to rotate, thereby driving the balloon catheter and the pressure block 5 to rotate together, realizing the clamping, inflation and rotation of the balloon catheter. As the piston rod 31 resets forward, the spring 7 abuts against the pressure block 5 and moves forward together, and the pressure block 5 releases the pressure on the silicone sealing ring 6, and the balloon catheter is released and removed.
