Description

Driven end clamp holder for drug coating balloon catheter spraying equipment Technical Field The utility model relates to the technical field of ultrasonic spraying machines, in particular to a driven end clamp holder for a drug coating balloon catheter spraying device. Background In the field of cardiovascular interventional devices, drug coated balloon catheters (DCBs) are used as a new generation of interventional therapy, which release drugs through a surface coating to prevent restenosis of the blood vessel, where the uniformity and integrity of the surface drug coating is directly related to the therapeutic effect. In the spraying process, the driven end clamp needs to stably clamp the guide pipe and drive the guide pipe to rotate at a constant speed so as to realize uniform coverage of the coating material. Because the whole length of the balloon catheter is longer, and the balloon catheters of different types have larger difference in diameter, length and the like, the spraying equipment can only clamp part of the balloon catheter during spraying, and the rest part of the balloon catheter can be wound in the spraying process to influence the spraying quality. The Chinese patent with the prior art publication number of CN221311155U discloses a catheter containing mechanism and an ultrasonic balloon spraying machine, which comprises a coil pipe tool, wherein the coil pipe tool comprises an upper cover and a main body tool, the upper cover is hinged to the edge of the main body tool, an end protrusion is arranged at the edge of the main body tool, a gland matched with the end protrusion is arranged at the edge of the upper cover, a spiral containing groove is arranged on the main body tool, an inlet end and an outlet end are arranged on the spiral containing groove, the outlet end is positioned on the end protrusion, and a rotating shaft mounting hole is arranged at the bottom of the main body tool. However, the above technical scheme is that the width of the spiral accommodating groove is fixed, so that only balloon catheters with fixed specifications can be accommodated, the adaptability of balloon catheters with different specifications is poor, and when balloon catheters with different diameters are replaced, the whole coil pipe tool is required to be replaced, so that the whole spraying efficiency is affected. Disclosure of utility model In order to solve the defects that only balloon catheters with fixed specifications can be stored in the prior art, the adaptability of balloon catheters with different specifications is poor, and when balloon catheters with different diameters are replaced, the whole coil pipe tool is required to be replaced, so that the whole spraying efficiency is affected, the utility model provides a driven end clamp for a drug coating balloon catheter spraying device.
