Description

Technical Field

[0001] The utility model relates to the field of medical equipment and the technical field of cutting balloons, in particular to a flexible substrate composite cutting balloon anti-adhesion coating spraying tool. Background Art

[0002] The cutting balloon is a balloon with a special status in the field of coronary interventional treatment. It closely combines micro-cutting technology with traditional balloon dilatation, providing doctors with a new interventional treatment plan. During the lesion pretreatment process, the application of the cutting balloon can accurately cut and remove the stenotic lesions in the blood vessels, making the subsequent interventional treatment plan more complete and effective.

[0003] The cutting balloon is a special balloon used as a pretreatment measure in coronary intervention. The longitudinal axis of its surface is inlaid with blades at equal angles. These blades will cut the intima and media of the lesion when the balloon is expanded. Subsequently, due to the squeezing effect of the balloon during expansion, the proliferating intima tissue in the stent is pushed out of the stent frame structure. Therefore, the cutting balloon causes less damage to the blood vessel wall and causes less inflammatory reaction to the blood vessel wall, thereby reducing the incidence of postoperative restenosis.

[0004] The existing balloon coating spraying equipment can only spray a single balloon. After each spraying is completed, the equipment, materials, and tooling need to be readjusted, and continuous spraying cannot be performed, which wastes manpower and materials. It can only spray at a specific angle. When multi-angle spraying is required, different spraying equipment needs to be replaced, resulting in high equipment investment and low efficiency. In addition, the existing balloon coating spraying equipment also needs to be equipped with additional coating curing equipment, which is inconvenient to use. Utility Model Content
