The cutting saccule mainly utilizes the saccule with a miniature blade to expand and cut atherosclerotic plaques on the inner wall of a blood vessel, and can generally achieve satisfactory effect on the cutting saccule for a narrow blood vessel which cannot be expanded by a conventional saccule.
When the saccule is pre-expanded, the injury to the blood vessel is irregular, which often causes excessive injury or blood vessel interlayer, and the cutting saccule can concentrate the expansion force of the saccule on the blade fixed on the surface of the saccule, so that the stenotic blood vessel can be expanded by generating less injury to the blood vessel. Because of the force gathering expansion effect, the cutting saccule can expand a diseased blood vessel by using expansion pressure smaller than that of a common saccule generally, in the prior art, the cutting saccule mainly adopts the design of installing blades on a base and then bonding the base on the outer circumferential surface of the saccule, the structure and the process of the cutting saccule are complex due to the design, and the risk of infirm fixation of the blades and the outer surface of the saccule exists. Since the blades are fixed on the outer surface of the balloon, the contraction of the flaps of the balloon can be influenced, and the risk that the blades scratch the balloon exists.
