Abstract

The invention discloses a repair balloon for treating thrombus and calcification lesion, which comprises a balloon body, a cutting piece, a guide tube and a collecting tube, the balloon body is provided with a first connecting section and two ends of the balloon body are opened, the cutting piece extends along the peripheral surface of the balloon body and is partially and fixedly connected with the periphery of the balloon body. The guide tube is communicated with the first connecting section of the balloon body, the converging tube is arranged on the outer surface of the guide tube in a sleeved mode, and the near end of the cutting piece is converged in the converging tube and can slide relative to the converging tube. The repairing balloon is small and ingenious in structure and high in applicability, damage to the blood vessel wall in the operation process can be reduced, the repairing balloon can smoothly pass through a tortuous blood vessel and reach a focus to implement cutting, the operation time is shortened, the use experience of a user is enhanced, the repair balloon for treating thrombus and calcification lesions can be popularized and applied in the technical field of medical instruments.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a repair balloon for treating thrombus and calcified lesions. Background technique

[0002] Intervention therapy is an emerging treatment method between surgery and medical treatment, including endovascular intervention and non-endovascular intervention. To put it simply, interventional therapy is to make tiny channels with a diameter of a few millimeters on the blood vessels and skin without exposing the lesion by surgery, or through the original pipeline of the human body, in the imaging equipment such as angiography machine, fluoroscopy machine, CT, MR, etc. Under the guidance of B-ultrasound, it is the least traumatic treatment method to treat the lesion locally.

[0003] Currently, cutting balloons used in interventional operations mainly have three structures. One is the cutting balloon, whose structural feature is that a blade is adhered to the surface of the bal...
