Abstract

The embodiment of the invention discloses a cutting balloon applied to the technical field of medical instruments. By employing the cutting balloon, a technical problem that blades of a conventional balloon are damaged due to large force when the conventional balloon cuts calcified lesions or other formed lesions having large hardness is solved, and the balloon can be prevented from reverse damage when the blades are heavily stressed. The cutting balloon provided in the embodiment comprises a balloon body and multiple rows of blades fixed to the outer surface of the balloon body in the axial direction. Every two adjacent blades are arranged in a spaced mode. Each blade comprises a tool nose and a tool apron which are integrally arranged, the thickness of the blade gradually increases from the tool nose to the tool apron, and the blade is directly fixed to the balloon body through the tool apron.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a cutting balloon. Background technique [0002] Interventional therapy is a minimally invasive treatment. It is guided by medical imaging equipment to make tiny channels with a diameter of several millimeters in the blood vessels and skin, or through the original pipes of the human body, using special precision instruments such as catheters and guide wires. , Introduced into the human body, diagnosis and local treatment of diseases in the body. Because of its advantages such as minimally invasive, safe, simple operation, good curative effect and quick effect, it has become the third largest clinical treatment method alongside medical treatment and surgical treatment. It has opened up new and effective treatments for many clinically incurable or refractory diseases, such as advanced cancer, arterial embolism, vascular stenosis, intrahepatic bile duct stones, etc. [0003] Ball...
