Embodiment Construction
[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many other different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0038] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for pur...

The invention discloses a high-adaptability interventional catheter, which comprises a catheter structure, a balloon, an annular electrode, a conducting wire and a laser optical fiber, wherein the catheter structure is provided with a liquid input channel, a conducting wire leading-in channel and an optical fiber placement channel, the balloon is connected to one end of the catheter structure in a sealed and sleeved mode, the balloon is communicated with the liquid input channel and the wire leading-in channel, the annular electrode is arranged on the catheter structure in a sleeving mode and wrapped by the balloon, the conducting wire is arranged in the conducting wire leading-in channel in a penetrating mode and electrically connected to the annular electrode, and the laser optical fiber is arranged in an optical fiber mounting channel and is exposed from one end, provided with the balloon, of the catheter structure. According to the invention, when the high-adaptability interventional catheter passes through a blood vessel, obstacles can be cleared away for smooth passing of the balloon on the basis of the arrangement and the function of the laser optical fiber, and the passing action cannot be affected even if the catheter faces serious calcified tissue, so that the high-adaptability interventional catheter has ultrahigh blood vessel passing capacity and is high in applicability.
Description
Technical field [0001] The present invention relates to the technical field of medical devices, and in particular to a highly adaptable interventional catheter. Background technique [0002] Calcified tissue is a harmful substance caused by the deposition of fat, thrombus, connective tissue and calcium carbonate on the inner walls of arteries. Calcified tissue blocking blood vessels is one of the main causes of cardiovascular disease. The blockage of calcified tissue in the blood vessels will reduce the inner diameter of the blood vessels, resulting in reduced blood flow velocity and poor blood flow, thereby hindering or even blocking the flow of blood, resulting in insufficient blood and oxygen supply to the body. Poor blood flow leads to increased internal pressure in blood vessels, which can easily induce various cardiovascular diseases. In severe cases, it can cause arterial rupture and cause large-scale bleeding. The higher the degree of arterial stenosis, the greater ...
