技术领域technical field
本发明涉及医疗器械领域，尤其涉及一种多段可控弯曲的介入导管。The invention relates to the field of medical devices, in particular to a multi-segment controllable bending intervention catheter.
背景技术Background technique
随着介入诊疗越来越多，对介入导管需求及功能也要求越来越多。由于血管粗细直径不同，各科室所做的介入手术面临的血管直径也不同。不同直径的血管在分叉时，有不同的转弯半径尺寸要求。如介入导管工作头部的转弯半径太大，则进不了这血管分叉，或者勉强进入但会对血管壁造成很大的摩擦损伤；如果导管转弯半径小而遇到的血管很粗，则有可能这导管弯曲的头部勾不住血管的分叉口，在这血管分叉处滑脱而没进入；有的时候血管有可能由粗到细，如何能够适应各种血管转弯半径及弯曲弧度的要求，以及更好的减少摩擦损伤是目前要求解决的问题。With more and more interventional diagnosis and treatment, there are more and more requirements for interventional catheters and functions. Due to the different thickness and diameter of blood vessels, the diameters of blood vessels faced by interventional operations performed by various departments are also different. Vessels with different diameters have different turning radius requirements when they bifurcate. If the turning radius of the working head of the interventional catheter is too large, the bifurcation of the blood vessel cannot be entered, or it will cause great friction damage to the vessel wall if it is barely entered; if the turning radius of the catheter is small and the blood vessel encountered is very thick, there is a Maybe the curved head of the catheter can't catch the bifurcation of the blood vessel, and slipped at the bifurcation of the blood vessel without entering it; sometimes the blood vessel may change from thick to thin, how can it adapt to various turning radii and curvature of the blood vessel? Requirements, as well as better reduction of friction damage is currently required to solve the problem.
