Abstract
(EN) The present invention relates to an interventional medical instrument, comprising a plurality of wavy annular structures, which are arranged at intervals in an axial direction, and characterized in that each wavy annular structure comprises a plurality of support rods, which are connected end to end; at least one support rod is provided with a deconstruction unit; a through hole is formed in the deconstruction unit, such that a deconstruction part is formed on the support rod; and an acute angle is formed between a connecting line of two points with the largest distance of the through hole and an extension direction of the support rod. The interventional medical instrument can provide a support function and can alleviate the restraining effect on a lumen.
(FR) La présente invention concerne un instrument médical d'intervention, comprenant une pluralité de structures annulaires ondulées, qui sont disposées à des intervalles dans une direction axiale, et caractérisées en ce que chaque structure annulaire ondulée comprend une pluralité de tiges de support, qui sont connectées bout à bout ; au moins une tige de support est pourvue d'une unité de déconstruction ; un trou traversant est formé dans l'unité de déconstruction, de telle sorte qu'une partie de déconstruction est formée sur la tige de support ; et un angle aigu est formé entre une ligne de connexion de deux points avec la plus grande distance du trou traversant et une direction d'extension de la tige de support. L'instrument médical d'intervention peut fournir une fonction de support et peut atténuer l'effet restrictif sur une lumière.
(ZH) 本发明涉及一种介入式医疗器械,包括多个沿轴向间隔排列的波形环状结构,其特征在于,每个所述波形环状结构包括多个首尾相连的支撑杆,至少一个支撑杆上具有解构单元,所述解构单元上开设有通孔使所述支撑杆上形成解构部位,且所述通孔的距离最大的两个点的连线与所述支撑杆的延伸方向的角度为锐角。该介入式医疗器械能够起到支撑作用,且能减缓对管腔的束缚作用。
