Abstract

一种支架型滤过器,它有由数根细钢丝和“Z”字环式粗钢丝焊接成滤过部,取出勾焊接在滤过部细钢丝的一端,其特征是:滤过部的开口端均为弧形状,细钢丝的开口端间隔设有短勾。其优点是:采用支架体结构,利用弧端及短勾双重定位,增加了滤过器的稳定性;采取短勾结构,勾部位置不在滤过器的端部,不易刺伤下腔静脉血管,使用安全可靠。

Description

支架型滤过器
本实用新型属于一种介入医疗器具，特别是一种支架型滤过器。
滤过器是介入医疗中重要的医疗器具，主要用于治疗肺栓塞疾病，肺栓塞是一种发病急、致死率很高的常见病，多因肢体静脉血栓形成后栓子脱落所致。目前，滤过器的形式多种多样，但最实用的一种是可经皮下取出的暂时放置性滤过器，这种滤过器克服了永久性滤过器所致的下腔静脉狭窄或阻塞的缺点。但它还存在着易倾斜、移位和易造成下腔静脉穿孔等缺点。
本实用新型的目的在于：能够实现在静脉中稳固定位，消除易倾斜、移位和造成下腔静脉穿孔等缺点。
本实用新型的目的是这样实现的：它有由数根细钢丝和“Z”字环式粗钢丝焊接成滤过部，取出勾焊接在滤过部细钢丝的一端，其特征是：滤过部的开口端均为弧型状，细钢丝开口端间隔设短勾。从而靠弧状端及短钩实现双重定位，提高定位稳定性，又不易刺伤血管。
本实用新型和现有技术比较，具有如下优点：
1、采用支架体结构，利用弧端及短勾双重定位，增加了滤过器的稳定性。
2、采取短勾结构，勾部位置不在滤过器的端部，不易刺伤下腔静脉血管，使用安全可靠。
下面结合附图对本实用新型作进一步说明。
图1是本实用新型结构示意图。
图2是图1的右视图。
见图1、2，具体结构如下：10根细钢丝2一端焊接在一起，并焊接取出钩1，10根细钢丝2的另一端呈喇叭状，并和“Z”字环式粗钢丝4焊接成滤过部，滤过部前端为10个弧型5。有5根细钢丝2开口端加工成短勾3，它们与无短勾的细钢丝间隔开。
