Description

一种脊椎用填充器
技术领域： 本实用新型涉及的是一种手术用的医疗器械， 尤其是一种适合粉碎性骨折 的脊椎用填充器。 背景技术： 在现有技术中， 公知的技术是本申请人在国家知识产权局专利局申请的
200820173700. 0号专利， 该专利公开了一种用于压縮性骨折手^:的扩张、 填充 器， 这种填充器是由导管和固定导管的导管座， 在导管内腔有导针， 该导针固 定在导针座上， 在导管的端部有料袋， 所述的料袋与导管之间是靠料袋的连接 头与导管连接， 而连接头与导管的连接一般是靠螺纹连接的， 这样的连接在手 术完成后要想将使料袋与导管分离就必须旋转导管，增加了手术的难度，另外， 还要将连接头留在人体内， 这是现有技术所存在的不足之处。 发明内容： 本实用新型的目的， 就是针对现有技术所存在的不足， 而提供两种脊椎用 填充器的技术方案， 该方案的料袋是靠外套管套在导管的外壁上， 这样在手术 完成后， 只要抽出导管和外套管即可完成， 方便了手术， 在人体内也不需留有 无用的异物。
本方案是通过如下技术措施来实现的：
第一种技术方案的脊椎用填充器， 包括有导管和固定导管的导管座， 在导 管内腔有导针， 该导针固定在导针座上， 在导管的端部有用柔软并符合生物相 容性非金属材质或者可吸收材质制成的密封或透气的料袋， 本方案的特点是在 述的导管外还套有外套管， 该外套管固定在外套管座上， 外套管座则与导管
- 1 - 确认本 座之间有可拆装的连接， 在所述外套管的开口端有锥形外套管缩径锥台连接小 直径外套管； 所述的导管在外套管缩径锥台处有与外套管缩径锥台对应的导管 缩径锥台， 导管缩径锥台连接有小直径导管； 所述料袋由开口端套在导管上， 位于外套管与导管之间并由外套管箍紧在导管的外壁上。 本方案的具体特点还 有，所述小直径导管的长度为 1-40毫米。所述小直径外套管的长度为 0-10毫米。 所述料袋的长度在 10-50毫米之间。所述的料袋是单层。所述的料袋是在料袋外 壁还有料袋保护层。 所述的外套管座与导管座之间可拆装的连接是螺纹连接。
第二种技术方案的脊椎用填充器， 包括有导管和固定导管的导管座， 在导 管内腔有导针， 该导针固定在导针座上， 在导管的端部有用柔软并符合生物相 容性非金属材质或者可吸收材质制成的密封或透气的料袋， 本方案的特点是在 所述的导管外还套有外套管， 该外套管固定在外套管座上， 外套管座则与导管 座之间有可拆装的连接， 在所述外套管的开口端有外套管内凸台； 所述的导管 在外套管内凸台处有与外套管内凸台对应的导管缩径锥台， 导管缩径锥台连接 有小直径导管； 所述料袋由开口端套在导管上， 位于外套管与导管之间并由外 套管箍紧在导管的外壁上。 本方案具体的特点还有， 所述小直径导管的长度为 1-40毫米。 所述外套管内凸台的长度为 0. 5〜10毫米。 所述料袋的长度在 10 - 50 毫米之间。 所述的料袋是单层。 所述的料袋是在料袋外壁还有料袋保护层。 所 述的外套管座与导管座之间可拆装的连接是螺纹连接。
两种方案的有益效果可根据对上述两方案的叙述得知， 由于在这两种结构 中， 所述的料袋均是靠外套管套在导管的外壁上， 在手术时通过导管可向料袋 注入骨水泥等骨材料， 来支撑患部脊椎。 当在手术完成后， 只要将导管和外套 管一并抽出即可完成手术， 这既方便了手术操作， 同时在人体内也不需留有无 用的异物。 两种方案的区别仅在于限制料袋不能自由滑动的结构。 第一种方案 采用的是在外套管的开口端有锥形外套管缩径锥台连接小直径外套管， 而导管 在外套管縮径锥台处有与外套管缩径锥台对应的导管缩径锥台， 导管缩径锥台 连接有小直径导管。 第二种方案采用的是在外套管的开口端有外套管内凸台， . 而导管在外套管内凸台处有与外套管内凸台对应的导管縮径锥台， 导管缩径锥 台连接有小直径导管。 两种方案也均是采用料袋在移动时要变径， 以此来限制 料袋不能自由移动。 由此可见， 本实用新型与现有技术相比， 具^ "实质性特点 和进步， 其实施的有益效果也是显而易见的。
