挤出系统生产出直径仅为0.002英寸的医用导管

Guill Tool & Extrusion公司推出的MediFlow系统可用来挤出直径极小的导管,这些导管可应用于微创手术等医疗领域。
医用级挤出系统可生产出比人的头发还精细的导管。MediFlow系统的头模具和嵌入式模具专为导管的挤出加工设计,其最小公差仅为0.002英寸,可用于关节窥镜等领域。该设备于近期由Guill Tool & Engineering公司 (美国,美国罗德艾兰州,West Warwick; www.guill.com) 推出。

Guill公司将一系列技术整合进MediFlow系统中,以获得持久的高精度。系统已在其它工具制造中获得最佳性能。这些技术包括可减少滞留时间和压力的头部偏转设计,可平衡上下游热量并尽可能稳定流速的熔体端面螺旋专利设计和分流或单向流动进料。

这种被称为轻触式的设计可以方便地调节同心度,而不影响上游模流。这种轻触式装置和偏转器排列于一个普通轴杆上,可以消除公差叠加,缩短准备时间。

该系统的优点还包括可以调节胶体空间,以获得最佳温度控制;以及可为主模体选择筒状或带状加热器。

该系统还带有两个可调节的海波管尖,可缩短生产时间,降低成本。若管尖被损坏或轻微弯曲,操作者仅需更换插件,无需更换整个管尖。该操作一分钟左右即可完成。系统也提供单一管尖设计。
