Abstract

本发明涉及一种医疗器械,特别是涉及一种双杆扩压式手术插管扩持器。它由内扩杆、杆座、钳柄、铆钉、锯齿卡和握柄构成。其中,条状的钳柄与椭圆环状的握柄的长轴互成一钝角且为一整体。一对钳柄和握柄通过铆钉连接,每个握柄的内侧各有一与握柄为一整体的锯齿卡。每个钳柄的端部有一与钳柄垂直且与钳柄为一整体的圆柱形的杆座,杆座的端部有与杆座为一整体的内扩杆。内扩杆的直径为杆座的1/2,长度为杆座的2-3倍。本发明不仅能牢固固定插管,而且能将插管送入到较深部位,大大提高了手术的准确性和稳定性。

Description

双杆扩压式手术插管扩持器
技术领域
本发明涉及一种医疗器械,特别是涉及一种双杆扩压式手术插管扩持器。
背景技术
在心脏或大血管手术中,常常需要对血管进行插管,目前的操作中全是以手直接拿管子进行插管,在对于深部操作时,手无法伸进切口深部。此时,由于管子比较软,而手持部位离管尖较远,插管的准确性大受影响。
发明内容
本发明为解决现有技术的不足,提供一种能稳定夹持插管的双杆扩压式手术插管扩持器。
解决本发明技术问题的方案是:双杆扩压式手术插管扩持器由内扩杆、杆座、钳柄、铆钉、锯齿卡和握柄构成。其中,条状的钳柄与椭圆环状的握柄的长轴互成一钝角且为一整体。一对钳柄和握柄通过铆钉连接,铆钉位于钳柄和握柄交界处。每个握柄的内侧各有一与握柄为一整体的锯齿卡,两锯齿卡相对的一侧面上有可相互扣合的齿。每个钳柄的端部有一与钳柄垂直且与钳柄为一整体的圆柱形的杆座,杆座的端部有与杆座为一整体的内扩杆。内扩杆的直径为杆座的1/2,长度为杆座的2-3倍。
采用上述方案,能达到以下效果:
在使用时,本发明的两内扩杆可从插管的口部伸入插管中,通过手对两握柄的握捏和两锯齿卡的扣合固定,利用两内扩杆对插管内壁的侧向压力所产生的摩擦力固定插管。因此本发明不仅能牢固固定插管,而且能将插管送入到较深部位,大大提高了手术的准确性和稳定性。
附图说明
图1为本发明的结构示意图;
图2为内扩杆、杆座和钳柄的结构放大示意图。
图中:1.内扩杆  2.杆座  3.钳柄  4.铆钉  5.锯齿卡  6.握柄
具体实施方式
下面结合附图和实施例对本发明作进一步的描述。
双杆扩压式手术插管扩持器由内扩杆1、杆座2、钳柄3、铆钉4、锯齿卡5和握柄6构成。其中,条状的钳柄3与椭圆环状的握柄6的长轴互成一钝角且为一整体。一对钳柄3和握柄6在钳柄3和握柄6交界处通过铆钉4连接,每个握柄6的内侧上各有一个与握柄6为一整体的锯齿卡5,两锯齿卡5相对的一侧面上有可相互扣合的齿。每个钳柄3的端部有一与钳柄3垂直且与钳柄3为一整体的圆柱形的杆座2,杆座2的端部有与杆座2为一整体的内扩杆1。内扩杆1的直径为杆座2的1/2,长度为杆座2的3倍。
