Description

新型PTCA球囊导管近端管连接装置
技术领域
本发明涉及一种医用导管连接装置,特别是一种新型的PTCA球囊导管近端管的连接装置。
背景技术
PTCA球囊导管近端管的连接装置是PTCA球囊导管装置的中枢部分,该连接装置的一端与PTCA球囊导管近端管连通,另一端则与注射器、加压装置等配套装置连通,是临床手术医师在实行手术操作时的定位手柄,也是导引导丝进出的定位和保护装置。临床手术医师在进行手术时,通过左手握住该连接装置,右手巧妙地控制导引导丝的进出,以及操纵其他配套连接装置,最终使球囊导管顺利到达患处,完成手术治疗。因此其形状、结构的设计对临床手术医师的操作手技成败至关重要,同时,其密封性能对球囊导管进入患处的性能控制也有很大影响,如其密封性能不好,导致无法控制球囊导管的压力性能,这些都必然加大手术的风险,直接关系到治疗的成败。目前所公知的PTCA球囊导管近端的连接装置,一般是一根比PTCA球囊近端管大的短圆管,它与较小的PTCA球囊近端管间有一段圆锥管过渡连接,目前对于短圆管的形状设计,以及短圆管与圆锥管如何能密封连接的设计方法也层出不穷,但至今无法从根本上解决问题。
发明内容
本发明的主要目的在于提供一种既能满足临床手术医师操作手技需求,又能满足其密封性能要求,结构简单、安全可靠的PTCA球囊导管近端管的连接装置。
本发明解决其技术问题所采用的技术方案是:一种PTCA球囊导管近端管的连接装置,是一个一体成型的呈圆锥状逐渐变细的短圆管,所述的短圆管的头部是具有内凹螺纹的大接头,与注射器、加压装置等配套装置连通;短圆管的尾部是具有内凹螺纹的小接头,与较小直径的球囊导管近端管连通,接口处还外套上一抗扭结保护套,以增加其密封性能;同时,短圆管体部靠近大接头处,向外突出两对称的板状椭圆形手柄,专为方便临床手术医师操作手技而设计,增加操作的灵活性。
根据以上的技术方案,本发明具有下列优点:
1.一种新型的PTCA球囊导管近端管的连接装置,通过简单的模具设计,即能制备出一体成形的呈圆锥状逐渐变细的短圆管,工艺简单。
2.短圆管体部靠近大接头处,具有专为方便临床手术医师操作手技而设计的向外突出两对称的板状椭圆形手柄,增加操作的灵活性。
3.一体成型的呈圆锥状逐渐变细的短圆管,不仅避免了短圆管再与圆锥管的过渡连接,而且大大增加了其密封性能,降低手术的风险。
附图说明
附图是本发明的PTCA球囊导管近端管的连接装置的结构示意图,其中标号1为一体成型的呈圆锥状逐渐变细的短圆管体部,标号2为大接头,标号3为小接头,标号4为向外突出的板状椭圆形手柄。
具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述:
一种新型的PTCA球囊导管近端管的连接装置,是通过简单的模具设计,制备出的一体成型的呈圆锥状逐渐变细的短圆管体部1,具有向外突出两对称的板状椭圆形手柄4、球囊导管近端管连通的内凹螺纹状小接头2,以及与注射器、加压装置等配套装置连通的内凹螺纹状大接头3。临床手术医师在进行手术时,通过左手握住该连接装置,右手巧妙地控制导引导丝的进出,以及操纵其他配套连接装置,最终使球囊导管顺利到达患处,完成手术治疗。本发明具有结构简单、操作简便、密封效果好等明显优点,满足了临床手术医师的需求,降低手术风险。
以上仅是本发明的具体应用范例,对本发明的保护范围不构成任何限制.除上述实施例外,本发明还可以有其他实施方式.凡采用等同替换或等效变换形成的技术,均落在本发明所要求保护的范围之内.
