Abstract

本实用新型属于一种可弯曲性射频穿刺针，该穿刺针由射频套管针，可弯曲性穿刺针和射频针电极构成，射频套管针内部依次套装有可弯曲性穿刺针和射频针电极，射频针电极的针栓通过电线与射频仪器及仪器电源相连。通过设置可弯曲性穿刺针能够达到靶位穿刺准确不易损伤脊髓，具有结构简单，成本低，使该穿刺针直达病人病灶，穿刺靶位准确和不易损伤神经的优点。

Description

可弯曲性射频穿刺针
技术领域
本实用新型属于医疗器械技术领域，具体涉及一种可弯曲性射频穿刺针。 
背景技术
目前，在射频介入治疗椎间盘突出以及肿瘤中常见的穿刺针为直型穿刺针，当病人的病灶在椎间盘后缘中央型突出时，直型穿刺针无法直达病灶，现有医生穿刺破硬脊膜给病人带来不必要的痛苦，易损伤脊髓，轻则无法治疗疾病，重则会造成瘫痪或有生命危险。 
发明内容
本实用新型的目的在于克服现有技术中存在的不足，而提供一种直针穿刺然后置入弯针，可随意调整针尖方向，穿刺准确不会损伤脊髓的可弯曲性射频穿刺针。 
本实用新型的目的是这样实现的：该穿刺针由射频套管针，可弯曲性穿刺针和射频针电极构成，射频套管针内部依次套装有可弯曲性穿刺针和射频针电极，射频针电极的针栓通过电线与射频仪器及仪器电源相连。所述可弯曲性穿刺针为金属制品。 
按照上述方案制成的可弯曲性射频穿刺针，通过设置可弯曲性穿刺针能够达到靶位穿刺准确不易损伤脊髓，具有结构简单，成本低，使该穿刺针直达病人病灶，穿刺靶位准确和不易损伤神经的优点。 
附图说明
图1为本实用新型的结构示意图。 
图2为本实用新型使用直型穿刺针时的结构示意图。 
具体实施方式
如图1、2所示，本实用新型为可弯曲性射频穿刺针，该穿刺针由射频套管针1，可弯曲性穿刺针2和射频针电极3构成，射频套管针1内部依次套装有可弯曲性穿刺针2和射频针电极3，射频针电极3的针栓4通过电线5与射频仪器7及仪器电源6相连。所述可弯曲性穿刺针2为金属制品。使用本实用新型时，首先，寻找病人的病灶位置，将与射频套管针1套装在一起的直型穿刺针芯8刺入髓核内，取出直型穿刺针芯8；然后，将可弯曲性穿刺针2置入射频套管针1中，由于可弯曲性穿刺针2具有良好的柔软性及弯曲性，因此可以准确方便的找到病人的病灶且不会损伤脊髓，达到靶位穿刺的目的；最后，将射频针电极3插入可弯曲性穿刺针2内，连通射频仪器7及仪器电源6即可。所述射频套管针1的表面涂覆有绝缘层或者在射频套管针1靠近针头0.5毫米处裸露其余部分涂覆有绝缘层。
