Description

肿瘤消融针精准定位套管
技术领域
本发明涉及医用器具领域，尤其涉及肿瘤消融针精准定位套管。
背景技术
肿瘤是危害人类健康的常见恶性疾病，近年来，以射频消融技术和微波消融技术为代表的局部消融治疗技术迅速发展，射频消融(Radiofrequency ablation,RFA)是一种热凝固疗法，它是利用波长460～500kHz的射频交变电流，通过射频电极针使其周围组织中的带电粒子高速振荡摩擦产热，温度可达50～110℃，致电极周围肿瘤细胞发生凝固性坏死，从而灭活肿瘤细胞的一种微创治疗新方法。微波消融是利用微波能作用组织即刻产生热效应，在数分钟的时间内，形成稳定的类球形热场，中心温度大于100℃，边缘大于60℃，肿瘤组织在高温下瞬间被凝固灭活，进而逐步消融达到治疗目的。
现有的肿瘤消融针广泛应用于治疗肝、肺、肾、前列腺、胰腺、子宫肌瘤等各种实体肿瘤等疾病，但在脑肿瘤的治疗应用中还存在较多的问题和风险，由于消融针是金属的，定位有伪影，会造成干扰，因此不能精准定位，对于脑部的定位，稍有偏差可能会导致患者死亡，为确保脑肿瘤的完全消融，消融针的位置至关重要，然而对于脑部肿瘤的定位和治疗一直未有很好的解决方法。
此外，对于消融针的位置是否合适，需要在穿刺后进行CT或MRI下显影以确定消融针位置，传统消融术病人需携带消融针进行CT或MRI，容易在过程中损伤周围组织，对脑部造成二次伤害，存在安全隐患。
发明内容
本发明的目的在于解决现有技术中的上述问题，提供肿瘤消融针精准定位套管，可精准定位以对患者实施治疗，尤其是针对脑部肿瘤具有精准的定位作用。
为达到上述目的，本发明采用如下技术方案：
肿瘤消融针精准定位套管，包括套管本体，所述套管本体用于套设肿瘤消融针的电极针主体，且套管本体与电极针主体活动连接；套管本体整体采用耐高温材料，且耐高温材料中含有在CT、MRI下显影的显影剂。
所述耐高温材料采用耐高温度200℃的塑料材料。
所述套管本体的尖端呈封闭式、开放式两种。
所述套管本体的长度为3～15cm各种规格，直径0.1～2.0cm各种规格。
相对于现有技术，本发明技术方案取得的有益效果是：
1、本发明的套管本体采用耐高温的塑料材料，其该材料中含有可在CT、MRI下显影的显影剂，因此可精准定位，尤其是对脑部肿瘤具有精准的定位作用。
2、本发明的套管本体与电极针主体活动连接，定位或治疗后，可将套管本体滞留在组织内，以避免对患者的二次伤害。
3、本发明可根据不同的肿瘤消融针制作不同规格的套管，定位和治疗不同类型的肿瘤，适用范围广。
附图说明
图1为本发明的结构示意图。
具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明做进一步详细说明。
如图1所示，本实施例包括套管本体，所述套管本体用于套设肿瘤消融针的电极针主体，且套管本体与电极针主体活动连接，具体地，套管本体通过一连接部与肿瘤消融针的手柄处采用螺纹连接或卡接等拆卸式的连接方式。
所述套管本体整体采用耐高温材料，且耐高温材料中含有在CT、MRI下显影的显影剂，具体地，所述耐高温材料采用耐高温度200℃的塑料材料，可对脑部肿瘤精准定位。
所述套管本体的尖端呈封闭式、开放式两种，电极针主体可露出于套管本体或不露出套管本体。
所述套管本体的长度为3～15cm各种规格，直径0.1～2.0cm各种规格，可根据不同的肿瘤消融针制作不同规格的套管，定位和治疗不同类型的肿瘤，适用范围广。
本发明的使用方法和工作原理如下：
本发明的肿瘤精准定位套管分为尖端封闭式、尖端开放式两种，作为肿瘤消融针的外套管，与肿瘤消融针一起插入肿瘤，进行消融毁损肿瘤，肿瘤精准定位套管在CT、MRI上显影，能够精准定位。
