Abstract

本实用新型公开了一种微创手术介入导管内置针刀,由针刀头、介入导管、内导丝、固定顶丝钮、刻度尺线、后防滑手柄、前防滑手柄组成;采用在介入导管前部内置针刀头,使用前配合电子成像、冷光源、电凝系统,先将针刀头内缩入介入导管内部,将介入导管插入人体内,通过控制前置手柄和前置手柄,带动内导丝和针刀头实施切割操作,内导丝上的刻度尺线便于控制针刀头探出介入导管外的长度,具有操作简单,安全可靠的优点,是微创手术中理想的手术器械。

Description

一种微创手术介入导管内置针刀
技术领域
本发明涉及手术器械的技术领域,尤指一种微创手术介入导管内置针刀。 
背景技术
微创手术是应用现代先进的电子成像、冷光源、电凝系统等多种技术,以电子镜成像代替肉眼直视,以细长腔镜器械代替传统手术刀,力求以最小的切口路径,完成对体内病灶的诊断和治疗。随着微创医学技术的的发展,微创手术器械也在不断地创新出现。然而,在做特殊要求的微创手术时,如遇需要使用针刀时,而传统的手术针刀则不适合使用,给手术带来一定的不便之处。 
发明内容
本发明一种微创手术介入导管内置针刀,采用在介入导管前部内置针刀头,由前置手柄和后置手柄控制,实现微创手术腔内切割之目的。 
为了实现上述目的,本发明的技术解决方案是:一种微创手术介入导管内置针刀由针刀头、介入导管、内导丝、固定顶丝钮、刻度尺线、后防滑手柄、前防滑手柄组成;介入导管前部设置针刀头,介入导管后部与前防滑手柄连接,介入导管内部设置内导丝,内导丝前部与针刀头连接、后部穿过前防滑手柄与后防滑手柄连接,介入导管与后防滑手柄连接处的内导丝上设有刻度尺线,即为种微创手术介入导管内置针刀。 
本发明有益效果是:使用前配合电子成像、冷光源、电凝系统,先将针刀头内缩入介入导管内部,将介入导管插入人体内,通过控制前置手柄和前置手柄,带动内导丝和针刀头实施切割操作,内导丝上的刻度尺线便于控制针刀头探出介入导管外的长度,具有操作简单,安全可靠的优点,是微创手术中理想的手术器械。 
附图说明
下面结合附图和具体实施方式对本发明进一步描述。 
附图为一种微创手术介入导管内置针刀示意图。 
图中:1、针刀头,2、介入导管,3、内导丝,4、固定顶丝钮,5、刻度尺线,6、后防滑手柄,7、前防滑手柄。 
具体实施方式
由附图所示,一种微创手术介入导管内置针刀由针刀头1、介入导管2、内导丝3、 固定顶丝钮4、刻度尺线5、后防滑手柄6、前防滑手柄7组成;介入导管2前部设置针刀头1,介入导管2后部与前防滑手柄7连接,介入导管2内部设置内导丝3,内导丝3前部与针刀头1连接、后部穿过前防滑手柄7与后防滑手柄6连接,介入导管2与后防滑手柄6连接处的内导丝3上设有刻度尺线5,即为种微创手术介入导管内置针刀。 
以上所述,实施方式仅仅是对本发明的优选实施方式进行描述,并非对本发明的范围进行限定,在不脱离本发明技术的精神的前提下,本领域工程技术人员对本发明的技术方案作出的各种变形和改进,均应落入本发明的权利要求书确定的保护范围内。
