Abstract

本发明公开了一种取石网篮,包括手柄、导丝、鞘管、网篮;所述导丝穿过鞘管和鞘管一端的网篮连接;所述鞘管另一端设置手柄;所述的网篮由单根镍钛记忆合金丝围成螺旋形结构;所述螺旋形结构的网篮外形呈圆锥形。本发明设计这款将网篮设计成螺旋状,网篮的端部收起时可以有效地拦住石头,在收起时,由于网篮由单根镍钛记忆合金丝围成螺旋形结构,可以方便将丝推直收起,取出网篮中包裹的石块,也可以放开,不影响网篮顺利收起。

Description

一种取石网篮
技术领域
本发明涉及取石网篮。
背景技术
目前,临床使用的取石网篮一般为勺型还是橄榄型,在结石漂移时,容易包裹结石小颗粒造成网篮在收起时,不能顺利收起。我们设计这款将网篮设计成螺旋状。端部收起可以有效地拦住石头,在收起时,由于单根丝状螺旋网篮,可以方便将丝推直收起,取出网篮中包裹的石块,也可以放开,不影响网篮顺利收起。
发明内容
针对上述现有技术的不足之处,本发明解决的问题为:取石网篮一般为勺型还是橄榄型,在结石漂移时,容易包裹结石小颗粒造成网篮在收起时,不能顺利收起。
为解决上述问题,本发明采取的技术方案如下:
一种取石网篮,包括手柄、导丝、鞘管、网篮;所述导丝穿过鞘管和鞘管一端的网篮连接;所述鞘管另一端设置手柄;所述的网篮由单根镍钛记忆合金丝围成螺旋形结构;所述螺旋形结构的网篮外形呈圆锥形。
进一步,所述的鞘管为尼龙编织管。
进一步,所述的手柄由PP材料制成。
本发明的有益效果
本发明设计这款将网篮设计成螺旋状,网篮的端部收起时可以有效地拦住石头,在收起时,由于网篮由单根镍钛记忆合金丝围成螺旋形结构,可以方便将丝推直收起,取出网篮中包裹的石块,也可以放开,不影响网篮顺利收起。
附图说明
图1为本发明的结构示意图。
图2为本发明中网篮的放大结构示意图。
具体实施方式
下面结合附图对本发明内容作进一步详细说明。
如图1和2所示,一种取石网篮,包括手柄1、导丝、鞘管2、网篮3。所述导丝穿过鞘管2和鞘管2一端的网篮3连接。所述鞘管2另一端设置手柄1。所述的网篮3由单根镍钛记忆合金丝围成螺旋形结构。所述螺旋形结构的网篮外形呈圆锥形。进一步优选,所述的鞘管2为尼龙编织管。进一步优选,所述的手柄1由PP材料制成。
本发明设计这款将网篮3设计成螺旋状,网篮3的端部收起时可以有效地拦住石头,在收起时,由于网篮3由单根镍钛记忆合金丝围成螺旋形结构,可以方便将丝推直收起,取出网篮中包裹的石块,也可以放开,不影响网篮顺利收起。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
