Abstract

本实用新型涉及一种直肠活检使用的钩针,尤其是一种直肠检查器械。提供了一种结构简单,操作简便的直肠检查器械。其包括针把1和针体,直肠检查器械包括左针2和右针4,左针2和右针4的截面分别为半径相等的半圆形,左针2和右针4合并后为一圆柱体,左针2的顶端设有勺状弯钩3,左针2和右针4合并时,右针4的顶端与弯钩3相吻合。采用上述结构以后,由于左针2和右针4合并时,右针4的顶端与弯钩3相吻合,因此,在用左针的弯钩取出组织后,将左针和右针合并,再将整个针体取出,能够在取出针体时将所取组织保护在左针和右针闭合的弯钩内不损伤。

Description

直肠检查器械
一、技术领域:本实用新型涉及一种直肠活检使用的钩针,尤其是一种直肠检查器械。
二、背景技术:现有技术中,检查使用的器械在组织取出时容易损伤组织,或者在取出时损伤的创伤面较大。
三、发明内容:本实用新型的目的在于提供一种结构简单,操作简便,在取出组织时能够将所取组织保护完好的直肠检查器械。本实用新型的技术方案是:直肠检查器械包括针把1和针体,直肠检查器械包括左针2和右针4,左针2和右针4的截面分别为半径相等的半圆形,左针2和右针4合并后为一圆柱体,左针2的顶端设有勺状弯钩3,左针2和右针4合并时,右针4的顶端与弯钩3相吻合。采用上述结构以后,由于左针2和右针4合并时,右针4的顶端与弯钩3相吻合,因此,在用左针的弯钩取出组织后,将左针和右针合并,再将整个针体取出,能够在取出针体时将所取组织保护在左针和右针闭合的弯钩内不损伤,也不易滑落,且边缘固定,易于病理检查。右针4的顶端与弯钩3吻合时,对未切割不完全的组织起到二次切割的作用。
四、附图说明:附图为本实用新型的结构示意图。
五、具体实施例:如图所示:直肠检查器械包括针把1和针体,直肠检查器械包括左针2和右针4,左针2和右针4的截面分别为半径相等的半圆形,左针2和右针4合并后为一圆柱体,左针2的顶端设有勺状弯钩3,左针2和右针4合并时,右针4的顶端与弯钩3相吻合。
