Abstract

本实用新型涉及一种剪切型活检钳钳头，由铰接在钳头架(3)上的左钳头(1)和右钳头(2)组成，其特征在于：右钳头(2)的刃口(2－1)大于左钳头(1)的刃口(1－1)。采用本实用新型后，夹取人体组织取样时，左钳头的小刃口可以顺着右钳头的大刃口切进去，类似于剪刀原理，将组织纤维切断，这样，医生只要花很小的力就可以完成活组织取样，十分轻松地实现取样的目的。

Description

剪切型活检钳钳头
技术领域
本实用新型涉及医疗器械中的内窥镜活检钳，具体地说，涉及一种剪切型活检钳钳头。主要用于内窥镜下活组织取样检验，为内窥镜室必备器械之一。
背景技术
现有技术中的内窥镜活检钳钳头由左右两个刃口相平的钳头组成，在工作时，两钳头刃口碰到时即停止运动。由于人体组织纤维比较柔软，这种方法很难将纤维组织切断，医生在夹取组织时需花费很大的力，给治疗过程带来麻烦。
发明内容
本实用新型的目的是提供一种能使活检钳轻松夹取人体组织的剪切型活检钳钳头。
实现上述目的的技术方案是：一种剪切型活检钳钳头，由铰接在钳头架上的左钳头和右钳头组成，右钳头的刃口大于左钳头的刃口。
采用上述技术方案后，由于左右钳头的刃口大小不同，夹取人体组织取样时，左钳头的小刃口可以顺着右钳头的大刃口切进去，类似于剪刀原理，将组织纤维切断，这样，医生只要花很小的力就可以完成活组织取样，十分轻松地实现取样的目的。
附图说明
图1为本实用新型的结构示意图(钳口闭口状态)；
图2为本实用新型在钳口张开状态下的结构示意图；
图3为本实用新型的左钳头的结构示意图；
图4为本实用新型的左钳头的结构示意图。
具体实施方式
下面结合附图和实施例对本实用新型作进一步详细的说明。
如图1～4所示，一种剪切型活检钳钳头，由铰接在钳头架3上的左钳头1和右钳头2组成，右钳头2的刃口2-1大于左钳头1的刃口1-1。
本实用新型的工作原理如下：夹取人体组织取样时，左钳头1的小刃口1-1可以顺着右钳头2的大刃口2-1切进去，类似于剪刀原理，将组织纤维切断，这样，医生只要花很小的力就可以完成活组织取样，十分轻松地实现取样的目的。
当然，也可以采用左钳头的刃口大于右钳头的刃口的结构，其工作原理完全一样，也属于本实用新型保护的范围。
