Description

手柄枢轴结构
技术领域
本发明涉及一种医用闭合器的手柄枢轴结构，属于医疗器械领域。
背景技术
目前，对食道、胃、肠道等生理组织进行外科手术吻合时，经常使用外科手术闭合器进行吻合，其中，医用直线型闭合器是较为重要的一种。然而，在实际生产或运输过程中，医用直线型闭合器的手柄与支架的枢轴销经常会脱落，导致器械还未使用就报废，造成了很大的麻烦。
发明内容
本发明的目的在于解决上述的技术问题，提供一种结构简单安全的手柄枢轴结构。
本发明的目的通过以下技术方案来实现：
一种手柄枢轴结构，包括：销及设置在手柄上与所述销枢轴配接的圆孔，其特征在于：所述销上设有一个周向凹槽，所述圆孔上设有一个U形缺口及与该U形缺口对应的断口，所述销的直径大于所述圆孔的直径。
优选的，所述周向凹槽的直径等于或小于所述圆孔的直径。
优选的，所述U形缺口与断口位于同一条直线上，所述U形缺口设置在圆孔靠近手柄内腔的一侧，所述断口设置圆孔远离手柄内腔的一侧。
本发明的有益效果主要体现在：能够有效地防止枢轴销脱落，结构简单实用。
附图说明
下面结合附图对本发明技术方案作进一步说明：
图1：本发明手柄枢轴结构的爆炸示意图。
图2：本发明手柄枢轴结构组装后的剖视图。
具体实施方式
本发明揭示了一种医用闭合器的手柄枢轴结构，如图1所示，包括销1及设置在手柄2上与所述销1枢轴配接的圆孔3，所述销1上设有一个周向凹槽4。所述圆孔3设置在一手柄2的固定片7上，所述固定片7设于手柄2的内部，且向外延伸。
所述圆孔3上设有一个U形缺口5及与该U形缺口对应的断口6，所述U形缺口5与断口6位于同一条直线上，所述U形缺口5设置在圆孔3靠近手柄2内腔的一侧，所述断口6设置圆孔3远离手柄2内腔的一侧，且使所述固定片7的最外侧分叉。
所述销1的直径大于所述圆孔3的直径。所述周向凹槽4的直径等于或小于所述圆孔3的直径。
装配中，通过断口6可以使所述固定片7在微张的情况下装入销1，然后在U形缺口5的作用下，该固定片7在适当变形情况下也不会裂开，即增大了固定片的弹性变形能力。而当销1装入圆孔3中后，如图2所示，周向凹槽4与圆孔3配接，而销1的直径大于所述圆孔3的直径，使销1不能左右滑动，即不会轻易脱落。
本发明尚有多种具体的实施方式，凡采用等同替换或者等效变换而形成的所有技术方案，均落在本发明要求保护的范围之内。
