一种痔吻合器
本技术涉及一种痔吻合器。
技术介绍
众所周知,肛管直肠部位的解剖时,神经、血管、淋巴等的走向是纵行分布,故肛管直肠部位手术的解剖应以纵行或以肛门为圆心向四周呈放射状为宜。而目前市场上已有的肛肠科器械(PPH、TST)均是以横行切除。因此而引起的诸多弊端及后遗症,比如肛门直肠狭窄、坠胀、吻合口多结节等。
技术实现思路
针对上述问题,本技术提供一种痔吻合器。本技术的技术方案是:一种痔吻合器,包括:活动手柄,包括上手柄和下手柄,所述上手柄与下手柄之间通过枢轴相互铰接,所述上手柄和下手柄的末端设置有定指圈,所述上手柄和下手柄之间固定设置有复位弹簧。吻合剪,包括上吻合剪和下吻合剪,所述上吻合剪与下手柄固定连接,所述下吻合剪与上手柄固定连接,所述上吻合剪和下吻合剪的端部设置有相互对应的上剪切刃和下剪切刃,所述上吻合剪和下吻合剪于上剪切刃和下剪切刃的相反位置设置有上环切刃和下环切刃,所述上环切刃和下环切刃为锯齿形刀刃。作为上述技术方案的进一步优化,所述上环切刃和下环切刃为锯齿形刀刃时,还包括斜切刃和拉切刃,所述拉切刃与上吻合剪或下吻合剪之间呈直角设置。作为上述技术方案的进一步优化,所述锯齿形刀刃处还设置有弧形的刃勾。作为上述技术方案的进一步优化,所述锯齿形刀刃的刃尖间距为5-8mm。作为上述技术方案的进一步优化,所述锯齿形刀刃中拉切刃的高度为3-5mm。本技术的有益效果是:结构简单,使用方便,上吻合剪和下吻合剪与上环切刃和 ...
