Description

电动吻合器 技术领域
本发明涉及医疗器械技术领域，特别是涉及一种电动吻合器。
背景技术
医用吻合器是对消化道生理组织施行外科手术时经常使用的一种医疗器械，在普外科手术治疗中，吻合器常被用于完成组织的切割、缝合。吻合器在对生理组织实施“闭合、吻合、切割”的操作过程为手动操作或电动操作。
手动操作是以纯机械方式实现钉砧头和钉仓之间的闭合动作和对吻合组织的击发动作，击发过程需要巨大的击发力才能完成吻合口的切割闭合，对使用者的要求极高，一旦技巧和力度掌握的不佳很容易造成器械击发不动或只能击发一半，而击发力不足会影响组织闭合效果，导致切割闭合不完全，最终导致手术失败，风险极高。而电动吻合器只要电量足够，则不存在发力不够的风险。
但是手动吻合器，医生手术时完全依据经验判断合理的组织压榨程度(绿区范围内从1.5-2.5mm)不能针对不同病人的组织特征提供相应精确的组织压榨厚度。依据经验判定组织压榨厚度的误差造成不同病人术后效果离散型较大，不仅影响手术的效率，还会出现成钉不一致、二次成钉等现象，从而出现组织泄露，组织坏死等术后症状。
发明内容
基于此，有必要提供一种能有效确保最佳的组织压榨和稳定的成钉效果的电动吻合器。
一种电动吻合器，包括：手柄，包括手柄本体、驱动电机和控制驱动电机工作的控制单元；工作头，包括钉砧头、钉仓、闭合机构、击发机构、安装闭合机构和击发机构的壳体，还包括向控制单元发送所述闭合机构的闭合行程信息的闭合限位开关、用以向所述控制单元发送闭合时作用于被压榨组织的压力值的压力传感器；其中，当所述闭合限位开关被触发、且所述压力传感器发送的压力值符合预定标准时，所述控制单元发出控制所述驱动电机
