新型智能微创拔牙器的设计 THE DESIGN OF THE INTELLIGENT MINIMALLY INVASIVE TOOTH EXTRACTION DEVICE 摘要 鉴于现今的拔牙技术落后，导致病人在拔牙时会产生很大的伤害，对病人的心理上也造成了很大的伤害，所以我在参照国内外各个拔牙器械的设计后，对一种微创智能拔牙器进行了设计。设计理念就是利用各种增利的机构来达到拔牙的目的，本次设计用到的增利机构有滑动螺旋传动、斜楔机构、杠杆机构，由一种动力来驱动，由各个增力机构来传动，滑动螺旋传动采用的是螺杆转动螺母移动，斜楔机构就是很简单改变转动的方向也能达到增力的作用，最后通过杠杆拔起拔牙螺丝，达到拔牙的目的，这种拔牙的方式更加的先进，符合当前的科学技术发展进程，下面就根据上面阐述的这个思路来对毕设题目进行设计和计算。 关键词拔牙；微创；机械 Abstract I
