Title Design of Medical Forcep Elasticity Test Device
Abstract
With social progress and economic and social development, people are fine level of medical devices have become increasingly demanding, the emergence of high-precision sensors to measure the parameters of the instrument of modern medicine good technical support, the use of high-precision sensors and high-performance MCU Modern medical equipment can accurately measure the parameters of the device is designed not only for the medical field is very important, also contributed to the study of the scope of signal processing technology, micro-controller technology, micro-sensor technology has an important role for people's health living progress and the progress of human society, modern technology has made tremendous contributions. Medical forceps as a medical device in the most typical, the most basic, the most common instrument, its elasticity accurate measurement for the medical field is necessary.
This paper discusses the hardware and software design of medical forcep elasticity test device.
Medical forcep elasticity test device including the weighing sensor circuit modules, power modules, signal conditioning circuit amplification module, microcontroller module, LCD display module, complete action on weak pressure sensor detected signal conditioning, analog-digital conversion, calculated pressure values, and display.
Keywords medical forceps sensors microcontroller signal conditioning

1.1 课题研究背景及意义
微控制单元，英文Microcontroller Unit，简称MCU。又称为单片微型计算机，英文Single Chip Microcomputer，简称单片机，是把中央处理器即CPU的频率与规格做适当缩减，并将内存、数模模数转换、UART、计数器、USB等接口，甚至LCD的驱动电路全部整合在单一芯片上，形成芯片级的计算机，实现为不同的环境做出不同组合的控制或操作。
