RESUMO
Objective To introduce the design of a multi-functional medical forceps which containing the functions of cutting , easily conversion between tooth forceps and toothless forceps .Methods To design a multi-functional medical forceps ,including forceps arm ,blade groove,blade retaining plate,first magnet,forceps rotating parts,fixed plate groove,second magnets,forceps groove,slider,metal sleeve and two protection slot,which containing the functions of cutting ,easily conversion between tooth forceps and toothless forceps ,and so on.Results The multifunctional medical forceps can prevent unstable tissue clamp and achieve the conversion between tooth forceps and toothless forceps . Moreover,the cutting function can be achieved when the tissue is to be cut .Conclusion The multi-functional medical forceps can theoreti-cally solve the problems caused by the traditional forceps in the exchange of instruments , and it can save the time of changing medical ma-chinery so as to achieving the purpose of reducing the operation time and improving the operation efficiency .
