This invention has, the 1st magnet (110) outside possessing, the tubular component (101), and the 2nd magnet (111) inside possessing, the tubular component (103), the inside tubular component (103) the outer part tubular component (101) the cutting instrument which sliding possibly is arranged (100) regards inside. Power such as gravitation or bounce, the 1st magnet (110) with the 2nd magnet (111) with is formed between. Gravitation or bounce, the inside tubular component (103) with the outer part tubular component (101), or the inside tubular component (103) with forms residual pressure power with the hand pieces which are engaged. Also the method of forming power between the tubular component of the other cutting instrument and inside and outside is disclosed.本発明は、第1の磁石(110)を有する外側管状部材(101)、および第2の磁石(111)を有する内側管状部材(103)を備え、内側管状部材(103)が外側管状部材(101)内に摺動可能に配置される切断器具(100)に関する。引力または反発力など力が、第1の磁石(110)と第2の磁石(111)との間に生成される。引力または反発力は、内側管状部材(103)と外側管状部材(101)、または内側管状部材(103)と係合されるハンドピースとの間に予圧力を生成する。他の切断器具および内側と外側の管状部材の間に力を生成する方法も開示される。
