Surgical instrument tool, includes the 1st part and the surgical instrument tool itself which are enclosed by the film, the cavity in the 2nd part and surgical instrument tool itself and, it includes. The cavity is formed, in order to receive the 1st part. The 2nd part, the portable possible closed component and, includes the 1st field and with of 1st position and the 2nd position which include the opening which is communicated with the cavity. When as for the closed component, when being 1st position, the 2nd field and sealing there is possibly an engagement state, being 2nd position, at least part is not the 2nd field and engagement state. The 1st part or as for the electric contact point of one or more on the 2nd part, when the closed component moves to 1st position from 2nd position, penetrating completely the film, in order for it to be possible to form joint with the 1st part and the 2nd part, it is constituted.外科用器具は、膜によって封入される第1の部分と、外科用器具本体を含む、第2の部分と、外科用器具本体の中の空洞と、を含む。空洞は、第1の部分を受容するように構成される。第2の部分は、空洞と連通する開口部を含む第1の領域と、第1の位置と第2の位置との間で移動可能な閉鎖部材と、を含む。閉鎖部材は、第1の位置にあるときに第2の領域と密封可能に係合状態にあり、第2の位置にあるときに、少なくとも一部が第2の領域と係合状態でない。第1の部分又は第2の部分上の1つ以上の電気接点は、閉鎖部材が第2の位置から第1の位置へと移動するときに膜を貫通して、第1の部分と第2の部分との間に接続を形成することができるように構成される。
