PROBLEM TO BE SOLVED: To provide an instrument allowing producing a battery, and delivering the battery to an affected part to take out, in view of the fact that a small multipolar battery causes systematic extinction and breakdown of the cancer tissue in a cancer treatment.SOLUTION: A metal etching technique is used for fine processing of an electrode, and an injection molding technique diverting super-alloy is used in processing of a battery housing. A battery is buried in the cancer tissue to be wetted in body fluid so that the multipolar battery may initiate an electric current between a positive electrode and a negative electrode, and the cancer tissue causes tissue systematic breakdown and extinction. In a medical treatment service industry, surgical invasion in cancer patient medical treatment is suppressed and the cancer tissue is made small.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】小さな多極性の電池でがん治療におけるがん組織の組織的な死滅破壊を起こす。その電池の製造と電池を患部まで到達させて取出しを行える器具の提供にある。【解決手段】電極の微細加工においては金属のエッチング技術をつかい、電池筐体の加工においては超合金を流用した射出成形技術をつかう。電池をがん組織に埋設することで体液に湿潤して多極性の電池は正極と負極の間で電流が惹起する、がん組織は細胞組織的破壊死滅を起こす。医療サービス産業においてがん患者治療における外科的侵襲を抑えて、がん組織を小さくすることができる。【選択図】図4
