A kind of inner core with what bipolar ablation device,Comprising the insulation outer tube of Hou extension before one,Interval be fixed on insulation one of outer tube front end anode electrode head and a negative electricity cartridge,It is spaced one of the fixed what insulation outer tube Hou end cathode metal connection ring and a negative metal connection ring,And wear respectively installation the what insulation outer tube in one of anode electrode silk and a negative electricity polar filament,The anode electrode silk is electrically connected between the what cathode metal connection ring and the anode electrode head,The negative electricity polar filament is between electrical connection what negative metal connection ring and the negative electricity cartridge. Through by the design of the anode electrode head and the negative electricity cartridge spacing parallel arranging setting what insulation outer tube front end, the front end size of the inner core can be substantially reduced, and the cavity space of inner core relatively narrower in human body is enable to operate.一種用於雙極消融器的內芯，包含一前後延伸之絕緣外管、間隔固定在絕緣外管前端之一正極電極頭和一負極電極頭、間隔固定於該絕緣外管後端部之一正極金屬連接環和一負極金屬連接環，及分別穿設安裝於該絕緣外管內之一正極電極絲和一負極電極絲，該正極電極絲是電連接於該正極金屬連接環與該正極電極頭間，該負極電極絲是電連接於該負極金屬連接環與該負極電極頭間。透過將該正極電極頭與該負極電極頭間隔並列設置於該絕緣外管前端的設計，可大幅縮小該內芯的前端尺寸，而使該內芯能夠在人體內較狹窄之腔室空間操作。
