Connecting rod typed vertebral body expanding and fixing brace and operation tool thereof characterized by making two supporting plates expand or contract. Therefore, when in the contraction state, the implant surgery can be carried out conveniently, and after implantation, the expending angle of the supporting plates can be adjusted
The present invention relates to a connecting rod typed vertebral sbody expanding and fixing brace mainly comprising a brace head, a screw rod, a pushing block, two supporting plates, and two supporting arms. Wherein the brace head is penetratedly equipped with a through hole the screw rod penetrates the through hole of the brace head and comprises a head end and a screw thread section the pushing block is penetratedly equipped with a screw hole, and the screw thread section of the screw rod can penetrate and be screwed into the screw hole two supporting plates respectively use one end thereof to hingedly connect to the corresponding side of the brace head each supporting arm comprises a first end and a second end the first ends of two supporting arms are respectively connected to the pushing block and the second ends of two supporting arms are respectively connected to two supporting plates. By rotating the screw rod, the pushing block can move in the screw thread section so as to drive two supporting arms to make two supporting plates expand or contract. When in the contraction state, the implant surgery can be carried out conveniently and after implantation, the expending angle of the supporting plates can be adjusted. Therefore, the effect of the spine correction can be achieved.本發明係有關於一種連桿式擴張椎體固定支架,主要包括支架頭、螺桿、推塊、二撐板及二撐臂;其中,支架頭貫通設置有通孔;螺桿穿經支架頭之通孔,且螺桿包括頭端及螺紋段;推塊貫通設置有螺孔,且螺桿之螺紋段可穿經並螺合於螺孔;二撐板之一端分別鉸接至支架頭之相對應二側;每一撐臂包括第一端及第二端,且二撐臂之第一端分別連接至推塊,二撐臂之第二端分別連接至二撐板。藉由轉動螺桿而使推塊移行於螺紋段,進而帶動二撐臂使二撐板撐張或縮合;於縮合狀態時可方便進行手術植入;當植入後再調整撐板撐張的角度,以達脊椎矯正之功效。1‧‧‧連桿式擴張椎體固定支架2‧‧‧支架頭21‧‧‧通孔22‧‧‧灌漿孔23‧‧‧套環3‧‧‧螺桿31‧‧‧頭端32‧‧‧螺紋段4‧‧‧推塊41‧‧‧螺孔42‧‧‧插孔5‧‧‧撐板50‧‧‧加強肋51‧‧‧容槽52‧‧‧貫穿孔53‧‧‧鋸齒表面6‧‧‧撐臂61‧‧‧第一端62‧‧‧第二端611,621‧‧‧凸柱7‧‧‧灌漿袋71‧‧‧開口
