Forceps for biopsy

PURPOSE: To achieve simplifying the manufacturing and assembling lines of forceps, by unifying the pivotally-moving members and arm's pivot structure into one unit for forceps whose two forceps spoons pivoted facing with each other are opened and closed via the pivotally-moving members and arms by operating the cables. CONSTITUTION: This forceps for biopsy has two forceps spoons 3 pivoted in facing the forceps head 1/axis 2 with each other. For these spoons 3, the rear arms 4 are pivoted to the one end of shackle-type pivotally-moving members 5. This pair of pivotally-moving members 5 are pivoted onto the top end of the cable housing 6. Operating the cables 8 housed into the elastic mantle 7 opens/closes this pair of forceps spoons 3. In this case, unifying both the free- coupling bearings 19 and the pivotally-moving members 5 into one unit in the arms' 4 axial hole and coupling the bearings 21 made at the both sides of the cable housing 6, make it easier to assemble both the arms 4 and the pivotally- moving members 5.
