5. bipolar scissors according to claim 4, it is characterised in that: the claw beam component and Handleset clamping and energy
360o rotates, and the rod head on cutting head assemblies is movably connected on back handle, thus pushing drawing rod, and controls of scissors
Open and close are closed.
6. bipolar scissors according to claim 4, it is characterised in that: the bipolar trend of the bipolar scissors is: a pole is
Handleset → claw beam component orients casing → pincers pipe → cutting head assemblies support frame → loop electrode piece；Another pole is hand
Handle component → cutting head assemblies rod head → pull rod → active shear blade；Active shear blade and loop electrode when original state
Piece is separated by the insulation of passive shear blade, non-conductive, does not generate current energy；Active shear blade and passive shear blade when work,
Trapping human organizes between loop electrode piece, and tissue is conductive, at this time bipolar formation closed loop, generates current energy, blood coagulation.
