Abstract: A bipolar surgical instrument having a front region (3) with at least four coagulation elements (6, 7, 8, 9) entered in the slots at the at least four corners of a rectangle or at least four quarters of a circle of the insulation body (22) for coagulating and one cutting element at the centre of insulating body for cutting the tissue and/or vessel in the body, thereby having an at least five electrode arrangement for handling and treating the tissue and/or vessel. The cutting element (10) can be at least one blade or at least one needle and it can be fixed or moved longitudinally in an advanced position or retracted position.

Abstract: A vessel sealer having a uniform pressure mechanism, detachable blade/cutter and detachable jaw assembly is disclosed. A bipolar surgical instrument, includes a jaw assembly having jaws connected to an outer tube, wherein the blade is connected to the blade pushing tube through a blade connector; a spring cap operatively engages said blade tube assembly wherein on disengagement of the said jaw assembly from an outer tube and said spring cap from said blade pushing tube are adapted to be detached from each other; a handle assembly, operatively coupled to said jaw assembly comprising a uniform pressure mechanism which contains primary spring, a secondary spring, wherein said uniform pressure mechanism enables closure of the jaws to ensure and exert a uniform pressure on the tissue and/or vessel.
