Abstract: The invention relates to a pair of surgical pliers for the cutting through of wires (14), screws or the like comprising a cutter gripping lever (1) having a cutting edge (15) at its front end and a handle (13) at its rear end, and a cutting lever (2) pivotally connected to the cutter gripping lever by means of a cutting lever hinge (3) with the cutting lever having a second cutting edge (15') disposed opposite to the first cutting edge (15). A gripping lever (4) is also pivotally connected to the cutter gripping lever (1). A transmission is arranged between the gripping lever (4) and the cutting lever (2). The input drive member (6) of the transmission braced against the cutter gripping lever (1) is loaded by the gripping lever whereas the output drive member (11) of the transmission acts on the cutting lever (2) at the side remote from the cutting edge (15) of the cutting lever hinge (3) which connects the cutting lever (2) to the cutter gripping lever (1).

Abstract: A joint support structure comprising means forming a housing defining a chamber embodies an axially movable wall portion constituting a clamping device which forms one wall portion of the chamber. This chamber contains radially movable means and means responsive to movement of the axially movable wall portion to induce or accommodate a radial shift of said radially movable means. Means projecting outwardly of the housing includes a rod axially movable in response to movements of said radially movable means to clamp a related joint element to or release the related joint element from a defined seat.Various arrangements are provided to constitute the means responsive to movement of the axially movable wall portion, each of which dictates that essentially the total of the applied forces are translated into a direct radial movement of the rod or rods associated with the joint support structure.
