Abstract
A surgical device, comprising a tissue compression device having a pair of opposing compression surfaces, a mechanical binary-output electrical switch having open and closed electrical switching states initiated and changed solely by mechanical movements, and an adjustable biasing device mechanically coupled to the switch and retaining the switch in one of the switching states until a force at least as great as a force imposed by the biasing device is imparted to the switch, wherein the switch is disposed in line with the tissue compression device to cause a proportional amount of force that is placed upon compressed tissue disposed between the opposing compression surfaces to be placed upon the switch, and the biasing device is set to an amount of force that is proportional to an optimal tissue compression force of the compressed tissue when disposed between the opposing compression surfaces.
