Tissue compression surgical device

An optimal tissue compression surgical device comprises a handle and a surgical end effector connected to the handle. The surgical end effector comprises an electrically controlled tissue-compression device and a mechanical binary-output electrical switch, wherein a force acting on the mechanical binary-output electrical switch is proportional to a compressing force directed upon the compressed tissue. The mechanical binary-output electrical switch has first and second electrical switching states, a biasing device retaining the switch in the first switching state with a bias force until a force imparted upon the switch overcomes the bias force to change the switch to the second switching state, and a switching-state-status output for providing information identifying the current switching state.
