摘要：
A method for effecting a tissue-compressing surgery at a user-selected compression force provides an electrical switch having switching states changed solely by mechanical movements. The switch is mechanically coupled with an adjustable biasing device retaining the switch in one state until a force greater than the bias device is imparted to the switch. The switch is in line with a tissue-compressing device to place a proportional amount of compression force on the switch as imparted upon the tissue. The biasing device is set to a desired state-changing tissue compression force so that the switch changes its state when the force on the switch is at least the desired force. Tissue compresses until a force imparted on the switch at least equals the desired state-changing tissue compression force and, at such time, the switching state changes and, thereafter, a surgical procedure is carried out on the compressed tissue.
