Abstract
A scissor style vessel sealer having a first shaft interconnected to a first jaw by a pivot plate that pivotally couples the first shaft to the first jaw by the pivot and also by a spring that is secured at one end to the first shaft and an opposing end to the pivot plate at a location offset from the pivot and a second shaft connected to a second jaw and pivotally coupled to the first jaw by the pivot. The first shaft and the second shaft are then pivotable from a jaws open position to a jaw closed position. Any further application of force results in the first shaft pivoting relative to the first jaw so that the additional force is not transmitted to the jaws. The first shaft pivoting relative to the first jaw may actuate a button associated with the second shaft.
