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.

Abstract: A force limiting apparatus for a surgical instrument to prevent too much force being applied to the jaws of the instrument. The instrument has a body with a drive shaft coupled to a pair of jaws, a bearing tube secured to the drive shaft, and a pair of tracks carrying a pivot pin that is biased into one end of the track. A lever is coupled to the pivot pin and abuts the bearing tube to move the bearing tube and close the jaws when squeezed by a user. If the lever is over actuated, the pivot pin will slide along the track against the bias of the spring assembly with the lever pivoting about the bearing tube rather than the pivot pin. As a result, the additional movement of lever does not result in any addition force being transmitted to the drive shaft via the bearing tube.

Abstract: A system for a medical device that can operate multiple actuated implements with sophisticated and individual motion profiles using a single user actuator. The system has a handle having a pair of slots for each implement and an actuator positioned in the handle for movement between a first position and a second position that has a groove for each implement. Each implement is coupled to the handle a barrel that is captured in the pair of slots and driven by the groove of the actuator. The shape of the pair of slots and the corresponding groove combine to provide a motion profile for the implement that is independent from any other implement having its own pair of slots and groove. Multiple implements may thus be driven simultaneously and can have complex and coordinated movement based on user operation of the single actuator.
