    Abstract: An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.

    Abstract: An ultrasonic surgical instrument is provided. The ultrasonic surgical instrument includes a housing having an elongated shaft extending therefrom. The shaft has a jaw member disposed at a distal end thereof. The jaw member is movable between an open configuration and a clamping configuration and includes a tissue contacting surface thereon. A cutting blade extends from a distal end of the shaft and operably couples to the housing and adjacent the jaw member to treat tissue. At least one sensor is configured to sense at least one operational parameter of the ultrasonic surgical instrument. At least one controller in operable communication with the at least one sensor is configured to terminate delivery of ultrasonic energy to the cutting blade when the at least one sensor senses the at least one operational parameter.
