Zusammenfassung:An apparatus includes an end effector, a shaft assembly, a closure jaw assembly, and an adjustment assembly. The end effector includes a first jaw and a second jaw capable to actuate between an open configuration and a closed configuration. The jaw closure assembly includes an elongated jaw closure member, a coupling body attached to the elongated jaw closure member, a yoke housing capable to actuate the coupling body and the elongated jaw closure member to thereby close the second jaw, and an engagement spring capable to bias the coupling body and the elongated jaw closure member into operative engagement with the yoke housing. The adjustment assembly is capable to adjust a spring length of the engagement spring to ensure the coupling body and the elongated jaw closure member remain in operative engagement with the yoke housing.
