    摘要： 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.

    摘要： A surgical instrument includes a handle movable between first and second positions for transitioning an end effector assembly between states and to a third position for returning the handle. A latch arm coupled to the handle includes one or more engagement members. A latch block defines a guide track having a latching path configured to guide the engagement member(s) therealong, an engagement portion configured to engage the engagement member(s) to latch the handle in the second position, and a return path configured to guide the engagement member(s) therealong. A first step interdisposed between the latching path and engagement portion guides the engagement member(s) into engagement with the engagement portion and inhibits the engagement member(s) from returning along the latching path. A second step interdisposed between the engagement portion and the return path guides the engagement member(s) along the return path and inhibits the engagement member(s) from re-engaging the engagement portion.
