摘要： An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes an activation member that is operable to move in a first direction to select a mode of operation. The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.

摘要： A surgical instrument includes an end effector and a handle assembly. The end effector is configured to operate at a first energy level and at a second energy level. The end effector is further configured to transition between an open position and a closed position. The end effector is configured to grasp tissue in the closed position. The handle assembly includes a body, a trigger, and an activation element. The trigger is configured to pivot in a first direction relative to the body to actuate the end effector from the open position to the closed position. The activation element is configured to activate the end effector at either the first energy level or the second energy level. The trigger is configured to either activate the activation element or determine whether the end effector operates at the first energy level or the second energy level.

摘要： Methods and apparatus for end effector control and calibration are described. The method may include detecting a signal in response to movement of a first tube relative to a second tube, the first tube driving movement of a clamp arm of the end effector. The method may further include determining a clamp arm position of the end effector relative to a ultrasonic blade of the end effector based on the signal. The method may also include adjusting a power output to the ultrasonic blade of the end effector based on the clamp arm position.

摘要： Methods and devices are provided having a locking mechanism configured to selectively prevent actuation of the surgical device, e.g., opening and closing of jaws at a distal end of the device, moving a cutting element of the device, etc. In an exemplary embodiment, a device is provided having a closure lever actuator that can move between an open position and an actuated position, thereby opening and closing, respectively, jaws at the distal end of the device. In addition, the device can include a knife trigger that is configured to move a cutting element through the jaws. The device can further include a knife lockout feature that can prevent actuation of the knife trigger until the closure lever is in the actuated position.

摘要： Methods and devices are provided for retracting a cutting assembly in the event of a failure on a motorized electrosurgical device. For example, a surgical device is provided with a handle that has an elongate shaft assembly with first and second jaws for engaging tissue. A cutting assembly is included in the surgical device that cuts tissue engaged between the first and second jaws. The surgical device also includes a drive shaft that extends from the handle through the elongate shaft and moves the cutting assembly relative to the first and second jaws, and a motorized gear assembly that causes movement of the drive shaft. In an exemplary embodiment, the elongate shaft assembly is detachable from the handle such that, when detached, the drive shaft can be manually retracted relative to the elongate shaft to retract the cutting assembly from to the first and second jaws.

摘要： A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section is operable to flex to thereby deflect the end effector from a longitudinal axis defined by the shaft. The rigidizing member is operable to selectively rigidize the articulation section and thereby prevent deflection of the end effector by preventing flexibility of the articulation section. Such rigidization includes removing any “play” or other small movement that might otherwise be provided by the articulation section due to manufacturing tolerances and/or looseness between parts.
