    摘要： A trocar and trocar obturator assembly having an obturator and a locking mechanism responsive to proximal, axial movement of the trocar obturator is disclosed. The trocar obturator has an elongated obturator shaft having a proximal end and a distal end with a piercing tip mounted thereto. The proximal end of the trocar obturator shaft is slidably mounted in a handle such that the obturator shaft is moveable axially. A protective safety shield having a distal end and a proximal end with a flange member mounted to the proximal end is slidably mounted on the trocar obturator. The safety shield is moveable, axially, between an extended distal position and a retracted proximal position. The protective safety shield is disposed concentrically about the obturator. A lockout arm for locking the safety shield in a locked extended position is mounted in the trocar obturator handle. An actuating collar member is mounted to the proximal end of the obturator shaft in the obturator handle and is moveable with the obturator shaft. The obturator collar disengages the locking arm when moved proximally and engages the locking arm when trocar is armed. The trocar obturator assembly may be concentrically mounted in a trocar cannula having a passageway for receiving the trocar obturator and safety shield. The locking mechanism is actuated by proximal, axial motion of the obturator.

    摘要： An improved articulation mechanism is described in conjunction with a therapeutic ultrasound instrument. Ultrasonic vibrations, when transmitted to organic tissue at suitable energy levels and using a suitable end-effector, may be used for the safe and effective treatment of many medical conditions. The mechanism includes an actuating arm with a collar operatively connected to the actuating arm. The collar converts rotation of the actuating arm into a plurality of actuations of the surgical instrument. In one embodiment the collar includes two ranges of motion, where the first range is used to articulate the surgical instrument, and the second range is used to actuate the surgical instrument. Such instruments are particularly suited for use in minimally invasive procedures, such as endoscopic or laparoscopic procedures.

    摘要： The present invention describes ultrasonic surgical instruments that include a mechanism for clamping tissue against an ultrasonic blade, including an arrangement for detachably mounting a clamp arm to the instrument. The ultrasonic surgical instrument comprises a waveguide adapted to be acoustically coupled to an ultrasonic transducer, and to transmit ultrasonic energy to an end-effector located at the distal end of the waveguide. A support tube extends from a handle assembly and surrounds at least a portion of the waveguide, terminating proximal to the end-effector. A clamp arm is detachably mounted to the distal end of the support tube. An actuation element is operatively coupled to the clamp arm. The ultrasonic surgical instrument may also include a clamp arm release. The actuation element comprises a first range of motion and a second range of motion, whereby moving the clamp arm release from a second position to a first position increases allowable motion of the actuation element from the second range of motion to the first range of motion, thereby facilitating release of the clamp arm from the support tube. The ultrasonic surgical instrument may include the capability for the clamp arm, actuation element, support tube and waveguide to rotate within the handle assembly.
