摘要： Disclosed is an ultrasonic medical device that may include a surgical tool having a proximal end, an end effector, and a waveguide between them, a first transducer in mechanical communication with a first face of the surgical tool, and a second transducer in mechanical communication with an opposing face of the surgical tool, opposite the first transducer. The first transducer and the second transducer are configured to operate in a D31 mode with respect to the waveguide of the surgical tool. Another aspect comprises a method of fabricating the ultrasonic medical device, in which the surgical tool is machined from a portion of a flat metal stock so that the surgical tool has a longitudinal axis oriented at an angle with respect to a grain direction of the flat metal stock thereby optimizing an operational characteristic of the surgical tool.

摘要： A surgical system, comprising a surgical tool including a shaft and an end effector formed at a distal end thereof, the end effector having a clamping element and an ultrasonic blade, the clamping element being movable relative to the ultrasonic blade to clamp and treat tissue disposed between the clamping element and the ultrasonic blade. The system further comprising a closure mechanism configured to move the clamping element towards the ultrasonic blade from an open configuration to a closed configuration at a predetermined clamping velocity and a control system. The control system configured to maintain a first clamping velocity greater than a minimum clamping velocity until a predetermined clamping force threshold is achieved, determine a closure parameter including an amount of time and displacement required to reach the force threshold, determine a tissue characteristic based on the closure parameter, and deliver energy to the ultrasonic blade to treat tissue according to a feathering treatment protocol based on the tissue characteristic.

摘要： Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

摘要： Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.

摘要： A surgical instrument includes a transducer assembly (2500) with a housing (2502) having a conduit section (2510) and a base portion (2520). A fluid passageway (2515) is defined through the conduit and base portion (2520), an ultrasonic transducer (2504) including a plurality of piezoelectric elements (2508A-D) and a plurality of electrodes (2509A-D) are arranged in a stack (2504) configuration, where an electrode is located between each pair of piezoelectric elements. A first borehole (2527) is defined through the ultrasonic transducer (2504) and an end mass (2506) having a second borehole (2527) defined therethrough. A surface (2330) of the end mass (2506) is positioned adjacent a first end of the ultrasonic transducer (2504), the end mass (2506) is configured to engage with the housing (2502), and the conduit section (2510) of the housing (2502) is configured to pass through the second borehole (2527) of the end mass (2506). The end mass (2506) is configured to compress the ultrasonic transducer (2504) against a surface (2330) of the housing (2502) when the end mass (2506) is engaged with the housing (2502).

摘要： A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.
