摘要： In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.

摘要： A surgical generator (102) that may produce a drive signal or signals of particular voltages, currents and frequencies, e.g. 55,500 cycles per second (Hz). The drive signal or signals may be provided to an ultrasonic surgical device (104) and specifically to a transducer. In one embodiment, the generator may be configured to produce a drive signal of a particular voltage, current and/or frequency that can be stepped with high resolution, accuracy and repeatability. Additionally, the surgical generator may generate a drive signal or signals with output power sufficient to perform bipolar electrosurgery using radio frequency (RF) energy. The drive signal may be provided, for example, to electrodes of the electrosurgical device (106). Accordingly, the generator may be configured for therapeutic purposes by applying electrical signals to an ultrasonic transducer or electrical energy to the tissue sufficient for treating the tissue (e.g., cutting, coagulation, cauterization, tissue welding).

摘要： An ultrasonic surgical system utilizes a digital control system to generate ultrasonic drive current for transducers that are located in a hand piece and are attached to a surgical scalpel or blade in the hand piece so as to vibrate the blade in response to the current. The digital control includes a digital signal processor (DSP) or microprocessor; a direct digital synthesis (DDS) device; a phase detection logic scheme, a control algorithm for seeking and maintaining resonance frequency; and design scheme that allows to regulate current, voltage, and power delivered to an ultrasonic thereby a device. Such system allows the power versus load output curve to be tailored to a specific hand piece, which improves efficiency and reduces heat. Further, the components of the digital system are much less sensitive to temperature variations, thereby allowing it to operate with narrow as needed frequency range around the desired resonance in order to avoid excitation of other resonances. Also, the digital system provides increased flexibility in locating the resonance frequency of the blade and running diagnostic tests. The start of a user initiated diagnostic test that requires movement of the blade is caused by operating two of the system switches, which guards against accidental operation of the blade which could be harmful if in contact with tissue and also generate false diagnostic results. In addition, the system has interlock with an Electrosurgical unit so that it is not effected by the electromagnetic interference generated by that unit.

摘要： A method for detecting transverse mode vibrations in an ultrasonic hand piece/blade is achieved by monitoring the power delivered to the hand piece/blade to determine whether it increases as expected when power levels applied to the hand piece/blade are changed. While the blade is being held in midair, the power delivered to the hand piece/blade and/or the impedance of the hand piece/blade is measured at a first power level. Using the value obtained at the first power level, the expected power at a second power level is calculated and used to set a pass/fail threshold level for an actual measured power. Alternatively, the threshold is set for the impedance is set. Next, the actual power delivered to the hand piece/blade and/or the impedance of the hand piece/blade is measured at a level 5 power setting. A determination is made whether the hand piece/blade exhibits transverse mode behavior based on whether the actual measured power exceeds the established pass/fail threshold level. If this is the case, operation of the generator is inhibited, a “Transverse Mode Vibrations Present in Hand Piece/Blade” error code is stored in the generator, and a “Bad Hand Piece” message is displayed on a liquid crystal display on the generator. In addition, a method for detecting transverse mode vibration in an ultrasonic hand piece/blade is achieved by monitoring power delivered to the hand piece/blade to determine if the an extraordinary power increase occurs as the drive frequency is shifted downward and/or upward from a primary intended resonance operating frequency.

摘要： The ability of an ultrasonic system to sweep and lock onto a resonance frequency of a blade subjected to a heavy load at startup is improved by applying a high drive voltage or a high drive current while systematically increasing the level of the applied signal. Increasing the drive signal to the hand piece results in an improved and more pronounced “impedance spectrum.” That is, under load, the increased drive signal causes the maximum phase margin to become higher and the minimum/maximum impedance magnitude to become more pronounced. Increasing the excitation drive signal to the hand piece/blade at startup significantly alleviates the limiting factors associated with ultrasonic generators, which results in an increase of the maximum load capability at startup.
