摘要： A surgical instrument. The surgical instrument may comprise a transducer and an end effector. The transducer may be configured to provide vibrations along a longitudinal axis at a predetermined frequency and may comprise a piezoelectric stack positioned along the longitudinal axis. The transducer also may comprise a first metallic end mass positioned along the longitudinal axis adjacent a first end of the piezoelectric stack and a second metallic end mass positioned along the longitudinal axis adjacent a second end of the piezoelectric stack. The length of the transducer may be greater than or equal to of one wavelength and less than ½ of one wavelength. The end effector may be coupled to the transducer and may extend along the longitudinal axis. The length of the transducer and the end effector may be a multiple of ½ of one wavelength.

摘要： This invention is a method of manufacturing high-power sandwich type ultrasonic transducers (82), and more particularly, a new method of tuning high-power sandwich type ultrasonic transducers (86) without the need for a trimming process. A method in accordance with the present invention includes the steps of assembling a sandwich type ultrasonic transducer (82), measurin g the resonant frequency of the ultrasonic transducer (82), and selecting from a plurality of tuning elements (50), whereby a dimension or material property of a selected tuning element alters the measured resonant frequency of the ultrasonic transducer (82) to a desired resonant frequency after the tuning element (50) is attached to the ultrasonic transducer (82).

摘要： An ultrasonic surgical system utilizes a digital control system to generate ultrasonic drive current for transducers (36) that are located in a hand piece (30) and are attached to a surgical scalpel or blade (32) 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 (60); 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： Procedimiento para distinguir entre mangos defectuosos y fallos de cuchillas en un sistema quirúrgico ultrasónico, que comprende las etapas de: aplicar una señal de excitación sobre un mango/cuchilla ultrasónico a una frecuencia de excitación predeterminada; monitorizar y almacenar una velocidad de cambio de una frecuencia de resonancia y una velocidad de cambio de una impedancia de resonancia del mango/cuchilla a medida que la frecuencia de excitación cambia en la memoria del generador; efectuar una prueba de autodiagnóstico en un generador ultrasónico situado en el sistema quirúrgico ultrasónico; monitorizar el generador ultrasónico del sistema quirúrgico ultrasónico para determinar si existe sincronización; si no existe sincronización, extraer de la memoria del generador la velocidad de cambio de la frecuencia de resonancia y la velocidad de cambio de la impedancia de resonancia; comparar la velocidad de cambio de la frecuencia de resonancia y la velocidad de cambio de la impedancia de resonancia para obtener la velocidad de cambio más elevada, la cual se almacena en la memoria del generador; y si las velocidades de cambio son superiores a las velocidades de cambio normales debidas a los cambios de temperaturas asociados a las cuchillas más largas, mostrar un mensaje en un indicador visual de cristal líquido del generador.

摘要： A control system for use with an ultrasonic surgical instrument includes a generator supplying electrical energy to an ultrasonic surgical instrument, the electrical energy supplied by the generator being controlled such that power applied by the instrument is maintained constant once a predetermined pressure threshold is met. The control system operates by assigning a nominal power at which the ultrasonic instrument is to operate and adjusting the current and voltage applied to the ultrasonic surgical instrument so as to maintain the power applied by the ultrasonic surgical instrument at approximately the nominal power.

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. Next, the actual power delivered to the hand piece/blade and/or the impedance of the hand piece/blade is measured at a higher 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： An ultrasonic surgical hand piece is caused to be driven with an output displacement that is correlated with the phase margin, which is the differen ce of the resonant frequency and the anti-resonant frequency of the hand piece. A frequency sweep is conducted to find the resonant frequency and the anti-resonant frequency for the hand piece. The resonant frequency is measured at a point during the frequency sweep where the impedance of the hand piece is at its minimum. The anti-resonant frequen cy is measured at a point during the frequency sweep where the impedance of the ha nd piece is at its maximum. Using a target or specific output displacement, a drive current is calculated based on the phase margin which is the difference between the resonant frequency and the anti-resonant frequency. The hand piece is caused to be driven with the output displacement, by accordingly controlling the current output from a generator console for driving the hand piece.
