An embodiment of a medical ultrasound system is described, wherein the medical ultrasound system includes a medical ultrasound handpiece having a medical ultrasound transducer assembly and includes an ultrasonically-vibratable medical-treatment instrument which is attachable to a distal end of the transducer assembly. An embodiment of a medical ultrasound system is described, wherein the medical ultrasound system has a handpiece including a medical ultrasound transducer assembly and including a housing or housing component surrounding the transducer assembly. A method for tuning a medical ultrasound handpiece includes machining at least a distal non-threaded portion of an instrument-attachment stud of the transducer assembly to match a measured fundamental frequency to a desired fundamental frequency to within a predetermined limit. A method for making a medical ultrasound transducer assembly determines acceptable gains for gain stages of the transducer assembly.

摘要： An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The assembly includes a clamping mechanism, including a clamp arm cam-mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces. The balanced blade provides a functional asymmetry for improved visibility at the blade tip and a multitude of edges and surfaces, designed to provide a multitude of tissue effects: clamped coagulation, clamped cutting, grasping, back-cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural axial motion of the user's index or middle fingers, whether gripping the surgical instrument right-handed or left handed.

摘要： A surgical device. The surgical device may comprise a transducer, an end effector, a generator and a control circuit. The transducer may be configured to provide vibrations. The end effector may be coupled to the transducer and may extend from the transducer along the longitudinal axis. The generator may provide an electrical signal to the transducer. Also, the control circuit may modify a current amplitude of the electrical signal in response to a change in a vibration frequency of the end effector. Accordingly to various embodiments, the control circuit may detect a first contribution to a vibration frequency of the end effector, the first contribution originating from tissue in contact with the end effector. Also, according to various embodiments, the control circuit may indicate a change in a vibration frequency of the end effector.

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： The present invention provides a system for implementing surgical procedures which includes an ultrasonic surgical hand piece having an end-effector, a console having a digital signal processor (DSP) for controlling the hand piece, an electrical connection connecting the hand piece and the console, and a memory, such as an EEPROM (Electrically Erasable Programmable Read Only Memory), disposed in the electrical connection. The console sends a drive current to drive the hand piece which imparts ultrasonic longitudinal movement to the blade. The console reads the memory and authenticates the hand piece for use with the console if particular or proprietary data are present in the memory. Moreover, to prevent errors in operating the hand piece, the memory can store certain diagnostic information which the console can utilize in determining whether the operation of the hand piece should be handicapped or disabled. Furthermore, the memory can be used to reprogram the console, if needed.
