摘要:
A surgical instrument comprises an ultrasonic source (7) and an ultrasonic vibration transmitter (8) connected to the source (7), which generates ultrasonic mechanical vibration. The ultrasonic vibration transducer includes a plurality of ring-shaped cutting blade portions (14) provided on an outer periphery of an operational part (9) which contacts organic tissue, and a liquid passage (11) through the transducer. The liquid passage opens at a front end (12) of the operational part and at recesses (13) between the blade portions. The surgical instrument cuts or incises organic tissue by ultrasonic vibration.

An artificial ventilator includes a dome for covering the precordial and the sides of the thoracoabdominal of a patient, a blower to be used for applying negative and positive pressures within the dome, a regulator for adjusting a pressure, and the like. The valve switching device is controlled by a respiration detection system. In the respiration detection system, a pyrolelectric element is used as a respiratory sensor for detecting a temperature change rate caused by an inspired and expired air flow. The temperature change rate signal obtained by the sensor is compared with a threshold value set by a variable resistor, the start timings of expired air and inspired air are detected in accordance with the comparison result, and air inspiration and expiration start timing signals are outputted. Further, the artificial ventilator can be provided with various functions of forced respiration and intermittent deep breathing by means of a timer, synchronization only with air inspiration timings, reduction of frequency of respiration assistance for the intention not to use the ventilator in the near future, backup during apnea, and the like. The artificial ventilator allows a physilogical respiration assistance matching the patient's physiological intention by synchronizing with the patient' s respiration. Thus, an effort and pain in breathing with a conventional mechanical ventilation can be avoided so that the artificial ventilator is suitable for a long term use and useful for a quick recovery of respiration function of an acute respiratory failure patient.

A surgical instrument for cutting and separating biological tissue by employing ultrasonic vibration, particularly for cutting bones, separating the periosteum, and cutting and separating a coherent mass such as a calcium mass. An ultrasonic vibration-transmitting tool (5) which is connected to an ultrasonic vibration source (4) and performs mechanical vibration at the frequency of the ultrasonic waves has a spoon-shaped working portion (7) which is provided with at least one of a blade-shaped portion (25) forming a predetermined angle with respect to the direction of the mechanical vibration at the frequency of the ultrasonic waves and a blade-shaped portion (23, 24) substantially parallel with the direction of the vibration, the spoon-shaped working portion being adapted to be brought into contact with the biological tissue, and a liquid passage (21) passing through the interior of the ultrasonic vibration-transmitting tool, the liquid passage having an opening (22) which opens into the working portion. Further, by making of ceramic the whole part or the surface portion of the working portion (7) which is provided with the blade-shaped portion to be brought into contact with the biological tissue, it is possible to prevent wear deformation of the blade-shaped portion, and also to prevent transmission of electrical shocks to the nervous tissue in the event of a simple electrical fault state.
摘要:
A management node for managing a program update time refers to an update management table in which a plurality of managed nodes are classified into a plurality of groups and the sequence of program updating of the groups is defined. The management node sequentially selects the groups in accordance with the sequence of program updating in such a manner that after program updating processing has been completed in all managed nodes included in the selected group, the next group is selected. The management node refers to the update management table, transmits a program update request to each of the managed nodes included in the selected group, receives an update completion notification from the managed node, and notifies update management information storing means that the update processing has been completed in the managed node.

A surgical operation device comprising an ultrasonic piezoelectric transducer for generating ultrasonic vibrations, an oscillation feedback type oscillator for supplying high-frequency power to the ultrasonic transducer, a vibration transmitter connected to the ultrasonic transducer for transmitting and amplifying mechanical vibrations at an ultrasonic frequency, a suction unit and an irrigator. The ultrasonic transducer includes a bolted Langevin type transducer. The feedback circuit of the oscillation feedback type oscillator includes an oscillation voltage detector, a phase comparator, a low pass filter, a differential amplifier, and a voltage controlled oscillator. Thus, the mechanical resonant frequency can be traced in a wide range of fluctuations of a load on the vibration transmitter during vibration and vibrations can start an appropriate mechanical resonate frequency irrespective of the load status of the vibration transmitter at the start-up.
