摘要:
Ultrasonic surgical device is provided. The device includes a shell which holds an energy converter and an amplitude-change pole. The energy converter may include piezoceramic stack that converts electrical signals into mechanical ultrasonic movement in the longitudinal direction of the device. The amplitude-change pole is a mechanical amplifier that uses mass differentials to amplify the ultrasonic motion. A cutting instrument interfaces with the amplitude-change pole. A drive motor causes on oscillation mechanism, which may be a rocker, to oscillate in a direction tangentially to the longitudinal axis. The oscillating mechanism may then couple to the energy converter, causing the entire cutting structure to move in this oscillation. This causes the cutter to ultrasonically vibrate along the longitudinal axis, while oscillating tangentially to the longitudinal axis.

Ultrasonic surgical device is provided. The device includes a shell which holds an energy converter and an amplitude-change pole. The energy converter may include piezoceramic stack that converts electrical signals into mechanical ultrasonic movement in the longitudinal direction of the device. The amplitude-change pole is a mechanical amplifier that uses mass differentials to amplify the ultrasonic motion. A cutting instrument interfaces with the amplitude-change pole. The system also includes a rotary drive device comprising a drive motor also axially arranged with the cutting instrument. The motor rotates the amplitude-change pole, energy converter, and ultimately the cutting instrument. In some embodiments the rate of rotation is at 40-1000 rpm, at 50-650 rpm and at 60-350 rpm depending on configuration. In some cases the user may be enabled to alter the rotational speed within these ranges

A metal-carbonyl-containing fire extinguishing composition comprises metal carbonyl complexes. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source. A high temperature in combustion of the pyrotechnic agent enables the fire extinguishing composition to decompose or react under heat; produced fire extinguishing substances are sprayed out together with the pyrotechnic agent, thereby achieving a fire extinguishing objective. In the fire extinguishing composition, by selecting preferable components and optimizing contents of the components, an optimum formula of the fire extinguishing composition is determined, thereby greatly improving the efficacy of the fire extinguishing composition. In addition, efficacies of the components in the fire extinguishing composition are fully utilized, which improves an effective utilization rate of the fire extinguishing composition.
