  • Patent number: 8888767
    Abstract: An improved method and device for safe and efficient medical applications is provided. In a preferred embodiment, based on using the inherent benefits of laser diodes (such as efficient power generation from a reliable and compact solid state device), plasmas and high energy vapors are produced for medical applications with power levels and power densities sufficient to treat medical indications and avoid the creation of extensive damage zones. Transmissions means in different configurations are used to achieve a high power density, which is able to initiate plasma and high-energy vapor at the tip. Once a sparkless plasma and high energy vapor bubbles are formed, it is often found that it will also absorb other wavelengths in addition to the one that initiated it. As a consequence, other wavelengths more efficiently generated by diodes or diode pumped lasers may be added into the beam in order to improve treatment efficiency.

    Abstract: An erythema meter includes a probe, a light source of one or more specific probing and reference wavelengths, and an acoustic detector which determines the level of erythema present in the dental pulp chamber of a tooth. The probing and reference wavelengths are delivered in pulsed or amplitude modulated fashion through the probe, thereby permitting electronic identification and filtering of the received data. The absorption of the light wave raises the temperature of the material in the tooth and causes it to expand, thus creating tiny shockwaves which are picked up with the acoustic detector, revealing information on the location of blood and the quantity of blood inside the tooth. The erythema meter accurately measures the erythema, or inflammation, within the tooth in a qualitative and quantitative manner.

The vortex bubble-removing and cooling system comprises a water-full cushion (17), a metal diaphragm (14) installed inside the chamber body (27) of the water cushion (17) and a coil (13) which is installed at the backside of the metal diaphragm (14). There is at least one first water nozzle (22) on the side wall of the chamber body (27) and a water suction tube (23) at the center of the chamber body (27). The first water nozzle (22) and the water suction tube (23) form a vortex-generating device. The vortex generated inside the chamber body will scour the surface of the metal diaphragm continuously so as to cool the heat and remove the air bubble. This will make the metal diaphragm be in good working condition and greatly increase the working life of the metal diaphragm and the coil.

  • Patent number: 6966906
    Abstract: A mechanism and method for steering a surgical instrument inserted into an endoscope such as a ureteroscope, nephroscope, or cystoscope, and/or for steering the endoscope, utilizes a shape memory structure secured to the surgical instrument or to the endoscope, the shape memory structure having a transformation temperature slightly greater than that of the human body so that bending of the shape memory structure, and therefore of the surgical instrument or endoscope, may be carried out by raising a temperature of irrigation fluid in the working channel. The steering mechanism may be used as a supplement to a tensioned-wire steering mechanism, reducing stress on the endoscope shaft and extending the service life and repair interval of the endoscope. In addition, when the surgical instrument is a glass optical fiber, the steering mechanism may be used to ensure that a tip of the optical fiber is within the field-of-view of fiber optics incorporated into the endoscope.

    Abstract: A system and method for a lithotripter is provided. The system can include a shockwave generator and an ultrasonic transmitting/receiving unit, which are in communication with an evaluating unit. The transmitting/receiving unit can include an ultrasonic transducer that emits ultrasonic pulses and receives ultrasonic waves reflected from a target area of the shockwave generator. The evaluating unit can determine a correlation coefficient of the time correlation between the ultrasonic waves and the ultrasonic pulses and provide a signal related to the coefficient. The method can include emitting ultrasonic pulses from the transducer into a body, receiving the ultrasonic waves reflected from a target object in the body, evaluating the received ultrasonic waves with the evaluating unit to determine the correlation coefficient, and providing a signal related to the correlation coefficient.
