Description

Accurate positioner of ultrasonic wave rubble

Technical Field

The invention relates to a medical instrument, in particular to an ultrasonic lithotripsy accurate positioning device.

Background

Traditional external ultrasonic lithotripsy device fixes a position through B ultrasonic when using, then pastes supersonic generator tight health, then makes internal calculus go on the breakage through cavitation effect and mechanical effect that produces when contacting internal calculus through the ultrasonic shock wave that supersonic generator produced, but because the ultrasonic impact of the ultrasonic wave of adoption to the range of covering indiscriminate, inevitable can cause the injury to some tissues of human body, so the phenomenon that many patients can appear hematuria and health uncomfortable after carrying out external ultrasonic lithotripsy.

On the other hand, in the case of ultrasonic lithotripsy, since most of human tissues are water, and water accounts for 75% of the brain, 75% of the heart, 86% of the lung, 86% of the liver, 83% of the kidney, 75% of the muscle, 94% of the blood, 80% of the cartilage, and 50% of the connective tissue, there is almost no attenuation when the ultrasonic waves enter the human body from the water when the human body is immersed in the water in the case of ultrasonic lithotripsy, and thus the attenuation when the ultrasonic waves propagate is reduced when the human body is immersed in the water in the case of ultrasonic lithotripsy.

The mechanism of the impulse waveform is: non-linear acoustics.

Sinusoidal finite amplitude sound wave propagation: media density ↓ → media compressibility ↓ → propagation velocity ↓. Different pressures on the waveform and different sound velocities result in a change in the waveform.

Calculus is mainly located in kidney, and detection and location of calculus in kidney are realized; 1. abdominal plain (k.u.b): more than 95 percent of urinary calculi are positive calculi, so for patients suspected of having urinary calculi, the K.U.B examination should be the first choice, and the method has the advantages that the position, the size, the position, the number and the density of the calculi can be comprehensively known, and most importantly, the middle-segment and lower-segment ureteral calculi can not be missed for diagnosis.

3. Urography: the method comprises intravenous urography (I.V.P) and retrograde urography, and the intravenous urography is commonly used, can accurately position calculi and is greatly helpful for judging whether diverticulum calculi or renal calyx stenosis exists; the retrograde urography is applied under the conditions that the kidney and the urinary function are poor and the kidney is not developed, and aims to clearly know whether the urinary tract is obstructed or not after the intravenous urography fails.

4. Examination of a kidney diagram: for allergic calculus patients, renal function should be known by renal picture examination.

Ultrasonic focusing: the ultrasonic focusing has good tissue penetrability and energy storage, the host generates a high-frequency electric signal, the high-frequency electric signal is converted into focused ultrasonic waves through the transducer, the ultrasonic waves are conducted into pathological change tissues by utilizing a circulating water system, a sound-transmitting membrane and a contact coupling agent, the ultrasonic waves can generate a heat effect, a mechanical effect, a cavitation effect and a biochemical effect caused by the heat effect, the mechanical effect and the mechanical effect when passing through stones, and the stones can be crushed to a certain size through the cavitation effect and the mechanical effect generated when passing through the stones and then are discharged out of the body through a urinary tract.
