Ultrasonic radiation force calculus removal device for treating micro renal calculi

Abstract

The invention discloses an ultrasonic radiation force calculus removal device for safely and rapidly treating micro renal calculi. The calculus removal device comprises an arbitrary waveform generator, a radio frequency power amplifier and a phased array electronic focusing ultrasonic transducer, wherein the arbitrary waveform generator is connected to the phased array electronic focusing ultrasonic transducer by virtue of the radio frequency power amplifier. The device is convenient to operate and precise in focusing; by virtue of pulse ultrasonic radiation force which can be adjusted and increased, the micro calculi, which are 0.1-0.6cm in diameter, can be pushed to fall off from a renal sinus area and a ureter stuck part and to be discharged out of a body, so that physical calculus removal is achieved; the device has a broad prospect of clinical popularization and application; and the device is simple in structure and suitable for industrial production.

Description

technical field [0001] The invention relates to a device for removing stones by ultrasonic radiation force for treating tiny kidney stones, in particular to a physical direct therapy for treating tiny kidney stones, which belongs to the field of medical equipment. Background technique [0002] Kidney stone is a common and frequently occurring disease of the human urinary system. With the improvement of people's living standards and population growth, the incidence and number of kidney stones are increasing year by year. %, 50% over the age of 70, and an average per capita prevalence of about 10%. There are geographical differences in the incidence of kidney stones in my country. The incidence rate in the south is higher than that in the north. This may be related to water quality, climate and living habits. Yunnan Province is a province with a large incidence of kidney stones, and kidney stones account for more than 30% of urinary diseases. Kidney stones often cause urinary...

Problems solved by technology

[0004] In order to make up for the poor curative effect of current indirect treatment methods for small kidney stones, the present invention provides an ultrasonic radiation force stone removal device for small kidney stones, which includes an arbitrary waveform generator, a radio frequency power amplifier, a phased array Electronic focused ultrasonic transducer, the arbitrary waveform generator is connected to the phased array electronic focused ultrasonic transducer through a radio frequency power amplifier; the wave generated by the arbitrary waveform generator is amplified by the radio frequency power amplifier, and then passed through the phased array electronic focused ultrasonic transducer The device produces ultrasonic radiation focused on the micro-stones, making the micro-stones escape from the calices, enter the renal pelvis and ureter, and then be excreted through the urethra
