Problems solved by technology

The existing dedicated ultrasonic postpartum uterine treatment equipment is not only bulky, but also complicated to operate, poorly configurable, and low in treatment efficiency, and only supports dynamic treatment modes, and the ultrasonic equipment used for postpartum uterine treatment requires doctors to constantly move the probe. To prevent the generation of treatment hot spots

Embodiment Construction

[0047] The purpose of the present invention is to provide an array type ultrasonic treatment system to realize low-intensity static ultrasonic treatment.

[0048] In order to make the above objects, features and advantages of the present invention more comprehensible, the invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] The invention adopts the ultrasonic phased array technology, each array element can be controlled independently, the generation of cavitation is monitored through the detection function of the ultrasonic transducer, and the corresponding relationship between the cavitation threshold and the sound pressure is used to estimate the extreme value of the sound intensity, and Larger sound intensity often causes the occurrence of tissue hot spots.

[0050] The static treatment of low-intensity ultrasound can be realized by applying the system of the invention. The ultrasonic therapy s...

Abstract

The invention discloses an array type ultrasonic therapy system. The ultrasonic therapy system includes: an ultrasonic therapy control unit, an ultrasonic transducer drive array, and an ultrasonic transducer array; the ultrasonic transducer array includes n ultrasonic transducer arrays. device; the detection signal output end of the ultrasonic transducer used to detect the ultrasonic echo produced by ultrasonic therapy is connected to the feedback signal input end of the ultrasonic therapy control unit; the control signal output end of the ultrasonic therapy control unit is connected to the The input end of the ultrasonic transducer driving array is connected, and the output end of the ultrasonic transducer driving array is connected with the driving end of the ultrasonic transducer used for ultrasonic treatment. The present invention monitors the treatment area through the ultrasonic transducer used to detect the ultrasonic echo generated by the ultrasonic treatment, and when it is determined that the probability of hot spots is relatively high, the treatment sound intensity and the treatment sound intensity of the ultrasonic transducer array are adjusted by the ultrasonic treatment control unit. Deflection focus to achieve low-intensity static ultrasound therapy.

Description

technical field [0001] The invention relates to the technical field of ultrasound therapy, in particular to an array type ultrasound therapy system. Background technique [0002] The biological effect of low-intensity ultrasound has been paid attention to in recent years, and ultrasound physiotherapy equipment based on its principle has been widely used in clinic. In 1978, scientists discovered for the first time that low-intensity focused ultrasound could stimulate the amplitude and frequency of uterine contractions in mice. Accelerated uterine contraction has the function of hemostasis, and clinically, postpartum hemorrhage has always been the number one killer of maternal death. Since ultrasound equipment is universal, different protocols can be compiled according to the purpose of treatment, but there are few dedicated postpartum uterine involution equipment. The existing dedicated ultrasonic postpartum uterine treatment equipment is not only bulky, but also complicate...
