Ultrasonic treatment equipment

Abstract

The invention provides ultrasonic treatment equipment. The ultrasonic treatment equipment comprises an ultrasonic transduction transmitter, an ultrasonic transduction receiver, a judgment device and a feedback control device, wherein an ultrasonic transduction transmitter is used for generating and transmitting ultrasonic wave to an active area, an ultrasonic transduction receiver is used for collecting sound signals from the active area and converting the collected sound signals into electric signals, a judgment device is used for judging whether the active area has an acoustic cavitation in a preset strength range to acquire a judgment result, and a feedback control device is used for controlling the ultrasonic transmission dosage of the ultrasonic transduction transmitter when the judgment result indicates that the acoustic cavitation of the active area is not in the preset strength range, so that the acoustic cavitation of the active area is in the preset strength range. According to the ultrasonic treatment equipment, the accuracy of ultrasonic acoustic cavitation control means is improved, and the treatment effect is ensured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to ultrasonic treatment equipment. Background technique [0002] High-intensity ultrasonic signals can produce several biological tissue effects in human tissues, such as thermal necrosis of cells due to tissue absorption of ultrasonic energy, cell rupture and apoptosis due to mechanical effects of ultrasonic waves. [0003] Ultrasonic cavitation is a mechanical effect of ultrasonic waves, which is a physical phenomenon caused by high-intensity ultrasonic waves acting on cavitation nuclei (tiny bubbles) in liquids or quasi-liquids. Micro-bubbles are repeatedly driven by the positive and negative pressure of the sound wave to produce alternate rapid volume growth and compression, and the bubble expansion and contraction movement caused by the alternating sound pressure is called steady-state cavitation. When the bubble expands and contracts rapidly and causes the mechani...

Problems solved by technology

Therefore, this kind of method can only infer the actual biological tissue effect from the change of the emitted electrical signal according to experience, which is only a kind of reasoning, not the actual situation, so there is the possibility of misjudgment and the disadvantage of low accuracy

These disadvantages can jeopardize the safety and efficacy of treatment
