Problems solved by technology

However, in the existing technology, each frequency module of the host is usually set separately and needs to be configured with different start switches, so that different frequencies correspond to different functional circuit boards, which leads to the need for a large internal accommodation space on the one hand and the volume of the host device. Larger, on the one hand, due to the presence of multiple jacks on the host, there will be situations where the execution device (such as a gravel device) does not match the jack, resulti

Embodiment approach 1

[0058] Such as Figure 4 As shown, the multi-frequency generation system includes a signal acquisition unit 101, a signal generation unit 102 and a micro-processing unit 103, wherein a single-chip integrated structure is adopted, and at least the signal generation unit 102 is integrated on one chip. Further, the signal acquisition unit 101 , a signal generation unit 102 and a micro-processing unit 103 are integrated on a circuit board.

[0059] Specifically, the micro-processing unit 103 can be, for example, an FPGA control chip, which is used to control each unit. Exemplarily, the micro-processing unit 103 controls the signal acquisition unit 101 and the signal generation unit 102 , and then generates various frequency signals through the signal generation unit 102 .

[0060] The signal acquisition unit 101 includes a signal communication module, an AD conversion module and a modulation module. The signal acquisition unit 101 is used to receive a feedback signal (echo signa...

Embodiment approach 2

[0072] The difference between the second embodiment and the first embodiment is only that: on the basis of the first implementation of the technical solution, such as figure 2 As shown, an automatic detection excitation circuit is added to the signal generating unit 102, which is used to automatically identify the ultrasonic resonance frequency of the connected ultrasonic surgical execution unit 200, and automatically adapt the corresponding excitation circuit to output the ultrasonic excitation signal, Then the surgical execution unit is driven. The automatic identification function of the automatic detection and excitation circuit helps to avoid input or selection errors when using manual input / selection of the type of ultrasonic surgical execution unit 200 as described in the first embodiment, which in turn leads to subsequent frequency selection output error, affecting the normal operation of the device.

[0073] The automatic detection excitation circuit in the signal g...

Abstract

The invention discloses a multi-frequency ultrasonic generation system for urinary system ultrasonic equipment. The multi-frequency ultrasonic generation system comprises a signal acquisition unit, a signal generation unit and a micro-processing unit, wherein the signal generation unit comprises a control switch module and N parallel excitation circuits; the control switch module is used for receiving an instruction of the micro-processing unit; the N parallel excitation circuits are electrically connected with the control switch module; the signal generation unit is integrated on a single chip; the N parallel excitation circuits can generate N frequencies, and N is an integer which is greater than or equal to 2; and the generated frequencies at least comprise 55-70kHz frequencies for urinary system lithotripsy. According to the multi-frequency ultrasonic generation system, the integration of host functions is realized, a high-low frequency output mode is realized, the equipment size is reduced, and particularly the high-frequency lithotripsy success rate of a urinary system is realized; and the multi-frequency ultrasonic generation system has a wide medical application prospect.

Description

technical field [0001] The present disclosure relates to a multi-frequency ultrasonic generating system, and more specifically, to a multi-frequency ultrasonic generating system used in urological ultrasonic equipment. Background technique [0002] In recent years, interventional minimally invasive surgery is the main treatment for urinary stones. In this type of minimally invasive surgery, ultrasound is often used as an energy source in lithotripters. In existing ureter lithotripsy machines that use ultrasound as an energy source, the ultrasonic frequency used is usually not higher than 25kHz, and in the existing ureter lithotripsy, an ultrasonic generator (host) usually only outputs one frequency, and is equipped with a Fixed frequency surgical instruments. [0003] Aiming at the technical problem of single function and single frequency of the ureteral ultrasonic lithotripsy device and the demand for the integration of host functions during the operation, those skilled in...
