[Abstract]:Pathological tissue processing is the process of extracting and treating the pathological tissues of patients. The degree of cytopathology, metastasis and diffusion is judged by observing and studying the morphological structure and changes of tissues. The treatment of pathological tissue involves cell fixation, wax immersion, tissue cell processing, section making and staining. The treatment of histocytes is an indispensable link in the treatment of pathological tissues. Ultrasonic power amplifier is the core part of the rapid pathological tissue product, which determines the quality and speed of tissue cell processing, and has a direct impact on the treatment of patients. Rapid histopathology can save time for clinical histocyte examination and can be used for screening large-scale cancer in hospitals. Because most of the pathological products are developed by foreign companies, the number of domestic companies engaged in the development of such products is relatively few, resulting in the lack of pathological products in the domestic market. The hospital buys the equipment from the foreign expensive, the maintenance cost is high. Under this background, this paper studies the ultrasonic power amplifier of the rapid pathological tissue nuclear. The purpose is to develop a high efficient and stable ultrasonic power amplifier. Ultrasonic power amplifier is an applied research subject. Therefore, the demand of enterprise is considered in the process of product design. The ultrasonic power amplifier is divided into several modules, including signal source circuit, drive circuit, load circuit, isolation circuit and power supply. This paper focuses on the following aspects: first, the introduction of the paper describes the background and research significance of ultrasonic power amplifier, summarizes the development process and trend of ultrasonic power amplifier. The current situation of ultrasonic power amplifier is analyzed, and the work plan of the thesis is worked out. Secondly, the concept and working flow of ultrasonic power amplifier are introduced. The principle of half bridge and full bridge are briefly described, and the advantages and disadvantages of the two modes are compared. Thirdly, the circuit principle and design of ultrasonic power amplifier are introduced, including signal source chip, driver chip and MOSFET transistor. The principle of the full bridge circuit, the typical circuit of the drive chip and the optimum design of the circuit are analyzed, and the problems found in the course of the research are solved. Fourthly, the system composition of STM32 chip is introduced, the theoretical knowledge of clock tree and timer, the introduction and configuration steps of software development platform, the train of thought of programming and the initialization of program, the downloading and debugging of signal are introduced in detail. Fifthly, it introduces the circuit board making, debugging and summing up prospect, including device selection, circuit layout, wiring rules of power cord and signal wire in the process of circuit board design. The system of ultrasonic power amplifier is debugged, and some debugging results are shown. The work done is summarized, and the improvement of ultrasonic power amplifier is put forward.
