The ultrasonic generator generates a signal of a specific frequency. This signal can be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the ultrasonic transducer. Generally, there are many ultrasonic frequencies used in ultrasonic equipment. With the continuous development of technology, it is believed that the application area will gradually expand. A relatively complete generator should also have a feedback link, which mainly provides feedback signals in two aspects.
Single chip microcomputer has the advantages of fast speed, strong function, high efficiency, small size, reliable performance, strong anti-interference ability, etc., and is widely used in various control systems. The CPU of single chip microcomputer has gone through the development process from 4, 8,16, 32 to 64 bits. In the ultrasonic transducer used in a medical, single chip microcomputer is mainly used for data acquisition and operation processing, voltage and current regulation, PWM signal generation, system status monitoring and fault self-diagnosis, etc. It is generally operated as the main control chip of the whole circuit and completes various comprehensive functions. Cooperate with converter and power module to realize pulse width modulation.
Ultrasonic system in the system application design, or various types of processing applications, all need to be effective and stable to be fixed; a set of ultrasonic vibration system will generally include ultrasonic generator, transducer, horn, ultrasonic welding head. Medical ultrasonic transducers, horn, and ultrasonic welding head are all resonators, so the fixed method and position must be precisely designed. Otherwise, the light ones will affect the resonance of the ultrasonic vibration system, and even cause damage to the ultrasonic vibration system.
Ultrasonic transducer is an energy conversion device, which is also known as ultrasonic vibrator and ultrasonic vibrator. Its function is to convert the input electrical power into mechanical power (ultrasonic waves) and then transmit it out, while itself consumes a small part of the power (less than 10%). Therefore, the most important issue to consider when using ultrasonic transducers is the matching with the input and output terminals, followed by mechanical installation and matching dimensions. There are many kinds of ultrasonic machinery on the market, and customers must provide accurate and reliable indicators to ensure that the transducer products provided by the company can be well matched with your company's machines and exert the best performance. Due to the variety of ultrasonic transducers, this article only provides some ultrasonic transducer parameters.
Let the ultrasonic transducer, generator ultrasonic drive power supply and ultrasonic mold cooperate well to form a complete ultrasonic equipment, which can be referred to as matching. Since the impact of matching on the performance of the whole machine is decisive, it is necessary to emphasize the importance of matching. The most important factor for matching is the capacitance of the ultrasonic transducer, followed by the frequency of the transducer.
Ultrasonic scalpel is usually composed of ultrasonic power supply, hand-held treatment head and auxiliary equipment. Through this set of system devices, electrical energy is converted into mechanical energy of ultrasonic vibration, which is output by the front end of the ultrasonic hand-held treatment head, instead of ordinary scalpels. In order to achieve the purpose of surgical treatment, it is also called ultrasonic knife or ultrasonic scalpel. Ultrasonic scalpel is widely used in surgical procedures because they are suitable for incisions in soft tissue where bleeding control and minimal thermal damage are required. Ultrasonic scalpel can also be used to complement or replace high-frequency scalpels, laser scalpels and steel scalpels, thus greatly broadening the application fields of ultrasound therapy.
Many people don't know the difference between ultrasonic sensors, ultrasonic probes and ultrasonic transducers, considering that these three are the same product. BBT will introduce the difference between ultrasonic sensors, ultrasonic probes and ultrasonic transducers.
