Flexural Transducer Based Monolithic Diathermy Probe for Thermo Therapy

Ultrasound diathermy is one of the most commonly used therapeutic techniques for muscle injuries and chronic pain. However, the traditional machines are large and inconvenient, thus limiting their application. This project will be developed to miniaturize and make a portable ultrasound diathermy probe with all the essential components power source, ultrasound transducer, control unit, and coupling mechanism all in one easy-to-use device. The proposed probe measures approximately 30 cm in length, 4 cm in diameter and weight of 15 gram making it significantly smaller than traditional diathermy units. The objective is the design of a compact, ergonomic probe in which all components have been merged to minimize dimensions, to enhance portability and improve user comfort. The designed system includes a high-frequency generator, power amplifier, and battery management system for optimal heat generation and delivery. The device operates at a frequency range of 1.77 MHz, with a power supply of 3.7V, 1000mAh rechargeable lithium-ion battery, ensuring efficient portability and extended usage. The Monoprobe Diathermy is the improvement over other systems in usability, portability, and therapeutic outcome, overcoming limitations of conventional systems. It will be tested further to establish its feasibility in clinical settings.
