This report highlights steps taken from the beginning to the conclusion of the design and development of a functional high-Frequency electrosurgical unit, a device which uses high-frequency electric current to cut, coagulate and desiccate tissue for surgical effects by increasing intracellular temperature. Electrosurgical units have been around since the late nineteenth century but weren't commercialized until 1928 by William.T.Bovie and have advanced over the years but most electrosurgical units in developing countries are imported and thus are quite expensive. Because of this, electrosurgical units are scarce in most community clinics and rural healthcare facilities. These conditions inspired the conception of this project. The device was constructed using highly affordable materials and all work was done following three main objectives which were; parts and materials selection, CAD of both the circuitry and outer covering and the construction. The electrosurgical unit in this project uses a resonance and flyback driver mechanism to convert 220v 13A of A.C into 1Kv 5A current. By this method, a damped sinusoidal wave of a high frequency between 40 kHz-60kHz was achieved. The device was tested using a piece of meat and the frequency of current was measured using an oscilloscope. Several challenges were met along the way but the project was successful and a high-frequency electrosurgical unit was achieved.
