Power supply for bipolar electrodes for capsulotomy

摘要: A bipolar diathermal instrument is fed a pulsed RF current in order to carry out an incision optimally capsulotomy. The working pulse width can be continuously varied between 3 ms and 11 ms, resulting pause of 30 22 respectively. This sufficient cool the tip, which flushed with sodium chloride, so that no damage adjacent tissue occur. repetition frequency approximately 15 Hz. equipment required for this purpose comprises control (31) oscillator (30). clocked by pulses from means AND gate (35). An amplifier (40) feeds handset (21) via transformer (46), thus ensuring desired operation free earth potential.
