Special instruments have been perfected for the laser microsurgery. Those instruments must not exceed 18 centimeters in length in order to reduce the possibility of infection through the middle part (microslad) tied up to the microscope. The instruments must be blackened to reduce the casual reflection of the laser ray over the intra-abdominal structures. Molybdenum mirrors with specifically outlined angles to reflect laser rays towards the inaccessible spots and also to strike the aimed tissue at the right place, have been perfected. In the same way, quartz straight and angular rods stronger to the laser fatigue than the pyrex are necessary to absorb laser energy during the vaporization and the excision of intra-pelvic adhesions. Thanks to these adapted instruments, the micro surgeon gynecologist will be able to practise his laser surgery with more safety, less eyestrain and less difficulties.
