In recent years motor driven hand instruments for especially difficult microsurgical manipulations have come in use. Under certain conditions the electric low volt systems presented difficulties with regard to power or reliability. Therefore trials were made with pneumatic systems which with same dimensions produce much more power. In this way also totally different functions can be remote-controlled in quite a new way.
近年来，用于特别困难的显微外科手术操作的电动手持器械开始投入使用。在某些情况下，低电压电动系统在功率或可靠性方面存在困难。因此，人们对气动系统进行了试验，在相同尺寸的情况下，气动系统能产生更大的功率。通过这种方式，完全不同的功能也可以以一种全新的方式进行远程控制。
