A new system of trepanation based on a firm mechanical guide of the rotor trepan is described. Apart from the well-known advantages of the electrically driven trepan, further considerable improvements are evident. As here the rotor instrument is guided mechanically, the risky and important phase of corneal incision in keratoplasty is considerably less dangerous. With this instrument, the incision becomes much safer, the centring of the trepan becomes easier and an unintentional injury of iris and lens may be considerably avoided.
描述了一种基于转子环钻坚固机械导向的新型环钻系统。除了电动环钻的众所周知的优点外，还明显有进一步的显著改进。由于这里转子器械是机械导向的，角膜移植术中角膜切口这一危险且重要的阶段危险性大大降低。使用这种器械，切口变得更加安全，环钻的定心变得更容易，并且可以相当程度地避免虹膜和晶状体的意外损伤。
