Vitrectomy-instrumentation-system MS 7.

An instrumentation-system (MS 7) for open-sky- as well as for pars-plana-vitrectomy is described. The intraocular canula is equipped with a special rotating cutting device. Suction is generated by a suction-pump in the power supply unit. Intraocular illumination is obtained by a detachable light pipe on the vitrectomy-canula or-for the bimanual technique-by a special hand-piece with infusion and fiber optic illumination. The infusion-canula in the hand-piece can be replaced by a micro-scissor with infusion-channel. Despite the motor the whole system can be easy cleaned and sterilized.
