A microsurgical cutting device (20) for cutting tissue, such as ocular tissue is disclosed. The device includes a handle body (24), a linear actuator (26) carried within the body (24) for movement of an armature (28) between retracted and extended positions, typically through an excursion of between about 50-100 mils, and a circuit which can drive the actuator (26) in a proportional or slow oscillatory modes. The device is designed to engage a cutting tool assembly (80), preferably a disposable assembly, through a two-clamp structure (78, 79) which holds one part of the assembly (80) stationary and connects a cutting tool (88) in the assembly to the actuator's armature. |
