摘要: Electric vitrectomy handpieces are provided. The handpiece includes a motor, a clutch mechanism, an oscillating drive mechanism, a cutting tip and a handle. The motor is attached to the clutch, and the clutch is attached to the oscillating drive mechanism. When the motor is operational, the clutch expands to engage the oscillating drive mechanism and the oscillating drive mechanism converts the rotational motion of the clutch to the reciprocating motion of the cutting tip. When the motor is at rest, the clutch retracts to allow aspiration.
