Abstract
The present disclosure relates to an assembly operable with an intraocular lens (IOL) injection device. The assembly includes an electric motor and a control device. The electric motor is configured to generate rotational motion and includes a stator and a drive shaft. The stator or the drive shaft is removably couplable to an adjustment knob of the IOL injection device. The control device is communicatively coupled to the electric motor and is configured to control operation of the electric motor. The stator or the drive shaft is configured to rotate the adjustment knob relative to a body and a plunger rod of the IOL injection device in response to the rotational motion.
Claims20
An assembly operable with an intraocular lens (IOL) injection device, the assembly comprising:
- an electric motor configured to generate rotational motion, the electric motor comprising a stator and a drive shaft, the stator or the drive shaft removably couplable to an adjustment knob of the IOL injection device;
- and
- a control device communicatively coupled to the electric motor and configured to control operation of the electric motor;
- wherein the stator or the drive shaft is configured to rotate the adjustment knob relative to a body and a plunger rod of the IOL injection device in response to the rotational motion.
An assembly operable with an intraocular lens (IOL) injection device, the assembly comprising:
- a flex shaft cable comprising a first end couplable to an electric motor configured to generate rotational motion and a second end couplable to an adjustment knob of the IOL injection device;
- a first connector at the first end of the flex shaft cable and configured to couple the first end of the flex shaft cable to the electric motor;
- and
- a second connector at the second end of the flex shaft cable and configured to couple the second end of the flex shaft cable to the adjustment knob;
- wherein the flex shaft cable is configured to transmit the rotational motion from the electric motor and the second connector is configured to rotate the adjustment knob in response to the rotational motion transmitted through the flex shaft cable.
A method of delivering an intraocular lens (IOL) comprising:
- attaching a connector to an adjustment knob of an IOL injection device, wherein the connector is coupled to a flex shaft cable;
- activating an electric motor mechanically coupled to the flex shaft cable to generate rotational motion;
- transmitting the rotational motion from the electric motor through the flex shaft cable and the connector to the adjustment knob;
- and
- rotating the adjustment knob of the IOL injection device to advance an IOL relative to the IOL injection device.
