Abstract
An intraocular lens inserter can include an energy storage portion, an actuator portion, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid, such as liquids or other noncompressible fluids. The actuator can be configured to provide an operator with control over the release of energy from the energy storage portion so as to move a plunger for the discharge of a lens from an intraocular lens cartridge.
Claims25
An intraocular lens inserter comprising:
- A compressed gas storage portion comprising a compressed gas cartridge configured to release a compressed gas into the compressed gas storage portion;
- a hydraulic portion containing a substantially incompressible fluid;
- a moveable member disposed between the compressed gas cartridge and the hydraulic portion and configured to impart pressure of the released compressed gas in the compressed gas storage portion to the substantially incompressible fluid in the hydraulic portion;
- an actuator portion comprising an actuator member and a plunger mounted for sliding movement between a retracted position and an extended position, the actuator portion configured to allow a user to control a flow of the substantially incompressible fluid through the hydraulic portion to move the plunger from the retracted position to the extended position by using the actuator member;
- and
- an intraocular lens retaining portion comprising an intraocular lens for insertion into an eye of an animal and aligned with the plunger such that the plunger pushes the intraocular lens when the plunger moves from the retracted position toward the extended position.
An intraocular lens inserter comprising:
- an intraocular lens retaining portion comprising an intraocular lens;
- a compressed gas storage portion comprising a compressed gas cartridge configured to release a compressed gas into the compressed gas storage portion;
- a hydraulic portion containing a substantially incompressible fluid;
- a moveable member disposed between the compressed gas cartridge and the hydraulic portion and configured to impart pressure of the released compressed gas in the compressed gas storage portion to the substantially incompressible fluid in the hydraulic portion;
- an actuator portion comprising a plunger, the actuator portion communicating with the compressed gas storage portion and configured to allow a user to control a flow of the substantially incompressible fluid through the hydraulic portion to move the plunger via the substantially incompressible fluid for discharging the intraocular lens.
An intraocular lens inserter comprising:
- an intraocular lens receiving portion comprising an intraocular lens for insertion into an eye of an animal;
- a compressed gas storage portion comprising a compressed gas cartridge configured to release a compressed gas into the compressed gas storage portion;
- a hydraulic portion containing a substantially incompressible fluid;
- a moveable member disposed between the compressed gas cartridge and the hydraulic portion and configured to impart pressure of the released compressed gas in the compressed gas storage portion to the substantiality incompressible fluid in the hydraulic portion;
- a plunger configured to contact the intraocular lens and discharge the intraocular lens from the intraocular lens receiving portion;
- and
- a means for allowing a user to control a flow of the substantiality incompressible fluid through the hydraulic portion to move the plunger.
