Systems and methods for ocular surgery
View Patent ↗Ocular surgery may be performed by a variety of systems, processes, and techniques. In certain implementations, systems and processes for ocular surgery may include the ability to emulsify a lens in an eye using a modular hand-held system including a phacoemulsification unit detachably coupled to a pump unit and remove lens portions from the eye using suction provided by the pump unit. The system and the process may also include the ability to decouple the phacoemulsification unit from the pump unit, couple an irrigation-aspiration unit to the pump unit to form a second hand-held system, and remove material from the eye using suction provided by the pump unit.
1. A modular hand-held system for ocular surgery, the system comprising:
a hand-held phacoemulsification unit; and
a hand-held pump unit, the pump unit adapted to provide suction for aspirating material through the phacoemulsification unit, the pump unit comprising:
an adapter configured to detachably couple the phacoemulsification unit to the pump unit to form an integrated hand-held system;
a pumping portion comprising a fluid port; and
a drive portion comprising a slot, the fluid port receivable into the slot to secure the pumping portion to the drive portion,
wherein the pumping portion further comprises an inner shell that defines a cylindrical cavity, wherein the drive portion further comprises a rotor that is receivable into the cylindrical cavity upon coupling of the drive system to the pumping portion.
2. The system of claim 1 , wherein the phacoemulsification unit is adapted to receive suction from a surgical console for aspirating material from an eye.
3. The system of claim 1 , wherein the phacoemulsification unit comprises a male luer fitting, and the adapter comprises a female luer fitting.
4. The system of claim 3 , wherein the male luer fitting and the female luer fitting are engaged by a friction fit.
5. The system of claim 1 , wherein the adapter is composed of plastic.
6. A modular hand-held system for ocular surgery, the system comprising,
a hand-held phacoemulsification unit; and
a hand-held pump unit, the pump unit adapted to provide suction for aspirating material through the phacoemulsification unit, the pump unit comprising:
an adapter configured to detachably couple the phacoemulsification unit to the pump unit to form an integrated hand-held system;
a pumping portion comprising a fluid port; and
a drive portion comprising a slot, the fluid port receivable into the slot to secure the pumping portion to the drive portion,
wherein the slot comprises a transverse portion, and wherein the fluid port is made to reside within the transverse portion by rotation of the pumping portion relative to the drive portion.
7. A modular hand-held system for ocular surgery, the system comprising:
a hand-held phacoemulsification unit; and
a hand-held pump unit, the pump unit adapted to provide suction for aspirating material through the phacoemulsification unit, the pump unit comprising:
an adapter configured to detachably couple the phacoemulsification unit to the pump unit to form an integrated hand-held system;
a pumping portion comprising:
a fluid port; and
a cylindrical cavity; and
a drive portion comprising a rotor, the rotor receivable into the cylindrical cavity when the pumping portion and the drive portion are coupled together.
8. The system of claim 7 ,
wherein the drive portion further comprises:
a body defining an exterior surface of the drive portion; and
a slot formed in the body,
wherein the fluid port is received into the slot.
9. The system of claim 8 , wherein the slot comprises a transverse portion, and wherein the fluid port is made to reside within the transverse portion by rotation of the pumping portion relative to the drive portion.
