Abstract

In one exemplary aspect, the present disclosure is directed to an assembly having an irrigation hand piece that includes an irrigation needle extending from a distal end. The irrigation needle is also configured to release a first fluid. The assembly further has an aspiration hand piece that includes an aspiration needle extending from a distal end. The aspiration needle has an axis and is configured to aspirate a second fluid into the assembly. The assembly has a first configuration in which the irrigation hand piece and aspiration hand piece are coupled together in a manner that causes the released first fluid from the assembly to flow coaxially about the axis of the aspiration needle and a second configuration in which the irrigation hand piece and aspiration hand piece are uncoupled which causes the released first fluid to flow substantially non-coaxial with respect to the axis of the aspiration needle.

Claims13

Dependent claims

An assembly comprising:

an irrigation hand piece including an irrigation needle extending from a distal end of the irrigation hand piece, the irrigation needle configured to release an irrigation fluid from the assembly;
an aspiration hand piece including an aspiration needle extending from a distal end of the aspiration hand piece, the aspiration needle having an axis and being configured to aspirate an aspirated fluid into the assembly;
and
a sleeve member, the sleeve member coupling the irrigation hand piece and the aspiration hand piece together when the assembly is in the first configuration wherein the sleeve member has an internal bore and the distal ends of the aspiration and irrigation hand pieces are configured to extend into the bore to couple the distal ends of the aspiration and irrigation hand pieces to the sleeve member;
wherein the assembly has a first configuration in which the irrigation hand piece and aspiration hand piece are coupled together such that the irrigation needle is substantially parallel to the aspiration needle and the aspiration needle is located along a central axis of the irrigation and aspiration hand pieces in the first configuration and a second configuration in which the irrigation hand piece and aspiration hand piece are uncoupled such that the irrigation needle is not substantially parallel to the aspiration needle and the aspiration needle is located near a periphery of the aspiration hand piece in the second configuration.

An assembly comprising:

an irrigation hand piece including an irrigation needle extending from a distal end of the irrigation hand piece, the irrigation needle configured to release an irrigation fluid from the assembly;
an aspiration hand piece including an aspiration needle extending from a distal end of the aspiration hand piece, the aspiration needle having an axis and being configured to aspirate an aspirated fluid into the assembly;
and
a sleeve member selectively attachable to the irrigation and aspiration hand pieces and shaped so that when in a first configuration the sleeve member couples the irrigation hand piece and the aspiration hand piece together such that the irrigation needle is substantially parallel to the aspiration needle and the aspiration needle is located along a central axis of the irrigation and aspiration hand pieces in the first configuration and a second configuration detached from the irrigation hand piece and the aspiration hand piece such that the irrigation needle is not substantially parallel to the aspiration needle and the aspiration needle is located near a periphery of the aspiration hand piece in the second configuration;
wherein the sleeve member has an internal bore such that in the first configuration a distal end of each of the aspiration and irrigation hand pieces extends into the internal bore to couple the sleeve member.

An assembly comprising:

an irrigation hand piece including an irrigation needle extending from a distal end of the irrigation hand piece, the irrigation needle configured to release an irrigation fluid from the assembly;
an aspiration hand piece including an aspiration needle extending from a distal end of the aspiration hand piece, the aspiration needle having an axis and being configured to aspirate an aspirated fluid into the assembly;
and
a sleeve member selectively attachable to the irrigation and aspiration hand pieces and shaped so that when in a first configuration the sleeve member couples the irrigation hand piece and the aspiration hand piece together such that the irrigation needle is substantially parallel to the aspiration needle and the aspiration needle is located along a central axis of the irrigation and aspiration hand pieces in the first configuration and a second configuration detached from the irrigation hand piece and the aspiration hand piece such that the irrigation needle is not substantially parallel to the aspiration needle and the aspiration needle is located near a periphery of the aspiration hand piece in the second configuration;
wherein the irrigation hand piece and aspiration hand piece each have a substantially semi-circular cross-section shape such that when the sleeve is in the first configuration the assembly has a substantially circular cross-section shape;
and wherein the sleeve member has an internal bore such that in the first configuration a distal end of each of the aspiration and irrigation hand pieces extends into the internal bore to couple the sleeve member.
