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.Kombinovani koaksijalni i bimanuelni irigacioni/aspiracioni sklop (100) za korišćenje u hirurškoj proceduri obuhvata: irigacioni instrument (102) koji ima irigacionu iglu (114), koja se pruža od daljeg završetka (112) irigacionog instrumenta, gde je irigaciona igla oblikovana tako da ispušta irigacioni fluid iz sklopa； aspiracioni instrument (104) koji ima aspiracionu iglu (128) koja se pruža od daljeg završetka (126) aspiracionog instrumenta i aspiraciona igla ima osu i oblikovana je da usisava fluid u sklop, naznačen time, što sklop (100) zatim obuhvata: čauru 106, pri čemu čaura spaja irigacioni instrument (102) i aspiracioni instrument (104) u jednu celinu kada je sklop u prvom obliku, gde čaura ima unutrašnji kanal (142) i dalji završeci (112, 126) aspiracionog i irigacionog instrumenta su oblikovani tako da se pružaju u kanal da bi se spojili dalji završeci aspiracionog i irigacionog instrumenta sa čaurom； pri čemu sklop ima prvi oblik u kome su irigacioni instrument (102) i aspiracioni instrument (104) povezani u jednu celinu tako da se aspiraciona igla (12
