Abstract
A surgical hand piece has a connecting body having first and second passages detachably connected to first and second lumens which are used in the eye for phacoemulsification procedures and/or cleanup of the eye capsule after the procedure. The lumens receive or discharge fluid from first and second fluid sources. A work tip supporting the first and second tubes can be rotated so as to change the function of the first and second tubes from aspiration to irrigation and vice versa. As an alternative, a sleeve holding the fluid sources can be rotated so as to change the function of the first and second tubes from aspiration to irrigation and vice versa.

A surgical hand piece comprising:
- a connecting body having a distal end;
- a work tip having a proximal hub through which extend at least first and second tubes aligned side by side and adjacent to each other, said connecting body having first and second external openings, each of said tubes having a proximal end connected to separate passages in said connecting body leading to the external openings connectable to respective first and second fluid sources,
- said work tip being detachably connected to said connecting body distal end by a threaded collar (194) threaded on to threads at the distal end of said connecting body,
- wherein each of said first and second tubes has a lumen that is to receive or discharge a fluid at its proximal end from one of first and second fluid sources that are respectively irrigation and aspiration fluids, the lumen of each of said first and second tubes being separate and spaced apart, and each said tube having an opening at its distal end through which the fluid received at or discharged from the proximal end of the respective lumen of each said tube exits from or enters the tube, with each said tube distal end opening being separate, independent of, spaced from and without being in communication with the distal end opening of the other tube;
- and
- wherein the lumens of said work tip and the first and second fluid sources are rotatable with respect to each other so that in one operative position the first tube is in fluid communication with the first fluid source and the second tube is in fluid communication with the second fluid source, and in another operative position the first tube is in fluid communication with the second fluid source and the second tube is in fluid communication with the first fluid source.
A dual lumen work tip for an infusion/aspiration tool with concentric infusion and aspiration channels, comprising:
- a work tip housing,
- a central channel of the work tip for connection to the inner concentric channel of the infusion/aspiration tool,
- a lateral channel of the work tip for connection to the outer concentric channel of the infusion/aspiration tool, said lateral channel extending into the vicinity of the central channel and then running parallel with the central lumen,
- first and second lumens connected respectively to the central and lateral channels of the work tip, said lumens extending from the distal end of the housing and having openings at their distal ends.
A surgical hand piece comprising:
- a connecting body having a distal end;
- a work tip having a hub from which extend at least first and second tubes aligned side by side and adjacent to each other, each of said tubes having a proximal end selectively connectable to separate first and second passages in said connecting body which lead to external openings connected to first and second fluid sources, said hub being detachably connected to said connecting body distal end by means of threads on the hub,
- each of said first and second tubes has a lumen that is to receive or discharge a fluid at its proximal end from one of the first and second passages, which fluids are respectively irrigation and aspiration fluids, the lumen of each of said first and second tubes being separate and spaced apart, and each said tube having an opening at its distal end through which the fluid received at or discharged from the proximal end of the respective lumen of each said tube exits from or enters the tube, with each said tube distal end opening being separate, independent of, spaced from and without being in direct communication with the distal end opening of the other tube;
- and
- wherein the lumens of said work tip with their hub and the first and second passages are rotatable with respect to the fluid passages so that in one operative position the first tube is in fluid communication with the first fluid source and the second tube is in fluid communication with the second fluid source, and in another operative position the first tube is in fluid communication with the second fluid source and the second tube is in fluid communication with the first fluid source.
A surgical hand piece comprising:
- a connecting body having a distal end;
- first and second tubes located toward the distal end of the connecting body and aligned side by side and adjacent to each other, each of said tubes having a proximal end connectable to separate first and second passages in said connecting body leading to external openings from said body,
- a sleeve mounted on a first reduced diameter portion of the connecting body, first and second fluid passages in said sleeve connected between first and second fluid sources and the first and second passages in said connecting body,
- a collar threaded on to a second reduced diameter portion of the connecting body and supporting the sleeve when tightened, but when loose the sleeve is rotatable about the first reduced diameter portion of the connecting body,
- each of said first and second tubes has a lumen that is to receive or discharge a fluid at its proximal end from one of the first and second passages, which fluids are respectively irrigation and aspiration fluids, the lumen of each of said first and second tubes being separate and spaced apart, and each said tube having an opening at its distal end through which the fluid received at or discharged from the proximal end of the respective lumen of each said tube exits from or enters the tube, with each said tube distal end opening being separate, independent of, spaced from and without being in communication with the distal end opening of the other tube;
- and
- wherein the sleeve along with the first and second fluid passages as well as the first and second fluid sources can be rotated about the first reduced diameter portion of the connecting body so that in one operative position the first tube and the first passage of the connecting body are in fluid communication with the first fluid passage of the sleeve and the first fluid source, and the second tube and the second passage of the connecting body are in fluid communication with the second fluid passage of the sleeve and the second fluid source, while in another operative position the first tube and the first passage of the connecting body are in fluid communication with the second fluid passage of the sleeve and the second fluid source, and the second tube and the second passage of the connecting body are in fluid communication with the first fluid passage of the sleeve and the first fluid source.
A surgical hand piece comprising:
