Abstract

A flexible sheath is attached to an end of a rigid extension tube. The other end of the rigid extension tube is connected with a surgical handpiece. Two flexible sheaths may be used—one as a barrier against contamination of aspiration tubing and the other as a barrier against contamination of irrigation tubing. This is effected by securing two rigid extension tubes between the surgical handpiece and an associated one of the aspiration and irrigation tubings. Each flexible sheath is collapsible and expandable so they may be expanded from a collapsed condition over the associated aspiration or irrigation tubings and secured in the expanded condition. The aspiration and/or irrigation tubings are connected to a cassette of a surgical pack.

Claims (9)

1. A sterilized barrier apparatus, comprising:

a sterile, tubular sheath that is configured to displace between expanded and collapsed conditions;

a hollow extension tube secured to a distal end of the sterile, tubular sheath; and

an instrument console with a surgical pack that includes an aspiration tube having a distal end to which is attached the hollow extension tube, the aspiration tube projecting from the instrument console, the sterile, tubular sheath being arranged to contain the aspiration tube within confines of the sterile, tubular sheath between the hollow extension tube and the instrument console and thereby serve as sterilized barrier against exposure of the aspiration tube to contamination, the sterile tubular sheath being secured to either an end of the aspiration tube in close proximity to the port, or the port of the console.

2. A sterilized barrier apparatus of claim 1 , wherein the surgical pack includes a cassette arranged to receive contents of the aspiration tube that are being aspirated, the aspiration tube having a proximal end closer to the cassette than the distal end of the aspiration tube, a location where the sterile, tubular sheath is secured to the aspiration tube being closer to the proximal end than to the distal end of the aspiration tube.

3. A sterilized barrier apparatus of claim 1 , wherein the instrument console has a suction pump that, when activated, suctions the aspiration tube.

4. A sterilized barrier apparatus of claim 1 , further comprising a surgical handpiece attached to the distal end of the aspiration tube.

5. A sterilized barrier apparatus of claim 1 , wherein a surgical handpiece is attached to a distal end of the hollow, extension tube.

6. A sterilized barrier apparatus of claim 1 , wherein the sterile, tubular sheath is configured so as to be collapsible into the collapsed condition in an accordion fashion.
