Abstract
A length of tubing 20 includes an irrigation lumen 26 for carrying irrigation fluid from a source 12 to an ophthalmic surgical site at eye 18. An aspiration lumen 28 is also formed in tubing 20 for carrying aspirant from the surgical site at eye 18 to a collection reservoir. The irrigation lumen 26 and the aspiration lumen 28 include a compliant common wall 30. Wall 30 ensures that any surge occurring after an occlusion break during surgery is dampened because of the compliant common wall 30.
Claims10
An irrigation and aspiration tubing length for use in ophthalmic surgery comprising:
- a length of tubing including an irrigation lumen for carrying irrigation fluid from a source to an ophthalmic surgical site and an aspiration lumen for carrying aspirant from the surgical site to a collection reservoir;
- and
- wherein the irrigation and aspiration lumens include a compliant common wall, such that any surge occurring after an occlusion break is dampened because of the compliant common wall.
An ophthalmic surgical system comprising:
- a source of irrigation fluid;
- an aspiration pumping source;
- a surgical handpiece for infusing irrigation fluid into a patient's eye and for aspirating fluids and tissue away from the eye;
- a length of tubing connecting the surgical handpiece to each of the irrigation fluid source and the aspiration pumping source;
- and
- wherein at least a portion of the length of tubing includes an irrigation lumen for carrying irrigation fluid and an aspiration lumen for carrying aspirant fluid and tissue, such that the irrigation and aspiration lumens include a compliant common wall, such that any surge occurring after an occlusion break is dampened because of the compliant common wall.
