An assembly for a phacoemulsification surgical system, comprising: a phacoemulsification hand piece; an irrigation system configured to provide irrigating fluid to the phacoemulsification hand piece to irrigate a surgical site; and an aspiration system arranged to aspirate aspirating fluid from the surgical site, the aspiration system comprising: an aspiration path within the phacoemulsification hand piece; a flexible small bore aspiration tubing configured to be in fluid communication with the aspiration path of the phacoemulsification hand piece, the small bore aspiration tubing having a nominal inner diameter smaller than about 1.27 mm (.050 inch) to reduce levels of occlusion surge within the surgical system, the inner diameter being substantially consistent through the length of the small bore aspiration tubing; and a peristaltic pump in communication with the small bore aspiration tubing operable to create a flow through the small bore aspiration tubing; wherein the small bore aspiration tubing comprises a flared portion on the inner diameter of at least one end, wherein when in an unloaded condition, the flared portion has an inner diameter larger than the nominal inner diameter of the small bore aspiration tubing; a connector (330, 332) is configured to receive at least a portion of the flared portion of the small bore aspiration tubing, the connector (330, 332) being sized to apply radial compression on the flared portion when the flared portion is inserted in the connector (330, 332) such that when the small bore aspiration tubing is disposed within the connector (330, 332), the inner diameter of the flared portion is about the same diameter as the nominal diameter of the small bore aspiration tubing. a phacoemulsification hand piece; an irrigation system configured to provide irrigating fluid to the phacoemulsification hand piece to irrigate a surgical site; and an aspiration system arranged to aspirate aspirating fluid from the surgical site, the aspiration system comprising: an aspiration path within the phacoemulsification hand piece; a flexible small bore aspiration tubing configured to be in fluid communication with the aspiration path of the phacoemulsification hand piece, the small bore aspiration tubing having a nominal inner diameter smaller than about 1.27 mm (.050 inch) to reduce levels of occlusion surge within the surgical system, the inner diameter being substantially consistent through the length of the small bore aspiration tubing; and a peristaltic pump in communication with the small bore aspiration tubing operable to create a flow through the small bore aspiration tubing; wherein the small bore aspiration tubing comprises a flared portion on the inner diameter of at least one end, wherein when in an unloaded condition, the flared portion has an inner diameter larger than the nominal inner diameter of the small bore aspiration tubing; a connector (330, 332) is configured to receive at least a portion of the flared portion of the small bore aspiration tubing, the connector (330, 332) being sized to apply radial compression on the flared portion when the flared portion is inserted in the connector (330, 332) such that when the small bore aspiration tubing is disposed within the connector (330, 332), the inner diameter of the flared portion is about the same diameter as the nominal diameter of the small bore aspiration tubing. an aspiration path within the phacoemulsification hand piece; a flexible small bore aspiration tubing configured to be in fluid communication with the aspiration path of the phacoemulsification hand piece, the small bore aspiration tubing having a nominal inner diameter smaller than about 1.27 mm (.050 inch) to reduce levels of occlusion surge within the surgical system, the inner diameter being substantially consistent through the length of the small bore aspiration tubing; and a peristaltic pump in communication with the small bore aspiration tubing operable to create a flow through the small bore aspiration tubing; wherein the small bore aspiration tubing comprises a flared portion on the inner diameter of at least one end, wherein when in an unloaded condition, the flared portion has an inner diameter larger than the nominal inner diameter of the small bore aspiration tubing; a connector (330, 332) is configured to receive at least a portion of the flared portion of the small bore aspiration tubing, the connector (330, 332) being sized to apply radial compression on the flared portion when the flared portion is inserted in the connector (330, 332) such that when the small bore aspiration tubing is disposed within the connector (330, 332), the inner diameter of the flared portion is about the same diameter as the nominal diameter of the small bore aspiration tubing.
