The present invention provides a coupling device for attaching a sleeve ( 40 ) to a surgical aspirator tip ( 10 ) that allows airflow between the external environment and the interior of the sleeve ( 40 ). The coupling device includes a male member ( 26 ) attached to the tip ( 10 ) and a female member ( 42 ) formed in the proximal end of the sleeve ( 40 ). The male member ( 26 ) includes at least one longitudinal groove ( 100 ). When the male member ( 26 ) is received into the female member ( 42 ), at least one venting channel ( 80 ) is defined between at least one longitudinal groove of the male member ( 26 ) and the inner surface of the female member ( 42 ). Venting channel ( 80 ) permits airflow between the external environment and the interior of the sleeve ( 40 ). |
