Abstract

A portable surgical aspirator (10) for use in removing body fat and fluids by drawing same under vacuum through a cannula (52) that is inserted beneath a person's skin performing a liposuction surgical procedure. The aspirator is maintained in a single housing (11) that is caster mounted for ease of movement and includes dual oilless vacuum pumps (15) mounted to opposite ends of an electric motor (14) that can be operated from a manual switch (27) located on the housing or a remote foot switch (65). Pump (15) operation provides, through a single vacuum (18) port, nearly one atmosphere of vacuum within three seconds. The vacuum port (18) is connected through hoses to vacuum bottles (34) and (38) that are for collecting fat and body fluids, passed through tubing from the cannula. The vacuum bottles are maintained in a bottle caddy (56) that is arranged for releasable attachment to the aspirator housing. The aspirator includes a handle (22) that, with the handle ends (23a) and (23 b) secured to the aspirator housing is centrally gripped by an operator for carrying the device, or, with one handle end released, and the handle (22) pivoted around its other end, the released handle end can receive an operator's hand for manually pulling the device rolling on its casters.
