  • Patent number: 4022218
    Abstract: A surgical suction tube for removing surgical debris from within a sterile surgical operative field that is highly resistant to clogging. A tapering transparent plastic tube forms a suction tip having a plurality of apertures at its small end and a tapered opening at its large end and is inserted in the surgical wound to be cleaned. A turbulence chamber having a generally circular transverse cross section, a bulbous central portion tapering to two smaller ends has one end inserted into the large tapered end of the suction tip and the other end connected to flexible plastic tubing that leads from the sterile field to a source of suction and debris-collecting elements. The suction appearing at the suction tip apertures draws debris into the turbulence chamber in which the air turbulence generated therein maintains particulate matter in the debris in a loose state, preventing frequent clogging.
