  • Surgical suction device having a perforated sleeve
    Patent number: 4767404
    Abstract: A perforate suction tip for removal of surgical debris with reduced clogging and with minimum trauma to tissue is disclosed. Suction ports are arranged on the tip so that suction ports which remain unblocked when surgical debris lodges in other suction ports operate as a vacuum modulator facilitating the removal of the blockage. Further, the likelihood of blocking every suction port, thereby aspirating and damaging tissue, is greatly reduced.
