Three-fan-blade type auxiliary funnel for nidus ultrasonic treatment apparatus

The utility model provides a three-fan-blade type auxiliary funnel for a nidus ultrasonic treatment apparatus and belongs to auxiliary instruments used for ultrasonic treatment in medical instruments. The three-fan-blade type auxiliary funnel comprises a barrel-type funnel body and is characterized in that a split-type funnel bottom is disposed at the bottom of the barrel-type funnel body. The split-type funnel bottom is a hollow disk which is formed by six fan-shaped pieces in split type. A metal disk is inlaid in the hollow round hole of the hollow disk. The six fan-shaped pieces are composed of three metal pieces and three rubber pieces which are alternately arranged at intervals. The three-fan-blade type auxiliary funnel overcomes the defect that in the prior art, peripheral scattering focal areas around a center area free of disease are inconvenient to treat by using the ultrasonic treatment apparatus, and simultaneously solves the problem that an existing auxiliary funnel can easily leak water.
