  • Surgical aspiration device
    Patent number: 5024615
    Abstract: Surgical aspiration device for use in surgical operations, whereby the aspiration device is intended for use in atraumatic aspiration, tissue aspiration and disection. The surgical aspiration device comprises a handle with an inner tube and an outer tube which extend from the handle and which are arranged concentrically, with an interstice formed between them. Adjacent to the handle is an inlet opening which allows air into said interstice. When a vacuum is applied to the inner tube for aspiration, air passes into the interstice and into the inner tube, whereby the aspirated liquid column is broken and atraumatic aspiration can take place.
