Definitions

  • the present invention relates to aspirating devices. Particularly, the invention relates to a method for the production of such devices for use in surgery.
  • suction devices are often used. These are effective for non-viscous fluids such as non-clotted blood. However, the effectiveness is diminished when more viscous fluids are involved, such as contents of cysts, thick secretions, blood clots, viscid forms of pus and other hard pathologic materials. Suction activity is insufficient for the evacuation of such solid and semi-solid types of refuse, rather direct mechanical intervention is needed.
