摘要：
A surgical suction device that uses positive pressure gas is shown and described. The surgical suction device includes an air amplifier. The air amplifier includes a structure defining a generally cylindrical cavity having a first opening at a first end and a second opening at a second end. The cylindrical cavity is defined by an inner wall of the cavity. The air amplifier includes an annular opening in the inner wall near the first end. The annular opening defines a jet opening adapted to allow a pressurized gas to flow out of the annular opening such that a low pressure region is produced at the first end and an amplified flow is produced at the second end. The annular opening is further configured such that the pressurized gas enters the cavity at an angle with respect to the inner wall of the cavity that is towards the second end.
