Medical laser device

Image Number 3 for United States Patent #4674497.

A medical laser device includes a device body and a laser probe connected to the body. In the device body are arranged a laser source for emitting laser beams and an air pump. The laser probe has an outer tube, a laser guide extending through the tube, and an air supply passage defined between the inner surface of the tube and laser guide. The laser beams emitted from the laser source are guided through the laser guide and ejected from the distal end of the laser guide. A drying unit is connected to the discharge side of the pump. Air streams are supplied from the pump to the air supply passage after being dried by the drying unit, and then ejected from the air supply passage toward the distal end of the laser guide.
