Until suction became available in the 1930s, maintenance of a clear airway during oral and nasal surgery relied on posturing of the patient, mopping with sponges or the temporary placement of swabs or throat guards. Removal of surgical debris such as polyps, blood clots or foreign bodies could only be effected by the finger or devices such as probangs. The Probang is inserted blind (perhaps guided by a finger), the main shaft can then be held in the left hand whilst the right hand withdraws the inner tube. This results in a fanning out of the linear strands which are visible proximal to the tip. Held in this position the instrument is withdrawn and is supposed to scoop out the offending mass.
