Weil Blakesley straight cup forceps

This single action forceps is a common instrument used in functional endoscopic sinus surgery. It is used to remove bulla ethmoidalis and other ethmoidal air cells. It can also be used to remove small bone chips from the nasal cavity during endoscopic sinus surgical procedures.

It can also be used to remove polypi from nose.

All forces used in endoscopic sinus surgery have a distal hinge and the blades only open at the tip of the instrument. This ensures that the lever advantage and the strength of the instrument resides at its tip. It also limits the opening capacity of the instrument distally thus making it accessible at the narrow spaces within the nasal cavity.

The advantage of single action forceps is that it is more stable and stronger than double action forceps. The major disadvantage of single action forceps is that the space between the blades of forceps is rather limited. It has an eye at its upper jaw to permit proper visualization of tissue.
