ABSTRACT:
A spongestick for endoscopic procedures including a hollow stem of substantially cylindrical cross-section with a longitudinal groove along its outer surface and having a handle at one end and a balloon receptor portion at the other end. The stem is surrounded by a retractable sheath having a handle at the end adjacent the stem handle. A balloon system is included having a Leur lock tip at its upper end for coupling to inflation means and an elongated tube portion which extends within the longitudinal groove in the stem to a tubular balloon which fits over the receptor portion. Circumferential grooves are provided on the upper and lower sections of the receptor portion to accommodate rubber bands which secure a tubular gauze member over the balloon. The gauze member is expanded by inflation of the balloon. The hollow interior of the stem provides a passage for endoscopic instruments such as forceps, dissectors, etc.
