Abstract
A disposable unitary drape particularly suited for use in performing transurethral surgery of the bladder and prostate, and similar operations. A thin flexible finger cot projects from the body of the drape, the cot having a bulbous distal end portion and an elongated neck portion of reversed taper and reduced wall thickness. An annular retention rib projects outwardly from the cot at the juncture of the neck and end portions and, in one embodiment, the wall thickness of the neck portion is even further reduced in an arcuate intermediate section to increase tactile sensitivity in that zone for the surgeon. The cot may be supplied in longitudinally collapsed form. Because of its configuration and construction, the cot tends to be self-retaining in use.
