Cotton/rayon tipped applicators

Abstract

Applicators conformed of a cotton-wool or rayon tip on a thin wooden stick are used for dipstick technique cryosurgery. The tip is submerged in LN contained in a cup or flask and transferred to a lesion. Significant loss of cooling is lost in the process, making it less efficient than spray. Sticks, cotton-wool and rayon can be bought separately to improvise large tip applicators.
