In a case of suspected pelvic abscess, I introduced an aspirator needle for diagnostic purposes, and finding pus, I incised the vaginal mucous membrane at the base of the needle with the intention of conducting along the round needle a director, and in the groove of this instrument a narrow scissors with the view of so dilating the opening that I could insert a drainage tube, irrigate and secure drainage.
