Abstract

A hollow, T-shaped body is connected to an extroducer rod by a flexible drain tube. The extroducer rod is longer than a human female vagina, sufficiently stiff to be passed therethrough when the vagina is in a collapsed state, and has a smooth rounded end to facilitate insertion through the vaginal cuff and passage through the vagina during an abdominal hysterectomy. The extroducer rod is also larger in diameter than a Foley catheter which is used to drain the bladder, and formed with external flutes which make it easily distinguishable from the catheter by feel. The T-shaped body has a leg which is connected to the drain tube, and two perpendicular arms. Drain holes are formed through the arms which open in a direction away from the leg. The innermost drain hole of each arm is cut away to a sufficient depth that the arms can collapse to positions parallel to the leg and drain tube to facilitate withdrawal of the body through the vagina. Notches having smooth, rounded walls are formed at desired spacings in the arms to facilitate trimming the arms to fit the patient'"'"'s anatomy. The rounded walls of the notches and the location of the drain holes which face inwardly toward each other in the collapsed position of the arms prevents irritation of the vaginal wall by sharp edges during withdrawal.

Claims

1. An extroducer rod for retrograde introduction of a hysterectomy drain appliance, said rod being solid, unperforated and being sufficiently stiff as to be easily pushed through a female human vagina, being longer than a human female vagina, having a smooth, closed, rounded first leading end, and having an opposite end formed with a drain tube connector, at least a portion of said rod extending from the rounded end having longitudinally shaped side walls with longitudinal ridges of sufficient height to permit ready identification of the exterior of the rod by feel by a human hand.

2. An extroducer rod as in claim 1, in which the rounded end is sufficiently larger in diameter than a Foley catheter as to be distinguishable therefrom by feel.

3. An extroducer rod as in claim 1, in which the rounded end is approximately 0.375 inches in diameter.

4. An extroducer rod as in claim 1, in which the external ridges comprise longitudinal flutes.

5. An extroducer rod as in claim 1, which is tapered inwardly from said ends to a central portion thereof.

6. An extroducer rod as in claim 1, which is approximately 14 inches long.
