TROCAR ASSEMBLY FOR DRAINING FLUIDS FROM A BODY PART ABSTRACT This surgical trocar assembly has the needle of a stylet removably disposed inside a first cannula which is inside a second cannula in a concentric array. The needle has a sharp point to pierce a body part to be drained of fluids. A first fitting on the first cannula has a first nipple to engage an aspiration tube when the needle is removed. The fitting has a tenon to engage in a tubular member of a Y-shaped joint structure. The tubular member has a lateral second nipple to engage an end of a wash fluid feed tube. A second fitting on the second cannula engages on the tubular member so that wash water passes through the tubular member between the first and second cannulas. The first cannula has a tapered sharp open end to enter the body part for aspirating fluids therefrom. The second cannula has a tapered end to engage the outside of the first cannula near its tapered open end, and further has lateral openings to discharge wash fluid from the second cannula to the body part.
