Abstract
A perforated trocar sleeve (20) is disclosed. The trocar sleeve has an elongate tubular body member (21) having a proximal end (22) and a spaced distal end (24). An inlet port (25) is defined in the proximal end of the body member, and an outlet port (26) is defined at the distal end thereof. The inlet and outlet ports, in association with the body member, define a continuous fluid flow conduit (28) within the body member. A plurality of openings (29) are defined in the exterior surface of the tubular body member and extend from the distal end of the body member at least partially toward the proximal end thereof. The fluid to be delivered into a body cavity is passed through these openings and dispersed through an arc extending radially about the axis of the body member. The openings may be spaced randomly or regularly along the length of the body member, and may be positioned within at least one recess (40,60) defined within the exterior surface of the body member. The openings defined in the body member may vary in size along the length of the body member.
