Abstract

An endodissector for dissecting, wiping and cleaning tissues during laparoscopic or conventional surgery comprises an elongated or tubular instrument having a one piece molded, solid or tubular plastic mesh tip at one end and an elongated body comprising a handle at the other end. The tip is mounted on a frame and includes a threaded base extending downwardly to engage a threaded receptacle in the elongated body. The frame and mesh tip may include a straight central lumen for the insertion and use of laparoscopic instruments. Optionally, the frame may include a side port coupled to the lumen for irrigation purposes.
