Abstract
An endoscopic aspiration instrument suitable for use with a trocar sheath in laparoscopic surgical procedures is disclosed for aspirating fluid from an ovarian cyst without leakage of the fluid into the peritoneal cavity. The endoscopic instrument comprises a elongated suction tube member having a needle guide positioned within the passageway thereof. The suction tube and needle guide are connected at the proximal ends thereof with the use of a three access port connector. The first access port connects to the proximal end of the suction tube. The proximal end of the needle guide tube is extended through the first port and connected to the second port of the T-type connector. An aspiration needle is inserted through a sealing cap positioned over the second access port and into the passageway of the needle guide tube. A centering device comprising a sleeve and a plurality of radially extending arms is positioned about the distal end of the needle guide tube for centering the needle guide tube within the passageway of the suction tube. The centering device is also located a predetermined distance from the distal end of the suction tube for preventing the ovarian cyst from being drawn too far into the suction tube. The connector also includes a third side port for connection to suction equipment for providing a vacuum in the suction tube to engage the ovarian cyst.
