Abstract

Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes an elongate hollow tube having a proximal end that is configured to be positioned adjacent to a tissue surface and a distal end configured to extend through a body wall into a body cavity. The proximal end of the device can be can be configured to allow the proximal-most portion of the surgical access device to rest flush or substantially flush against a tissue surface of a patient when the device is inserted into the patient. In some embodiments, the elongate hollow tube can have a non-circular cross-section.

Description

technical field [0001] The present invention relates to methods and devices for performing surgical procedures, and more particularly to methods and devices for accessing body cavities. Background technique [0002] Laparoscopic surgery gained popularity in the late 1980s when the advantages of laparoscopic cholecystectomy over conventional (open) surgery became apparent. The recognized advantages of laparoscopic procedures are shortened postoperative recovery time, significantly reduced postoperative pain and wound infection, and improved cosmetic outcomes, mainly due to the ability of laparoscopic surgeons to operate through smaller incisions in the body cavity wall. [0003] Laparoscopic procedures generally involve placing the CO 2 Gas was injected into the abdominal cavity to bring the pressure to about 15mmHg. A hole is made in the abdominal wall, and then a straight cannula or trocar cannula with a diameter of 5-10 mm is inserted into the abdominal cavity. A laparo...
