    摘要: A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.
