Patent

CA 2625734

The invention relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the "doming" phenomenon produced by insufflation of a patient's abdomen is reduced.

La présente invention concerne un dispositif de laparoscopie à accès manuel comportant un capuchon de gel, un élément de retenue, un manchon et un anneau de retenue. Ledit capuchon comprend du gel qui est lié à un capuchon. Le capuchon comprend une paroi cylindrique interne à laquelle le gel est lié, formant ainsi une zone d~étanchéité entre le dispositif et la plaie dans une paroi corporelle. En fixant le gel à la paroi cylindrique interne, l~épaisseur du gel et du capuchon correspondant est réduite au même titre que l~empreinte globale du dispositif. L~épaisseur de gel étant réduite et pouvant sensiblement affleurer, le phénomène de « dôme » produit par le gonflement de l~abdomen d~un patient est réduit.
