Surgical diaphragm for maintaining the pneumoperitoneum during a laparoscopic procedure

摘要

A surgical diaphragm for use in laparoscopic gynecological surgery is illustrated and described. Proximal and distal tubes extend from the diaphragm with the end of the proximal tube being accessible to the surgeon. The diaphragm functions to maintain the pneumoperitoneum during laparoscopic surgery when a colpotomy is required. The proximal tube may be sealed in such a way as to permit fluid egress and ingress to the surgical site through the colpotomy, and also to permit surgical tools to be inserted through the tubes.
