Caps for sealing a cannula assembly |
摘要 |
A cannula cap for sealing a cannula assembly during insufflatory surgery, the cap comprising an endwall made of elastomeric material and a sidewall. The cap is sized and configured to fit to the instrument entrance of a cannula in a relative gas-tight relationship. The endwall of the cap may be apertured to permit entry and exit of a trocar or other surgical instrument without significant interruption of the seal. Another embodiment provides an adaptor cap also comprising an endwall made of an elastomeric material and a sidewall, the adaptor cap arranged to be fitted to the cannula cap for temporary insertion and withdrawal of instruments of relatively small diameter without removal of the cannula cap.
