Abstract (en)
[origin: WO0069495A1] A surgical visualization and moisturizing device (10) providing improved visualization and moisturizing of a surgical site such as an anastomosis. The device (10) of the present invention is provided with a plurality of small flexible lumens (56) extending through and terminating distal of a gas flow port (44) to thoroughly mix and moisture the gas flow (60) with a saline solution. Each of the plurality of flexible lumens (56), preferably forming a ribbon (50), are separated from one another slightly at the distal tip (40) to permit vibration due to the gas flow (60) exiting about and past each of the saline lumens (56). This spacing further facilitates uniform moisturizing of the gas flow (60). The distal ends of the saline lumens (56) extend beyond the tip (40) of the device (10) such that the pressure of the gas flow (60) approaches atmospheric pressure, whereby gas flow (60) will not go against the head pressure of the saline bag. This eliminates the need for a pressure cuff on the saline bag. The present invention further minimizes dripping at the distal tip (40), further improving visualization of an anastomosis site for the surgeon.
