Multi lumen access device
A surgical access device includes a housing, a tubular member extending from the housing, a valve disposed on the housing, and a tip member at a distal end of the tubular member. The housing includes a seal and the tubular member includes a plurality of lumens extending therethrough. The valve is fluidly coupled with a first lumen of the plurality of lumens and the tip member includes a first port that is aligned and fluidly coupled with the first lumen of the plurality of lumens. The first port is configured to direct a fluid towards a predetermined location.
1. A surgical access device comprising:
a housing including a seal;
a tubular member extending from the housing, the tubular member including a plurality of lumens extending therethrough and inner and outer tubes that define an annular chamber therebetween, the plurality of lumens disposed within the annular chamber and radially spaced apart;
a valve disposed on the housing and fluidly coupled with the plurality of lumens; and
a tip member disposed at a distal end of the tubular member, the tip member including first and second ports aligned and fluidly coupled with respective first and second lumens of the plurality of lumens, the first port including a cavity having a tapered configuration extending between a proximal region and a distal region, the proximal region having a first width and the distal region having a second width less than the first width and configured to direct fluid flow towards a central longitudinal axis of the tubular member, the second port including a pocket extending between proximal and distal regions thereof, the pocket having a uniform width, the tip member having an open distal end configured to allow passage of an endoscope therethrough.
2. The surgical access device of claim 1 , wherein a velocity of a fluid exiting the first port is greater than a velocity of a fluid exiting the second port.
3. The surgical access device of claim 1 , wherein a first duct of the first port has a length equal to a length of a second duct of the second port.
4. The surgical access device of claim 1 , wherein the tapered configuration of the cavity increases a velocity of a fluid passing from the proximal region of the first port to the distal region of the first port.
5. The surgical access device of claim 4 , wherein a portion of the distal region of the first port is angled towards the central longitudinal axis of the tubular member such that fluid flow through the first port is directed towards the central longitudinal axis of the tubular member.
6. The surgical access device of claim 1 , wherein the first port is offset from the second port by 180°.
7. The surgical access device of claim 1 , wherein the first port and the second port are radially offset in a range between about 60° and about 120°.
8. The surgical access device of claim 1 , further including a third port aligned and fluidly coupled to a third lumen of the plurality of lumens, the third port having a cavity with a tapered configuration comparable to the tapered configuration of the first port.
9. The surgical access device of claim 8 , wherein the first port is spaced a first distance from the central longitudinal axis of the tubular member and the third port is spaced a third distance from the central longitudinal axis of the tubular member, the first distance different from the third distance.
10. The surgical access device of claim 1 , wherein the tubular member defines a channel extending therethrough, the channel configured to receive a viewing instrument therethrough.
