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;
a valve disposed on the housing and fluidly coupled with a first lumen of the plurality of lumens; and
a tip member disposed at a distal end of the tubular member, the tip member including a first port that is aligned and fluidly coupled with the first lumen of the plurality of lumens, the first port configured to direct a fluid towards a predetermined location.
2 . The surgical access device of claim 1 , wherein the tubular member includes an inner tube and an outer tube defining an annular chamber therebetween, the annular chamber fluidly coupled to the valve, the first lumen of the plurality of lumens disposed within the annular chamber.
3 . The surgical access device of claim 3 , wherein the annular chamber includes the second lumen of the plurality of lumens extending therethrough, the second lumen of the plurality of lumens fluidly coupled to a second port located in the tip member, the second port configured to direct a fluid towards the predetermined location.
4 . The surgical access device of claim 1 , wherein the inner tubular member defines a third lumen of the plurality of lumens extending therethrough.
5 . The surgical access device of claim 3 , wherein the first and second lumens of the plurality of lumens are radially spaced apart.
6 . The surgical access device of claim 3 , wherein the predetermined location lies along a central longitudinal axis of the tubular member.
7 . The surgical access device of claim 2 , wherein the valve fluidly couples a source of fluid to the first and second lumens of the plurality of lumens.
8 . The surgical access device of claim 5 , wherein the first port is offset from the second port by 180°.
9 . The surgical access device of claim 8 , wherein each of the first and second ports has a spray pattern that covers 180° of the predetermined location.
10 . The surgical access device of claim 5 , wherein the first port and the second port are radially offset in a range between about 60° and about 120°.
11 . The surgical access device of claim 4 , wherein the channel is configured to receive a viewing instrument therethrough.
12 . The surgical access device of claim 3 , wherein the surgical access device is insertable through an opening in tissue.
13 . A method for cleaning a viewing instrument comprising:
moving a lens of a viewing instrument towards a target area defined in a channel of a tubular member, the tubular member including an inner tube disposed in an outer tube defining an annular chamber therebetween; and
dispensing a cleaning fluid from a first port towards the target area, the first port located on a tip member, the tip member located at a distal end of the tubular member, the first port fluidly coupled to a first lumen of a plurality of lumens that is disposed in the annular chamber, the first lumen of the plurality of lumens fluidly coupled to a valve for controlling flow of the cleaning fluid.
14 . The method of claim 13 , wherein dispensing the cleaning fluid includes dispensing the cleaning fluid from a second port towards the target area, the second port located on the tip member and fluidly coupled to a second lumen of the plurality of lumens that is disposed in the annular chamber, the second lumen of the plurality of lumens fluidly coupled to the valve for controlling flow of the cleaning fluid.
15 . The method of claim 13 , wherein moving the optical portion includes moving the optical portion into a third lumen of the plurality of lumens defined by the inner tube.
16 . The method of claim 13 , further including:
positioning the tubular member through tissue of a patient, the tubular member extending from a housing with a seal member.
17 . The method of claim 13 , further including repositioning the lens of the viewing instrument along a longitudinal axis of the tubular member such that the lens moves into and out of the predetermined region.
18 . The method of claim 17 , further including viewing an image on a monitor coupled to the viewing instrument during repositioning of the lens.
