Claim 4

The invention of claim 1 wherein the balloon is constructed and arranged to be inflated to a maximum diameter of about 20-30 mm.

Claim 5

The invention of claim 3 wherein the wall of the probe member between the distal end and the balloon defines a plurality of holes through which fluid may pass from the through lumen to the surgical area and visa versa.

Claim 6

A surgical instrument for enabling a user to manipulate organs or parts thereof within the abdominal cavity and irrigate and/or aspirate the surgical area comprising: a) a tubular probe member having distal and proximal ends and a through lumen, the distal end being open, the tube wall adjacent the distal end defining a plurality of holes through which fluid may pass from the through lumen to the outside of the probe and visa versa; b) a handle member releasably secured to the proximal end of the probe member whereby the probe member may be disposed of after use, the handle member including a central passageway therein in fluid communication with the through lumen in the probe member, the handle member defining an irrigation port and an aspiration, each of the ports being connected to the central passageway, the irrigation port being adapted to be connected to a source of fluid under pressure for supplying irrigating fluid to the surgical area and the aspiration port being adapted to be connected to a vacuum source for aspirating fluid from the surgical area; d) the irrigation an aspiration ports including manually operable valves responsive to finger pressure applied laterally of the longitudinal axis of the handle whereby the user may manipulate the probe member and irrigate and/or aspirate the surgical area with one hand; e) an inflatable balloon secured to the exterior of the probe member adjacent to and on the proximal side of said holes so that the interior of the balloon is isolated from the through lumen; and f) the probe member including an auxiliary lumen extending along its length and in fluid communication with the interior of the balloon whereby fluid may be supplied to or removed from the interior of the balloon to inflate and deflate the same.

Claim 7

A surgical instrument for enabling a user to manipulate organs or parts thereof within the abdominal cavity and irrigate and/or aspirate the surgical area comprising: a) a tubular probe member having distal and proximal ends and a through lumen, the distal end being open, the tube wall adjacent the distal end defining a plurality of holes through which fluid may pass from the through lumen to the outside of the probe and visa versa; b) a handle member releasably secured to the proximal end of the probe member whereby the probe member may be disposed of after use, the handle member including a central passageway therein in fluid communication with the through lumen in the probe member, the handle member defining an irrigation port and an aspiration, each of the ports being connected to the central passageway, the irrigation port being adapted to be connected to a source of fluid under pressure for supplying irrigating fluid to the surgical area and the aspiration port being adapted to be connected to a vacuum source for aspirating fluid from the surgical area; d) the irrigation an aspiration ports including manually operable valves responsive to finger pressure applied laterally of the longitudinal axis of the handle whereby the user may manipulate the probe member and irrigate and/or aspirate the surgical area with one hand; e) an inflatable balloon secured to the exterior of the probe member adjacent to and on the proximal side of said holes so that the interior of the balloon is isolated from the through lumen; and f) the probe member including an auxiliary lumen extending along its length and in fluid communication with the interior of the balloon whereby fluid may be supplied to or removed from the interior of the balloon to inflate and deflate the same.

Claim 8

The invention of claim 5 wherein the diameter of the tubular member is within the range of 3 to 6 mm.

Claim 9

The invention of claim 6 wherein the balloon is provided with a roughened surface to aid the user in manipulating organs or parts thereof.

Claim 10

The invention of claim 5 wherein the probe member is formed of a carbon impregnated plastic material.

Claim 11

The invention of claim 5 wherein the balloon is constructed and arranged to be inflated to a diameter of about 20-30 mm.

Claim 12

The invention of claim 9 wherein the holes in the probe member extend along a distance of about 10-30 mm.

Claim 13

A surgical instrument for enabling a user to manipulate organs or parts thereof within the abdominal cavity and irrigate and/or aspirate the surgical area comprising: a) a tubular probe member having distal and proximal ends and a through lumen, the distal end being open, the tube wall adjacent the distal end defining a plurality of holes through which fluid may pass from the through lumen to the outside of the probe and visa versa; b) a handle member having a longitudinal axis and being secured to the proximal end of the probe member and including a central passageway therein in fluid communication with the through lumen whereby fluid may be supplied or removed from the body cavity or organ in which the distal end of the probe is inserted, the handle member further defining an irrigation and an aspiration port connected to the central passageway, the irrigation port being adapted to be connected to a source of fluid under pressure for supplying irrigating fluid to the surgical area, the aspiration port being adapted to be connected to a vacuum source for aspirating fluid from the surgical area, each port including a manually operable valve responsive to finger pressure applied laterally of the longitudinal axis of the handle whereby the user may manipulate the probe member and irrigate and/or aspirate the surgical area with one hand; c) an inflatable balloon secured to the exterior of the probe member adjacent to and proximal of said holes so that the interior of the balloon is isolated from the through lumen; and d) the probe member including an auxiliary lumen extending along its length and in fluid communication with the interior of the balloon whereby fluid may be supplied to or removed from the interior of the balloon to inflate and deflate the same.

Claim 14

A surgical instrument for enabling a user to manipulate organs or parts thereof within the abdominal cavity and irrigate and/or aspirate the surgical area comprising: a) a tubular probe member having distal and proximal ends and a through lumen, the distal end being open, the tube wall adjacent the distal end defining a plurality of holes through which fluid may pass from the through lumen to the outside of the probe and visa versa; b) a handle member having a longitudinal axis and being secured to the proximal end of the probe member and including a central passageway therein in fluid communication with the through lumen whereby fluid may be supplied or removed from the body cavity or organ in which the distal end of the probe is inserted, the handle member further defining an irrigation and an aspiration port connected to the central passageway, the irrigation port being adapted to be connected to a source of fluid under pressure for supplying irrigating fluid to the surgical area, the aspiration port being adapted to be connected to a vacuum source for aspirating fluid from the surgical area, each port including a manually operable valve responsive to finger pressure applied laterally of the longitudinal axis of the handle whereby the user may manipulate the probe member and irrigate and/or aspirate the surgical area with one hand; c) an inflatable balloon secured to the exterior of the probe member adjacent to and proximal of said holes so that the interior of the balloon is isolated from the through lumen; and d) the probe member including an auxiliary lumen extending along its length and in fluid communication with the interior of the balloon whereby fluid may be supplied to or removed from the interior of the balloon to inflate and deflate the same.
