Abstract
Abstract In abdominal operations, particularly gyneacological abdominal operations, gauze-like material is often used in practice to hold organs such as intestines away from the operative area. This gauze-like material must in many cases be replaced during an operation and also lacks the desired stiffness to hold the intestines in particular in place in all cases. The present invention provides a cushion-like member for inserting into a relatively large body cavity, as formed during abdominal/pelvis surgery, and for restraining one or more body organs (for instance the intestines) and/or for absorbing blood and/or wound fluid, wherein the cushion-like member consists substantially of synthetic, absorbent material and has a outer contour of such shape that it is layable along and or beyond an edge of said body cavity.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
A flexible cushion member for insertion into a body cavity formed during surgery for restraining at least one body organ, said member formed of an absorbent material for absorbing blood and other fluids and having a preformed outer contour adapted for use in said body cavity, wherein a portion of said outer contour is convex, and a portion of said cushion member which is opposite said convex portion is concave in shape and defines a recess therein for eliminating pressure on retro-peritoneal vessels in said body cavity during use of said flexible cushion member.
Claim 2
Dependent Claim
94 words
A flexible cushion member for insertion into a body cavity formed during surgery for restraining at least one body organ, said member formed of an absorbent material for absorbing blood and other fluids and having a preformed outer contour adapted for use in said body cavity, wherein a portion of said outer contour is convex, and a portion of said cushion member which is opposite said convex portion is concave in shape and defines a recess therein for eliminating pressure on retro-peritoneal vessels in said body cavity during use of said flexible cushion member.
Claim 3
Dependent Claim
25 words
The cushion member as claimed in claim 1, wherein said absorbent material is polyvinylalcohol hydro foam, and said cushion member is sterilized with gamma radiation.
Claim 4
Dependent Claim
43 words
The cushion member as claimed in claim 1 wherein said cushion member has a thickness of approximately 23 mm, a height of approximately 120 mm, and a length of approximately 234 mm, and wherein said recess has a breadth of approximately 108 mm.
Claim 5
Dependent Claim
40 words
The cushion member as claimed in claim 1, wherein said cushion member has a thickness, a height, a length which is approximately 95% larger than said height, and a breadth of said recess which is approximately 90% of said height.
Claim 6
Dependent Claim
15 words
The cushion member as claimed in claim 4 wherein said thickness is approximately 23 mm.
Claim 7
Dependent Claim
96 words
A flexible, sterilized intestinal retraction pad for insertion into a patient's abdominal cavity during surgical operations to hold intestines of said patient out of an operating cavity, said pad being formed of a synthetic, absorbent material for absorbing blood and other fluids, said pad having a preformed outer contour, wherein a portion of said outer contour contacts said intestines to hold said intestines out of said operating cavity and is convexly shaped; and a recess means formed in said pad for eliminating pressure on retro-peritoneal vessels of said patient during use of said intestinal retraction pad.
Claim 8
Dependent Claim
96 words
A flexible, sterilized intestinal retraction pad for insertion into a patient's abdominal cavity during surgical operations to hold intestines of said patient out of an operating cavity, said pad being formed of a synthetic, absorbent material for absorbing blood and other fluids, said pad having a preformed outer contour, wherein a portion of said outer contour contacts said intestines to hold said intestines out of said operating cavity and is convexly shaped; and a recess means formed in said pad for eliminating pressure on retro-peritoneal vessels of said patient during use of said intestinal retraction pad.
Claim 9
Dependent Claim
25 words
The pad of claim 6 wherein said recess means is formed on a side of said pad which is opposite to said convexly shaped portion.
Claim 10
Dependent Claim
19 words
The pad of claim 7 wherein said recess means is defined by a concavely shaped portion of said pad.
Claim 11
Dependent Claim
14 words
The pad of claim 8 wherein said pad is formed of polyvinylalcohol hydro foam.
Claim 12
Dependent Claim
37 words
The pad of claim 9 wherein said pad has a thickness, a height, a length which is approximately 95% larger than said height, and a breadth of said recess means which is approximately 90% of said height.
Claim 13
Dependent Claim

The pad of claim 9 wherein said pad has a thickness of approximately 23 mm, a height of approximately 120 mm, a length of approximately 23 mm, and a breadth of said recess means of approximately 108 mm.
Claim 14
Independent Claim
133 words
A method of intestinal retraction during surgical procedures comprising the insertion of a flexible, sterilized retraction pad into a patient's abdominal cavity during surgical operations to hold intestines of said patient out of an operating cavity, said pad being formed of a synthetic, absorbent material for absorbing blood and other fluids, said pad having an outer contour, wherein a portion of said outer contour contacts said intestines to hold said intestines out of said operating cavity and is convexly shaped; and a recess means formed in said pad for eliminating pressure on retro-peritoneal vessels of said patient during use of said intestinal retraction pad wherein said convexly shaped portion is positioned facing away from said operation cavity and said recess means is positioned such that no pressure is exerted on said retro-peritoneal vessels.
Claim 15
Independent Claim
133 words
A method of intestinal retraction during surgical procedures comprising the insertion of a flexible, sterilized retraction pad into a patient's abdominal cavity during surgical operations to hold intestines of said patient out of an operating cavity, said pad being formed of a synthetic, absorbent material for absorbing blood and other fluids, said pad having an outer contour, wherein a portion of said outer contour contacts said intestines to hold said intestines out of said operating cavity and is convexly shaped; and a recess means formed in said pad for eliminating pressure on retro-peritoneal vessels of said patient during use of said intestinal retraction pad wherein said convexly shaped portion is positioned facing away from said operation cavity and said recess means is positioned such that no pressure is exerted on said retro-peritoneal vessels.
Claim 16
Dependent Claim
45 words
The method of claim 12 further comprising the preliminary steps of packaging the pad prior to use and moistening said pad prior to packaging; said package comprising a peel package; and sterilizing said package and pad by gamma radiation after said package has been sealed.
Claim 17
Dependent Claim
16 words
The method of claim 12 wherein said pad is slightly folded during insertion for proper positioning.
