Abstract

A bowel retractor device comprising a bendable collar, a flexible planar film, and at least one preformed opening defined in the flexible planar film is disclosed. The at least one preformed opening is configured to retainingly support at least one section of bowel. The at least one preformed opening comprises an open center portion defining a hole in the flexible planar film and a plurality of radially-extending slots extending from an outer perimeter of the hole. Each radially-extending slot comprises a slot width that is different from a diametrical width of the hole to form a plurality of gripping portions extending inward toward the open center portion. The gripping portions are formed for gripping the at least one section of bowel to retainingly support the at least one section of bowel inserted through the open center portion.

Claims

1. A bowel retractor device, comprising:

a bendable collar defining a central area, said bendable collar being selectively bendable between a planar configuration and non-planar configurations and be self-retained in such non-planar configurations;

a flexible planar film coextensive with said central area and including a perimeter attached to said bendable collar; and

at least one preformed opening defined in said flexible planar film, wherein said at least one preformed opening is smaller than said central area such that said at least one preformed opening is completely bounded by portions of said flexible planar film, wherein said at least one preformed opening is configured to retainingly support at least one section of bowel therethrough, and wherein said at least one preformed opening comprises;

an open center portion defining a hole in said flexible planar film; and

a plurality of radially-extending slots extending from an outer perimeter of said hole, each said radially-extending slot comprising a slot width that is different from a diametrical width of said hole to form a plurality of gripping portions extending inward toward said open center portion, wherein said gripping portions are formed for gripping said at least one section of bowel to retainingly support said at least one section of bowel inserted through said open center portion.

2. The bowel retractor device of claim 1, wherein said bendable collar comprises a metal wire embedded around the perimeter of said flexible planar film.

3. The bowel retractor device of claim 1, wherein said diametrical width is larger than said slot width.

4. The bowel retractor device of claim 1, wherein said plurality of radially-extending slots comprises at least five radially-extending slots.

5. The bowel retractor device of claim 1, wherein each said radially-extending slot opens into said open center portion and comprises an end radially displaced from said open center portion, and wherein a first portion of each said radially-extending slot opening into said open center portion comprises a first slot width and wherein a second portion of each said radially-extending slot is radially displaced from said first portion and comprises a second slot width that differs from said first slot width.

6. The bowel retractor device of claim 5, wherein said end of each said radially-extending slot comprises a rounded profile.

7. The bowel retractor device of claim 1, wherein said flexible planar film comprises a film having a thickness ranging from 0.020 inches to 0.120 inches.

8. The bowel retractor device of claim 7, wherein said flexible planar film comprises a silicone material.

9. The bowel retractor device of claim 7, wherein said flexible planar film comprises a neoprene material.
