Abstract

Bowel retractor devices. In various forms, the bowel retractor devices are configurable from a collapsed position wherein the retractor may be inserted through a trocar cannula or other opening in a patient'"'"'s body to a second expanded position wherein at least a portion of the patient'"'"'s bowel may be advantageously supported in a desired position.

Claims

1. A bowel retractor device comprising:

a flexible outer collar formed from a substantially flexible planar film material including a central opening therethrough, said film material further including a plurality of outwardly protruding tabs that are radially spaced around said central opening and wherein each said tab has at least one opening therethrough, said flexible outer collar being configurable from a first collapsed position wherein said flexible outer collar is configured to be fully passed through an opening in a patient'"'"'s body and a second expanded position wherein a portion of the patient'"'"'s bowel may be pulled through the central opening in a desired orientation; and

a flexible member radially woven through the tabs such that the flexible member extends around the central opening and being separately cinchable relative thereto.

2. The bowel refractor of claim 1 wherein said flexible member comprises a flexible cable.

3. A bowel refractor device comprising a flexible annular ring defining a central area;

and

a plurality of transversely overlapping interwoven members extending across said central area, each said interwoven member having two ends non-removably affixed to said flexible annular ring, said interwoven members having a weave tightness that permits at least one portion of a patient'"'"'s bowel to be pulled between at least some adjacent said interwoven members and retained therebetween without injuring the at least one bowel portion and wherein the retractor device is configurable from a first collapsed position wherein said annular ring is configured to be fully passed through an opening in a patient'"'"'s body as a unit and a second expanded position.

4. The bowel retractor device of claim 3 wherein said plurality of interwoven flexible members comprises a plurality of interwoven flexible ribbon members.

5. The bowel retractor device of claim 3 wherein said plurality of interwoven flexible members comprises:

a first layer of interwoven members; and

a second layer of interwoven members spaced from said first layer of interwoven members.

6. The bowel refractor device of claim 5 wherein each said interwoven member has a substantially circular cross-sectional shape.
