Abstract

Embodiments of a circumferential retractor having an attached supporting, manipulating or positioning tool are described. The retractor optionally includes a sealing member associated with an external member of the retractor and an external support structure that may be used with the retractor and positioning tool as needed.

Claims

1. A surgical retractor, comprising:

an external support member;

an internal support member;

a connecting member having a distal end, a proximal end, and a tissue contacting surface, the proximal end of the connecting member connected to the external support member and the distal end of the connecting member connected to the internal support member;

a first positioning element comprising a first holding portion and a first connecting portion, wherein the first connecting portion is releasably connected to the external support member; and

a second positioning element, comprising a second holding portion and a second connecting portion, wherein the second connecting portion is releasably connected to the first connecting portion, wherein the first connecting portion defines a generally semicircular configuration adapted to slide under and engage the external support member, and wherein the first connecting portion further comprising a first engaging feature and the second connecting portion further comprising a second engaging feature, wherein the first engaging feature connects to the second engaging feature when the second connecting portion is disposed over the external support structure to thereby capture the external support structure between the first and second connecting portions.

2. The surgical retractor of claim 1, further comprising a support structure, the support structure having a base and a pivot point, wherein the base is configured to attach to a surgical table and the pivot point is configured to attach to the holding portion of at least one of the positioning elements.

3. The surgical retractor of claim 1, further comprising a first support structure and a second support structure, each support structure having a base and a pivot point, wherein the bases are configured to attach to a surgical table, the pivot point of the first support structure is attached to the first positioning element and the pivot point of the second support structure is attached to the second positioning element.

4. The surgical retractor of claim 1, wherein the internal support member comprises an inflatable toroid, the inflatable toroid being connected to a transfer conduit configured to interact with a gas or fluid supply.

5. The surgical retractor of claim 1, wherein the internal support member comprises a memory foam, the internal support member configured to be deformed for insertion through an incision, returning to a predetermined shape once within the surgical field.

6. The surgical retractor of claim 1, wherein the first engaging feature comprises detent and the second engaging feature comprises a tab.

7. The surgical retractor of claim 1, wherein the first engaging feature comprises lattice and the second engaging feature comprises a hook.
