Abstract
This document provides methods and materials for retracting tissue during a minimally invasive surgical procedure (e.g., an endoscopic surgical procedure). For example, methods and materials for using an expandable space-occupying tissue retractor during an endoscopic surgical procedure such as a laparoscopic cholecystectomy procedure or a NOTES procedure are provided.
Claims20
A tissue retractor configured for deployment from a tubular component during a minimally invasive surgical procedure, wherein said tissue retractor comprises an expandable portion, wherein said expandable portion is in a compressed configuration when located within said tubular component, wherein said expandable portion is in an expanded configuration when advanced out of said tubular component, wherein said expanded configuration is capable of retracting tissue at a surgical site during said minimally invasive surgical procedure, wherein said expandable portion defines an opening at a distal end region of said expandable portion, wherein at least a portion of said expandable portion comprises transparent material configured to allow visualization of at least a portion of the tissue being retracted by said expandable portion, wherein an endoscopic tool is capable of advancing through the expanded region of said expandable portion when said expandable portion is in said expanded configuration and through said opening into contact with tissue at said surgical site.
A tissue retractor configured for deployment from a tubular component during a minimally invasive surgical procedure, wherein said tissue retractor comprises a plurality of wire structures configured to form at least part of an expandable portion and at least part of a tubular portion, wherein said expandable portion is in a compressed configuration when located within said tubular component, wherein said expandable portion is in an expanded configuration when advanced out of said tubular component, wherein said expanded configuration is capable of retracting tissue at a surgical site during said minimally invasive surgical procedure, wherein said expandable portion defines an opening at a distal end region of said expandable portion, wherein an endoscopic tool is capable of advancing through the expanded region of said expandable portion when said expandable portion is in said expanded configuration and through said opening into contact with tissue at said surgical site.
A tissue retractor configured for deployment from a tubular component during a minimally invasive surgical procedure, wherein said tissue retractor comprises a mesh material configured to form at least part of an expandable portion of said tissue retractor, wherein said expandable portion is in a compressed configuration when located within said tubular component, wherein said expandable portion is in an expanded configuration when advanced out of said tubular component, wherein said expanded configuration is capable of retracting tissue at a surgical site during said minimally invasive surgical procedure, wherein said expandable portion defines an opening at a distal end region of said expandable portion, wherein an endoscopic tool is capable of advancing through the expanded region of said expandable portion when said expandable portion is in said expanded configuration and through said opening into contact with tissue at said surgical site.
