An insertion device for a flexible ring retractor such as a flexible annular ring retractor. The tool and method are conducive to use with a retractor constructed from a more fragile material such as silicone elastomers, but still manage stronger and stiffer retractors such as those constructed from polyurethanes.

Center Bore Insertion Tool and Method for Flexible Cannula/Retractors 


An insertion device for a flexible ring retractor such as a flexible annular ring retractor.  The tool and  method are conducive to use with a retractor constructed from a more fragile material such as silicone  elastomers, but still manage stronger and stiffer retractors such as those constructed from  polyurethanes. 


Insertion of soft elastomeric material retractors into an abdominal wound becomes increasingly difficult  with smaller sized retractors and smaller sized surgical incisions.  The traditional "flip and chip"  technique is difficult to perform using only fingers based on these size limitations.  Existing art for  insertion tools utilize multi‐step mechanisms, multi‐component parts, and typically have sharp edges  that would cause damage to softer materials and most typical elastomers. 


A tool to capture one annular ring of a flexible fixed length retractor.  The tool goes through the center  of a retractor that uses the traditional "flip and chip" technique and allows the "flip and chip" ring to  stay collapsed within a channel for insertion and is then released once the ring and tool are placed into  the patient's abdomen.
