Abstract
A transanal inserter is disclosed which facilitates the atraumatic insertion of intra-anal surgical devices through the anus. The inserter has a tubular portion, a prolate distal end and a proximal end having a flange associated therewith. The prolate end is formed from a plurality of petal-shaped segments which deflect outward as an intra-anal surgical device is urged therethrough, into the colon or intestine. The flange formed at the proximal end of the inserter retains the inserter in place and prevents over insertion of the inserter beyond the anus. The inserter can be fabricated in varying lengths to accommodate surgical requirements. The inserter is fabricated from a plastic material with sufficient pliability to provide for deflection of the segments, while maintaining sufficient rigidity to prevent collapse of the inserter during insertion and use.
