ANASTOMOTIC SLEEVE DEVICE

摘要

An anastomotic sleeve or “cup” protection device incorporating distal and proximal sleeves or “cups”, also incorporating a staple-line buttress. The proximal colon is inserted into the proximal sleeve or cup and the shaft of the stapler anvil is passed through a hole in the closed end of the sleeve or cup. The distal sleeve or cup is placed over the head of the staple shaft, and inserted into the rectum for anastomosis. Closure and firing of the stapler creates a staple buttress line at the anastomosis, the proximal sleeve prevents leakage from the proximal colon and the distal sleeve protects the distal colon or rectum from anastomotic leak.

主权项

1. A system for performing a medical procedure comprising:
a) a stapler comprising: a detachable anvil head comprising an anvil surface and a hollow rod comprising a lumen protruding from the anvil surface, a stapler shaft comprising a stapler surface and a spike protruding from the stapler surface, and a shape cutter, wherein the anvil surface comprises a groove, wherein the stapler surface comprises a staple port and a cutter port wherein the cutter can advance through the cutter port, and wherein the spike is proportioned to fit inside the lumen of the hollow rod; and b) a support structure comprising: a first shield piece comprising a first support surface and at least one first wall comprising a first bottom edge wherein the first bottom edge is attached to the first support surface and a second shield piece comprising a second support surface, wherein the second shield piece is not attached to the first shield piece, wherein the first support surface and/or the second support surface comprises a hole, and wherein the first support surface and the second support surface align with the anvil surface and the stapler surface to provide for the delivery of a staple through the first support surface and the second support surface.
