| 摘要 |
This invention is a device for assisting in anastomosis for tubular structures. The basic device (10) has a generally cylindrical shape with a pair of insertion arms (12), and at least one depression (14) that provides a space for the needle to move through within the tubular structures while simultaneously providing support so that the suture needle thrust does not collapse the tubular structure wall. The depressions (14) may be configured to guide the path of the needle. A bridge (16) connects the arms. The device aids in preventing the needle from inadvertently coming in contact with the wall opposite that of the wall being sutured by physically blocking the needle and/or by providing visibility to the user. The method includes an initial suture to join the structures, inserting the device into the openings of the two structures, placing sutures in the walls adjacent to the depression (14), optionally rotating the device so a depression is aligned with each suture as it is being placed, removing the device, and tightening the sutures to complete the anastomosis.
