Abstract
A system for performing anastomosis includes a plurality of staples, an annular staple support having structure for holding the staples, and a staple closing device for closing the staples to secure the canal ends together. A method for performing anastomosis and staples for performing anastomosis are also disclosed.
Core Innovation
The disclosed subject matter relates to a staple for performing anastomosis, the staple including first and second staple portions joined together at ends thereof at a junction so as to define an included space. The first staple portion includes structure for engaging a staple support, the engaging structure comprising a slot having a large diameter portion and a small diameter portion, and the slot is distanced from the junction.
The second staple portion includes structure for engaging a canal, wherein the structure for engaging a canal comprises a projection for piercing the canal. The projection extends into the included space, enabling canal piercing in relation to the included space defined by the joined staple portions.
An anastomosis system and method are disclosed using multiple circumferential staples retained by an annular staple support, the staple support releasing the staples upon closure. The method includes positioning and removing the annular staple support, folding a first canal end over the support to engage the staple projections, placing the second canal end over the folded end, closing and detaching the staples, and leaving an anastomosis junction with an unchanged lumen profile.
Claims Coverage
One independent claim is provided. The claim coverage focuses on the structure of a surgical staple used for anastomosis, particularly the included space defined by joined staple portions, canal-engaging piercing, and staple-support engagement via a slot with large and small diameter portions.
Anastomosis staple with included space at a junction
A staple for performing anastomosis includes first and second staple portions joined together at ends at a junction so as to define an included space.
Staple-support engaging slot with large and small diameter portions
The first staple portion includes staple-support engaging structure comprising a slot having a large diameter portion and a small diameter portion, with the slot distanced from the junction.
Canal-engaging piercing projection extending into the included space
The second staple portion includes canal-engaging structure comprising a projection for piercing the canal, the projection extending into the included space.
The independent claim defines an anastomosis staple whose first and second staple portions form an included space at a junction, where the first portion engages an annular staple support via a slot with large and small diameter portions, and the second portion pierces a canal using a projection extending into the included space.
