The present invention is directed to a full-thickness resection system comprising a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism includes an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another. A position adjusting mechanism is provided for moving the anvil and the stapling head relative to one another. An integrated surgical retainer for use in the full thickness resectioning device is described. The integrated surgical staple retainer comprises a calibrating portion, a retaining portion, and a grasping portion. The calibrating portion defines a circular opening which has a diameter substantially equal to a diameter of a working channel of the full thickness resectioning device. The retaining portion has a lower surface adapted to limit movement of the surgical staples in the full thickness resectioning device and is adjacent to the calibrating portion of the integrated surgical staple retainer.
1. A surgical staple retainer of a full-thickness resection system, comprising: a calibrating portion defining a hollow area for slidably receiving an endoscope therein; a retaining portion including a positioning element which, when engaged by a corresponding structure in the full thickness res
1. A surgical staple retainer of a full-thickness resection system, comprising: a calibrating portion defining a hollow area for slidably receiving an endoscope therein; a retaining portion including a positioning element which, when engaged by a corresponding structure in the full thickness resection system maintains the surgical staple retainer in a predetermined position relative to the full thickness resection system to prevent surgical staples from being displaced from the full-thickness resection system, the retaining portion being connected to the calibrating portion; and a grasping portion connected to one of the calibrated portion and the retaining portion so that a user grasping the grasping portion may remove the retaining portion from the predetermined position to ready full-thickness resection system for firing of staples. 2. The surgical staple retainer of claim 1, wherein the hollow area is substantially circular and has a diameter substantially equal to a diameter of a working channel of the full-thickness resection system. 3. The surgical staple retainer of claim 1, wherein the retaining portion comprises a plurality of positioning elements that include protrusions, the positioning elements holding the integrated surgical staple retainer in the predetermined position. 4. The surgical staple retainer of claim 3, wherein the protrusions are formed as substantially hollow ridges. 5. The surgical staple retainer of claim 1, wherein the positioning elements are formed as grooves. 6. A surgical staple retainer of a full-thickness resection system, comprising: a retaining portion formed as a substantially semi-circular wall extending from a base, the base extending substantially within a plane perpendicular to the wall, wherein, when the surgical staple retainer is in an operative configuration within a full-thickness resection system, the retaining portion covers staple openings thereof to retain staples within the system; a calibrating portion coupled to the base and including an endoscope receiving opening extending therethrough; and a grasping portion coupled to the base so that a user may grasp the surgical staple retainer thereby and withdraw the surgical staple retainer from the operative configuration to expose the staples for operation of the full-thickness resection system. 7. The surgical staple retainer of claim 6, wherein a diameter of the endoscope receiving opening is substantially equal to a diameter of an endoscope receiving working channel of the full-thickness resection system so that the opening may be used to gauge the fit of an endoscope within the working channel. 8. The surgical staple retainer of claim 6, wherein, when the surgical staple retainer is in the operative configuration, the calibrating portion extends outside the full-thickness resection system.
