Method and device for full thickness resectioning of an organ
First Claim
1. A full-thickness resection system comprising:
- a flexible endoscope;
a stapling head slidably coupleable to the endoscope, the stapling head including;
a stapling mechanism having a rotatable staple driving cam and a plurality of staple driving members, each staple driving member being received within a corresponding one of a plurality of staple channels adjacent to a rotary path of the cam so that, when rotated along the path, the cam sequentially strikes the staple driving members driving each driving member distally through its respective staple channel;
an anvil moveably mounted thereto for movement relative to the stapling mechanism substantially along a longitudinal axis of the stapling head between a stapling position and a tissue receiving position; and
a tissue cutting mechanism;
a flexible sheath extending proximally from a proximal end of the stapling head, wherein, when the system is in an operative position within a body lumen, a proximal end of the sheath extends out of the body lumen; and
a locking mechanism which prevents operation of the tissue cutting mechanism until a stapling operation has been completed.

Abstract
A full-thickness resection system comprises 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 comprises 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 between a tissue receiving position and a stapling position and wherein a gap formed between the stapling head and the anvil is larger in the tissue receiving position than it is in the stapling position. A position adjusting mechanism is provided for moving the anvil and the stapling head between the tissue receiving and stapling positions and a staple firing mechanism sequentially fires a plurality of staples from the stapling head across the gap against the anvil and through any tissue received in the gap and a knife cuts a portion of tissue received within the gap. A control unit which remains outside the body is coupled to the stapling mechanism for controlling operation of the position adjusting mechanism and the staple firing mechanism.
