A full-thickness resection system (100) is disclosed. In an embodiment for the resection system (100), the system may include a flexible shaft, a flexible guide member (120) disposed within the flexible shaft, a stapling mechanism (140) disposed around the flexible guide member (120), and a grasper (130). The stapling mechanism (140) has an elongated portion that is at least partially disposed within the flexible shaft. The stapling mechanism (140) includes a stapling arm (150) and an anvil arm (160). The stapling arm (150) has a longitudinal axis (LSA) and includes a stapling head (152) having a longitudinal axis (LSA). The anvil (160) includes an anvil head (162). The stapling arm (150) and anvil arm (160) extend from the elongated portion of the stapling mechanism (140) and are moveable with respect to each other between a tissue receiving position and a stapling position. The grasper (130) extends through the flexible shaft and is adapted to grasp a portion of a tissue that is to be excised from an organ in the patient's body. The grasper (130) is movable in an axis that is perpendicular to the longitudinal axis of the stapling head.

La présente invention concerne un système de résection complète. Dans un mode de réalisation, le système peut comprendre une tige souple, un élément guide souple placé à l'intérieur de la tige souple, une agrafeuse placée autour de l'élément guide souple et un organe de préhension. L'agrafeuse comprend une partie allongée qui est partiellement placée à l'intérieur de la tige souple. L'agrafeuse comprend un bras d'agrafage et un bras d'enclume. Le bras d'agrafage possède un axe longitudinal et comprend une tête d'agrafage possédant un axe longitudinal. L'enclume comprend une tête d'enclume. Le bras d'agrafage et le bras d'enclume s'étendent depuis la partie allongée de l'agrafeuse et ils peuvent se déplacer l'un par rapport à l'autre entre une position de réception de tissu et une position d'agrafage. L'organe de préhension s'étend à travers la tige souple et il est apte à saisir une partie d'un tissu devant être excisé d'un organe dans le corps d'un patient. L'organe de préhension peut se déplacer dans un axe qui est perpendiculaire à l'axe longitudinal de la tête d'agrafage.
