    Abstract: A method and apparatus (10) for attaching a tubular graft (20) to a body structure (332) is disclosed. The apparatus (10) includes a central rod (12) with an anvil (14) attached at a distal end (16) thereof. Driver pins (24) move distally to eject staples (210) which are housed in a cartridge (26). The staple cartridge (26) has an outer circumference sufficient to accommodate everted end (34) of tubular graft (20), and an inner diameter sufficient to accommodate a majority of the tubular graft (2) therein. Accordingly, the method includes positioning the rod (12) in the graft (20), everting an end (34) of the graft around a shoulder (36) of the staple cartridge (26), inserting the anvil (14) through an opening (334) in the body structure (332), compressing the graft (20) and the body structure (332) between the anvil (14) and shoulder (36), and moving the driver pins (24) distally to engage and drive the staples (210), thus stapling the graft (20) to the body structure (332).

    Abstract translation: 公开了一种用于将管状移植物(20)附接到身体结构(332)的方法和装置(10)。 装置(10)包括具有附接在其远端(16)处的砧座(14)的中心杆(12)。 驱动销(24)向远侧移动以排出容纳在盒(26)中的订书钉(210)。 钉仓(26)具有足以容纳管状移植物(20)的脱开端(34)的外圆周,以及足以容纳其中大多数管状移植物(2)的内径。 因此,该方法包括将杆(12)定位在移植物(20)中,使移植物的端部(34)围绕钉仓(26)的肩部(36)旋转,将砧座(14)插入开口 (332)中,在砧座(14)和肩部(36)之间压缩移植物(20)和主体结构(332),并且使驱动销(24)向远侧移动以接合和驱动 订书钉(210),从而将移植物(20)装订到身体结构(332)。
