METHOD OF SURGICAL STAPLING WITH END EFFECTOR COMPONENT HAVING A CURVED TIP

A surgical stapling instrument is operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force. In some instances the placement tip includes an arcuate bend, while in other instances the placement tip is straight. The placement tip can have a variety of non-rectangular lateral cross-sectional shapes. In some instances, the placement tip is made of a material of a specified durometer range and having a high color contrast. A distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force. 本发明公开了一种外科缝合的方法，该方法使用能够操作以压缩、缝合和切割组织的外科器械。器械包括主体、轴和具有一对钳口的端部执行器。放置末端从端部执行器的钳口中的一个钳口朝远侧延伸。当放置末端受夹持力时，放置末端能够弹性变形。在一些情况下，放置末端包括弓形弯曲部，而在其它情况下，放置末端是直的。放置末端可具有各种非矩形侧向横截面形状。在一些情况下，放置末端由具有指定硬度范围并且具有高颜色对比度的材料制成。放置末端的远侧端部可响应于
