<P>PROBLEM TO BE SOLVED: To provide an improved circular stapler for eliminating technical difficulty caused during the surgery of hemorrhoids. <P>SOLUTION: The circular stapler for the surgery of hemorrhoids is demonstrated. This circular stapler includes an anvil, the stapler and a shaft for movably supporting the anvil in relation to a stapler head between an open position and a close position. This stapler is provided with at least one transition members, and each of these can transit arbitrarily and/or independently along the shaft. Each of at least one transit members is provided with a first end constituted so as to engage a pouch suture thread and a second end (e.g., the neck of the stapler) extending through a body. The transit member can transit arbitrarily along the shaft. In one embodiment, two transit members capable of independently transiting are provided. <P>COPYRIGHT: (C)2011,JPO&INPIT |
