The invention relates to an anvil tip covering of an automatic blood vessel anastomat in vivo and a manufacturing method thereof. The body is made of a catheter, one end of the body is provided with an opening, and a hole is arranged between two ends of the body. When the body is sleeved to the free end of the anvil of the automatic blood vessel anastomat in vivo, the free end of the anvil is penetrated into the opening, and the position of the opening facing the back of the anvil and adjacent to the free end is made so that the body is in the position of A guide part is formed between the other end and the opening, and the guide part is tilted into a hook shape towards the outside and the upper part of the anvil.In this way, the anvil of the automatic vascular anastomat in the body can enter the bottom of the vessel smoothly through the guidance of the hook shaped guide part, and the vessel can be placed on the anvil, so as to cut the vessel and close the incision of the vessel.本發明係一種體內血管自動吻合器之砧尖端覆套及其製法，係由導尿管製成一覆套的本體，本體之一端設有一開口，本體的兩端之間設有開孔，當本體穿套到體內血管自動吻合器之砧之自由端穿入開口，並讓開孔位面對砧之背面且鄰近自由端之位置，使得本體在其另端到開孔之間形成一導引部，且導引部朝向砧之外部及上方翹起成勾狀。如此，體內血管自動吻合器之砧透過勾狀的導引部的導引，即可順利地進入到血管的底部，並讓血管被置放在砧上，以便於切割血管即封閉血管的切口。
