The invention discloses a puncture outfit easy for flexible operations of an apparatus and a using method. The puncture outfit comprises a casing
pipe,
puncturing rods, a sealing element and a sealingcover, wherein the sealing element is detachably mounted at the upper end of the casing
pipe in a sealing manner, the sealing cover is detachably mounted on the side away from the casing
pipe, of thesealing element, in a sealing and buckling manner, the cone end of each
puncturing rod sequentially penetrates through the sealing cover and the sealing element in a sealing manner to be inserted andlocated in a
puncturing rod passage located in the casing pipe, an air receiving pipe is arranged on the sealing element, and the inner end of the air receiving pipe penetrates through the puncturingrod passage in the casing pipe; and a
valve port achieving the sealing effect when
pneumoperitoneum is established is arranged on the sealing cover, and a sealing lip achieving the sealing effect when the apparatus penetrates through is arranged on the sealing element. In the inserting and drawing process of the apparatus, the sealing effect can be achieved only by one layer of the sealing element, the inserting and drawing friction when the apparatus penetrates through can be greatly reduced, the displacement of the casing pipe caused by the inserting and drawing process of the apparatus canbe avoided,
surgery risks can be reduced, convenience is provided for operations of a doctor, and besides, pain of patients can be well alleviated.
