摘要：The present invention relates a surgical instrument for performing hepatic resections, and the surgical instrument is called Chang's needle. The Chang's needle of the present invention comprises a stainless steel sheath and a stainless steel inner needle with a hook near the top of the inner needle. The advantageous features of the Chang's needle of the present invention are described as follows. The Chang's needle makes the hepatic resections safer and simplifies the surgical technique for hepatic resections thereby reducing the training time needed for surgeons. The Chang's needle is simple in mechanism, light and handy structure, small in size and low in price, and can be repeatedly sterilized and used. In addition to the traditional hepatic resections, the Chang's needle is suitable for use in segmental and partial hepactectomy of left lateral segment, and partial hepatectomies along the inferior border of the liver under a window with gasless-fashioned laparoscopic surgery.
