    摘要： The present invention discloses a completely laparoscopic staged hepatectomy using round-the-liver ligation, which is carried out as follows: (1) a complete laparoscopic operation is performed with general anesthesia using round-the-liver ligation, the branches of the portal vein of the hemiliver to be removed are ligated, meanwhile a tourniquet is used to tighten the connecting part between the right and the left hemilivers to block the communicating blood flow between the hemiliver to be removed and the hemiliver to be reserved, a drainage tube is put into the peritoneal cavity at the hepatic hilus, then close the peritoneal cavity, and the operation is completed; (2) the patient gradually resumes eating after the first operation, and recuperate for 6-15 days to make the volume of the hemiliver to be reserved increase to the expected volume of the future liver remnant, in which the expected volume of the future liver remnant should be at least 30-40% of the standard liver volume; (3) after the volume of the hemiliver to be reserved has increased to the expected volume of the future liver remnant, a complete laparoscopic liver resection is carried out with general anesthesia to remove the diseased hemiliver, and then the patient is nursed to be completely recovered.

    摘要： A ligator system for applying an expanded ligator ring to an anatomical region of a living being to be ligatured by the ring in its relaxed state, which comprises a ligator with a holding tube, which receives inside it the anatomical region to be ligatured in each case and with its outer surface keeps a number of ligator rings arranged one behind the other expanded, wherein the ligator system comprises at least one intermediate ring, which is arranged on the holding tube between two ligator rings and keeps the two ligator rings at a distance from one another in the direction of the longitudinal axis of the holding tube.

    摘要： A multiple band endoscopic ligation device comprises a single pull string and a plurality of beads positioned on said pull string and between each successive band. The device is configured to be coupled to the distal end of an endoscope and is used to deploy multiple elastic bands around target tissues to be ligated. The device includes a tapered cylindrical body about which a plurality of elastic bands are stretched and positioned. The pull string includes multiple sets of two beads fixed to the string wherein one bead is placed directly behind and in contact with the other. The string is wrapped around the device's body and under each band such that at least one pair of beads is positioned between the elastic bands and one pair of beads is positioned proximally to the most proximal band. As the string is pulled, the beads push the bands sequentially off the distal end of the device and around a tissue to be ligated. The use of two adjacent beads on the string to push off each band ensures that the bands will not slip over the beads, thereby preventing a misfire.
