Patent number: 11389166Abstract: The ligation device includes a tubular body having a tubular shape and including a hollow part into which a string-shaped body can be inserted. The tubular body includes a proximal opening and a distal opening at a proximal end part and a distal end part, respectively. The proximal opening and the distal opening communicate with each other via a lumen of the tubular body. The side of a first end part of the string-shaped body can be inserted into the hollow part. The tubular body includes, on the distal end part, a locking part capable of locking the side of a second end part of the string-shaped body, after the string-shaped body is wound around the target, in a state where the first end part side of the string-shaped body is inserted into the lumen.Type: GrantFiled: May 25, 2020Date of Patent: July 19, 2022Assignee: FORCE ENGINEERING CO., LTD.Inventors: Takanori Imai, Takaki Sawahata, Hiroshi Hirota, Shinichi Kanno, Shinichi Ono, Tomoyuki Sawahata, Tomohiro Murakami, Tomoaki Higuchi

Publication number: 20210161535Abstract: In a ligation device for performing ligation by inserting a string-shaped body wound around a target into a tubular body, an object is to provide a ligation device that does not require a special instrument during the insertion of the string-shaped body and offers excellent workability. A means for solving the problem is a ligation device 1 for ligating a target V. The ligation device 1 includes a tubular body 2 having a tubular shape and including a hollow part 5 into which a string-shaped body 20 can be inserted. The tubular body 2 includes a proximal opening and a distal opening at a proximal end part 3 and a distal end part 4, respectively. The proximal opening and the distal opening communicate with each other via a lumen 5 of the tubular body 2. The side of a first end part 21 of the string-shaped body 20 can be inserted into the hollow part 5.Type: ApplicationFiled: May 25, 2020Publication date: June 3, 2021Applicant: FORCE ENGINEERING CO., LTD.Inventors: Takanori IMAI, Takaki SAWAHATA, Hiroshi HIROTA, Shinichi KANNO, Shinichi ONO, Tomoyuki SAWAHATA, Tomohiro MURAKAMI, Tomoaki HIGUCHI
