  • Publication number: 20230225723
    Abstract: The present invention relates to an endoscope suturing device and, more specifically, to an endoscopic suturing device capable of suturing a range of incisions by using an endoscope. According to the present invention, a wide range of incisions can be continuously sutured with high suturing power by using an endoscope, the suturing procedure time can be shortened, and a suturing method using a suture can minimize leftover foreign substances in the body, and thus can prevent side effects caused by the foreign substances. In addition, by using an endoscope, suturing with high-reliability is possible regardless of the range of suture areas, and thus the present invention can be used for simple suturing procedures and various internal surgeries such as gastrointestinal reduction surgery and NOTES, which uses a natural orifice.
