In the present invention, in the snare device, a snare portion 240' is provided at the distal end to perform trapping and ablation of body tissue, and the core wire cord 200' is operated in the tube 210 forward, backward, and rotated. It is connected to the rear end of the core cord 200' and includes an operation unit 100' for manipulation of the core cord 200', wherein the operation unit 100' includes an operation unit body 110' and the operation unit body ( 110') includes a movable tool 120' to which a support shaft 125' having a rectangular cross-section structure connected to an end of the core wire cord 200' is connected to the forward and reverse sliding, and connected to the core wire cord 200'. ) Has a structure in which the first and second spring members 232' and 234' wound in different forward and reverse directions are wound on the outer circumferential surface of the core wire 220', and the movable tool 120' is a second. A finger hole 122' and a third finger hole 124' are respectively provided, and the second finger hole 122' is provided in the second finger hole 122' and the third finger hole 124'. And when the user's finger enters the third finger hole (124'), it moves forward and backward toward the entered finger to provide a snare device provided with a gap adjusting module for pressing and fixing the finger. Accordingly, there is an effect of providing a snare device and a method of manufacturing the same, which are useful for both the handler and the patient by making the handling of the snare device more stable and easy.본 발명은 스네어 장치에 있어서, 선단부에 신체 조직의 포획 및 절제를 행하기 위해 올가미부(240')가 마련되고 튜브(210) 내에서 전,후진 및 회전 동작되는 심선코드(200')와, 심선코드(200')의 후단부에 연결되어 심선코드(200')의 조작을 위한 조작부(100')를 포함하며, 상기 조작부(100')는 조작부 몸체(110')와, 상기 조작부 몸체(110')에 전,후진 슬라이딩 이동되고 상기 심선코드(200')의 단부와 연결된 사각단면구조의 지지샤프트(125')가 연결되는 가동구(120')를 포함하되,상기 심선코드(200')는 심선(220')의 외주면에 서로 다른 정,역방향으로 권취된 제 1,2스프링부재(232',234')가 각각 권취된 구조를 가지며, 상기 가동구(120')는, 제2 핑거홀(122')과 제3 핑거홀(124')이 각기 구비되며, 상기 제2
