摘要：
The present invention provides an intravascular therapeutic operating device which is used to cure blood vessels by removing chronic total occlusion (CTO) lesion within blood vessels. An intravascular therapeutic operating device of the present invention includes a driving source installed in a case； a power transfer member which rotates by receiving driving power from the driving source； a punching member which is coupled with the front end of the power transfer member； a punching member moving unit which is connected to the case and moves the punching member in the longitudinal direction； a guide pipe which is connected to the case and is arranged on the periphery of the power transfer member and punching member； a pulling rope of which one side is connected to the front end of the guide pipe； a guide pipe direction conversion unit with which the other end of the halyard is connected to pull or release the pulling rope； a blood vessel damage prevention pipe which is arranged on the periphery of the guide pipe； a support unit which is connected to the case and fixates one end of the blood vessel damage prevention pipe； and a blood vessel damage prevention pipe moving unit which is connected to the case and the support unit and moves the blood vessel damage prevention pipe in the longitudinal direction. In the blood vessel damage prevention pipe, extension units are provided at predetermined intervals on the outer periphery of the front end, and a cutting groove is formed adjacent to the extension units.본 발명은 혈관 내에서 만성전폐쇄(Chronic total occlusion； CTO) 병변 등을 제거하여 혈관을 치료하는데 이용되는 혈관 치료용 수술장치를 개시한다. 본 발명의 혈관 치료용 수술장치는 케이스에 제공된 구동원, 구동원의 구동력을 전달받아 회전하는 동력전달부재, 동력전달부재의 선단부에 결합된 천공부재, 케이스에 결합되어 상기 천공부재를 길이 방향으로 이동시키는 천공부재 이동부, 케이스에 결합되며 동력전달부재와 천공부재의 외주에 배치되는 안내관, 안내관의 선단부에 일측이 결합되는 당김줄, 당김줄의 타단이 결합되며 당김줄을 당기거나 담김 상태를 해제하는 안내관 방향전환부, 안내관의 외주에 배치되는 혈관손상방지관, 케이스에 결합되며 혈관손상방지관의 일단을 고정하는 지지부, 케이스와 지지부에 결합되어 상기 혈관손상방지관을 길이 방향으로 이동시키는 혈관손상방지관 이동부를 포함하며, 혈관손상방지관은 선단부측 외주면에 일정한
