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. The intravascular therapeutic operating device of the present invention includes: a driving source which is provided to a case； a power transfer member which receives driving power of the driving source and rotates； a punching member which is combined to a front-end unit of the power transfer member； a punching member moving unit which is combined to the case and moving the punching member in the longitudinal direction； a guide pipe which is combined to the case and is arranged on the periphery of the power transfer member and punching member； a pulling line of which one side is combined to a front-end of the guide pipe； a guide pipe direction conversion unit to which the other end of the pulling line is combined for pulling the pulling line or the releasing the pulling condition of the pulling line； a blood vessel damage prevention pipe which is arranged on the periphery of the guide pipe； a support unit which is combined to the case and fixating one end of the blood vessel damage prevention pipe； and a blood vessel damage prevention pipe moving unit which is combined to the case and support unit for moving the blood vessel damage prevention pipe to a longitudinal direction. In the guide pipe, a plurality of direction conversion grooves with predetermined intervals is provided on the outer surface of the front-end unit.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 혈광손상방지관 이동부를 포함하며, 안내관은 선단부 측의 외주면에 간격을 이루어 다
