- 손잡이(11)가 일끝단에 고정된 가압철심(12)을 전,후 이동할 수 있도록 내장한 작동몸체(14)에 중공체인 가요성의 외부튜브(73)를 밀폐되게 연결하고, 상기 가압철심(12)의 일끝단에는 상기 외부튜브(13)내에서 가압철심(12)의 전, 후 이동에 따라 이동할 수 있도록 가요성의 이동튜브(15)를 연결한 것에 있어서, 상기 가요성의 이동튜브(15)의 끝단에는 삽입튜브(20)를 연결고정하고, 상기 삽입튜브(20)의 끝단에는 상기 외부튜브(13)의 내부로 내장되는 단턱(22)이 일체로 형성된 연질재의 삽입단(23)을 연결고정하며, 상기 삽입튜브(20)에는 상기 삽입단(23)의 단턱(22)에서 부터 확장기구의 직경을 최소화하여 부피를 줄였을 때 발생하는 최대길이(L)보다 작은 거리에 상기 외부튜브(13)의 내경에 밀착되도록 상기 이동튜브(15)의 직경보다 큰 직경을 갖는 가압편(21)을 설치한 구조로 이루어진 것을 특징으로 하는 신체의 협착부위를 확장시키는 확장기구 삽입장치.
- 제1항에 있어서, 상기 외부튜브(13)에는 그 외주연에 상기 확장기구(5)의 직경을 최소화하여 부피를 줄였을때 발생하는 최대길이(L)를 설정하여 이와 동일한 길이(L)를 갖는 표시부(24)를 설치하여 이루어진 것을 특징으로 하는 신체의 협착부위를 확장시키는 확장기구 삽입장치.
