It relates to the insertion device.

종래에는 예를 들어 심장 또는 혈관벽의 천공된 부위를 차단시켜주는 스텐트와 같은 삽입물의 경우 부피가 최소화된 상태로 시즈에 장입(loading) 되었다가 시즈속에서 전진하는 퓨셔(Pusher)로 밀어주는 것에 의해서 시즈밖으로 노출되면서 팽창하도록 된 것이어서 즉, 시즈속에 장입되어 있는 삽입물이 한번에 팽창되는 것이므로 시술할 때 인체내의 원하는 위치에 정확하게 시술하기가 매우 어려운 단점이 있었다.Conventionally, for example, an insert such as a stent that blocks the perforated area of the heart or blood vessel wall is loaded into the siege with a minimal volume and then pushed by a pusher advancing through the siege. Since it is intended to expand while being exposed to the outside of the siege, that is, the insert inserted in the siege is expanded at a time, so it is very difficult to accurately perform the procedure at the desired position in the human body.

그리고, 뇌동맥이 비정상적으로 부풀어 생기는 뇌동맥류를 치료하는데 사용 되는 종래의 색전코일 같은 삽입물의 경우 색전용 백금코일과 코일부셔의 연결부를 전기적으로 절단시켜서 시술해 왔었기 때문에 환자에게 쇼크를 줄 위험이 많았었을 뿐만 아니라 전기로 전달되는 부위가 딱딱하게 굳어지게 되어서 혈액의 원활한 흐름을 방해하는 것에 의한 부작용을 야기시기는 등의 문제점이 있었다.In the case of conventional embolic coils used to treat cerebral aneurysms in which the cerebral artery is abnormally swollen, the patient was shocked by the electrical connection between the platinum coil for coil and the coil bushing. Not only that, there were problems such as causing a side effect caused by the hardened portion of the electric delivery area to harden the blood flowing smoothly.

본 발명은 시술할 위치로 삽입될 삽입물과 이 삽입물을 밀어주는 푸셔를 물리적으로 연결시켜주거나 분리시켜줄 수 있도록 함으로써 원하는 위치에 정확하게 부작용을 유발시키지 않으면서 시술할 수 있는 의료용 삽입물 및 그 삽입장치를 제공하는데 있다.The present invention provides a medical insert and the insertion apparatus that can be performed without causing adverse side effects at the desired position by physically connecting or separating the insert to be inserted into the position to be inserted and the pusher pushing the insert.
