일반적으로 척추 내시경은 내시경 내부에 환부를 볼 수 있는 카메라 시스템과 작업을 할 수 있는 작업 통로가 같이 존재하며 이로 인하여 좁은 내시경 작업통로와 카메라 시스템과 같은 고정된 각도의 작업 통로로 인하여 일직선 형태의 척추 내시경의 한계가 발생한다. 또한, 척추에는 두꺼운 근육층과 피부하 지방층을 가지고 있어 경피적으로 두 개의 시술공을 만들어서 내시경과 수술기구 삽입을 위한 통로를 만들어도 이 두 개의 통로가 치료 목적 부위에 정확하게 도달해서 일치된 작업공간을 만들어내는 것이 쉽지 않고 또한 숙련도가 많이 필요한 수술과정이 된다.In general, the spinal endoscope has a working system for working with the camera system that can see the affected area inside the endoscope, and thus, the spine has a straight shape due to the narrow endoscope working path and the fixed angle working path such as the camera system. Endoscopic limitations arise. In addition, the spine has a thick muscle layer and a subcutaneous fat layer, which creates two surgical holes percutaneously to create an endoscope and a path for insertion of surgical instruments. It is not easy to produce and requires a lot of skill.
종래에는 두 개의 통로가 치료 목적 부위에 정확하게 도달해서 일치된 작업공간을 만들어내기가 어려워 외부에서 움직이는 팔 형태의 고정장치를 내시경용 캐뉼라나 수술 장치용 캐뉼라에 고정하고 이 고정용 팔을 수술용 침대에 고정하여 사용하였으나 이 역시 정확하게 작업 공간을 일치시키고 안정되게 유지하는데 어려움이 있었다Conventionally, the two passages reach the treatment target accurately and it is difficult to create a consistent working space. Therefore, an externally movable arm-type fixing device is fixed to the endoscope cannula or the surgical device cannula and the fixing arm is fixed to the surgical bed. It was used to fix it, but it also had difficulty in keeping the work space exactly and stable.
상기와 같이 확장시술용 캐뉼라에 대해서는 국내등록특허공보 제10-1631908호 및 제10-1737997호 등에 개시된 바 있다.As described above, the expansion cannula has been disclosed in Korean Patent Publication Nos. 10-1631908 and 10-1737997.
