A kind of introscope spool stand of what is closed in this creation,Be the leading-out terminal of the what introscope long tube and for being added at long tube fixing end in tool guiding radian,Outer guiding sleeve,The spool stand of this creation includes: a pedestal and a spiral ontology with leading-out terminal and fixed line end； Wherein the spiral ontology is articulated on the pedestal； Wherein,If arc sleeve system can guide the long piping of introscope and take advantage of a situation out and (enter) to fix radian line except the what leading-out terminal and pedestal corresponding position； And arc sleeve on the fixation line end of the what spiral ontology is set,The inner arc sleeve system with the spiral ontology synchronous rotary,A fixed radian is maintained for guiding the introscope long tube Hou end,Make the long tube that best signal can be kept to connect with the image monitoring device signal outer,Also the long tube in spiral ontology can be maintained most preferably to wind state.本創作關於一種內視鏡用捲線架，係於該內視鏡長管之出線端以及供長管固定端處增設具導引弧度的內、外導引套筒，本創作之捲線架包含：一基架及一具有出線端及固定線端的捲線本體；其中該捲線本體樞接在該基架上；其中，設於該出線端與基架對應處之外弧形套筒係可導引內視鏡長管係以固定弧度順勢出(入)線；而設於該捲線本體之固定線端上之內弧形套筒，該內弧形套筒係隨該捲線本體同步旋轉，用來導引該內視鏡長管後端維持一固定弧度，使該長管可與該影像監視裝置訊號保持最佳之訊號連接外，亦可維持捲線本體內之長管最佳收捲狀態。
