Variable cap device for Endoscopic Submucosal Dissection

摘要

The present invention relates to a variable cap device for endoscopic submucosal dissection. This, in a state mounted on the tip of the endoscope tube to be inserted into the body, accommodates the cauterizer exposed to the front of the tip of the endoscope tube, exposing the cauterizer only when cauterizing the object with the cauterizer, and when not cauterizing the cauterizer a transparent fixing cap surrounding the distal end of the endoscope tube and providing an accommodation space between the endoscope tube and the outer circumferential surface; an elastic part installed in the receiving space of the transparent fixing cap and outputting an elastic force; A variable cap is included to be slidably installed in the receiving space, to move forward by the action of the elastic part to accommodate the cauterizer, or to move backward by an external force to expose the cauterizer. The variable cap device for endoscopic submucosal dissection of the present invention as described above is constricted when entering the lower part of the submucosal layer and widened when tissue incision is made to secure a field of view, so that the detachment of the submucosal layer can be performed more efficiently do.
