An endoscopic surgery device for the insertion and recovery of a haemostatic plug at the surgical site. The device comprises a tubular body suitable for slidingly housing the plug and a plunger slidingly engageable within the tubular body so as to push the plug outside thereof, and to place it in the surgical site. The plug is connected to a locator being of a suitable color, radio-opaque and floating relative to the internal organs, blood or other fluids present at the surgical site. At a distal end of the plunger, a handle is provided for gripping the locator for recovering the plug after use and retracting the plunger within the tubular body.
