An endoscopic surgical system for use in endoscopic surgery including an endosurgical instrument having an elongated shaft and an end-effector operably mounted to a distal end of the shaft. A video endoscope device includes an elongated telescope portion containing a distal viewing face, and a coupling device couples the instrument to the endoscope device. This coupling substantially maintains the relative position of the elongated shaft adjacent the telescope portion such that the endoscope viewing face is rearward of the distal end effector to view the distal end-effector from a position along the shaft. A handle portion is provided operably coupled to the coupling device in a manner enabling the distal end-effector and the viewing face to be manually positioned as a single unit during endoscopic surgery. The handle portion is further configured to manually operate the end-effector. A video display device is operably coupled to the coupling device at a viewing angle and location therealong wherein an image of the end-effector displayed on the display device appears to be a substantially direct view of the end-effector that is positioned in-line with the insertion shaft.
