A video image display is attached to a video endoscopic surgical component such as video endoscope, an endoscopic surgical instrument, a carrier for coupling the endoscope and the instrument, or a cannula through which the endoscope or the instrument is passed into a body part. Attachment is by means of an attachment mechanism which may be adjusted to enable the display position to be varied with respect to the component to which it is attached. According to another embodiment, a carrier in the form of an elongated tube is employed to combine and relate the movement of the endoscope and endosurgical instrument, which, by means of the carrier, may be jointly inserted into a body part either directly or through a cannula, enabling the surgeon to operate both the endoscope and the instrument with a single hand. A video display attached to the endoscope or carrier and positioned near the instrument actuation handle provides the surgeon with a visual perspective similar to that encountered in open surgery.
