Abstract: The endoscopic device includes a main member having a front slot and a shaft member having a spiral strip selectively running through the slot. The spiral strip is connected to a rotational element whose front end is provided with an optical element. A camera support element is extended from the main member and a camera element is supported by the camera support element. By running the spiral strip through the slot to turn the rotational element and the optical element, a viewing direction of the camera element is altered by the optical element.

Abstract: A structure includes a goggles body including rim sections and temple sections, an imaging device arranged between the rim sections, light-emitting elements arranged on an outer edge of the rim sections, and an electricity supply element, a control module, a storage device, and a data transmission device arranged in the temple sections. A server host device is also included. The server host device includes a wireless transmission module, a recognition processing module, and a driving processing element. As such, a surgeon may wear the goggles body in a surgical operation to acquire supplemented lighting in the eyesight range and a function of recording the entire process of the surgical operation. The surgeon may take a motion of a predetermined hand gesture to issue a control instruction corresponding thereto in order to execute the control instruction on a medical device to allow the surgeon to control hardware necessary for the operation.
