內視鏡之光學結構

The present invention provides an optical structure of endoscope, which utilizes a first light outlet set on one side of a first tubular member, an optical fiber component arranged on an inner side of the first tubular member, a first lens arranged adjacent to one side of the optical fiber component, and a second lens arranged adjacent to a side of the first lens away from the optical fiber component. The first lens and the second lens respectively have a first angle and a second angle. A reflector is arranged adjacent to a side of the second lens away from the first lens, wherein the position of the reflector corresponds to the position of the first light outlet so as to reflect a light emitted from the optical fiber component out of the first light outlet. A first transparent device is disposed at the first light outlet. The first angle is greater than 5DEG and less than 10DEG. The second angle is greater than 5DEG and less than 10DEG°. The optical structure of endoscope also includes a second tubular member sleeved on the outside of the first tubular member. A second light outlet is set on one side of the second tubular member. The position of the second light outlet corresponds to the position of the first light outlet so that the light passes through the first light outlet and the second light outlet in sequence. A second transparent device is disposed at the second light outlet. The optical structure of endoscope further includes a first motor disposed at one end of the first tubular member for controlling the rotation of the first tubular member, and a second motor disposed on one side of the first motor for controlling the first motor and the left and right movement of the first tubular member.
