Transparent outer tube endoscope structure

Abstract

The invention provides a transparent outer tube endoscope structure. The transparent outer tube endoscope structure comprises a transparent light-guide outer cannula, a lens set, imaging fiber, an outer reflective layer, an inner reflective layer, rear light-guide fiber and a handle, the lens set connected with the in-tube imaging fiber is arranged inside the top-front end of the transparent light-guide outer cannula, the outer reflective layer and the inner reflective layer cover the outer surface layer and the inner surface layer of the side face of the transparent light-guide outer cannula, the rear end of the transparent light-guide outer cannula is thickened and expanded inside the handle and then connected with the rear light-guide fiber. When an endoscope works, the rear light-guide fiber brings light into the body along the cannula wall of the light-guide outer cannula, and the outer reflective layer and the inner reflective layer separate the cannula wall of the transparent light-guide outer cannula from the outside world so as to prevent illumination light from disturbing imaging. Compared with an original endoscope, the specialized light-guide fiber space arranged in the outer cannula is saved, the overall diameter of the endoscope is decreased, the brightness is higher, the operation wound is smaller, the endoscope can enter a thinner cavity gap, and pain and complications of patients are reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a transparent outer tube endoscope structure. Background technique [0002] The eye has a delicate and complex anatomical structure, and it is difficult to directly observe the hidden areas inside the eye, such as the anterior chamber angle, the back of the iris, the ciliary body, and the peripheral retina, through traditional ophthalmic operating microscopes. Because these parts are difficult to expose and the nerves and blood vessels are dense, it brings great difficulties to the operation and greatly increases the risk of surgery. In addition, when the anterior segment has lesions, it is more difficult for us to observe the structures in the eye due to the occlusion of the lesions. . Endoscopes can pass through narrow pores, allowing us to observe their internal structures and operate under direct vision, thus being introduced into the medical field. The emergence of ophth...

Problems solved by technology

However, the overall diameter of endoscopes used in ophthalmic hospitals today is still relatively thick, and it is necessary to perform a large incision on the patient to be inserted into the body for inspection. This will inevitably cause certain pain to the patient, but due to its structure Difficult to reduce size to include inner tube, imaging fiber, illumination fiber and outer cannula
