Abstract

The invention provides an endoscope which comprises an endoscope tube and a heating lens, and the heating lens is arranged at one end of the endoscope tube. The heating lens comprises a glass substrate, a transparent heating layer and an electrode layer, wherein the transparent heating layer is arranged on the glass substrate; the electrode layer is arranged on the transparent heating layer. The endoscope provided by the embodiment of the invention comprises the endoscope tube and the heating lens, and the design that the heating lens comprises the glass substrate, the transparent heating layer and the electrode layer is adopted, so that the lens of the endoscope can directly heat, and demisting can be realized without the help of external heating equipment. Through the design of the transparent heating layer, on one hand, the influence on the lens transmittance is small, and the visual observation effect is not influenced; and on the other hand, the layered transparent heating layer is well combined with the glass substrate, so that the temperature distribution of the lens is uniform, the heating efficiency is high, and the lens is more practical.

Description

technical field [0001] The present invention generally relates to the technical field of medical equipment, and in particular, relates to an endoscope. Background technique [0002] Given the advantages of less trauma, less postoperative scarring, shorter recovery time for patients, and lower cost, endoscopic surgery has become a commonly used type of surgery worldwide. Lens fogging often occurs due to changes in the internal environment during endoscopic surgery. Clinicians usually remove the fog on the outer surface of the lens by taking the lens out of the body and putting it into hot water or wiping it manually, which not only affects the continuity of the doctor's operation, but also increases the operation time, causing a certain degree of damage to the doctor and the patient. troubled. [0003] In the prior art, defogging is achieved by adding heating wires on the surface of the lens or wrapping an electric heating film on the mirror tube, but these defogging method...
