Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the specific implementation manners of the endoscope and inspection method of the present invention will be described below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The endoscope of the embodiment of the present invention, such as figure 1 As shown, it includes an inner tube 100, an outer tube 200, a lens (not shown) and a cold light source 300 (white circle in the figure). Same as the traditional endoscope structure, the lens of the endoscope according to the embodiment of the present invention is arranged at the front end of the endoscope, and the cold light source 300 is arranged between the outer tube 200 and the inner tube 100 at the front end of the lens. Different from the traditional endoscope, the e...

Abstract

The invention discloses a borescope and an inspection method. The borescope comprises an inner tube, an outer tube, a lens and cold light sources, wherein the lens is arranged at the front end of the borescope; the cold light sources are arranged between the outer tube and the inner tube which are arranged at the front end of the lens; the borescope also comprises a heat light source which is arranged in a gap between the cold light sources. The borescope and the inspection method, disclosed by the invention, use the characteristic that most energy is converted into heat energy to be given off during shining of the heat light source and use the heat light source to heat the front end of the lens of the borescope so as to reduce the temperature difference between the lens and an inspection cavity and play a role of fogging resistance. The borescope disclosed by the invention integrates the heat light source in the range of the original layout of the cold light sources without preseting a parking space for a heating device which is arranged newly, so that the size of the front end of the whole borescope keeps unchanged so as to avoid the phenomenon that the size of the front end of the borescope is enlarged caused by the fact that the heating device is further arranged.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an endoscope and an inspection method. Background technique [0002] When an endoscope is used for medical diagnosis or surgery, it is generally sent into a warm body cavity. Due to the large temperature difference between the inside and outside of the body cavity, the water vapor in the body is very easy to condense when it encounters a cold lens, thus forming a layer of fog, which makes the image quality displayed on the monitor relatively poor, which in turn affects the work of doctors. Contents of the invention [0003] Based on this, it is necessary to provide an endoscope and an inspection method that can effectively prevent fogging for the problem that traditional endoscopes are prone to fogging. [0004] A kind of endoscope provided for realizing the purpose of the present invention, comprises inner tube, outer tube, lens and cold light source, and described lens is ...
