The endoscope light source is used for emitting illumination light to an observed object, and the endoscope light source is provided with a light guide seat with a light guide hole inside, and the light guide hole can enable the light guide part of the endoscope to complete insertion or extraction operation.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Endoscopic systems have achieved widespread clinical use in the medical field. An endoscope system generally includes an endoscope light source, an endoscope processor, an endoscope, a monitor, and the like. The endoscope light source is used for emitting illumination light to an observed object, and the endoscope light source is provided with a light guide seat with a light guide hole inside, and the light guide hole can enable the light guide part of the endoscope to complete insertion or extraction operation. When the light guide portion of the endoscope is inserted into the light guide hole of the light guide holder, illumination light from the endoscope light source illumination portion can enter the light guide portion of the endoscope by beam coupling, thereby transmitting the illumination light to the illumination window at the tip portion of the endoscope head and irradiating the object to be observed at a certain divergent angle. In addition, in order to prevent the illumination light from the illumination part from exposing from the light guide hole of the light guide base without connecting the endoscope and causing damage to the human body, a light blocking member may be provided on the light emitting path of the light guide hole, and the light blocking member may block the light guide hole to block the illumination light from the illumination part from exposing from the light guide hole when the endoscope light guide part is not inserted into the light guide hole; when the light guide portion of the endoscope is inserted into the light guide hole, the light guide hole can be opened, and the illumination light from the illumination portion can enter the light guide portion of the endoscope. In view of biological safety, the endoscope needs to be designed to float, i.e. the endoscope cannot be connected with a ground design conductor; however, the endoscope light source casing is connected in the field, that is, the endoscope light source casing is connected with the ground holding conductor, so that the light guide seat of the endoscope light source cannot be made of a conductive metal material, but at least a non-conductive non-metal material capable of electrically isolating the light guide part of the endoscope from the endoscope light source is required to be partially used, so that the endoscope can still keep floating under the condition that the endoscope light guide part is inserted into the light guide seat of the endoscope light source.

However, during the use of the endoscope system, the endoscope light source is required to generate a high-brightness and high-convergence light beam to meet the illumination requirement of the endoscope system, and in the case that the light guide portion of the endoscope is inserted into the light guide hole, the converged illumination light beam can enter the light guide portion of the endoscope by means of light beam coupling and is transmitted to the illumination window at the head end portion of the endoscope through the light transmission medium of the endoscope, thereby illuminating the observed object. And under the condition that the light guide part of the endoscope is not inserted into the light guide hole, the converged illumination light beam can directly irradiate on the light blocking component. Particularly, when the spectral ratio of the high-frequency band in the spectrum of the illumination light is increased, the radiation energy of the converged illumination light beams is increased, and local high temperature of more than 200 degrees can be formed on the light blocking member, so that the local high temperature is conducted to the non-conductive non-metallic material by the light blocking member, and further, the risk of melting the non-conductive non-metallic material is brought, and the light guide seat is damaged.

In view of the above, the present application provides a light amount control method, a light amount control device, an endoscope light source, an endoscope system, and a computer-readable storage medium, which can control the intensity of the emitted illumination light within a preset illumination intensity range that does not damage the light guide holder when the endoscope is not inserted into the light guide holder, and fundamentally prevent the light blocking member from being rapidly heated up due to the accumulation of excessive energy of the illumination light, thereby reducing the risk of the light guide holder from being melted.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
