Problems solved by technology

[0003] However, if the light guide connector is connected after the cold light source of the endoscope is turned on, or disconnected before the cold light source is turned off, the high-brightness light emitted by the cold light source of the endoscope will pass through the light outlet of the cold light source and directly Shooting, causing disturbance to the user, and may even sting the eyes in severe cases

Embodiment Construction

[0013] see figure 1 The cold light source of the endoscope has a light outlet 10. Inside the cold light source of the endoscope, a light source such as a xenon lamp with a parabolic reflector bowl or an LED lamp emits high-brightness illumination light. The light outlet hole 10 is inserted into the light outlet hole 10 by the light guide connector (not shown) of the endoscope, and connected with the cold light source of the endoscope. On the light exit path of the light exit hole 10, at least one light-shielding plate is arranged, and when the light-guiding connector is connected with the cold light source of the endoscope, the light-shielding plate is opened; when the light-guiding connector is connected with the endoscope When the cold light source is disconnected, the shading plate is closed. The specific position and connection structure of the shading plate on the light exit path of the light exit hole 10 , as well as the principle of realizing the opening and closing of...

Abstract

The invention relates to an endoscope cold light source with a shading device, and the endoscope cold light source can be used for solving the problem that a user is interfered because high-brightness light is directly emitted from a light outlet hole when an existing endoscope cold light source is disconnected from a light guide connector of the endoscope. The endoscope cold light source is provided with a light outlet hole, wherein the light outlet hole is connected with a light guide connector of the endoscope; a light outlet path of the light outlet hole is provided with at least one shading plate; when the light guide connector is connected with the endoscope cold light source, the shading plate is opened; when the light guide connector is disconnected from the endoscope cold light source, the shading plate is closed. The endoscope cold light source is simple in structure, and can be used for effectively preventing high-brightness light from being directly emitted from the light outlet hole of the endoscope cold light source and preventing the user from being interfered.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to an endoscope cold light source. Background technique [0002] Endoscopic devices are widely used in the medical field, and they are configured to have an elongated insertion part. By inserting the insertion part into the body, internal organs and the like can be observed, or as needed, using a Disposal instruments for various disposals. In an endoscope device, a light guide or the like is used to guide illumination light from an endoscope cold light source to illuminate a target site of a subject to obtain an endoscope image for observation or treatment. The end of the light pipe is connected to the cold light source of the endoscope through a light guide connector, and the light guide connector is inserted into the light outlet hole connected to the cold light source of the endoscope to lead out the cold light source of the endoscope. The illuminating light of the light sou...
