Abstract
The invention aims to provide a connecting device for realizing signal feedback aiming at an illumination optical cable, and the connecting state of the illumination optical cable and an endoscope is detected by realizing the feedback of optical signals, so that the problem that strong light is emitted from a light outlet of the illumination optical cable to damage eyes of a user when the illumination optical cable is not connected with the endoscope is solved.
Description
Technical Field
The invention relates to an illumination optical cable for connecting an endoscope and an endoscope cold light source, in particular to a connecting device for realizing signal feedback inside the illumination optical cable, and belongs to the technical field of medical appliances.
Background
In minimally invasive surgery, an endoscope system provides a series of functions such as illumination, imaging, image processing and image display of anatomical structures in a human body, in the process, a cold light source transmits illumination light into an endoscope through an illumination optical cable, the illumination optical cable emits illumination light to illuminate an imaging view field of the endoscope after the illumination light is emitted from the front end of the endoscope, the light inlet end of the illumination optical cable is connected with the cold light source, and the light outlet end of the illumination optical cable is connected with the endoscope. In the practical use process, there are the phenomenon that the cold light source is opened when the illumination optical cable is not inserted, or the illumination optical cable is pulled out when the cold light source is not closed, and the phenomenon that the cold light source is opened when the illumination optical cable is connected with the cold light source but not connected with the endoscope, or the phenomenon that the illumination optical cable is disconnected with the endoscope when the cold light source is not closed, and when the above phenomena occur, strong light is emitted from a cold light source light outlet or an illumination optical cable light outlet, so that eyes of a user are uncomfortable, especially in recent years, with the application of a fluorescent imaging technology, the endoscope cold light source can emit laser with the intensity of up to 10W, and high-intensity laser is directly emitted from the cold light source light outlet or the illumination optical cable light outlet, so that serious conditions such as user burn can occur.
At present, there is a method for solving the above-mentioned problems in the endoscope cold light source, but the method is limited to controlling the connection of the illumination optical cable and the light outlet of the cold light source, and only can ensure that the cold light source has no light output when the illumination optical cable is not connected with the cold light source, such as an endoscope cold light source with a shading device in patent 201410158145.4, and an in-situ detection device, a cold light source and an endoscope in patent 202010006406.6, but the problem that strong light is directly emitted from the illumination optical cable when the illumination optical cable is not connected with the endoscope or when the endoscope is disconnected with the illumination optical cable still exists, so the prior art still needs to be improved.
In addition, patent 202011634375.5 also provides a solution to the problem that when an illumination optical cable is not connected with an endoscope, strong light is emitted from a light outlet of the illumination optical cable to cause damage to eyes of a user, however, the existing medical cold light source illumination optical cable on the market can generally only transmit illumination light of a cold light source to the endoscope.
