The light guide beam transmits illumination light emitted by the light source into the endoscope through the optical fiber, and the illumination light is transmitted to the front end of the endoscope through the light guide optical fiber in the endoscope, so that the body cavity is illuminated to observe physiological conditions in the body cavity. At the connection position of the light guide beam and the first connector, if the light conducted by the light guide beam is not completely conducted and emitted into the endoscope, the lost light can be converted into heat to cause the temperature at the connection position of the light guide beam and the first connector to rise, and meanwhile, the lighting effect in a body cavity can be reduced.

As shown in fig. 1, the light emitting end face 12 of the light guide beam does not overlap with the light incident end face 13 of the endoscope, and part of the light is not emitted into the endoscope, so that the incident light flux is reduced, the temperature of the joint part is too high, and the illumination effect in the cavity is deteriorated. As shown in fig. 2, the light emitting end face 12 of the guide beam is not parallel to the light incident end face 13 of the endoscope, and the incident light of the guide beam is not incident perpendicular to the light incident end face of the endoscope, resulting in poor illumination effect and an increase in the temperature of the joint position.
