Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0026] see figure 1 , the endoscope involved in this example generally has an illumination optical system 10 , an observation optical system 20 , a treatment instrument channel 30 and a water and air pipeline 40 inside the insertion portion.

[0027] The illumination optical system 10 is provided in the front end 50 of the insertion part, has an illumination window and an illumination structure (for example, LED), and emits illumination light through the illumination window to illuminate the subject.

[0028] The observation optical system 20 has an observation window at the front end of the insertion part to observe the subject, and specifically includes an objective lens unit and a camera module. The camera module converts the optical image co...

Abstract

A system for cool an endoscope for illumination and an endoscope are disclosed. The scheme adopts the gas cooling loop formed by the air pipe and the endoscope illumination structure, the inlet pipe and the air supply pipe of the gas cooling loop are respectively connected into the water-gas transmission system in the endoscope, and the gas conveyed in the water-gas transmission system can flow through the gas cooling loop as the cooling gas. The present scheme cools the illumination structure within the endoscope by introducing a gas for delivery to the viewing window as a cooling source. Without affecting the function and structure of the endoscope, the heat dissipation effect of the light emitting element in the inner lighting structure of the endoscope can be greatly improved, the deterioration of the light emitting element can be effectively prevented, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the endoscope technology, in particular to the cooling technology of the illumination assembly in the endoscope. Background technique [0002] Endoscopes are widely used in the medical field to diagnose diseased tissues in body cavities. When performing endoscopic observation, a light source for illuminating the object to be observed is required. In recent years, improved endoscopes have been proposed instead of combinations of light source devices and optical fibers. In such an improved endoscope, a light-emitting element such as a light-emitting diode (LED) is provided at the front end of the insertion portion, and the observation object is directly illuminated by the light emitted by the light-emitting element. [0003] When such a lighting solution is applied, although a large amount of light can be obtained, the light-emitting element LED will generate a lot of heat, so a corresponding heat dissipation structure needs to...
