Embodiment Construction

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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

The invention discloses a cooling system for endoscope lighting and an endoscope. In the solution, a gas cooling circuit formed by a gas pipe is arranged in cooperation with an endoscope lighting structure. In the water-gas delivery system in the endoscope, and make the delivery gas in the water-gas delivery system flow through the gas cooling circuit as cooling gas. This solution cools the lighting structure in the endoscope by introducing the gas used to deliver to the observation window in the endoscope as a cooling source, which can greatly improve the performance of the endoscope without affecting the function and structure of the endoscope. The heat dissipation effect of the light-emitting element in the lighting structure inside the speculum effectively prevents the deterioration of the light-emitting element and prolongs the service life.

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 this improved endoscope, a light-emitting element such as a light-emitting diode (LED) is provided at the front end of the insertion part, 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 be co...
