Cold light source device of medical endoscope

Abstract

The invention relates to a cold light source device of a medical endoscope, which is mainly suitable for lighting during an endoscopic surgery on a human body. The cold light source device comprises a machine case, a light box, a fan, an output light hole mechanism and a light adjusting part with a light screen, and is characterized by also comprising a reflector, a condenser, an LED light and a radiator, wherein the reflector, the condenser, the LED light and the radiator are sequentially arranged and positioned in the light box and are on the same axis as the output light hole mechanism; the axis of the light adjusting part is parallel with the axis of the output light hole mechanism and the light screen has an involute panel structure with a variable radium; the output light hole mechanism comprises a light hole nut, a light hole body, an insulator, a light hole radiator and an insulating connector; the LED light has a panel structure formed by uniformly distributing a plurality ofLEDs; and the reflector is provided with a reflector hole. The cold light source device is bright, long in service life and reliable under the condition of the same power, is safe and reliable in useand avoids damages to the human body.

Description

A cold light source device for medical endoscope technical field The invention relates to a medical endoscope cold light source device, which is mainly suitable for illuminating in the endoscopic operation of the human body. Background technique In the prior art, many medical devices such as endoscopes need to use cold light sources for illumination. However, more xenon lamps are used at present, and xenon lamps consume a lot of energy, have a lot of heat dissipation, and have a short working life. Therefore, there is no cold light source for endoscopic surgery with reasonable structural design and long service life. Chinese Utility Model Patent No. ZL2007201117450 discloses a technology and structure of "automatic lamp changing medical cold light source"; however, the medical cold light source uses a light bulb, which consumes a lot of energy, heats up a lot, has a short service life, and the structural design is not enough Reasonable. Chinese Utility Model Patent No...
