Multi-purpose endoscope light source

Abstract

The invention relates to a multi-purpose endoscope light source which comprises a case. A circuit board, a switch power supply, a filter, a laser module and an LED (light-emitting diode) module are arranged in the case, the switch power supply, the filter, the laser module and the LED module are electrically connected with corresponding connecting terminals of the circuit board, and a light transmitting bundle socket is formed in the outer wall of the case. The light source is characterized in that an all-in-one optical fiber bundle is arranged in the case, a white LED and a plurality of single-color LEDs are arranged on the LED module, an output end of the laser module and the white LED and a plurality of single-color LEDs of the LED module are connected with a plurality of connectors ofone end of the all-in-one optical fiber bundle, and a synthesis output terminal of the other end of the all-in-one optical fiber bundle is connected with the light transmitting bundle socket. The light source is simple in structure and can provide various different narrow-band light sources according to operation requirements, and spectrum coupling and optical path switching structures are simplified.

Description

technical field [0001] The invention relates to an endoscope light source, in particular to a multipurpose endoscope light source. Background technique [0002] The existing medical endoscope cold light source is used for illumination during minimally invasive endoscopy or operation. [0003] Most of the endoscope light sources used in the traditional medical industry are xenon lamps as the core light source. This type of light source has problems such as short service life, high heat generation, large power consumption, etc., and the spectrum is relatively simple; with the development of science and technology, LED The brightness of the light-emitting element is continuously improved, and has the advantages of high brightness, long life, low heat generation, and low power loss, which perfectly replaces the traditional xenon lamp light source; the wavelength bandwidth of the laser is narrow, the monochromaticity is good, and the brightness is higher. High energy and high en...

Problems solved by technology

The structure of the device is complex, the positioning accuracy is high, and the cost is high. What's more, each light source can only provide a fixed or specific narrow-band spectrum to identify a small number of diseased tissues.

[0008] Generally, the spectral bandwidth of ordinary narrow-light LED light-emitting elements is still relatively wide, and the color is not pure enough; it can also be used in the field where narrow-band light imaging technology is currently used; but for some specific tissue lesions (will continue to be discovered in follow-up clinical trials) , this narrow-band light will have less pure color and more interfering light, resulting in poor imaging recognition of lesions; at this time, light with narrower bandwidth and purer color is required, and it is usually necessary to add an additional filter for filtering to obtain Narrowband light that requires a narrowband spectrum
