Problems solved by technology

The diameter of the collimator lens 3' is generally between 30-50mm, and the diameter of the corresponding filter wheel 4' is about 80-100mm, and the entire optical path length is usually on the order of 100mm. The rotating motor that drives the 4' rotation of the filter wheel requires a large torque and is difficult to install

Embodiment 1

[0027] Such as figure 2 and image 3 The endoscope multi-color lighting system shown includes a mirror body optical cable 1 and a light source assembly, and a filter wheel 4 that can rotate along its own central axis is arranged between the light source assembly and the mirror body optical cable 1. In this embodiment, The filter wheel 4 is a color wheel. The filter wheel 4 has a plurality of filter areas 41 distributed in an annular array, and the light source assembly is arranged opposite to the light entrance surface of one of the filter areas. Such as figure 2 and image 3 As shown, a rod-shaped light guide medium 2 is provided between the filter wheel 4 and the mirror body cable 1, and the light exit surface of the filter area opposite to the light source assembly is parallel to the light entrance surface of the light guide medium 2 and has a small shape. The gap fit is arranged, and the light exit surface of the light guide medium 2 is parallel to the light entry sur...

Embodiment 2

[0032] The structural principle of this embodiment is basically the same as that of the first embodiment, except that the light guide medium 2 is an optical cable.

Embodiment 3

[0034] The structural principle of this embodiment is basically the same as that of the first embodiment, except that the light source assembly includes a full-spectrum laser light source.

Abstract

The invention provides an endoscopic multicolor lighting system, belongs to the technical field of medical instruments and solves the problem that an existing endoscopic lighting system uses a collimating lens to couple light of a light source into a lens cable and has large size, high requirement on motor torque and high mounting difficulty. The endoscopic multicolor lighting system comprises a lens cable and a light source component; a filter wheel rotatable around its axis is arranged between the light source component and the lens cable; the filter wheel has multiple filter areas in circular array distribution; the light source component is arranged opposite an incoming light face of one filter area, a light-conducting medium is arranged between the filter wheel and the lens cable, anoutgoing light face of the filter area opposite the light source component is arranged opposite an incoming light face of the light-conducting medium, and an outgoing light face of the light-conducting medium is arranged opposite an incoming light face of the lens cable. The endoscopic multicolor lighting system with the LED light source has the advantages of high optical efficiency, small size, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an electronic endoscope lighting system, in particular to an endoscope multicolor lighting system. Background technique [0002] The electronic endoscope has an elongated insertion portion inserted into a subject, and an illumination window for illuminating an observation site in the subject with illumination light and an observation window for incident light reflected from the observation site are provided at the distal end of the insertion portion. The electronic endoscope is connected with the light source device, and the light source device provides illumination light and guides the light to the illumination window through the optical cable of the scope body. For example, a Chinese patent discloses an electronic endoscope system, a light source device, and a control method for the electronic endoscope system [the authorized announcement number is CN102860812B]. The ligh...
