Description

Technical Field

[0001] The utility model relates to the technical field of medical endoscopes, in particular to a light-filling system of an endoscope module. Background Art

[0002] In the medical field, medical endoscopes are often used to perform visual internal inspections of human internal organs, such as the stomach and urinary system. The endoscope system includes a light source, a scope system, and an image display system. The light source provides lighting for the endoscope system. The scope system converts the collected optical signals into digital signals, inputs them into the image display system, and is displayed by the image display system. Doctors can observe the internal images of the human body in real time. However, in actual use, since the light source is far away from the front end of the lens assembly, the image is not clear, which affects the surgical operation. Therefore, a fill light system needs to be set on the endoscope module.

[0003] The existing endoscope module fill light system includes a head end seat, which is provided with a No. 1 mounting hole and a No. 2 mounting hole, the number of the No. 2 mounting holes is two, a PCB-A board is fixedly connected inside the head end seat, a lens assembly is installed on the PCB-A board, the lens assembly can extend out of the No. 1 mounting hole, the PCB-A boards on both sides of the lens assembly are bonded with height fixing blocks through conductive silver glue, each height fixing block is bonded with a light source through conductive silver glue, the light source corresponds to the No. 2 mounting hole one by one, and the light emitted by the light source can illuminate the inspection area; due to the setting of the height fixing block, this technical solution shortens the distance from the light source to the front end of the lens assembly, thereby playing a role of fill light, but since the height fixing block is bonded to the PCB-A board through conductive silver glue, and the light source is bonded to the height fixing block through conductive silver glue, therefore, in the process of assembling the height fixing block and the light source, it is easy for the light source to be offset or tilted, resulting in poor clarity of the imaging picture, affecting the surgical operation. Utility Model Content

[0004] The utility model aims to provide a light-filling system for an endoscope module, so that the light source is not easily offset or tilted, and the imaging picture is clearer.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fill light system for an endoscope module, including a head end seat, a mounting hole is provided on the head end seat, optical fiber light guide columns are connected to the head end seat on both sides of the mounting hole, a PCB-A board is fixedly connected to the inside of the head end seat, a lens assembly is installed on the PCB-A board, the lens assembly can extend out of the mounting hole, light sources are installed on the PCB-A boards on both sides of the lens assembly, the optical fiber light guide columns are located directly above the light sources, and the light sources correspond to the optical fiber light guide columns one by one.

[0006] The beneficial effect of this solution is that when in use, the light emitted by the light source is gathered in the head end seat and transmitted to the front end of the lens assembly through the optical fiber light guide, ensuring that the front end of the lens assembly has sufficient light input and illumination, making the imaging picture clearer and facilitating surgical operations.

[0007] The advantages of the present technical solution in transmitting optical signals through optical fiber light guides are: optical fiber light guides only transmit light and do not conduct electricity, so that the optical signals they transmit are not affected by electromagnetic fields, thereby making the imaging clearer. At the same time, the optical signals do not generate electromagnetic radiation when transmitted in the optical fiber light guides, making the operation safer and more reliable. The attenuation of the optical signals in the optical fiber light guides is very small, and the optical signals can be effectively transmitted over a distance of tens or even hundreds of kilometers, thereby providing sufficient light input and illumination for the front end of the lens assembly, making the imaging clearer.

[0008] Since the light source of the present technical solution is directly mounted on the PCB-A board, the displacement or tilting of the height-fixing block and the light source during the assembly process in the prior art can be avoided; at the same time, the installation process of the light source is simpler and low-cost.

[0009] Furthermore, the optical fiber light guide column is detachably connected to the head end seat.

[0010] The beneficial effect of this solution is that since the optical fiber light guide column and the head end seat are detachably connected, it is convenient to replace the optical fiber light guide column.

[0011] Furthermore, the optical fiber light guide column is fixedly connected to the head end seat.

[0012] The beneficial effect of this solution is that since the optical fiber light guide column is fixedly connected to the head end seat, the stability of the optical fiber light guide column can be improved, and at the same time, the processing of the optical fiber light guide column and the head end seat is facilitated.

[0013] Furthermore, the optical fiber light guide column includes a cylindrical section and a spherical section which are connected in sequence, the cylindrical section is located directly above the light source, and the spherical section can extend out of the top of the head end seat.

[0014] The beneficial effect of this solution is that due to the setting of the spherical segment, the light emitted by the light source is transmitted to the spherical segment through the cylindrical segment and scattered in the spherical segment, so that the outlet end of the optical fiber light guide column is bright from any angle, and can provide sufficient light for the lens assembly, thereby making the imaging clearer.

[0015] Furthermore, the light source is an LED lamp.

[0016] The beneficial effect of this solution is: since LED lamps have the advantages of stable performance and long luminous time, using them as light sources can provide continuous light sources for the lens assembly. BRIEF DESCRIPTION OF THE DRAWINGS
