Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and specifically relates to an external beam guide for a medical rigid endoscope. Background Technology

[0002] Currently, the application of beam guides in the medical field is particularly prominent, especially in endoscopic surgery. Images are transmitted via fiber optics to a subsequent signal processing system and displayed in real-time on a dedicated monitor, allowing doctors to perform surgical procedures accordingly. Beam guides are widely used in endoscopic examinations and treatments in the medical field. For example, in hysteroscopy, beam guides are used to deliver light, ensuring a clear surgical field. Furthermore, beam guides are also used in laparoscopic surgery, enabling examination and treatment through minimally invasive procedures, offering advantages such as less trauma and faster recovery. However, beam guides with conventional adhesive structures are not heat-resistant, have low light transmittance, and a lifespan of approximately 1-2 years.

[0003] Therefore, in order to address the problems of existing beam guides being unable to withstand high temperatures, having low light transmittance, and having a short service life, there is a need to provide an external beam guide for medical rigid endoscopes. Utility Model Content

[0027] Example 1:

[0028] An external beam guide for a rigid medical endoscope includes a protective tube, a light inlet section, and a light outlet section;

[0029] The aforementioned protective tube, light inlet section, and light outlet section are all equipped with optical fiber filaments 1, and the aforementioned optical fiber filaments 1 are continuous optical fiber filaments 1;

[0030] The light-inlet section is located at one end of the protective tube, and the light-outlet section is located at the other end of the protective tube.

[0031] One end of the aforementioned optical fiber 1 is fused to one end of the aforementioned light-inlet section.

[0032] The above structure, by fusing one end of the optical fiber 1 with one end of the light-inlet section, makes the connection between the light-inlet section and the optical fiber 1 more stable, resistant to high temperatures, and thus greatly improves its service life.

[0033] The cross-section of the aforementioned optical fiber filament 1 is hexagonal. Setting the cross-section of optical fiber filament 1 to a regular hexagonal shape significantly improves its light transmittance.

[0034] The aforementioned protective tube comprises a metal spiral tube 2 and an integrated glass fiber and silicone tube 3; the metal spiral tube 2 is housed inside the integrated glass fiber and silicone tube 3, and the aforementioned optical fiber filament 1 is disposed within the metal spiral tube 2. The outer layer of the integrated glass fiber and silicone tube is silicone, and the inner lining is a glass fiber mesh. That is, the integrated glass fiber and silicone tube 3 serves as the outer protective layer, while the metal spiral tube 2 provides elasticity and toughness, further protecting the optical fiber filament 1 disposed inside.

[0035] The aforementioned light-inlet section includes a first tube 4, a converter head 5, and a handle 6. One end of the first tube 4 is threadedly connected to one end of the converter head 5, and one end of the handle 6 is connected to the other end of the converter head 5. A first hardware connector 9 is internally fitted into the other end of the handle 6, and the first hardware connector 9 is welded to one end of the metal spiral tube 2. The converter head 5 allows for the replacement of different models of the first tube 4 as needed. The first tube 4 is the light-inlet end; the handle 6 is an insulator used to isolate current and heat; the threaded connection between one end of the first tube 4 and one end of the converter head 5 allows for replacement of the converter head 5 as needed. Welding the first hardware connector 9 to one end of the metal spiral tube 2 prevents the optical fiber filament inside the metal spiral tube 2 from falling off due to dragging, thus extending the service life of the device.

[0036] The aforementioned optical fiber 1 is fused to the other end of the aforementioned first tube 4. That is, the end of the optical fiber 1 is fused to the head of the light-inlet end, resulting in a more stable connection and resistance to high temperatures.

[0037] The light-emitting section includes a connector 7 and a second tube 8. A second metal fitting is internally fitted into one end of the connector 7, and the second metal fitting is welded to the other end of the metal spiral tube 2. The other end of the connector 7 is threadedly connected to one end of the second tube 8. The connector 7 can be replaced by threading as needed.

[0038] The aforementioned optical fiber 1 is fused to the other end of the aforementioned second tube 8. By fusing the optical fiber 1 to the other end of the second tube 8, the connection method of the light-emitting part is made more stable and resistant to high temperatures, thereby further extending the service life of the device.

[0039] The aforementioned connector 7 is equipped with two mounting brackets of different sizes. These two mounting brackets allow the light-gathering unit to be mounted in machines with different ports.

[0040] Specifically, the external beam guide for a medical rigid endoscope provided by this utility model includes a protective tube, a light-inlet section, and a light-outlet section. Each of the protective tube, light-inlet section, and light-outlet section contains a continuous optical fiber filament 1. The light-inlet section is located at one end of the protective tube, and the light-outlet section is located at the other end of the protective tube. One end of the optical fiber filament 1 is fused to one end of the light-inlet section. The cross-section of the optical fiber filament 1 is hexagonal. This design eliminates the instability and poor heat resistance of adhesive bonding, and by fusing the optical fiber filament 1 into a regular hexagon, its light transmittance is significantly improved (by 30%-50%). Based on the optimization and stability of its structure and process, its service life is also significantly extended.

[0041] This device is used in thoracic and laparoscopic image processing systems, working in conjunction with electronic endoscopes and displays. It processes images acquired by the electronic endoscope to a clearer level before transmitting them to the display, providing doctors with accurate and effective information for diagnosis and treatment.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
