Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a gastroscope with lens cleaning function. Background Technology

[0002] Gastroscopy, as an important medical device, is widely used in the examination and diagnosis of digestive system diseases, especially playing a crucial role in the early screening and treatment of gastrointestinal diseases. During the use of traditional gastroscopes, over time, the lens surface is easily contaminated by bodily fluids (such as saliva and gastric juice). These contaminants adhere to the lens surface, resulting in an unclean lens surface, ultimately leading to blurred image transmission, affecting the doctor's observation and diagnosis, and in severe cases, potentially impacting the accuracy of the diagnostic process.

[0003] To address this issue, some endoscopes have begun to incorporate cleaning functions, but most existing technologies rely solely on manual cleaning or external spraying to clean the lens. These methods not only have limited cleaning effectiveness but may also affect the smoothness of the procedure and the accuracy of the examination, increasing the difficulty of the procedure and patient discomfort.

[0004] Therefore, there is an urgent need for a technology that can clean the lens surface in real time during the use of gastroscopy, automatically removing potential contaminants to ensure image quality and improve the efficiency and comfort of gastroscopy. The purpose of this invention is to address the shortcomings of existing gastroscopy technology by proposing a gastroscopy with a lens cleaning function. This is achieved by adding a cleaning module, a cleaning nozzle, and connecting pipes to automatically clean the lens, ensuring clear image transmission throughout the examination.

[0005] There is a gastroscope (publication number: CN204410774U). The unloading platform in the existing technology has the following inconveniences:

[0006] 1. Inadequate cleaning effect: Most current gastroscopy cleaning techniques rely on manual or external spray cleaning. These methods are difficult to effectively remove bodily fluids and dirt adhering to the lens surface, especially after prolonged use or during highly complex operations. Residues may still remain on the lens surface, leading to decreased image quality and affecting the accuracy of examination and diagnosis. Therefore, there is an urgent need for a gastroscopy with lens cleaning function. Utility Model Content

[0029] In this embodiment, a data cable 5 is provided on the back of the LED light module 10, and the data cable 5 is connected to an external power source.

[0030] In this embodiment, an image transmission optical fiber 6 is disposed in the middle of the back of the image acquisition lens 8, and the image transmission optical fiber 6 passes through the zoom motor 7 and connects to an external image device.

[0031] In this embodiment, data lines 5 are provided on both sides of the lower end of the image transmission optical fiber 6, and the image acquisition lens 8 and the zoom motor 7 are connected to an external control center through the data lines 5 on both sides of the lower end of the image transmission optical fiber 6.

[0032] This embodiment discloses a gastroscope with a lens cleaning function, including a gastroscope housing, a cleaning module, an image acquisition lens, an LED light module, a zoom motor, and related tubing systems. The gastroscope is designed to effectively clean the lens surface during actual use, ensuring image quality and improving operational convenience and efficiency.

[0033] Endoscope housing: The endoscope housing forms the overall frame of the endoscope, protecting the internal components from external damage and providing shape and support. The lens is located at the front of the housing, and the cleaning module is positioned above it, ensuring the stability of the device during use and facilitating cleaning.

[0034] Cleaning Module: Located at the top of the endoscope housing and connected to a connecting pipe, the cleaning module is responsible for initially rinsing the lens surface by spraying liquid through the cleaning nozzle. When the image becomes blurry due to bodily fluid contamination on the lens surface, the cleaning module activates, spraying water through the nozzle and using airflow to blow away the liquid on the lens, ensuring the lens surface remains clean to restore a clear image.

[0035] Cleaning nozzles: The cleaning nozzles are located at the bottom of the cleaning module, facing the lens to ensure that water and airflow can directly clean the lens surface. When dirt or bodily fluids adhere to the lens surface, the cleaning nozzles spray liquid at a suitable angle, and the airflow, combined with purging, quickly removes the contaminants.

[0036] Connecting Pipes: The connecting pipes, through their internal channels, effectively conduct cleaning liquids and gases to the cleaning nozzles. A baffle plate at the lower end of the pipe helps maintain a stable flow of liquids and gases, preventing improper mixing or obstructed airflow and ensuring the high efficiency of the cleaning process.

[0037] Image acquisition lens: Located at the rear center of the endoscope, it is responsible for acquiring images of the stomach and transmitting them to external imaging equipment. LED light modules are installed on both sides of the lens to provide sufficient light source, ensuring clear imaging even in the relatively dark areas of the stomach.

[0038] LED Light Module: The LED light module is positioned on both sides of the image acquisition lens, providing a strong light source to illuminate the area and ensure the lens can clearly capture the desired image. Throughout use, the LED light module remains operational to provide a stable light source. A data cable connects to the back of the light module, allowing it to be connected to an external power source for continuous power supply.

[0039] Zoom Motor: A zoom motor is equipped at the rear of the image acquisition lens to adjust the lens focal length, ensuring that the lens can be adjusted to near or far as needed to obtain a clear image. The zoom motor is connected to an external control system via an image transmission fiber optic cable, allowing doctors to adjust the focal length in real time to adapt to the examination needs of different body parts.

[0040] Image transmission fiber optic cable: An image transmission fiber optic cable is located on the back of the image acquisition lens to transmit the acquired gastric images to external imaging equipment. This fiber optic cable connects to the external equipment via a zoom motor, ensuring high-quality image transmission. During this process, the image transmission fiber optic cable not only transmits image data but also connects to an external control center via data cables on both sides, ensuring real-time monitoring and data feedback of the gastroscopy procedure.

[0041] Complete usage process:

[0042] Start-up Phase: Before use, all components inside the endoscope housing are pre-connected according to the design. During startup, external power supplies power the LED light module and zoom motor via a data cable, ensuring the light source and lens focusing function are working properly. The doctor operates the control center to activate the image transmission fiber optic cable, and the image acquisition lens begins to acquire real-time images of the stomach.

[0043] Cleaning requirements during the examination: If the image is blurred due to contamination of the lens surface with bodily fluids or dirt during a gastroscopy, the doctor activates the cleaning module via the control center. The cleaning module then begins to work, with water and gas from the connecting pipes being sprayed onto the lens surface through cleaning nozzles. The airflow sweeps away the cleaning liquid, quickly removing the dirt from the lens.

[0044] Real-time image acquisition and cleaning coordination: While the cleaning module is operating, the image acquisition lens continues to acquire images, while the zoom motor adjusts the focal length as needed to ensure the lens can accurately focus on different areas of the stomach. The cleaning process does not interfere with image acquisition; the two work in coordination to ensure the smooth progress of the entire gastroscopy examination.

[0045] Image data transmission and feedback: During image acquisition, the acquired images are transmitted to external imaging equipment via optical fiber, while a data cable simultaneously transmits relevant data to the control center. Doctors can view the image data in real time and make adjustments as needed. The operation of the cleaning module and the transmission of image acquisition data do not interfere with each other, ensuring the efficient operation of the gastroscopy.

[0046] In summary, this embodiment, through the coordinated work of various modules, ensures stable image quality and real-time cleaning of the lens surface during gastroscopy, greatly improving the efficiency of gastroscopy and reducing image blurring caused by lens contamination, thereby providing doctors with clear and stable image data.
