Description

Technical Field

[0001] This invention belongs to the field of endoscopy technology, specifically relating to an anti-fog structure for gastrointestinal endoscope lenses. Background Technology

[0002] Gastroscopy and colonoscopy are the most important endoscopic diagnostic tools in gastroenterology. They are divided into two categories: gastroscopy and colonoscopy. They are mainly used to observe lesions of the esophagus, stomach, duodenum and colorectum. The core function of gastroscopy and colonoscopy is to transmit mucosal surface images in real time through a high-definition camera to detect lesions down to the millimeter level.

[0003] In clinical examinations, gastroscopy and colonoscopy involve inserting the endoscope through the mouth or anus into the patient's digestive tract to capture minute lesions on the mucosal surface in real time. However, in practice, the endoscope often faces two types of interference: firstly, contaminants such as mucus, food residue, and blood in the digestive tract easily adhere to the lens surface, forming irregular obstructions; secondly, the temperature difference between the human body cavity and the endoscope's operating temperature can cause condensation, forming a thin fog in front of the lens and further blurring the field of vision. This double contamination not only reduces image clarity but may also force doctors to repeatedly adjust the lens angle or flush the passage, prolonging the examination time and even leading to missed diagnoses of minute lesions due to limited field of vision.

[0004] Therefore, there is an urgent need to provide an anti-fog structure for gastrointestinal endoscope lenses to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an anti-fog structure for gastrointestinal endoscope lenses.

[0006] The technical solution adopted to solve the above technical problems is: to provide a gastrointestinal endoscope lens anti-fog structure, including an instrument body, wherein a controller, an adjustment mechanism and a water filling mechanism are fixedly installed on the surface of the instrument body, and further includes;

[0007] A connecting tube is fixedly connected to the surface of the instrument body, and a probe is fixedly connected to the end of the connecting tube. The connecting tube and the probe are used to extend into the human organ. The adjustment mechanism is used to adjust the position of the probe.

[0008] A lens body is fixedly mounted on the surface of the probe, and the lens body is used to capture high-definition images of the mucous membrane surface of internal organs.

[0009] The present invention is further configured such that: the adjustment mechanism includes a left-right adjustment knob and an up-down adjustment knob, both of which are rotatably connected to the surface of the instrument body.

[0010] The above technical solution allows for left-right adjustment of the probe head using the left-right adjustment knob and up-down adjustment of the probe head using the up-down adjustment knob, thereby enabling adjustment of the lens body in all directions.

[0011] The present invention is further configured such that: the water filling mechanism includes a water tank, the water tank is fixedly installed on the surface of the instrument body, a water inlet pipe is fixedly connected to the surface of the water tank, and a sealing cap is detachably installed on the water inlet pipe.

[0012] Through the above technical solution, the water tank is used to store sterile water. The sealed cover protects the sterile water inside the water tank from external contamination and also prevents heat loss from the water tank, keeping the sterile water within a certain temperature range.

[0013] The present invention is further configured such that: a first water pump is fixedly installed inside the water tank, and two hoses are fixedly connected inside the first water pump, one hose being fixedly connected to the inside of the water tank, and the other hose being fixedly connected to the inside of the probe.

[0014] With the above technical solution, when the first water pump is started, heated sterile water is delivered to the working channel inside the probe head, which is used to heat the lens body and wash away contaminants on the surface of the lens body at the same time.

[0015] The present invention is further configured such that a heater is fixedly installed inside the water tank.

[0016] The above technical solution heats the sterile water inside the water tank using a heater.

[0017] The present invention is further configured such that: both the connecting pipe and the probe head have a central pipe inside, the probe head has a working channel inside, and the end of the other flexible tube is fixedly connected to the inside of the working channel.

[0018] Through the above technical solution, the central pipeline is used for instruments to enter and perform other operations on the gastrointestinal organs, and the working channel is used for the temporary storage of heated sterile water.

[0019] The present invention is further configured such that: a second water pump is fixedly installed inside the working channel, and a water suction pipe and a water outlet pipe are fixedly installed on the surface of the second water pump; the end of the water suction pipe is fixedly connected to the inside of the working channel, and the end of the water outlet pipe passes through the working channel and is located above the lens body.

[0020] Using the above technical solution, the second water pump is started, the suction pipe draws in the heated sterile water, and the water is delivered to the top of the lens body through the outlet pipe. After the solenoid valve is started, the surface of the lens body can be rinsed.

[0021] The present invention is further configured such that: a heating tube is fixedly connected to the surface of the water outlet pipe, the heating tube is spirally distributed on the back of the lens body, one end of the heating tube is fixedly connected to the inside of the working channel, and an electromagnetic valve is fixedly installed on the surface of the water outlet pipe, the electromagnetic valve being located on the side of the connection between the water outlet pipe and the heating tube and near the end of the water outlet pipe.

[0022] Through the above technical solution, most of the heated sterile water is transported to the inside of the heating tube through the water outlet pipe. The heating tube is in close contact with the lens body to heat the lens body, reducing the fog on the surface of the lens body. The temperature of the heated sterile water is always slightly higher than the internal temperature.

[0023] The present invention is further configured such that: a placement groove is provided on one side of the lens body, the heating tube is fixedly installed inside the placement groove, a water outlet is provided inside the lens body, and the front end of the water outlet tube is fixedly installed inside the water outlet.

[0024] With the above technical solution, the water outlet is used to place the water outlet pipe. After the solenoid valve is opened, some sterile water is discharged from the water outlet to the surface of the lens body to rinse the contaminants.

[0025] The present invention is further configured such that the output terminal of the controller is electrically connected to the input terminals of the first water pump, the heater, the second water pump, the solenoid valve, and the lens body.

[0026] Through the above technical solution, the controller can control the opening and closing of the first water pump, heater, second water pump, solenoid valve and lens body, ensuring rapid response at each step.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention is equipped with a heating tube that is tightly fitted to the surface of the lens body, forming a highly efficient heat conduction structure. When sterile water is delivered to the inside of the heating tube through the outlet pipe, the heating tube rapidly heats up and evenly transfers the heat to the surface of the lens body, avoiding blurred vision caused by fogging. In addition, using sterile water as a medium avoids the risk of secondary contamination and meets medical-grade safety standards, thus balancing functionality and hygiene requirements.

[0029] 2. The present invention is equipped with a water outlet pipe and a water outlet hole. The water outlet pipe is located above the lens body. When the surface of the lens body is blocked by fog or contaminants, the solenoid valve is opened, and some heated sterile water is discharged from the water outlet hole to rinse the fog or contaminants on the surface of the lens body. This can achieve real-time and efficient lens body maintenance and significantly improve the continuous availability of gastrointestinal endoscopes under complex working conditions.
