Description

Technical Field

[0001] The present invention relates to the technical field of endoscopic ultrasonography, and particularly to an endoscopic ultrasonography for detecting the digestive tract wall and a using method thereof. Background Art

[0002] The detection of the digestive tract wall is crucial for the early detection of digestive system diseases. As an important diagnostic tool, endoscopic ultrasonography can provide detailed information on the wall layer structure of the digestive tract, helping to evaluate the location, size, and nature of lesions.

[0003] However, traditional endoscopic ultrasonography faces several major challenges in actual use. During digestive tract examinations, the ultrasonic probe and the lens of the camera are easily covered by mucus or other substances in the digestive tract, which seriously affects the imaging quality and reduces the diagnostic accuracy. Existing cleaning methods usually rely on external flushing or manual cleaning, with low efficiency and unstable effects. To improve the cleaning efficiency, some high-end endoscopes may be equipped with simple flushing structures for automatic cleaning. However, traditional flushing nozzles do not flush thoroughly and are prone to clogging, and it is difficult to completely remove stubborn stains or tissue residues attached to the lens only by water flushing. These substances may form a thin film, hindering the penetration of ultrasonic waves or affecting the quality of optical imaging. Therefore, an endoscopic ultrasonography for detecting the digestive tract wall and a using method thereof are needed to solve the above problems. Summary of the Invention

[0011] Preferably, for the ultrasonic endoscope for detecting the digestive tract wall of the present invention, elastic scraping pieces are uniformly arranged on the outer end surface of the cleaning tongue, and the elastic scraping pieces are several raised triangular prism-shaped silica gel strips.

[0012] Preferably, for the ultrasonic endoscope for detecting the digestive tract wall of the present invention, spring wires are uniformly arranged in the side wall of the cleaning tongue, the shape of the spring wires is the same as the shape of the cleaning tongue, and the spring wires are made of titanium alloy.

[0013] Preferably, for the ultrasonic endoscope for detecting the digestive tract wall of the present invention, the spraying flip cover is installed on the top of the installation groove, a rotating shaft is provided on the side end surface of the spraying flip cover, a torsion spring is provided on the rotating shaft, and the spraying flip cover is rotatably connected to the sliding rack through the cooperation of the rotating shaft and the torsion spring.

[0015] A method for using an ultrasonic endoscope for detecting the digestive tract wall includes the following steps:

[0016] Step 1: Equipment assembly. Connect the probe body to the detection device through a connecting wire.

[0017] Step 2: Conduct detection through the probe body.

[0018] Step 3: Clean the camera on the probe body through the cleaning mechanism.

[0019] Step 4: Remove the probe body and disassemble and clean it.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Through the linkage structure design of the sliding frame, elastic ring and water storage cavity, and in cooperation with the water pressure control of the water flow through holes, the present invention realizes the intelligent telescopic function of the nozzle. When the water pressure increases, the sliding frame squeezes the elastic ring to move outward, exposing the first nozzle, and the water flow directly flushes the camera lens, effectively removing the interference of digestive tract mucus on imaging. After the water supply stops, the elastic ring drives the sliding frame to reset, and the nozzle retracts into the probe body to avoid external blockage. At the same time, during the reset process, the first nozzle continuously sprays a small amount of water to form a positive pressure, further preventing foreign objects from invading the nozzle holes. This structure solves the problems of residual pollution or blockage of the nozzle after traditional endoscope cleaning, and significantly extends the service life of the equipment while ensuring the cleaning effect.

[0022] 2. The present invention adopts a combined structure of a spiral hollow silica gel tongue depressor and an elastic scraper, combined with the synergistic effect of the air flow through holes and the titanium alloy spring wire, to achieve a dual cleaning mode of physical scraping and air flow purging. When high-pressure air is introduced into the air supply pipe, the tongue depressor unfolds and sequentially scrapes stubborn attachments on the lens through the surface triangular prism-shaped silica gel scraper, and at the same time, the air flow ejected from the pressure relief port synchronously completes the debris purging. After the cleaning is completed, the elastic restoring force of the titanium alloy spring wire drives the tongue depressor to automatically retract and reset. This structure breaks through the limitation of single water washing cleaning, especially significantly improves the cleaning effect for viscous secretions or tissue debris, and the titanium alloy material ensures long-term elastic stability in a corrosive environment.

[0023] 3. Through the dynamic cooperation design of the spray flip cover and the arc-shaped water supply hole, the present invention constructs a self-maintenance mechanism for the cleaning component. When the tongue depressor unfolds, the spray flip cover is lifted and aligned with the water supply hole, and the second nozzle automatically flushes the surface of the tongue depressor in the reverse direction to remove the residues on the scraper. After resetting, the flip cover closes the installation groove under the action of the torsion spring, effectively blocking the intrusion of digestive tract contents. This dynamic sealing and self-cleaning design solves the problem that the cleaning component of traditional equipment is easily contaminated, ensures the reliability of the mechanism operation during multiple cleaning cycles, and at the same time realizes the efficient utilization of cleaning resources through the intelligent switching of the water flow path.

[0037] Embodiment 1

[0038] Please refer to Figures 1 - 12 , an ultrasonic endoscope for detecting the digestive tract wall, including a probe body 1 and a connecting line 2, and a cleaning mechanism 3 is arranged on the probe body 1;

[0039] An ultrasonic probe 101, a camera 102, and a fill light 103 are arranged on the probe body 1. A main line 201, a first expansion hole 202, a first auxiliary data line 203, a second auxiliary data line 204, a water flow hole 205, and an air flow hole 206 are arranged in the connecting line 2. A second expansion hole 104 corresponding to the position of the first expansion hole 202 is arranged on the probe body 1. The probe body 1 is installed on the connecting line 2. The cleaning mechanism 3 includes a slide carriage 301, an elastic ring 302, a first nozzle 303, a spraying flap 304, and a cleaning tongue 305. A slide groove 105 that is slidably matched with the slide carriage 301 is arranged in the probe body 1. A water storage cavity 3015 is arranged in the cleaning slide carriage 301. The first nozzle 303 and the spraying flap 304 are installed on the slide carriage 301 and are connected to the water storage cavity 3015 in a through manner. The elastic ring 302 is sleeved on the slide carriage 301.

[0040] Furthermore, a water inlet 3011 communicating with the slide groove 105 is arranged on the back surface of the water storage cavity 3015. The first nozzle 303 is fixedly installed on the side end surface of the slide carriage 301. A water inlet 3011 communicating with the slide groove 105 is arranged on the connecting line 2. A limit flange 3013 is arranged at the edge of the slide carriage 301 near the water inlet 3011. The slide carriage 301 and the probe body 1 are elastically slidably connected through the elastic ring 302.

[0041] Water is supplied to the probe body 1 through the water flow hole 205 of the connecting line 2. The water flow enters the chute 105, increasing the pressure inside the chute 105. As a result, the sliding frame 301 squeezes the elastic ring 302 and slides outward, and the first nozzle 303 is exposed to flush the lens at the front end of the camera 102, thus avoiding the attachment of digestive tract mucus on the lens surface and affecting the detection effect. When cleaning is not required, the water supply is stopped, the water pressure in the chute 105 is insufficient, and the sliding frame 301 resets under the action of the elastic ring 302. The first nozzle 303 retracts into the probe body 1, thus avoiding blockage caused by the exposure of the first nozzle 303. Moreover, during the retraction process of the sliding frame 301, the first nozzle 303 still continuously sprays water slowly outward. After being completely retracted, the first nozzle 303 is blocked by the side wall of the chute 105 and stops spraying water, keeping the inside of its spray holes in a positive pressure state, eliminating the possibility of blockage.

[0042] Further, a dark groove 3016 is provided on the side end face of the sliding frame 301. The first nozzles 303 are evenly installed in the dark groove 3016, and the spraying direction of the first nozzles 303 faces the camera 102.

[0043] A certain installation space is reserved for the first nozzles 303 through the dark groove 3016, avoiding the protrusion of the first nozzles 303 and the extrusion and wear with the inner wall of the chute 105, which affects the service life of the nozzles, or avoiding the interference of the nozzles with the movement of the sliding frame 301. The nozzles accurately face the camera 102 for spraying water, and can effectively remove the mucus attached to its surface.

[0044] Further, an installation groove 3017 is provided on the upper end face of the bottom of the sliding frame 301. The cleaning tongue 305 is fixedly installed in the installation groove 3017. The cleaning tongue 305 includes a cleaning part 3051 and an air supply pipe 3052. The air supply pipe 3052 is fixedly installed at the bottom of the installation groove 3017. The cleaning tongue 305 is a spiral hollow silica gel roll, and the cleaning tongue 305 is installed on the air supply pipe 3052 and is connected to it in a through manner.

[0045] When high-pressure air is introduced into the air supply pipe 3052, the air flow enters the cleaning tongue 305. The cleaning tongue 305 unfolds outward under the action of the air pressure, so that the cleaning tongue 305 extends towards the camera 102 end, wiping off the dirt on the front lens of the camera 102, improving the cleaning effect, and avoiding the problem of incomplete flushing and affecting the probe detection. The installation groove 3017 is in the shape of a right-angled trapezoid, which is convenient for the unfolding of the cleaning tongue 305.

[0046] Further, an air inlet hole 3012 communicating with the air supply pipe 3052 is provided in the sliding frame 301. An air inlet 30521 is provided on the side end face of the air supply pipe 3052. The air inlet hole 3012 and the air inlet 30521 are connected in a through manner through a connecting pipe. A hose is used to connect between the air flow hole 206 and the air inlet hole 3012. A pressure relief port 30511 is provided at the end of the cleaning part 3051.

[0047] Air is supplied to the cleaning tongue 305 through the air flow passing through the air inlet hole 3012 and finally through the air supply pipe 3052, causing the cleaning tongue 305 to extend outwards. There is a pressure relief port 30511 continuously ejecting high-pressure air to blow the surface of the lens. In the way of hose connection, the device can also supply air stably during the sliding process of the sliding frame 301.

[0048] Furthermore, elastic scraping blades 30512 are uniformly arranged on the outer end surface of the cleaning tongue 305. The elastic scraping blades 30512 are several raised triangular prism-shaped silica gel convex strips.

[0049] When the cleaning tongue 305 extends outwards, it contacts the protective glass at the front end of the camera 102. During the unfolding process, the elastic scraping strips on the surface of the cleaning tongue 305 sequentially scrape the protective glass, thus greatly improving the cleaning effect.

[0050] Furthermore, spring wires 30513 are uniformly arranged inside the side wall of the cleaning tongue 305. The shape of the spring wires 30513 is the same as that of the cleaning tongue 305. The spring wires 30513 are made of titanium alloy.

[0051] The elasticity of the cleaning tongue 305 is enhanced by the spring wires 30513, so that when the air flow stops supplying after cleaning, it can automatically retract and reset, thus improving the stability of the device. The spring wire 30513 structure made of titanium alloy has good elasticity and corrosion resistance.

[0052] Furthermore, the spraying flip cover 304 is installed on the top of the installation groove 3017. A rotating shaft 3044 is arranged on the side end surface of the spraying flip cover 304, and a torsion spring 3045 is arranged on the rotating shaft 3044. The spraying flip cover 304 is rotationally connected to the sliding frame 301 through the cooperation of the rotating shaft 3044 and the torsion spring 3045.

[0053] The spraying flip cover 304 covers the installation groove 3017, thus preventing foreign objects in the digestive tract from accumulating in the installation groove 3017 and affecting the normal unfolding of the cleaning tongue 305. And the spraying flip cover 304 can keep in contact with the cleaning tongue 305 under the reset action of the torsion spring 3045, so that when spraying, it can wash the cleaning tongue 305, facilitating the next washing of the spraying tongue.

[0054] Furthermore, an arc-shaped water supply hole 3014 is arranged on the side wall of the water storage cavity 3015. A water supply channel 3041 is arranged inside the spraying flip cover 304. A water supply interface 3042 is arranged at the end of the water supply channel 3041 close to the water supply hole. A second spray head 3043 is arranged at the end of the water supply channel 3041 away from the principle of the spraying flip cover 304. The section of the spraying flip cover 304 close to the rotating shaft 3044 is a cylindrical structure fitting the arc-shaped water supply hole 3014.

[0055] When the spray flap 304 closes under the action of the torsion spring 3045, the water supply interface 3042 is misaligned with the arc-shaped water supply hole 3014, and water flow will not enter the water supply channel 3041. When the spray flap 304 is lifted by the cleaning tongue 305, the water supply interface 3042 is aligned with the arc-shaped water supply hole 3014, and water flow enters the water supply channel 3041 from the water supply interface 3042 and is finally ejected from the second nozzle 3043. At this time, the cleaning tongue 305 just unfolds, and the second nozzle 3043 flushes its surface to wash away the foreign matter scraped by it, facilitating the next unfolding for cleaning the lens.

[0056] Embodiment 2

[0057] Please refer to Figures 1 - 12 , a method for using an ultrasonic endoscope for detecting the digestive tract wall, comprising the following steps:

[0058] Step 1: Connect the probe body 1 to the connecting wire 2, ensuring that the connection is tight and stable to avoid loosening during subsequent operations and affecting the detection. The connecting wire 2 includes a main wire 201, a first expansion hole 202, a first auxiliary data line 203, a second auxiliary data line 204, a water flow hole 205, and an air flow hole 206. When connecting, attention should be paid to the corresponding relationship of each line and channel to ensure correct connection. Connect the connected probe body 1 to the detection device, check whether the communication between the devices is normal, and confirm whether each function can be started normally, such as whether the ultrasonic probe 101, the camera 102, the fill light 103, etc. can work normally;

[0059] Step 2: Slowly insert the assembled ultrasonic endoscope into the digestive tract. The operation process should be gentle and stable to avoid damaging the digestive tract wall. Obtain ultrasonic images of the digestive tract wall through the ultrasonic probe 101, and use the camera 102 to observe the internal situation of the digestive tract in real time. The fill light 103 provides sufficient illumination so that the doctor can clearly see the condition inside the digestive tract for accurate detection and diagnosis;

[0060] Step 3: When it is necessary to clean the camera 102, supply water to the probe body 1 through the water flow hole 205 of the connecting wire 2. The water flow enters the sliding groove 105, the pressure in the sliding groove 105 increases, causing the sliding frame 301 to squeeze the elastic ring 302 and slide outwards, and the first nozzle 303 is exposed. The first nozzles 303 are evenly installed in the dark grooves 3016 on the side end face of the sliding frame 301, and the water spraying direction is towards the camera 102 to flush the lens at the front end of the camera 102 to remove the attached digestive tract mucus;

[0061] During the flushing process, if further cleaning is required, high-pressure air is intermittently introduced into the air supply pipe 3052. The air flow enters the air supply pipe 3052 through the air inlet hole 3012 in the sliding frame 301 and then enters the cleaning tongue 305. The cleaning tongue 305 is a spiral hollow silica gel roll. Under the action of air pressure, it unfolds outward and extends towards the camera 102 end. During the unfolding process, several raised triangular silica gel ridges of the elastic scraping blades 30512 uniformly arranged on the outer end face of the cleaning tongue 305 wipe the dirt on the front lens of the camera 102. At the same time, the pressure relief port 30511 at the end of the cleaning tongue 305 continuously sprays high-pressure air to blow the surface of the lens, improving the cleaning effect. During the unfolding process of the cleaning tongue 305, it will lift the spray flip cover 304. The spray flip cover 304 is installed at the top of the installation groove 3017 and is rotatably connected to the sliding frame 301 through the rotating shaft 3044 and the torsion spring 3045. When the spray flip cover 304 is lifted, its water supply interface 3042 is aligned with the arc-shaped water supply hole 3014 on the side wall of the water storage cavity 3015. The water flow enters the water supply channel 3041 from the water supply interface 3042 and finally sprays out from the second spray head 3043 to flush the surface of the unfolded cleaning tongue 305 and wash down the scraped foreign objects;

[0062] Step 4: After the detection and cleaning are completed, slowly take out the probe body 1, pay attention to avoid colliding with and damaging the equipment, disassemble the probe body 1 from the equipment, and carefully clean each component.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
