Description

Technical Field

[0001] This invention belongs to the field of endoscopy technology, and specifically relates to a gastric dual-scope collaborative visualization diagnostic device. Background Technology

[0002] A gastroscopy is a medical endoscope used to visualize the stomach and upper digestive tract. Its front end integrates a high-definition camera and a lighting system, which can transmit dynamic images of the inside of the digestive tract in real time during the examination, enabling doctors to clearly identify various pathological changes on the mucosal surface, such as inflammation, erosion, ulcers, polyps, and tumors.

[0003] In clinical applications, gastroscopy typically completes a direct assessment of existing mucosal lesions (such as ulcers, polyps, bleeding points, or tumors) within an examination time of 5 to 15 minutes. However, since some gastric diseases (such as intermittent bleeding, drug-induced gastric mucosal damage, and functional gastroesophageal reflux disease) require long-term continuous observation for a clear diagnosis, existing gastroscopy is difficult to meet such dynamic monitoring requirements, thus affecting the applicability of gastroscopy in early identification, accurate assessment, and efficacy tracking. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, namely that some gastric diseases (such as intermittent bleeding, drug-induced gastric mucosal damage, and functional gastroesophageal reflux disease) require long-term continuous observation for accurate diagnosis, making it difficult for existing gastroscopes to meet such dynamic monitoring requirements, this invention provides a gastric dual-endoscopic collaborative visualization diagnostic device.

[0005] The device includes a capsule endoscope, a flexible endoscope, and a magnetic suction mechanism. The capsule endoscope has a reservoir for holding an adhesive solution and features an auxiliary observation mode and a continuous observation mode. The front end of the flexible endoscope is detachably connected to the capsule endoscope for transporting and releasing it to the observation position inside the stomach. The magnetic suction mechanism is configured to apply a directional magnetic force to the observation position externally to adhere the capsule endoscope to the stomach wall and trigger the reservoir to release the adhesive solution. In the auxiliary observation mode, after the flexible endoscope transports the capsule endoscope to the observation position, the magnetic suction mechanism applies a magnetic force to fix the capsule endoscope to the stomach wall and triggers the release of the adhesive solution. Subsequently, the flexible endoscope and the capsule endoscope separate, and both simultaneously acquire images of the stomach from different perspectives. In the continuous observation mode, the adhesive solution adheres and fixes the capsule endoscope to the stomach wall, and the capsule endoscope independently and continuously acquires images of the stomach until the adhesive solution becomes ineffective due to gastric juices, causing the capsule endoscope to detach from the stomach wall.

[0006] Furthermore, the capsule endoscope includes a capsule body and a fluid storage structure; the fluid storage structure includes a flexible fluid storage bladder and multiple pressurizing magnetic locators; the surface of the flexible fluid storage bladder has multiple pressure-regulating grooves, which rupture when the pressure reaches a preset threshold; the flexible fluid storage bladder and the capsule body together form the fluid storage cavity; the multiple pressurizing magnetic locators are connected to the flexible fluid storage bladder and located within the fluid storage cavity; when the flexible endoscope transports the capsule endoscope to the observation position inside the stomach, the flexible fluid storage bladder contacts the stomach wall and deforms under pressure, and then the magnetic locator drives the multiple pressurizing magnetic locators to move towards it through magnetic force, thereby causing the flexible fluid storage bladder to deform further, causing the pressure on the pressure-regulating grooves to exceed the preset threshold and rupture, thereby releasing the adhesive fluid in the fluid storage cavity.

[0007] Furthermore, the capsule endoscope also includes an elastic ring pad; the elastic ring pad is connected to the capsule body and fits against the front end of the flexible endoscope, so that the capsule body, the elastic ring pad, and the flexible endoscope together form an adsorption cavity; the flexible endoscope includes a flexible body and an aspiration structure; the aspiration structure includes an aspiration three-way valve; the flexible body includes an inflation tube; the inflation tube communicates with the adsorption cavity and partially protrudes from the outer peripheral surface of the flexible body; the aspiration three-way valve is connected in series to the protruding section of the inflation tube and communicates with an external negative pressure generating device; when the capsule endoscope is connected to the flexible endoscope, the negative pressure generating device applies negative pressure to the adsorption cavity through the aspiration three-way valve and the inflation tube to adsorb and fix the capsule endoscope to the front end of the flexible endoscope.

[0008] Furthermore, the suction structure also includes a three-way valve and a buffer airbag; the three-way valve is connected in series between the suction three-way valve and the negative pressure generating device, and is also connected to the buffer airbag; when the capsule endoscope and the flexible endoscope are separated, the three-way valve controls the adsorption chamber to be connected to the buffer airbag, so that the gas in the buffer airbag enters the adsorption chamber sequentially through the three-way valve, the suction three-way valve and the inflation tube, thereby separating the capsule endoscope and the flexible endoscope.

[0009] Furthermore, the liquid storage structure also includes a rigid guide frame; the rigid guide frame is connected to the capsule body and to the flexible liquid storage bladder, so that the capsule body, the flexible liquid storage bladder and the rigid guide frame together form the liquid storage cavity; the rigid guide frame is used to provide structural support for the flexible liquid storage bladder during the insertion of the capsule endoscope into the stomach, so as to prevent the pressure-regulating groove from accidentally rupturing during delivery.

[0010] Furthermore, the capsule endoscope also includes a limiting magnetic suction piece; an inner groove is formed on the outer surface of the capsule body; the limiting magnetic suction piece is embedded in the inner groove and is used to cooperate with the magnetic suction mechanism to fix the capsule endoscope to the stomach wall.

[0011] Furthermore, the flexible body also includes an imaging lens; the imaging lens is located at the front end of the flexible body and is used to acquire images inside the stomach; both the outer surfaces of the capsule body and the rigid guide frame are provided with process holes; the process holes are located in the image acquisition direction of the imaging lens to avoid obstructing the field of view of the imaging lens.

[0012] Furthermore, the capsule endoscope also includes a limiting pin; a limiting groove is formed on the side of the flexible body facing the capsule endoscope; one end of the limiting pin is connected to the capsule body, and the other end is slidably inserted into the limiting groove, for limiting the displacement of the capsule endoscope relative to the flexible endoscope in the non-axial direction.

[0013] Furthermore, the magnetic attraction mechanism includes an electromagnet and a positioning structure; the positioning structure is configured to drive the electromagnet to move to an external position on the patient's body surface corresponding to the observation position inside the stomach, and to make it fit against the patient's body surface to generate a directional magnetic attraction force inside the stomach.

[0014] Furthermore, the adjusting structure includes a base, a transverse slide rail, a transverse screw, a transverse support, a vertical slide rail, a vertical screw, a vertical support, a longitudinal slide rail, and a longitudinal screw; one end of the transverse slide rail is connected to the base, and the other end is slidably inserted into the transverse support; one end of the transverse screw is rotatably mounted on the base, and the other end is threaded into the transverse support; one end of the vertical slide rail is connected to the transverse support, and the other end is slidably inserted into the vertical support; one end of the vertical screw is rotatably mounted on the transverse support, and the other end is threaded into the vertical support; one end of the longitudinal slide rail is connected to the electromagnet, and the other end is slidably inserted into the vertical support; one end of the longitudinal screw is rotatably mounted on the electromagnet, and the other end is threaded into the vertical support.

[0015] The beneficial effects of this invention are:

[0016] The device includes a capsule endoscope, a flexible endoscope, and a magnetic suction mechanism. The capsule endoscope has a reservoir for holding adhesive fluid and features an auxiliary observation mode and a continuous observation mode. The front end of the flexible endoscope is detachably connected to the capsule endoscope for transporting it to the observation position inside the stomach and releasing it. The magnetic suction mechanism is configured to apply a directional magnetic force to the observation position externally to adhere the capsule endoscope to the stomach wall and trigger the release of adhesive fluid from the reservoir. In the auxiliary observation mode, after the flexible endoscope transports the capsule endoscope to the observation position, the magnetic suction mechanism applies a magnetic force to fix the capsule endoscope to the stomach wall and triggers the release of adhesive fluid. Subsequently, the flexible endoscope and the capsule endoscope separate, and both simultaneously acquire images of the stomach from different perspectives. In the continuous observation mode, the adhesive fluid adheres and fixes the capsule endoscope to the stomach wall, and the capsule endoscope independently and continuously acquires images of the stomach until the adhesive fluid becomes ineffective due to the action of gastric juice, causing the capsule endoscope to detach from the stomach wall.

[0017] In the auxiliary observation mode, the gastric dual-endoscopic collaborative visualization diagnostic device provided by the present invention delivers the capsule endoscope to the observation position via a flexible endoscope. Then, a magnetic attraction mechanism applies magnetic force to fix the capsule endoscope to the stomach wall and triggers the release of adhesive fluid. Subsequently, the flexible endoscope and the capsule endoscope separate, and the two simultaneously acquire images of the stomach from different perspectives.

[0018] In addition, when the flexible gastroscope is acquiring images inside the stomach, the magnetic attraction mechanism applies magnetic force to fix the capsule endoscope to the stomach wall, thereby improving the stability of the connection between the capsule endoscope and the stomach wall and preventing the moving flexible gastroscope from knocking the capsule endoscope off.

[0019] In continuous observation mode, the adhesive fluid adheres and fixes the capsule endoscope to the stomach wall, allowing the capsule endoscope to independently and continuously acquire images of the stomach until the adhesive fluid becomes ineffective due to the action of gastric juice, causing the capsule endoscope to detach from the stomach wall. This solves the problem that existing endoscopes cannot meet the requirements of dynamic monitoring because some gastric diseases require long-term continuous observation for accurate diagnosis.

[0020] In addition, the magnetic attraction mechanism continuously fixes the capsule endoscope to the stomach wall through magnetic attraction during the assisted observation mode, so that the adhesive liquid has enough time to fix the capsule endoscope to the stomach wall and avoids the stomach peristalsis affecting the curing of the adhesive liquid.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] The present invention provides a gastrointestinal dual-endoscopic collaborative visualization diagnostic device, including a capsule endoscope 100, a flexible endoscope 200, and a magnetic suction mechanism 300.

[0033] The following combination Figures 1-6 A detailed description of the structure and shape of the gastric endoscope-assisted visualization diagnostic device is provided:

[0034] The capsule endoscope 100 has a reservoir for holding adhesive fluid and features an auxiliary observation mode and a continuous observation mode. The front end of the flexible endoscope 200 is detachably connected to the capsule endoscope 100 for transporting the capsule endoscope 100 to the observation position inside the stomach and releasing it. The magnetic attraction mechanism 300 is configured to apply a directional magnetic attraction force to the observation position externally to attract and fix the capsule endoscope 100 to the stomach wall and trigger the release of adhesive fluid from the reservoir. In the auxiliary observation mode, after the flexible endoscope 200 transports the capsule endoscope 100 to the observation position, the magnetic attraction mechanism 300 applies a magnetic attraction force to fix the capsule endoscope 100 to the stomach wall and triggers the release of adhesive fluid. Subsequently, the flexible endoscope 200 and the capsule endoscope 100 separate, and both simultaneously acquire images of the stomach from different perspectives. In the continuous observation mode, the adhesive fluid adheres and fixes the capsule endoscope 100 to the stomach wall, and the capsule endoscope 100 independently and continuously acquires images of the stomach until the adhesive fluid becomes ineffective due to the action of gastric juice, causing the capsule endoscope 100 to detach from the stomach wall.

[0035] In this embodiment, during the auxiliary observation mode, the flexible gastroscope 200 transports the capsule endoscope 100 to the observation position. Then, the magnetic attraction mechanism 300 applies magnetic attraction to fix the capsule endoscope 100 to the stomach wall and triggers the release of adhesive fluid. Subsequently, the flexible gastroscope 200 and the capsule endoscope 100 separate, and the two simultaneously acquire images of the stomach from different perspectives.

[0036] In addition, when the flexible gastroscope 200 is acquiring images inside the stomach, the magnetic attraction mechanism 300 applies magnetic attraction to fix the capsule endoscope 100 to the stomach wall, thereby improving the stability of the connection between the capsule endoscope 100 and the stomach wall and preventing the moving flexible gastroscope 200 from knocking the capsule endoscope 100 off.

[0037] In continuous observation mode, the adhesive fluid released from the reservoir cavity adheres and fixes the capsule endoscope 100 to the stomach wall, allowing the capsule endoscope 100 to independently and continuously acquire images of the stomach until the adhesive fluid becomes ineffective due to the action of gastric juice, causing the capsule endoscope 100 to detach from the stomach wall, thus achieving long-term continuous acquisition of images of the stomach.

[0038] In addition, the magnetic attraction mechanism 300 continuously fixes the capsule endoscope 100 to the stomach wall through magnetic attraction during the auxiliary observation mode, so that the adhesive liquid has enough time to fix the capsule endoscope 100 to the stomach wall and avoids the stomach peristalsis from affecting the curing of the adhesive liquid.

[0039] In order for the magnetic attraction mechanism 300 to trigger the release of the adhesive liquid in the reservoir:

[0040] like Figures 4-5As shown, the capsule endoscope 100 includes a capsule body 110 and a liquid storage structure 120; the liquid storage structure 120 includes a flexible liquid storage sac 121 and multiple pressurizing magnetic locators 122; the surface of the flexible liquid storage sac 121 is provided with multiple pressure-regulating grooves, which rupture when the pressure reaches a preset threshold; the flexible liquid storage sac 121 and the capsule body 110 together form a liquid storage cavity; the multiple pressurizing magnetic locators 122 are connected to the flexible liquid storage sac 121 and located in the liquid storage cavity; when the flexible endoscope 200 transports the capsule endoscope 100 to the observation position in the stomach, the flexible liquid storage sac 121 contacts the stomach wall and is deformed under pressure, and then the magnetic locator 300 drives the multiple pressurizing magnetic locators 122 to move towards it through magnetic force, so as to drive the flexible liquid storage sac 121 to further deform, so that the pressure on the pressure-regulating groove exceeds the preset threshold and ruptures, thereby releasing the adhesive fluid in the liquid storage cavity.

[0041] In this embodiment, the flexible gastroscope 200 transports the capsule endoscope 100 to the observation position inside the stomach. During this process, the flexible reservoir 121 comes into contact with the stomach wall and is deformed under pressure. Then, the magnetic attraction mechanism 300 releases directional magnetic attraction force to the observation position inside the stomach. The directional magnetic attraction force drives multiple pressurized magnetic attraction plates 122 to move toward the magnetic attraction mechanism 300. The pressurized magnetic attraction plates 122 cause the flexible reservoir 121 to deform further, so that the pressure on the constant pressure groove exceeds the preset threshold and ruptures. The adhesive liquid in the reservoir cavity is released through the rupture at the constant pressure groove. The released adhesive liquid solidifies between the flexible reservoir 121 and the stomach wall.

[0042] In addition, the flexible reservoir 121 undergoes two deformations, and the deformed flexible reservoir 121 adheres to the surface of the stomach wall, thereby increasing the connection area between the flexible reservoir 121 and the stomach wall, and thus improving the connection strength between the capsule endoscope 100 and the stomach wall.

[0043] In order to make the capsule endoscope 100 detachably connected to the front end of the flexible endoscope 200 and able to be released by the flexible endoscope 200:

[0044] like Figures 2-3As shown, the capsule endoscope 100 also includes an elastic ring pad 130; the elastic ring pad 130 is connected to the capsule body 110 and fits against the front end of the flexible endoscope 200, so that the capsule body 110, the elastic ring pad 130 and the flexible endoscope 200 surround and form an adsorption cavity; the flexible endoscope 200 includes a flexible body 210 and an aspiration structure 220; the aspiration structure 220 includes an aspiration three-way valve 221; the flexible body 210 includes an inflation tube 211; the inflation tube 211 communicates with the adsorption cavity and partially protrudes from the outer peripheral surface of the flexible body 210; the aspiration three-way valve 221 is connected in series to the protruding section of the inflation tube 211 and communicates with an external negative pressure generating device; when the capsule endoscope 100 is connected to the flexible endoscope 200, the negative pressure generating device applies negative pressure to the adsorption cavity through the aspiration three-way valve 221 and the inflation tube 211 to adsorb and fix the capsule endoscope 100 to the front end of the flexible endoscope 200.

[0045] In this embodiment, when the capsule endoscope 100 is connected to the flexible endoscope 200, the suction three-way valve 221 controls the negative pressure generating device to communicate with the adsorption cavity formed by the capsule body 110, the elastic ring pad 130 and the flexible endoscope 200. Then, the negative pressure generating device drives the air in the adsorption cavity to be discharged through the suction three-way valve 221 and the air inflator 211. As the air in the adsorption cavity is discharged, a negative pressure suction is formed, and the negative pressure suction adsorbs and fixes the capsule endoscope 100 to the front end of the flexible endoscope 200.

[0046] To improve the stability during the separation process between the capsule endoscope 100 and the flexible endoscope 200:

[0047] like Figure 2 As shown, the suction structure 220 also includes a three-way valve 222 and a buffer airbag 223; the three-way valve 222 is connected in series between the suction three-way valve 221 and the negative pressure generating device, and is also connected to the buffer airbag 223; when the capsule endoscope 100 and the flexible endoscope 200 are separated, the three-way valve 222 controls the adsorption chamber to be connected to the buffer airbag 223, so that the gas in the buffer airbag enters the adsorption chamber in sequence through the three-way valve 222, the suction three-way valve 221 and the inflation tube 211, thereby separating the capsule endoscope 100 and the flexible endoscope 200.

[0048] In this embodiment, when the capsule endoscope 100 and the flexible endoscope 200 are separated, the three-way valve 222 controls the adsorption chamber to be connected to the buffer airbag 223, so that the gas in the buffer airbag enters the adsorption chamber in sequence through the three-way valve 222, the suction three-way valve 221 and the inflation tube 211, thereby gradually reducing the negative pressure suction in the adsorption chamber until it disappears, thereby separating the capsule endoscope 100 and the flexible endoscope 200.

[0049] When it is necessary to inject gas into the buffer airbag, the buffer airbag 223 is first connected to the negative pressure generating device through the three-way valve 222. The negative pressure generating device expels the air from the buffer airbag 223. Then, the three-way valve 222 and the suction three-way valve 221 work together to connect the buffer airbag 223 to the inflation tube 211. Then, the inflation tube 211 injects medical-grade gas into the buffer airbag 223.

[0050] To reduce the likelihood of the pressure-regulating grooves on the surface of the flexible reservoir 121 rupturing during delivery of the capsule endoscope 100 to the patient's stomach:

[0051] like Figures 3-5 As shown, the liquid storage structure 120 also includes a rigid guide frame 123; the rigid guide frame 123 is connected to the capsule body 110 and to the flexible liquid storage bladder 121, so that the capsule body 110, the flexible liquid storage bladder 121 and the rigid guide frame 123 together form a liquid storage cavity; the rigid guide frame 123 is used to provide structural support for the flexible liquid storage bladder 121 during the insertion of the capsule endoscope 100 into the stomach, so as to prevent the pressure groove from accidentally breaking during the delivery process.

[0052] In this embodiment, during the delivery of the capsule endoscope 100 to the patient's stomach, the capsule endoscope 100 needs to withstand axial impact and radial compression. The rigid guide frame 123 transmits the axial impact to the capsule body 110 through its own structure, thereby reducing the deformation of the flexible reservoir 121 during delivery and thus reducing the pressure on the pressure-regulating groove, thereby reducing the probability of the pressure-regulating groove on the surface of the flexible reservoir 121 rupturing during the delivery of the capsule endoscope 100 to the patient's stomach.

[0053] In order for the magnetic attraction mechanism 300 to fix the capsule endoscope 100 to the stomach wall by applying directional magnetic attraction:

[0054] like Figures 3-5 As shown, the capsule endoscope 100 also includes a limiting magnetic suction piece 140; an inner groove is provided on the outer surface of the capsule body 110; the limiting magnetic suction piece 140 is embedded in the inner groove and is used to cooperate with the magnetic suction mechanism 300 to fix the capsule endoscope 100 to the stomach wall.

[0055] In this embodiment, the magnetic attraction mechanism 300 applies a directional magnetic attraction force to the observation position inside the stomach. The directional magnetic attraction force drives the limiting magnetic attraction piece 140 to move toward the magnetic attraction mechanism 300, and the limiting magnetic attraction piece 140 drives the capsule body 110 to be fixed to the stomach wall. By providing an embedded groove on the outer surface of the capsule body 110 and embedding the limiting magnetic attraction piece 140 in the embedded groove, the influence of the limiting magnetic attraction piece 140 on the mucosa inside the body is reduced.

[0056] To ensure that the flexible endoscope 200 can deliver the capsule endoscope 100 to the observation position inside the stomach:

[0057] like Figure 3 As shown, the flexible body 210 also includes an imaging lens 212; the imaging lens 212 is located at the front end of the flexible body 210 and is used to acquire images inside the stomach; both the outer surfaces of the capsule body 110 and the rigid guide frame 123 are provided with process holes; the process holes are located in the image acquisition direction of the imaging lens 212 to avoid obstructing the field of view of the imaging lens 212.

[0058] In this embodiment, process holes are provided on the outer surfaces of both the capsule body 110 and the rigid guide frame 123, and the process holes are located in the image acquisition direction of the imaging lens 212, so as to avoid the capsule endoscope 100 from obstructing the field of view of the imaging lens 212. This allows the flexible endoscope 200 to acquire images of the stomach through the imaging lens 212, and medical personnel can control the flexible endoscope 200 to move the capsule endoscope 100 to the observation position inside the stomach by using the acquired images.

[0059] To reduce the chance of the capsule endoscope 100 and the flexible endoscope 200 detaching:

[0060] like Figures 3-5 As shown, the capsule endoscope 100 also includes a limiting pin 150; a limiting groove is formed on the side of the flexible body 210 facing the capsule endoscope 100; one end of the limiting pin 150 is connected to the capsule body 110, and the other end is slidably inserted into the limiting groove to limit the displacement of the capsule endoscope 100 relative to the flexible endoscope 200 in the non-axial direction.

[0061] In this embodiment, by inserting the limiting pin 150 connected to the capsule body 110 into the limiting groove opened on the flexible body 210, the displacement of the capsule endoscope 100 relative to the flexible endoscope 200 in the non-axial direction is limited, thereby reducing the lateral stress transmission received by the capsule endoscope 100 and reducing the probability of the capsule endoscope 100 and the flexible endoscope 200 detaching.

[0062] In order to enable the magnetic attraction mechanism 300 to apply directional magnetic attraction force to the observation position inside the stomach from outside:

[0063] like Figure 1 As shown, the magnetic attraction mechanism 300 includes an electromagnet 310 and an adjustment structure 320; the adjustment structure 320 is configured to drive the electromagnet 310 to move to an external position on the patient's body surface corresponding to the observation position inside the stomach, and to make it fit against the patient's body surface to generate a directional magnetic attraction force inside the stomach.

[0064] In this embodiment, the positioning structure 320 moves the electromagnet 310 to an external position on the patient's body surface corresponding to the observation position inside the stomach, and causes it to fit against the patient's body surface, thereby reducing the distance between the electromagnet 310 and the capsule endoscope 100, thereby reducing the loss of the magnetic attraction force generated by the electromagnet 310 during the transmission process, so that the magnetic attraction mechanism 300 applies a directional magnetic attraction force to the observation position inside the stomach from the outside.

[0065] In order to move the electromagnet 310 to an external position on the patient's body surface corresponding to the observation position inside the stomach, and to make it fit against the patient's body surface:

[0066] like Figure 1 and Figure 6 As shown, the adjustment structure 320 includes a base 321, a transverse slide rail 322, a transverse screw 323, a transverse support 324, a vertical slide rail 325, a vertical screw 326, a vertical support 327, a longitudinal slide rail 328, and a longitudinal screw 329. One end of the transverse slide rail 322 is connected to the base 321, and the other end is slidably inserted into the transverse support 324. One end of the transverse screw 323 is rotatably mounted on the base 321, and the other end is threaded into the transverse support 324. One end of the vertical slide rail 325 is connected to the horizontal support 324, and the other end is slidably inserted into the vertical support 327; one end of the vertical screw 326 is rotatably mounted on the horizontal support 324, and the other end is threaded into the vertical support 327; one end of the longitudinal slide rail 328 is connected to the electromagnet 310, and the other end is slidably inserted into the vertical support 327; one end of the longitudinal screw 329 is rotatably mounted on the electromagnet 310, and the other end is threaded into the vertical support 327.

[0067] In this embodiment, the transverse screw 323 is first rotated around its own axis. Under the threaded engagement, the transverse screw 323 drives the transverse support 324 to move along the transverse slide rail 322. The transverse support 324 drives the electromagnet 310 to move in the vertical direction of the observation position inside the stomach. Then, the vertical screw 326 is rotated around its own axis. Under the threaded engagement, the vertical screw 326 drives the vertical support 327 to move along the vertical slide rail 325. The vertical support 327 drives the electromagnet 310 to be directly in front of the observation position inside the stomach. Then, the longitudinal screw 329 is rotated around its own axis. Under the threaded engagement, the longitudinal screw 329 drives the electromagnet 310 to move. Under the constraint of the longitudinal slide rail 328, the electromagnet 310 moves towards the patient's body surface until it is in contact with the patient's body surface.

1. A gastric endoscope-assisted visual diagnostic device, characterized in that: Includes a capsule endoscope (100), a flexible endoscope (200), and a magnetic suction mechanism (300). The capsule endoscope (100) has a reservoir for containing adhesive fluid and has an auxiliary observation mode and a continuous observation mode. The front end of the flexible gastroscope (200) is detachably connected to the capsule endoscope (100) for delivering the capsule endoscope (100) to the observation position inside the stomach and releasing it; The magnetic attraction mechanism (300) is configured to apply a directional magnetic attraction force to the observation position outside the body to adsorb and fix the capsule endoscope (100) to the stomach wall and trigger the release of the adhesive liquid from the reservoir. In the auxiliary observation mode, after the flexible gastroscope (200) transports the capsule endoscope (100) to the observation position, the magnetic attraction mechanism (300) applies magnetic attraction to fix the capsule endoscope (100) to the stomach wall and triggers the release of the adhesive liquid. Then the flexible gastroscope (200) and the capsule endoscope (100) separate, and the two acquire images of the stomach from different perspectives simultaneously. In the continuous observation mode, the adhesive fluid adheres and fixes the capsule endoscope (100) to the stomach wall, and the capsule endoscope (100) independently and continuously acquires images inside the stomach until the adhesive fluid becomes ineffective due to the action of gastric juice, causing the capsule endoscope (100) to detach from the stomach wall.

2.

The liquid storage structure (120) includes a flexible liquid storage bladder (121) and multiple pressurized magnetic absorbing sheets (122). The surface of the flexible liquid storage bladder (121) is provided with a plurality of pressure-regulating grooves, which rupture when the pressure reaches a preset threshold. The flexible liquid storage bladder (121) and the capsule body (110) together form the liquid storage cavity; Multiple pressurized magnetic absorbing sheets (122) are connected to the flexible liquid storage bladder (121) and located within the liquid storage cavity; When the flexible endoscope (200) delivers the capsule endoscope (100) to the observation position inside the stomach, the flexible reservoir (121) comes into contact with the stomach wall and is deformed under pressure. Then, the magnetic attraction mechanism (300) drives multiple pressurized magnetic attraction pieces (122) to move toward it through magnetic force, so as to drive the flexible reservoir (121) to deform further, so that the pressure on the pressure groove exceeds the preset threshold and ruptures, thereby releasing the adhesive liquid in the reservoir cavity.

3. The gastric endoscope dual-scope collaborative visualization diagnostic device according to claim 2, characterized in that: The capsule endoscope (100) also includes an elastic ring pad (130).
