Description

Technical Field

[0001] This invention relates to the field of gastroscopy technology, specifically to an integrated gastroscopy device and method that combines detection, sampling, and treatment. Background Technology

[0002] Gastroscopy is a medical examination method, and also refers to the instrument used in this examination. It uses a thin, flexible tube inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum. Especially for small lesions, gastroscopy can directly observe the true condition of the examined area. Furthermore, by performing pathological biopsies and cytological examinations on suspicious lesions, a definitive diagnosis can be made. It is the preferred examination method for upper gastrointestinal tract lesions. Currently used medical endoscopes generally use a black plastic tube about one centimeter in diameter. The end of the tube has a lens and a light source. It is inserted into the patient to observe the esophagus, stomach, duodenum, etc. to examine the condition of the stomach. This type of existing endoscope only has the function of sampling, and cannot simultaneously take into account the technical effect of applying medicine to the lesions in the patient's stomach. It has a single function and strong limitations. Summary of the Invention

[0006] In a preferred embodiment of the present invention, a piston head is fixedly connected to the end of the telescopic rod away from the clamp.

The multiple rope-tying rods are arranged in a circumferential array. The ends of the multiple rope-tying rods away from the telescopic rod are respectively fixedly connected to the ends of the multiple tension ropes away from the gates.

[0007] As a preferred embodiment of the present invention, each of the plurality of tension ropes is surrounded by an arc-shaped spring, which is located inside the sliding cavity.

[0008] As a preferred embodiment of the present invention, a return spring is sleeved around the telescopic rod. The return spring is located on the side of the telescopic sleeve away from the clamp and is fixedly connected to the telescopic sleeve. The end of the return spring away from the telescopic sleeve abuts against the outer wall of a plurality of rope-tying rods.

[0009] In a preferred embodiment of the present invention, the drug delivery assembly includes an elastic balloon bag, which is fixedly connected to the outer wall of the central tube. An elastic drug delivery bag is fixedly provided around the elastic balloon bag and is also fixedly connected to the outer wall of the central tube. The outer wall of the elastic drug delivery bag has multiple drug delivery holes. A through hole is provided on the outer wall of the central tube. A solenoid valve is fixedly provided on the inner wall of the central tube and is located around the opening of the through hole. A partition plate is fixedly connected to the inner wall of the central tube. An air guide tube is fixedly connected to the side of the partition plate away from the solenoid valve. The air guide tube passes through one end of the central tube, and a flexible air tube is fixedly connected to the end of the air guide tube away from the partition plate.

[0010] As a preferred embodiment of the present invention, a drug dispensing port is provided through the inner wall of the central tube. The drug dispensing port is located on the side of the partition plate away from the solenoid valve. Multiple drug dispensing ports are connected to the elastic drug dispensing bag. A drug injection hole is provided through the side of the central tube away from the sampling component. A soft drug delivery tube is fixedly connected to the side of the central tube away from the sampling component. The soft drug delivery tube is located around the opening of the drug injection hole.

[0011] As a preferred embodiment of the present invention, a plurality of elastic ribs are fixedly connected to the outer wall of the elastic balloon bag, the plurality of elastic ribs are distributed in a circumferential array, and the side of the plurality of elastic ribs away from the elastic balloon bag is fixedly connected to the inner wall of the elastic drug-filled bag.

[0012] As a preferred embodiment of the present invention, a camera is fixedly connected to the outer wall of the ball head, and the camera is located between multiple liquid-dipping holes.

[0013] An integrated gastroscopy device that combines detection, sampling, and treatment includes the following steps for use: S1. Connect the flexible trachea to the output end of the air supply unit of the external gastroscopy device, and connect the flexible drug delivery tube to the drug output end of the external gastroscopy device. S2. In the initial state, both the elastic balloon bag and the elastic drug delivery bag are empty and deflated. Therefore, the inner wall of the elastic balloon bag will be tightly attached to the outer wall of the central catheter, and the inner wall of the elastic drug delivery bag will be tightly attached to the outer wall of the elastic balloon bag. The doctor inserts the central catheter, sampling component, and drug delivery component into the patient's stomach through the patient's mouth. At the same time, the camera captures video and transmits it to the endoscope display screen to facilitate accurate operation by the doctor. The camera also captures the condition of the ulcer inside the patient's stomach to facilitate diagnosis by the doctor. S3. Activate the external endoscope. The endoscope introduces compressed gas into the soft trachea. The compressed gas is discharged into the central tube through the air tube. As the volume of compressed gas inside the central tube increases, the gas pressure inside the central tube gradually increases, pushing the piston head towards the end closer to the ball head. The movement of the piston head drives the telescopic rod to move synchronously, causing the telescopic rod to slide along the inner wall of the telescopic sleeve and move the clamp together. During this process, the return spring is compressed and stores energy. The movement of the clamp causes the clamped sampling sponge ball to move closer to multiple liquid-absorbing holes until the outer wall of the sampling sponge ball abuts against the inner wall of the ball head. At the same time, the movement of the telescopic rod also drives multiple binding rods to move together. The movement of multiple binding rods pulls multiple tension ropes, causing the tension ropes to pull the gate to slide along the inner wall of the sliding cavity. During this process, the arc spring is compressed and stores energy, causing multiple liquid-absorbing holes to open. At this time, the patient's gastric fluid enters the interior of the ball head through multiple liquid-absorbing holes and is absorbed by the sampling sponge ball, thus sampling the patient's gastric fluid. S4. After sampling, turn off the gas supply to the external gastroscope and open the solenoid valve. The return force of the reset spring drives multiple binding rods and telescopic rods to reset. At the same time, multiple arc springs are released elastically, pushing multiple gates to slide and reset along the inner wall of multiple sliding cavities, and sealing multiple dipping holes again to prevent subsequent treatment drugs from entering the interior of the bulb through multiple dipping holes and affecting the gastric fluid dipped on the sampling sponge. S5. After multiple gates are completely closed, the gas supply unit of the endoscope is restarted. At this time, compressed air is discharged into the interior of the central tube through the air guide tube. Compressed gas is then discharged into the interior of the elastic balloon bag through the solenoid valve, causing the gas volume inside the deflated elastic balloon bag to gradually increase, thus inflating the elastic balloon bag. Since the elastic force of the elastic balloon bag is less than that of the return spring, the gas delivered into the elastic balloon bag will not push the piston head. When the elastic balloon bag inflates to the point of contact with the patient's gastric mucosa, the solenoid valve and the gas supply unit of the external endoscope are closed, and the drug delivery unit of the endoscope is turned on. The medication is delivered into the interior of the central tube through the soft drug delivery tube and then into the space between the elastic balloon bag and the elastic drug delivery bag through multiple drug delivery ports. It is then delivered into the patient's stomach through multiple drug delivery holes. Because the outer wall of the elastic drug delivery bag is in contact with the patient's gastric mucosa, the medication delivered through the multiple drug delivery holes can be more evenly coated on the patient's gastric wall, ensuring the treatment effect. S6. After the patient's stomach medication is administered, turn off the medication delivery unit of the endoscope and disconnect the soft endotracheal tube from the output end of the air supply unit. Then, open the solenoid valve to depressurize the inside of the elastic balloon bag, thus restoring it to its initial state and making it close to the outer wall of the central tube, facilitating its removal from the patient's stomach. Afterward, the doctor unscrews the bulb from the end of the central tube and uses medical forceps to remove the sampling sponge ball soaked in gastric fluid from inside the clamp. The gastric fluid collected on the sampling sponge ball is then subjected to medical testing.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the volume of compressed gas inside the central tube continuously increases, causing the gas pressure inside the central tube to gradually increase. This pushes the piston head to move towards the end closer to the ball head. The movement of the piston head drives the telescopic rod to move synchronously, causing the telescopic rod to slide along the inner wall of the telescopic sleeve and move the clamp together. During this process, the return spring is compressed and stores energy. The movement of the clamp causes the clamped sampling sponge ball to move closer to multiple liquid-dipping holes until the outer wall of the sampling sponge ball abuts against the inner wall of the ball head. At the same time, the movement of the telescopic rod also drives multiple binding rope rods to move together. The movement of multiple binding rope rods pulls multiple tension ropes, causing the tension ropes to pull the gate to slide along the inner wall of the sliding cavity. During this process, the arc spring is compressed and stores energy, causing multiple liquid-dipping holes to open. At this time, the patient's gastric fluid enters the interior of the ball head through multiple liquid-dipping holes and is dipped by the sampling sponge ball to sample the patient's gastric fluid.

[0015] 2. In this invention, after sampling is completed, the gas supply to the external gastroscope is turned off and the solenoid valve is opened. The rebound force of the reset spring drives multiple binding rods and telescopic rods to reset. At the same time, multiple arc springs are elastically released, pushing multiple gates to slide and reset along the inner wall of multiple sliding cavities, thereby sealing multiple dipping holes again, preventing subsequent treatment drugs from entering the interior of the bulb through multiple dipping holes and affecting the gastric fluid dipped on the sampling sponge.

[0016] 3. In this invention, compressed air is supplied to the centrally placed tube via the gas supply unit of the endoscope through the air guide tube. At this time, the compressed gas is discharged into the elastic balloon bag through the solenoid valve, causing the gas volume inside the deflated elastic balloon bag to gradually increase, thus inflating the elastic balloon bag. Since the elastic force of the elastic balloon bag is less than that of the return spring, the gas delivered into the elastic balloon bag will not push the piston head. When the elastic balloon bag inflates to the point of contact with the patient's gastric mucosa, the solenoid valve and the gas supply unit of the external endoscope are closed, and the drug delivery unit of the endoscope is opened. The drug is introduced into the centrally placed tube through the soft drug delivery tube and introduced between the elastic balloon bag and the elastic drug delivery bag through multiple drug delivery ports. Then, it is delivered into the patient's stomach through multiple drug delivery holes. Since the outer wall of the elastic drug delivery bag is in contact with the patient's gastric mucosa, the drug delivered through the multiple drug delivery holes can be more evenly coated on the patient's gastric wall, ensuring the therapeutic effect.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-8 The present invention provides a technical solution, specifically including the following embodiments: Example 1, see details below. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, an integrated gastroscopy device for detection, sampling, and treatment includes a central tube 1. One end of the central tube 1 is detachably connected to a sampling component 2 via a thread. The sampling component 2 is used for gastric fluid sampling. A medication delivery component 3 is fixedly provided on the outer wall of the central tube 1. The medication delivery component 3 is used for administering medication to the stomach. A partition plate 101 is fixedly connected to the inner wall of the central tube 1. A duct tube 102 is fixedly connected to the side of the partition plate 101 away from the solenoid valve 4. The duct tube 102 passes through one end of the central tube 1. A flexible trachea 105 is fixedly connected to the end of the duct tube 102 away from the partition plate 101. The sampling component 2 includes a ball head 201, which is hemispherical. Multiple liquid-dipping holes 202 are formed through the outer wall of the ball head 201 away from the central tube 1. Multiple sliding cavities 203 are formed inside the ball head 201 and are arranged in a circumferential array. A gate plate 204 is slidably connected inside each of the multiple sliding cavities 203. The gate plates 204 are located around the multiple liquid-dipping holes 202. Multiple support frames 205 are fixedly connected to the inner wall of the ball head 201 and are arranged in a circumferential array. The abutting ends of the multiple support frames 205 are connected to a telescopic sleeve 206. A telescopic rod 207 is slidably connected to the inner wall of the telescopic sleeve 206. A clamp 208 is fixedly connected to one end of the telescopic rod 207 near the multiple gate plates 204. A sampling sponge ball 209 is clamped inside the clamp 208. The position of the sampling sponge ball 209 corresponds to the position of the multiple liquid-dipping holes 202. A piston head 2016 is fixedly connected to the end of the telescopic rod 207 away from the clamp 208. The outer wall of the piston head 2016 is slidably connected to the inner wall of the central tube 1. Tension ropes 2012 are fixedly connected to the ends of multiple gates 204 that are far apart from each other. Multiple rope-threading grooves 2010 are provided inside the ball head 201, and these grooves communicate with the interior of the sliding cavity 203. Multiple rope-leading holes 2011 are provided on the inner wall of the ball head 201, and multiple tension ropes 2012... 012 passes through the rope groove 2010 and the rope hole 2011 respectively, and extends into the interior of the ball head 201. The multiple rope holes 2011 are respectively connected to the multiple rope grooves 2010. Multiple rope binding rods 2014 are fixedly connected to the outer wall of the telescopic rod 207. The multiple rope binding rods 2014 are arranged in a circumferential array. The ends of the multiple rope binding rods 2014 away from the telescopic rod 207 are respectively fixedly connected to the ends of the multiple tension ropes 2012 away from the gate plate 204. More specifically, compressed gas is introduced into the soft trachea 105 via a gastroscopy device. The compressed gas is then discharged into the centrally inserted tube 1 through the air guide tube 102. As the volume of compressed gas inside the centrally inserted tube 1 increases, the gas pressure inside the centrally inserted tube 1 gradually increases, thereby pushing the piston head 2016 to move towards the end closer to the ball head 201. The movement of the piston head 2016 causes the telescopic rod 207 to move synchronously, causing the telescopic rod 207 to slide along the inner wall of the telescopic sleeve 206, which in turn moves the clamp 208. During this process, the return spring 2015 is compressed and stores energy, and the movement of the clamp 208 moves the sampled sponge ball 20 that is clamped. 9 moves closer to the multiple dipping holes 202 until the outer wall of the sampling sponge ball 209 abuts against the inner wall of the ball head 201. At the same time, the telescopic rod 207 moves along with multiple rope rods 2014. The movement of the rope rods 2014 pulls multiple tension ropes 2012, causing the tension ropes 2012 to pull the gate 204 to slide along the inner wall of the sliding cavity 203. During this period, the arc spring 2013 is compressed and stores energy, causing the multiple dipping holes 202 to open. At this time, the patient's gastric fluid enters the interior of the ball head 201 through the multiple dipping holes 202 and is picked up by the sampling sponge ball 209 to sample the patient's gastric fluid.

[0021] Example 2, see details below. Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the drug delivery component 3 includes an elastic balloon bag 301, which is fixedly connected to the outer wall of the central tube 1. An elastic drug delivery bag 302 is fixedly provided around the elastic balloon bag 301. The elastic drug delivery bag 302 is fixedly connected to the outer wall of the central tube 1. Multiple drug delivery holes 3002 are opened on the outer wall of the elastic drug delivery bag 302. A through hole is opened on the outer wall of the central tube 1. A solenoid valve 4 is fixedly provided on the inner wall of the central tube 1. The solenoid valve 4 is located outside the opening of the through hole. A drug delivery port 103 is provided through the inner wall of the central tube 1. The drug delivery port 103 is located on the side of the partition plate 101 away from the solenoid valve 4. Multiple drug delivery ports 103 are connected to the elastic drug delivery bag 302. A drug injection hole 104 is provided through the side of the central tube 1 away from the sampling component 2. A soft drug delivery tube 106 is fixedly connected to the side of the central tube 1 away from the sampling component 2. The soft drug delivery tube 106 is located around the opening of the drug injection hole 104. More specifically, after sampling, the solenoid valve 4 is opened, activating the gas supply unit of the endoscope. Compressed air is then discharged into the central tube 1 through the air guide tube 102, and compressed gas is discharged into the elastic balloon bag 301 through the solenoid valve 4. This causes the gas volume inside the initially deflated elastic balloon bag 301 to gradually increase, thus inflating the elastic balloon bag 301. Since the elastic force of the elastic balloon bag 301 is less than the elastic force of the return spring 2015, the gas being delivered into the elastic balloon bag 301 does not push the piston head 2016. However, when the elastic balloon bag 301... When the balloon expands to contact the patient's gastric mucosa, the solenoid valve 4 and the air supply unit of the external endoscope are closed, and the drug delivery unit of the endoscope is turned on. The drug is introduced into the interior of the central tube 1 through the soft drug delivery tube 106, and is introduced between the elastic balloon bag 301 and the elastic drug delivery bag 302 through multiple drug delivery ports 103. Then, it is delivered into the patient's stomach through multiple drug delivery holes 3002. Since the outer wall of the elastic drug delivery bag 302 is in contact with the patient's gastric mucosa, the drug delivered through the multiple drug delivery holes 3002 can be more evenly coated on the patient's stomach wall, ensuring the treatment effect.

[0022] Example 3, see details below. Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, multiple tension ropes 2012 are all surrounded by arc springs 2013, which are located inside the sliding cavity 203.

[0023] A return spring 2015 is sleeved around the telescopic rod 207. The return spring 2015 is located on the side of the telescopic sleeve 206 away from the clamp 208 and is fixedly connected to the telescopic sleeve 206. The end of the return spring 2015 away from the telescopic sleeve 206 abuts against the outer wall of the multiple rope-tying rods 2014. Furthermore, after sampling is completed, the gas supply to the external endoscope is turned off, and the solenoid valve 4 is opened. The rebound force of the reset spring 2015 drives the multiple binding rods 2014 and telescopic rods 207 to reset. At the same time, the multiple arc springs 2013 are elastically released, pushing the multiple gates 204 to slide and reset along the inner wall of the multiple sliding cavities 203, and sealing the multiple dipping holes 202 again to prevent subsequent treatment drugs from entering the interior of the ball head 201 through the multiple dipping holes 202 and affecting the gastric fluid dipped on the sampling sponge ball 209.

[0024] Multiple elastic ribs 303 are fixedly connected to the outer wall of the elastic balloon bag 301. The multiple elastic ribs 303 are arranged in a circumferential array. The side of the multiple elastic ribs 303 away from the elastic balloon bag 301 is fixedly connected to the inner wall of the elastic drug-filled bag 302. Furthermore, by setting multiple elastic ribs 303 to connect the elastic balloon bag 301 and the elastic drug-filled bag 302, the connection effect between the elastic drug-filled bag 302 and the elastic balloon bag 301 is ensured.

[0025] A camera 5 is fixedly connected to the outer wall of the ball head 201, and the camera 5 is located between multiple liquid-dipping holes 202; Furthermore, the video is captured by camera 5 and transmitted to the endoscope display screen, facilitating accurate operation by the doctor. At the same time, camera 5 captures the condition of the patient's internal gastric ulcers, making it easier for the doctor to diagnose.

[0026] An integrated gastroscopy device that combines detection, sampling, and treatment includes the following steps for use: S1. Connect the flexible trachea 105 to the output end of the air supply unit of the external gastroscopy instrument, and connect the flexible drug delivery tube 106 to the drug output end of the external gastroscopy instrument. S2. In the initial state, both the elastic balloon bag 301 and the elastic drug-filled bag 302 are in an empty and deflated state. Therefore, the inner wall of the elastic balloon bag 301 will be in close contact with the outer wall of the central tube 1, and the inner wall of the elastic drug-filled bag 302 will be in close contact with the outer wall of the elastic balloon bag 301. The doctor inserts the central tube 1, the sampling component 2 and the drug delivery component 3 into the patient's stomach through the patient's mouth. At the same time, the camera 5 captures video and transmits it to the endoscope display screen to facilitate the doctor's accurate operation. The camera 5 also captures the condition of the ulcer inside the patient's stomach to facilitate the doctor's diagnosis. S3. The external endoscope is activated, and compressed gas is introduced into the soft trachea 105. The compressed gas is discharged into the central tube 1 through the air guide tube 102. As the volume of compressed gas inside the central tube 1 increases, the gas pressure inside the central tube 1 gradually increases, which in turn pushes the piston head 2016 to move towards the end closer to the ball head 201. The movement of the piston head 2016 causes the telescopic rod 207 to move synchronously, so that the telescopic rod 207 slides along the inner wall of the telescopic sleeve 206, causing the clamp 208 to move together. During this process, the return spring 2015 is compressed and stored, and the movement of the clamp 208 causes the sampled sponge ball that is clamped to move. 209 moves closer to the multiple dipping holes 202 until the outer wall of the sampling sponge ball 209 abuts against the inner wall of the ball head 201. At the same time, when the telescopic rod 207 moves, it also drives the multiple binding rope rods 2014 to move together. The movement of the multiple binding rope rods 2014 will pull the multiple tension ropes 2012, thereby causing the tension ropes 2012 to pull the gate 204 to slide along the inner wall of the sliding cavity 203. During this period, the arc spring 2013 is compressed and stored, causing the multiple dipping holes 202 to open. At this time, the patient's gastric fluid enters the interior of the ball head 201 through the multiple dipping holes 202 and is dipped by the sampling sponge ball 209 to sample the patient's gastric fluid. S4. After sampling is completed, the gas supply to the external gastroscope is turned off and the solenoid valve 4 is opened. The rebound force of the reset spring 2015 drives the multiple binding rods 2014 and telescopic rods 207 to reset. At the same time, the multiple arc springs 2013 are elastically released, pushing the multiple gates 204 to slide and reset along the inner wall of the multiple sliding cavities 203, and sealing the multiple dipping holes 202 again to prevent subsequent treatment drugs from entering the interior of the ball head 201 through the multiple dipping holes 202 and affecting the gastric fluid dipped on the sampling sponge ball 209. S5. After multiple gates 204 are completely closed, the gas supply unit of the endoscope is restarted. At this time, compressed air is discharged into the interior of the central tube 1 through the air guide tube 102. The compressed gas is then discharged into the interior of the elastic balloon bag 301 through the solenoid valve 4, causing the amount of gas inside the deflated elastic balloon bag 301 to gradually increase, thus inflating the elastic balloon bag 301. However, the elastic force of the elastic balloon bag 301 is less than the elastic force of the return spring 2015. When the gas is delivered into the elastic balloon bag 301, it will not push the piston head 2016. When the elastic balloon bag 301... When the balloon expands to contact the patient's gastric mucosa, the solenoid valve 4 and the air supply unit of the external gastroscopy instrument are closed, and the drug delivery unit of the gastroscopy instrument is turned on. The drug is introduced into the interior of the central tube 1 through the soft drug delivery tube 106, and is introduced between the elastic balloon bag 301 and the elastic drug delivery bag 302 through multiple drug delivery ports 103. Then, it is delivered into the patient's stomach through multiple drug delivery holes 3002. Since the outer wall of the elastic drug delivery bag 302 is in contact with the patient's gastric mucosa, the drug delivered by the multiple drug delivery holes 3002 can be more evenly coated on the patient's stomach wall, ensuring the treatment effect. S6. After the patient's stomach medication is administered, the endoscope's medication delivery unit is turned off. At the same time, the flexible endotracheal tube 105 is separated from the output end of the air supply unit. Then, the solenoid valve 4 is opened, and the internal pressure of the elastic balloon bag 301 is released, thus restoring it to its initial state and tightly adhering to the outer wall of the central tube 1, making it easy to remove it from the patient's stomach. Afterward, the doctor unscrews the ball head 201 from the end of the central tube 1 and uses medical forceps to remove the sampling sponge ball 209 soaked in gastric fluid from inside the clamp 208. Then, the gastric fluid soaked in the sampling sponge ball 209 is subjected to medical testing.

[0027] This solution provides an integrated gastroscopy device that combines detection, sampling, and treatment. When in operation, the flexible trachea 105 is connected to the output end of the air supply unit of the external gastroscopy instrument, and the flexible drug delivery tube 106 is connected to the drug output end of the external gastroscopy instrument. In the initial state, both the elastic balloon bag 301 and the elastic drug-filled bag 302 are empty and deflated. Therefore, the inner wall of the elastic balloon bag 301 will be tightly attached to the outer wall of the central tube 1, and the inner wall of the elastic drug-filled bag 302 will be tightly attached to the outer wall of the elastic balloon bag 301. The doctor inserts the central tube 1, the sampling component 2, and the drug delivery component 3 into the patient's stomach through the patient's mouth. At the same time, the camera 5 captures video and transmits it to the endoscope display screen to facilitate accurate operation by the doctor. The camera 5 also captures the condition of the ulcer inside the patient's stomach to facilitate diagnosis by the doctor. The external endoscope is activated, and compressed gas is introduced into the soft trachea 105. The compressed gas is discharged into the central tube 1 through the air guide tube 102. As the volume of compressed gas inside the central tube 1 increases, the gas pressure inside the central tube 1 gradually increases, which in turn pushes the piston head 2016 to move closer to the ball head 201. The movement of the piston head 2016 causes the telescopic rod 207 to move synchronously, so that the telescopic rod 207 slides along the inner wall of the telescopic sleeve 206, causing the clamp 208 to move together. During this process, the return spring 2015 is compressed and stored, and the movement of the clamp 208 causes the sampled sponge ball 2 to be clamped. 09 moves closer to the multiple dipping holes 202 until the outer wall of the sampling sponge ball 209 abuts against the inner wall of the ball head 201. At the same time, when the telescopic rod 207 moves, it also drives the multiple binding rope rods 2014 to move together. The movement of the multiple binding rope rods 2014 will pull the multiple tension ropes 2012, thereby causing the tension ropes 2012 to pull the gate 204 to slide along the inner wall of the sliding cavity 203. During this period, the arc spring 2013 is compressed and stored, causing the multiple dipping holes 202 to open. At this time, the patient's gastric fluid enters the interior of the ball head 201 through the multiple dipping holes 202 and is dipped by the sampling sponge ball 209 to sample the patient's gastric fluid. After sampling, the gas supply to the external gastroscope is turned off, and the solenoid valve 4 is opened. The rebound force of the reset spring 2015 drives multiple binding rods 2014 and telescopic rods 207 to reset. At the same time, multiple arc springs 2013 are elastically released, pushing multiple gates 204 to slide and reset along the inner wall of multiple sliding cavities 203, and sealing multiple dipping holes 202 again to prevent subsequent treatment drugs from entering the interior of the ball head 201 through multiple dipping holes 202 and affecting the gastric fluid dipped on the sampling sponge ball 209. After multiple gates 204 are completely closed, the gas supply unit of the endoscope is restarted. At this time, compressed air is discharged into the interior of the central tube 1 through the air guide tube 102. The compressed gas is then discharged into the interior of the elastic balloon bag 301 through the solenoid valve 4, causing the amount of gas inside the deflated elastic balloon bag 301 to gradually increase, thus inflating the elastic balloon bag 301. However, the elastic force of the elastic balloon bag 301 is less than the elastic force of the return spring 2015. When gas is delivered into the elastic balloon bag 301, it does not push the piston head 2016. When the elastic balloon bag 301 inflates... When the balloon reaches contact with the patient's gastric mucosa, the solenoid valve 4 and the air supply unit of the external gastroscopy instrument are closed, and the drug delivery unit of the gastroscopy instrument is turned on. The drug is introduced into the interior of the central tube 1 through the soft drug delivery tube 106, and is introduced between the elastic balloon bag 301 and the elastic drug delivery bag 302 through multiple drug delivery ports 103. Then, it is delivered into the patient's stomach through multiple drug delivery holes 3002. Since the outer wall of the elastic drug delivery bag 302 is in contact with the patient's gastric mucosa, the drug delivered by the multiple drug delivery holes 3002 can be more evenly coated on the patient's stomach wall, ensuring the treatment effect. After the patient's stomach medication is administered, the endoscope's delivery unit is turned off, and the flexible endotracheal tube 105 is separated from the output end of the air supply unit. Then, the solenoid valve 4 is opened, and the internal pressure of the elastic balloon bag 301 is released, thus returning it to its initial state and tightly adhering to the outer wall of the central tube 1, making it easy to remove from the patient's stomach. Afterward, the doctor unscrews the ball head 201 from the end of the central tube 1 and uses medical forceps to remove the sampling sponge ball 209 soaked in gastric fluid from inside the clamp 208. The gastric fluid soaked in the sampling sponge ball 209 is then subjected to medical testing.

A camera (5) is fixedly connected to the outer wall of the ball head (201). The camera (5) is located between multiple liquid-dispensing holes (202). The following usage steps are included: S1. Connect the soft trachea (105) to the output end of the air supply unit of the external gastroscopy instrument, and connect the soft drug delivery tube (106) to the drug output end of the external gastroscopy instrument. S2. In the initial state, both the elastic balloon bag (301) and the elastic drug-filled bag (302) are empty and deflated. Therefore, the inner wall of the elastic balloon bag (301) will be in close contact with the outer wall of the central tube (1), and the inner wall of the elastic drug-filled bag (302) will be in close contact with the outer wall of the elastic balloon bag (301). The doctor will insert the central tube (1), the sampling component (2) and the drug-filling component (3) into the patient's stomach through the patient's mouth. At the same time, the camera (5) will capture the video and transmit it to the endoscope display screen to facilitate the doctor's accurate operation. At the same time, the camera (5) will capture the patient's internal gastric ulcer condition to facilitate the doctor's diagnosis. S3. Start the external endoscope. The endoscope inputs compressed gas into the soft trachea (105). The compressed gas is discharged into the central tube (1) through the air guide tube (102). As the volume of compressed gas inside the central tube (1) increases, the gas pressure inside the central tube (1) gradually increases, which pushes the piston head (2016) to move closer to the ball head (201). The movement of the piston head (2016) drives the telescopic rod (207) to move synchronously, so that the telescopic rod (207) slides along the inner wall of the telescopic sleeve (206) and drives the clamp (208) to move together. During this period, the return spring (2015) is compressed and stored. The movement of the clamp (208) drives the sampled sponge ball (201) that is clamped to move. 09) Approach the multiple dipping holes (202) until the outer wall of the sampling sponge ball (209) abuts against the inner wall of the ball head (201). At the same time, when the telescopic rod (207) moves, it also drives multiple binding rods (2014) to move together. The movement of multiple binding rods (2014) will pull multiple tension ropes (2012), thereby causing the tension ropes (2012) to pull the gate (204) to slide along the inner wall of the sliding cavity (203). During this period, the arc spring (2013) is compressed and stored, causing multiple dipping holes (202) to open. At this time, the patient's gastric fluid enters the interior of the ball head (201) through multiple dipping holes (202) and is dipped by the sampling sponge ball (209) to sample the patient's gastric fluid. S4. After sampling, turn off the gas supply to the external gastroscope and open the solenoid valve (4). The rebound force of the reset spring (2015) drives multiple binding rods (2014) and telescopic rods (207) to reset. At the same time, multiple arc springs (2013) are elastically released, pushing multiple gates (204) to slide and reset along the inner wall of multiple sliding cavities (203), and sealing multiple dipping holes (202) again to prevent subsequent treatment drugs from entering the interior of the ball head (201) through multiple dipping holes (202) and affecting the gastric fluid dipped on the sampling sponge ball (209). S5. After multiple gates (204) are completely closed, the gas supply unit of the endoscope is restarted. At this time, compressed air is discharged into the interior of the central tube (1) through the air guide tube (102). At this time, compressed gas is discharged into the interior of the elastic balloon bag (301) through the solenoid valve (4), so that the amount of gas inside the deflated elastic balloon bag (301) gradually increases, thereby causing the elastic balloon bag (301) to inflate. However, the elastic force of the elastic balloon bag (301) is less than the elastic force of the return spring (2015). When the gas is delivered into the elastic balloon bag (301), it will not have a pushing effect on the piston head (2016). When the elastic balloon bag ( 301) When the balloon expands to contact the patient's gastric mucosa, close the solenoid valve (4) and the gas supply unit of the external gastroscopy instrument, and open the drug delivery unit of the gastroscopy instrument. The drug is delivered into the interior of the central tube (1) through the soft drug delivery tube (106), and is delivered between the elastic balloon bag (301) and the elastic drug delivery bag (302) through multiple drug delivery ports (103). Then, it is delivered into the patient's stomach through multiple drug delivery holes (3002). Since the outer wall of the elastic drug delivery bag (302) is in contact with the patient's gastric mucosa, the drug delivered through the multiple drug delivery holes (3002) can be more evenly coated on the patient's stomach wall, ensuring the treatment effect. S6. After the patient has finished taking medication into their stomach, turn off the medication delivery unit of the endoscope and separate the soft trachea (105) from the output end of the gas supply unit. Then, open the solenoid valve (4) to depressurize the inside of the elastic balloon bag (301) and restore it to its initial state. It is then attached to the outer wall of the central tube (1) to facilitate its removal from the patient's stomach. After that, the doctor unscrews the ball head (201) from the end of the central tube (1) and uses medical forceps to remove the sampling sponge ball (209) soaked in gastric fluid from the inside of the clamp (208). The gastric fluid soaked in the sampling sponge ball (209) is then subjected to medical testing.
