Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary devices, and particularly relates to an auxiliary device for gastroscopy examination in the department of gastroenterology. Background Technique

[0002] The department of gastroenterology is a clinical tertiary discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Gastroscopy can directly observe the real situation of the examined part, and can further clarify the diagnosis by performing pathological biopsy and cytological examination on suspicious lesion sites. It is the preferred examination method for upper digestive tract lesions. A gastroscope is a slender and flexible tube that is inserted into the stomach through the mouth. Doctors can directly observe the lesions of the esophagus, stomach, and duodenum, especially observe tiny lesions.

[0003] During the gastroscopy examination process, an auxiliary device is required, which usually inserts the gastroscope tube into the mouth and esophagus. For example, an auxiliary device for gastroscopy examination in the department of gastroenterology with the application number: CN202311608043.3. The present invention solves the problem that the existing auxiliary device for gastroscopy examination in the department of gastroenterology continuously provides high-intensity support to the mouth during use, affecting the observation of the mouth during intubation and causing oral discomfort after long-term use. By setting a conveying mechanism, a supporting mechanism, and a collecting mechanism, it is convenient to control the insertion and extraction operations of the gastroscope catheter through the conveying mechanism, and the supporting mechanism is driven to operate during the insertion and extraction of the gastroscope catheter, so that the support rod stably supports the mouth. When the insertion and extraction are completed, the force on the support rod weakens. At this time, the mouth can open and close to a certain extent, and the opening and closing process will drive the support rod to open and close synchronously. The gastroscope catheter will be located in the middle gap position of the support rod, thus ensuring that the gastroscope catheter will not be bitten. During the process of pulling out the gastroscope catheter, the collecting mechanism will scrape the mucus on the outer wall of the gastroscope catheter into the communication cavity, and at the same time pump the mucus in the communication cavity into the collection box for storage. This device is easy to use, can effectively ensure that the whole mouth is in an open state during the insertion and extraction of the gastroscope catheter, and there is less obstruction inside the mouth, which is convenient for medical staff to insert and extract the gastroscope catheter, improving work efficiency and facilitating use.

[0004] In practical applications, such auxiliary devices use driving wheels for the insertion and extraction operations of the gastroscope catheter. However, when the gastroscope catheter is pulled out, the mucus attached to the gastroscope catheter will adhere to the driving wheel. Since the driving wheel is located inside the housing, it is difficult to clean. During the next insertion process of the gastroscope catheter, the residual mucus on the driving wheel will contaminate the gastroscope catheter, thereby increasing the risk of patient infection.

[0005] In addition, when inserting and removing the gastroscope catheter using the driving wheel, if the surface of the driving wheel is too smooth, the gastroscope catheter may slip on the driving wheel, resulting in ineffective delivery of the gastroscope catheter; conversely, if the surface of the driving wheel is too rough, it may damage the outer wall of the gastroscope catheter, causing burrs to appear on the outer wall. These burrs may scratch the inner wall of the esophagus when entering the esophagus, leading to bleeding.

[0006] At the same time, the rubber ring used to remove mucus will come into contact with the gastroscope catheter during both the insertion and removal processes of the gastroscope catheter. This will not only contaminate the gastroscope catheter entering the human body, but also increase the friction time, thereby exacerbating the wear of the gastroscope catheter. Summary of the Invention

[0007] The purpose of the present invention is to provide an auxiliary device for gastroscope examination in the department of digestive medicine, which can improve the safety, hygiene, operation convenience and accuracy of gastroscope examination, and reduce the maintenance cost and operation time of the equipment.

[0018] In a preferred embodiment, the cleaning part includes a first round rod, which is rotatably connected to the inner walls on both sides of the housing. A cleaning roller and a first transmission gear are mounted on the first round rod. Flushing seats are also fixedly connected to the inner walls on both sides of the housing, and spray nozzles are evenly distributed on the flushing seats. A water pump is mounted on the side of the protective housing. The drainage end of the water pump is connected to a drainage pipe, and the drainage pipe communicates with the flushing seat. A hollow shell is arranged on the drainage pipe. A second round rod is rotatably connected to the hollow shell.

[0023] The technical effects achieved by the present invention are as follows:

[0024] By the forward and reverse rotation of the driving wheel, the present invention ensures the stable transmission of the gastroscope catheter during the insertion and extraction processes. During the process of driving the gastroscope catheter to move, the negative pressure part is started to generate negative pressure inside the driving wheel. The suction force generated by the through holes on the driving wheel can not only adsorb the gastroscope catheter to prevent it from slipping during the transportation process, but also suck in some mucus when the pipeline is extracted, further cleaning the gastroscope catheter and reducing the risk of contamination on the outer wall of the gastroscope catheter.

[0025] Through the design of the cleaning part, the disinfectant liquid pumped by the water pump cleans the driving wheel through multiple steps, avoiding cross-infection caused by residual mucus.

[0026] Through the linkage design of the support component and the opening and closing part, the present invention can quickly and accurately open and reset the patient's mouth as needed, reducing the oral discomfort caused by long-term high-intensity support. The rubber sleeve on the support block not only ensures hygiene but also reduces the friction on the oral mucosa, improving the comfort of the patient;

[0027] Through the linkage design of the scraping component and the linkage part, when the gastroscope catheter is pulled out, the two scraping rings can form an annular structure, which can effectively scrape off the mucus on the outer wall of the gastroscope catheter, avoiding the residue of mucus on the gastroscope catheter, thereby reducing the risk of cross-infection; when the pipeline is inserted, the two scraping plates move away from each other and do not contact the gastroscope catheter, thereby reducing the friction with the gastroscope catheter and avoiding the risk of infecting the gastroscope catheter.

The "in a preferred implementation mode" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0054] Thirdly, the present invention is described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0055] Please refer to the appendix Figures 1 to 14 As shown, this embodiment provides an auxiliary device for gastroscopy examination in the department of gastroenterology, including a housing 1, a support seat 2 fixedly connected to the upper end of the housing 1, and a protective shell 4 is also provided on the front surface of the housing 1;

[0056] A support assembly 3 is provided on a support base 2 and is used to expand a patient's oral cavity;

[0057] A rotating shaft 5 is rotatably connected inside a housing 1, and the front end of the rotating shaft 5 penetrates to the outside of a protective housing 4. A driving wheel 6 is fixedly installed on the outer wall of the rotating shaft 5. When the driving wheel 6 operates, it drives a gastroscope catheter to move, and through holes in a funnel shape are evenly distributed on the driving wheel 6;

[0058] A scraping component 7 is provided at the lower end of the housing 1 and is used to scrape off the mucus remaining on the gastroscope catheter;

[0059] An auxiliary mechanism 8 is provided on the housing 1;

[0060] Among them, the auxiliary mechanism 8 includes a cleaning part 81 which is provided inside the housing 1 and is located at the driving wheel 6 and is used to clean the mucus remaining on the driving wheel 6. A linkage part 82 is provided inside the housing 1, and an opening and closing part 83 is provided on one side of the housing 1 and is used to control the opening and closing of the support assembly 3. A negative pressure part 84 is provided on the other side of the housing 1.

[0061] Secondly, please refer to again Figure 2 and Figure 9 , large gears 9 are installed on both rotating shafts 5, and the two large gears 9 mesh with each other. A driving motor 10 is installed on the side of the housing 1, and the output shaft of the driving motor 10 is fixedly connected to one of the rotating shafts 5.

[0062] In this embodiment, the driving motor 10 is started to rotate forward, thereby driving one of the rotating shafts 5 to rotate. At the same time, the large gears 9 on the two rotating shafts 5 interact through meshing transmission to ensure that the two rotating shafts 5 can rotate in opposite directions synchronously. As the rotating shaft 5 rotates, the driving wheel 6 is also driven, and then the gastroscope catheter is driven to move upward. Conversely, if the driving motor 10 is controlled to rotate in reverse, then the gastroscope catheter will be withdrawn to achieve the descending action.

[0063] Please refer to again Figure 1 , Figure 3 , Figure 4 , Figure 9 and Figure 10, the cleaning unit 81 includes a first round rod 811 which is rotatably connected to the inner walls on both sides of the housing 1. A cleaning roller 812 and a first transmission gear 8110 are mounted on the first round rod 811. Flushing seats 813 are also fixedly connected to the inner walls on both sides of the housing 1, and spray heads are evenly distributed on the flushing seats 813. A water pump 814 is mounted on the side of the protective shell 4. The drainage end of the water pump 814 is connected to a drainage pipe 815, and the drainage pipe 815 communicates with the flushing seat 813. A hollow shell 816 is provided on the drainage pipe 815. A second round rod 817 is rotatably connected to the hollow shell 816. A water wheel 818 and a second transmission gear 819 are mounted on the second round rod 817, and the water wheel 818 is located in the hollow shell 816. A shunt pipe 8111 is connected to the drainage pipe 815. The shunt pipe 8111 extends from the cavity of the rotating shaft 5 into the driving wheel 6, and an annular spray cover 8112 is mounted at the end of the shunt pipe 8111.

[0064] In this embodiment, after the device is used up, the water intake end of the water pump 814 is connected to an external disinfectant storage tank, and the water pump 814 is started to pump the disinfectant therein. Subsequently, these disinfectants will flow along the drainage pipe 815 and finally enter the interior of the flushing seat 813. Inside the flushing seat 813, the disinfectants will be sprayed out to carry out flushing and cleaning work on the driving wheel 6 and the cleaning roller 812.

[0065] Meanwhile, during the process of water flowing through the hollow shell 816, it will push the water wheel 818 to rotate. The rotation of the water wheel 818 will further drive the rotation of the second round rod 817 and the second transmission gear 819. The second transmission gear 819 is tightly connected to the first transmission gear 8110 through a toothed belt, so that the first transmission gear 8110 also starts to rotate. The rotation of the first transmission gear 8110 will drive the rotation of the first round rod 811, and the rotation of the first round rod 811 will drive the rotation of the cleaning roller 812, thereby effectively brushing the driving wheel 6 and significantly improving the cleaning effect.

[0066] During this process, a part of the disinfectant will also flow into the annular spray cover 8112 through the shunt pipe 8111. These disinfectants will finally be sprayed out from the annular spray cover 8112 to carry out a comprehensive flushing on the inside of the driving wheel 6 to ensure that every corner can be thoroughly cleaned. Through this multi-step flushing and cleaning mechanism, the device can maintain an efficient and hygienic operating state.

[0067] Please refer to again Figure 5 、 Figure 6 and Figure 10, the linkage part 82 includes a slide rail 821. The slide rail 821 is fixedly connected to the inner wall of the housing 1 by a support rod. A rack 822 is slidably connected to the slide rail 821. A trapezoidal block 823 is fixedly connected to the side of the rack 822. Guide rods 824 are connected to both ends of the rack 822. A tooth 825 is slidably connected to the guide rod 824. A third compression spring 826 is sleeved on the guide rod 824. Third transmission gears 827 are installed at both ends of the rotating shaft 5.

[0068] Secondly, please refer to again Figure 5 , Figure 7 and Figure 8 , the scraping component 7 includes a mounting plate 701. The mounting plate 701 is connected to the lower end of the housing 1. A guiding seat 702 is connected to the top surface of the mounting plate 701. Guide grooves 703 are formed at the four corners of the mounting plate 701. Guide blocks 704 are slidably connected in the guide grooves 703. A second compression spring 705 is connected between the guide block 704 and the guide groove 703. Brackets 706 are connected to two guide blocks 704 on each side. A scraping ring 707 is connected to the bracket 706. The mounting plate 701 can be connected to the lower end of the housing 1 by bolts or other quick-release structures, as long as the purpose of convenient disassembly can be achieved. The specific connection method is not limited here.

[0069] In this embodiment, when the drive motor 10 operates in a forward rotation mode, the third transmission gear 827 on the rotating shaft 5 meshes with the rack 822. This meshing state causes the rack 822 to move upward along the slide rail 821. When the rack 822 reaches the upper limit position of its movement range, the third transmission gear 827 no longer meshes with the rack 822, but instead meshes with the tooth 825 below the rack 822. This new meshing state causes the tooth 825 to move upward along the guide rod 824 and apply pressure to the third compression spring 826. At this time, the third transmission gear 827 continuously meshes with the tooth 825 and continuously pushes the tooth 825 to move upward along the guide rod 824. During the period when the third transmission gear 827 is not meshed with the rack 822, due to the restoring force of the third compression spring 826, the tooth 825 will descend, so the rack 822 will not continue to move upward in this state. At the same time, in this state, the two scraping rings 707 are in a non-contact state with the gastroscope catheter to avoid contamination of the entering gastroscope catheter caused by contact between the scraping ring 707 and the gastroscope catheter.

[0070] It should be noted that: the shapes and sizes of the teeth on the tooth 825 and the rack 822 are the same.

[0071] When the driving motor 10 is reversed and the gastroscope catheter is extracted, the situation is the opposite. At this time, the third transmission gear 827 will drive the rack 822 to descend. The descent of the rack 822 will drive the trapezoidal block 823 to descend. The descending trapezoidal block 823 will apply pressure to the bracket 706, prompting the two brackets 706 to approach each other. When the brackets 706 approach each other, the semicircular scraping rings 707 on both sides will be driven to approach each other, and finally form a complete circular ring. In this state, the scraping ring 707 contacts the outer wall of the gastroscope catheter and can scrape off the mucus adhered to the outer wall of the gastroscope catheter. In the process of the brackets 706 approaching each other, the guide block 704 will be driven to move and squeeze the second compression spring 705. Therefore, when the trapezoidal block 823 no longer squeezes the bracket 706, under the reset force of the second compression spring 705, the guide block 704 will drive the bracket 706 and the scraping ring 707 away from each other, thereby returning to the initial state.

[0072] It should be noted that the scraper ring 707 is made of rubber material, which has good elasticity and wear resistance, and can effectively remove dirt on the surface of the gastroscope tube without damaging the gastroscope tube. In addition, the material of the scraper ring 707 also has a certain chemical corrosion resistance, and can adapt to various chemical substances that may be contacted during gastroscopy. In actual use, the replacement cycle of the scraper ring 707 is long, which reduces maintenance costs and operation time, and improves work efficiency.

[0073] The scraper assembly 7 is detachably connected to the lower end of the housing 1, which is convenient for the staff to remove it for cleaning and maintenance, ensuring that the scraper assembly 7 can continue to maintain the best cleaning effect during the gastroscopy. The whole process is fast and convenient, greatly improving the use efficiency and maintenance convenience of the equipment.

[0074] Please refer again Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The opening and closing portion 83 includes a cam 831, which is mounted on one end of the rotating shaft 5. A first hollow cylinder 832 is fixedly connected to the side of the shell 1, and a first piston rod 833 is inserted at one end of the first hollow cylinder 832. A fourth compression spring 834 is sleeved on the first piston rod 833, and a first piston plate 835 is fixedly connected to one end of the first piston rod 833. A second hollow cylinder 836 is fixedly connected to the support seat 2, and second piston rods 837 are inserted at both ends of the second hollow cylinder 836, and one end of the second piston rod 837 is fixedly connected to the lifting rod 304, and the other end of the second piston rod 837 is fixedly connected to the second piston plate 838, and a fifth compression spring 839 is fixedly connected between the two second piston plates 838. Air outlet holes 8310 are provided at both ends of the second hollow cylinder 836, and an air pipe 8311 is connected between the first hollow cylinder 832 and the second hollow cylinder 836.

[0075] It should be added that an air inlet is provided at one end of the first hollow cylinder 832 located on the gas transmission pipe 8311, and a one-way valve is arranged inside the air inlet. The function of this one-way valve is that when the first piston plate 835 moves along the first hollow cylinder 832 to draw air, the outside air can enter the first hollow cylinder 832 along the one-way valve.

[0076] Secondly, please also refer to Figure 2 and Figure 14 , the support assembly 3 includes a chute 301 which is annularly distributed and opened on the support base 2. A slider 302 is slidably connected in the chute 301. A first compression spring 303 is connected between the slider 302 and the chute 301. A lifting rod 304 is connected between every two corresponding sliders 302, and a support block 305 is connected to the lifting rod 304.

[0077] In this embodiment, the patient needs to gently bite on the support block 305 for subsequent operations. At this time, the gastroscope catheter will be inserted from the position of the scraping component 7 and will pass through the area between the two driving wheels 6. Then, the gastroscope catheter will pass through the upper end part of the housing 1 and finally pass through the support assembly 3 and be inserted into the patient's oral cavity.

[0078] It should be added that a disposable rubber sleeve (not shown in the figure) is provided on the support block 305 to ensure the hygienic protection of the patient's oral cavity during use. This rubber sleeve can effectively prevent cross-infection and is replaced after each use, ensuring the hygienic safety of the examination. In addition, the surface of the rubber sleeve is designed to be relatively smooth, which can reduce the friction on the patient's oral mucosa and further improve the patient's comfort experience. In actual operation, the doctor only needs to simply replace the rubber sleeve to quickly prepare for the next examination, greatly improving the work efficiency.

[0079] Regardless of whether the driving motor 10 rotates forward or backward, during the process of driving the gastroscope catheter to move, the rotating shaft 5 will drive the cam 831 to rotate. During the rotation of the cam 831, it will contact the first piston rod 833, thereby pushing the first piston rod 833 to move towards the inside of the first hollow cylinder 832 and compressing the fourth compression spring 834. As the first piston rod 833 moves, the first piston plate 835 will also move accordingly, thereby compressing the air inside the first hollow cylinder 832. The compressed air will enter the second hollow cylinder 836 along the gas transmission pipe 8311. When the cam 831 does not contact the first piston rod 833, the first piston rod 833 and the first piston plate 835 will be driven to reset under the restoring force of the fourth compression spring 834 for air extraction.

[0080] The air entering the second hollow cylinder 836 will push the two second piston plates 838 away from each other. As the second piston plates 838 move away from each other, the two second piston rods 837 will also move away from each other accordingly. This movement of separation will prompt the two lifting rods 304 to move away from each other. The movement of the lifting rods 304 away from each other will drive the support blocks 305 to move away from each other, thereby opening the patient's oral cavity. The purpose of doing this is to facilitate the movement of the gastroscope catheter and reduce the friction generated between the gastroscope catheter and the interior of the oral cavity when it enters and exits.

[0081] As air is gradually input into the second hollow cylinder 836, when the second piston plate 838 moves to the end of the second hollow cylinder 836, the excess air will be discharged through the air outlet 8310. This process helps to limit the degree of oral cavity opening to ensure the comfort of the patient. In addition, when the gastroscope catheter is not being transmitted, the rotating shaft 5 will not rotate, so no gas will be sent into the second hollow cylinder 836. In this case, the fifth compression spring 839 generates a restoring force to pull the two second piston plates 838 and the second piston rods 837 closer to each other, prompting the two support blocks 305 to move closer to each other. At this time, the amplitude of the oral cavity opening is smaller to improve the comfort of the patient.

[0082] During the lifting process of the lifting rod 304, the slider 302 fixedly connected thereto will move along the sliding groove 301. The movement of the slider 302 can play a role in guiding and limiting to ensure the stability of the movement. At the same time, when the two sliders 302 move away from each other, they will squeeze the first compression spring 303. And in the case of no air pressure, the first compression spring 303 will also generate a restoring force to push the slider 302 to reset, thereby ensuring the stability and reliability of the entire system.

[0083] Please refer to again Figure 1 、 Figure 9 and Figure 10 , the negative pressure part 84 includes an exhaust fan 841. The exhaust fan 841 is installed on the protective shell 4. A hollow tube 842 is rotatably connected in the cavity of the rotating shaft 5. The suction end of the exhaust fan 841 is connected with a suction pipeline 843, and the suction pipeline 843 is communicated with the hollow tube 842; wherein, the shunt pipe 8111 is fixedly connected in the hollow tube 842, and the hollow tube 842 is fixedly connected to the protective shell 4 by means of a support rod.

[0084] In this embodiment, when the driving wheel 6 rotates to convey the gastroscope catheter, the exhaust fan 841 is started. The exhaust fan 841 extracts the air inside the driving wheel 6 through the suction pipeline 843 and the hollow tube 842, thereby forming a negative pressure state inside the driving wheel 6. This negative pressure state causes the through holes opened on the driving wheel 6 to generate suction force, and this suction force can effectively adsorb the gastroscope catheter to prevent the gastroscope catheter from slipping on the driving wheel 6 during the transmission process. In this way, the stability of the gastroscope catheter during the transmission process can be ensured.

[0085] In addition, during the process of withdrawing the gastroscope catheter, the suction force generated by the through holes on the driving wheel 6 can not only adsorb the gastroscope catheter, but also suck in some mucus adhering to the gastroscope catheter. This sucking effect not only helps to clean the gastroscope catheter, but also further improves the smoothness and efficiency of the conveying process.

[0086] It should be particularly supplemented that a filter screen is provided at one end of the hollow tube 842 located inside the driving wheel 6. The function of this filter screen is to prevent mucus from entering the interior of the hollow tube 842 during the sucking process, thereby avoiding possible blockages or other potential problems. In this way, the smoothness and efficiency of the entire conveying and cleaning process are ensured.

[0087] The working principle of the present invention is as follows:

[0088] Automatic insertion and withdrawal of the gastroscope catheter

[0089] Drive system: By means of the drive motor 10 installed on the side of the housing 1, two driving wheels 6 are driven to rotate, realizing the upward movement (insertion) or downward movement (withdrawal) of the gastroscope catheter.

[0090] The cleaning unit 81 extracts disinfectant liquid through the water pump 814 to wash and clean the driving wheel 6 and the cleaning roller 812. At the same time, the rotation of the water wheel 818 drives the cleaning roller 812 to rotate through the transmission gear, further improving the cleaning effect.

[0091] Intelligent opening of the oral cavity

[0092] Opening and closing part 83: One end of the rotating shaft 5 is provided with a cam 831. When the rotating shaft 5 rotates, the cam 831 pushes the first piston rod 833 to move inside the first hollow cylinder 832, squeezing the fourth compression spring 834. The movement of the first piston plate 835 sends the air in the first hollow cylinder 832 into the second hollow cylinder 836 through the air delivery pipe 8311, pushing the two second piston plates 838 away from each other, thereby driving the two second piston rods 837 and the lifting rod 304 away from each other to open the patient's oral cavity.

[0093] Reset mechanism: When the gastroscope catheter is not being transmitted, the rotating shaft 5 will not rotate, so no gas will be sent into the second hollow cylinder 836. In this case, the fifth compression spring 839 generates a reset force to pull the two second piston plates 838 and the second piston rods 837 closer to each other, prompting the two support blocks 305 to move closer to each other. At this time, the opening amplitude of the oral cavity is smaller to improve the comfort of the patient.

[0094] Cleaning of the gastroscope catheter

[0095] Scraping component 7: When the drive motor 10 rotates in reverse and the gastroscope catheter is withdrawn, the third transmission gear 827 drives the rack 822 to descend, and the trapezoidal block 823 also descends accordingly, applying pressure to the bracket 706, prompting the two brackets 706 to approach each other and form a complete circular ring. The scraping ring 707 contacts the outer wall of the gastroscope catheter and scrapes off the mucus on the outer wall of the gastroscope catheter. During the process of the brackets 706 approaching each other, the guide block 704 moves and compresses the second compression spring 705. When the trapezoidal block 823 no longer presses the bracket 706, the restoring force of the second compression spring 705 causes the guide block 704 to drive the bracket 706 and the scraping ring 707 to move away from each other and return to the initial state.

[0096] Negative pressure part 84: Start the exhaust fan 841, and extract the air inside the drive wheel 6 through the exhaust duct 843 and the hollow tube 842 to form a negative pressure state. This negative pressure state generates suction force on the through holes of the drive wheel 6, adsorbs the gastroscope catheter and prevents slipping. At the same time, the suction force can also suck in some mucus to further clean the gastroscope catheter.

[0097] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
