[0038] Example 1

[0039] Reference Figures 1-4 , which is the first embodiment of the present invention, provides a painless gastroenteroscopic oropharyngeal airway with multi-level positioning function.

[0040] Specifically, it includes: an occlusal mechanism 100, which includes an occlusal component for assisting a patient in performing gastroscopy to occlude and a first positioning component for assisting a patient in performing external fixation positioning;

[0041] An endoscope mechanism 200, comprising an oral positioning portion 204 for auxiliary fixation in a patient's oral cavity and an endoscope component 203 for auxiliary fixation in a patient's trachea;

[0042] The first positioning component is detachably mounted on the bite component, and further comprises a third positioning component, wherein the third positioning component is fixedly connected to the oral positioning portion 204, and the oral positioning portion 204 is detachably mounted on the bite component.

[0043] The bite assembly includes a bite piece 101, and a mounting piece 102 is fixedly installed on one side of the bite piece 101. A mounting piece 2 103 for fixing the oral positioning part 204 is provided on the mounting piece 102. A breathing cylinder 104 is installed on the top of the mounting piece 103. A cavity is opened in the breathing cylinder 104. An intake pipe 106 is connected to one side of the breathing cylinder 104. An air inlet pipe 105 for assisting the patient's nasal breathing is symmetrically connected to the top of the breathing cylinder 104. A tongue depressor 107 for pressing the patient's tongue is provided on the other side of the bite piece 101. Connection holes for detachably connecting the first positioning assembly are symmetrically opened on both sides of the mounting piece 102.

[0044] Among them, the occlusal assembly includes an occlusal member 101, a mounting member 102 on one side of which is used to connect and carry other components, a mounting member 2 103 on the mounting member 102 is used to provide an interface for connecting the oral positioning part 204, and at the same time, the breathing cylinder 104 on the top of the mounting member 2 103 is used to achieve nasal breathing assistance; the cavity inside the breathing cylinder 104 can be used for gas flow, and the suction tube 106 and the air inlet tube 105 are both connected to the cavity to form a breathing passage; the suction tube 106 can be used to connect with other suction equipment, and the air inlet tube 105 assists the patient to breathe through the nasal cavity, which is used to allow the patient to maintain a normal posture during gastrointestinal endoscopy. Normal breathing, avoiding breathing difficulties due to occupied oral cavity, improving the comfort and safety of patients; the tongue depressor 107 on the other side of the bite piece 101 is used to press the patient's tongue, which helps to prevent the tongue from obstructing the operation path of the gastroenteroscope, and at the same time can position and protect the tongue to a certain extent to prevent accidental injury to the tongue; the connecting holes on both sides of the mounting piece 102 provide a position for the installation of the first positioning component, and the pad 108 in the first positioning component is detachably connected to the bite mechanism 100 through the connecting hole, which is used to adjust and replace according to different usage scenarios or different patient head sizes, thereby improving the flexibility of the device.

[0045] The first positioning component includes a pad 108 that is detachably connected through a connecting hole. A plug-in component 109 is fixed to the other end of the pad 108. The plug-in components 109 correspond one-to-one to the pad 108. The two plug-in components 109 are mirror-imaged and locked with each other to form a lock.

[0046] The plug assembly 109 includes an elastic band 1091 fixedly connected to the backing plate 108, one end of the elastic band 1091 is fixedly connected to the plug block 1092, and a second mounting plate 1097 and a first mounting plate 1096 are fixedly provided along one side of the height of the plug block 1092. A positioning member 1098 is slidably provided in the plug block 1092, and the positioning member 1098 is located between the second mounting plate 1097 and the first mounting plate 1096 and is slidably connected to the first mounting plate 1096;

[0047] The top and bottom of the plug block 1092 are respectively provided with a limiting groove 1 and a limiting groove 2, one end of the positioning member 1098 passes through the limiting groove 2 and is limited by the plug block 1092, a retractable telescopic rod 1095 is fixed to the positioning member 1098, the other end of the telescopic rod 1095 is fixed with a latch 1094, the other end of the latch 1094 passes through the limiting groove 1, and a fixing seat 1093 is also fixed to the plug block 1092, and one end of the latch 1094 passes through the plug block 1092 and is fixedly connected to the fixing seat 1093;

[0048] Among them, one end of the elastic band 1091 is connected to the pad 108, and the other end is connected to the plug-in block 1092. The elastic band 1091 can provide a certain elastic deformation ability, so that it can adapt to the head shapes and sizes of different patients and play a role of buffering and fitting.

[0049] The mounting plate 2 1097 in the plug-in block 1092 is straight, the mounting plate 1 1096 is curved, and one end of the positioning member 1098 is an arc-shaped structure and fits the curve of the mounting plate 1 1096. Therefore, the positioning member 1098 slides on the mounting plate 1 1096 in the plug-in block 1092, and is located between the mounting plate 2 1097 and the mounting plate 1 1096 and is slidably connected to the mounting plate 1 1096, limiting the sliding trajectory and range of the positioning member 1098.

[0050] Limiting slot 1 and limiting slot 2 respectively limit one end of the positioning member 1098 and one end of the telescopic rod 1095 to prevent them from sliding excessively. The telescopic rod 1095 on the positioning member 1098 is combined with the latch 1094. The latch 1094 extends through limiting slot 1 and is fixedly connected to the fixing seat 1093. The position and state of the positioning member 1098 can be changed by extending and retracting the telescopic rod 1095 and fixing the position of the latch 1094. When the two positioning members 1098 are mirror-imaged and close to each other, the two positioning members 1098 are tightly attached to each other and rotate counterclockwise with each other through the extension of the telescopic rod 1095, thereby realizing a locking function. After the position of the first positioning component is adjusted, it is firmly locked to ensure the stability of the external fixation.

[0051] In summary, before use, the first positioning assembly is first installed on the mounting member 102 of the bite mechanism 100 through the connecting hole of the pad 108. The position of the first positioning assembly can be preliminarily adjusted according to the size and shape of the patient's head. During the adjustment process, the elastic band 1091 can undergo elastic deformation, and the positioning member 1098 can slide in the plug block 1092 to find a suitable installation position; at the same time, the installed tongue depressor 107 can press the patient's tongue to keep the tongue in the appropriate position to prevent it from affecting subsequent operations; after adjusting the position of the first positioning assembly, by operating the telescopic rod 1095 on the positioning member 1098, the position of the pin 1094 is changed, so that the two positioning members 1098 are mirror-imaged and mutually engaged to form a lock, thereby firmly fixing the first positioning assembly to the outside of the patient's head; the patient bites the bite member 101 to further fix the device. At the same time, the air inlet tube 105 of the respirator 104 assists the patient in nasal breathing, and the inhalation tube 106 can be connected to the inhalation equipment as needed to ensure that the patient can breathe smoothly during the entire examination process; and the oral positioning part 204 can be subsequently installed on the mounting part 2 103 to prepare for the subsequent operation of the endoscope mechanism 200 in the oral cavity.

[0052] Example 2

[0053] Reference Figures 5 to 9 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0054] Specifically, the endoscope mechanism 200 also includes an oral positioning component, which includes an oral positioning part 204 for assisting in opening the patient's mouth, and also includes a driving component 201 for driving the oral positioning part 204 to open or close. The oral positioning part 204 is fixedly mounted on the driving component 201, and the driving component 201 is detachably connected to the mounting part 103.

[0055] The driving component 201 includes a plug connector 2011, one end of which is provided with an air supply pipe 2012, and the other end of the plug connector 2011 is provided with a connecting plate 2013, the inner wall of the other end of the connecting plate 2013 is provided with an internal thread, the internal thread of the connecting plate 2013 is provided with an internal threaded barrel 2018, the top of the internal threaded barrel 2018 is provided with a threaded seat 2016, the outer wall of the threaded seat 2016 is sleeved with a sleeve 2014, the inner wall of the sleeve 2014 is slidably connected to the outer wall of the connecting plate 2013, the inner wall thread of the internal threaded barrel 2018 is provided with a connecting barrel 2017, the top of the connecting barrel 2017 is fixedly provided with a sleeve 2015, and the inner wall of the sleeve 2 2015 is slidably sleeved on the outer wall of the sleeve 1 2014.

[0056] The air supply pipe 2012 at one end of the plug connector 2011 is used to replenish air or connect to other auxiliary equipment. The connecting plate 1 2013 at the other end is threadedly connected to the internally threaded barrel 2018 to enable subsequent movement and force transmission. The internally threaded barrel 2018 and the connecting barrel 2017 are threadedly engaged, and a second sleeve 2015 is fixed to the top of the connecting barrel 2017. The inner wall of the first sleeve 2014, outside the threaded seat 2016 at the top of the internally threaded barrel 2018, is slidably connected to the outer wall of the connecting plate 1 2013. The inner wall of the second sleeve 2015 is slidably mounted on the outer wall of the first sleeve 2014. When the internally threaded barrel 2018 rotates, it drives the second sleeve 2015 to move relative to the first sleeve 2014.

[0057] The oral positioning portion 204 includes an inner support member 2041 fixedly mounted on the outer wall of the second sleeve 2015, an expansion member 2042 fixedly mounted on the outer wall of the first sleeve 2014, and a connecting collar 2043 mounted on the outer wall of one end of the connecting plate 2013. A second worm gear 2044 is fixedly mounted on one end of the connecting collar 2043. The inner support member 2041, the expansion member 2042, the connecting collar 2043, and the second worm gear 2044 are all coaxially distributed. A fixing plate 2046 is fixedly mounted on the outer wall of the plug connector 2011. A second worm gear 2045 is rotatably mounted on the fixing plate 2046. The second worm gear 2045 engages with the second worm gear 2044.

[0058] The second worm 2045 rotatably mounted on the fixed plate 2046 meshes with the second worm wheel 2044. Rotating the second worm 2045 drives the connecting collar 2043 through the transmission of the worm wheel. Due to the connection between the connecting collar 2043, the inner support member 2041, and the expansion member 2042, the inner support member 2041 and the expansion member 2042 expand or contract, thereby opening or closing the oral cavity.

[0059] Specifically, when it is necessary to open the patient's mouth, the worm gear 2045 is manually driven, and the worm gear 2045 drives the worm gear 2044 to rotate. Since the connecting collar 2043 is fixedly connected to the worm gear 2044, the connecting collar 2043 will rotate. At the same time, the threaded connection between the internal threaded barrel 2018 and the connecting plate 1 2013, as well as the sliding and relative movement between the sleeve 1 2014 and the endoscope 2031, will cause the internal support member 2041 and the expansion member 2042 to expand outward, thereby opening the patient's mouth. Conversely, rotating the worm gear 2045 in the opposite direction can close the oral positioning part 204, so that the device can flexibly adjust the degree of opening according to the size and shape of the patient's mouth, thereby improving the adaptability of the device, ensuring that sufficient operating space is provided for subsequent endoscopic operations, avoiding damage to oral tissue, and improving the patient's comfort.

[0060] Furthermore, in the initial state, the internal support member 2041, the expansion member 2042, and the connecting ring 2043 in the oral positioning portion 204 are in an unexpanded state, that is, the internal support member 2041 and the expansion member 2042 are relatively contracted, and no expansion operation is performed on the oral cavity. The internal threaded barrel 2018 in the drive component 1 201 is connected to the internal thread of the connecting plate 1 2013 through a threaded connection, the sleeve 1 2014 is sleeved on the outer wall of the threaded seat 2016, and the inner wall of the sleeve 1 2014 is slidably connected to the outer wall of the connecting plate 1 2013, the inner wall of the sleeve 2015 is slidably sleeved on the outer wall of the sleeve 1 2014, and the connecting barrel 2017 is fixed to the top of the endoscope 2031 and is threadedly connected to the internal threaded barrel 2018. At the same time, the worm 2 2045 on the fixed plate 2046 is in meshing state with the worm gear 2 2044, but no rotational force has been applied;

[0061] When the patient's mouth needs to be opened, the medical staff manually rotates the worm 2045. Since the worm 2045 is meshed with the worm gear 2044, according to the worm gear transmission principle, the rotation of the worm 2045 drives the worm gear 2044 to rotate, and the rotation of the worm gear 2044 causes the connecting ring 2043 fixed to it to start rotating;

[0062] The rotation of the connecting ring 2043 will drive the inner support member 2041 and the expansion member 2042 to produce corresponding movement; the inner support member 2041 is fixedly sleeved on the outer wall of the endoscope 2031, and the expansion member 2042 is fixedly sleeved on the outer wall of the sleeve 1 2014, and the relative position between the sleeve 1 2014 and the endoscope 2031 is constrained by the threaded connection between the internal threaded tube 2018 and the connecting tube 2017 and the sliding sleeve relationship between them. When the worm gear 2044 drives the connecting ring 2043 to rotate, since the inner wall of the sleeve 1 2014 is slidingly connected to the outer wall of the connecting plate 1 2013, the internal threaded tube 2018 is threadedly connected to the connecting plate 1 2013, and the rotation of the internal threaded tube 2018 will drive the connecting tube 2017 to move relative to each other.

[0063] When the internal threaded cylinder 2018 rotates clockwise, it will push the connecting cylinder 2017 to move upward (upward is the direction away from the connecting plate 2013), and the connecting cylinder 2017 will drive the endoscope 2031 to move upward. Since the inner wall of the endoscope 2031 is slidably mounted on the outer wall of the sleeve 2014, this relative movement causes the inner support member 2041 and the expansion member 2042 to begin to expand outward. As the worm 2045 continues to rotate, the degree of expansion of the inner support member 2041 and the expansion member 2042 will gradually increase, thereby realizing the operation of opening the patient's mouth.

[0064] When the gastrointestinal endoscopy operation is completed or the oral positioning part 204 needs to be retracted, the medical staff will perform the opposite operation and rotate the worm gear 2045 in the opposite direction. At this time, according to the reverse transmission of the worm gear, the worm gear 2044 will rotate in the opposite direction, and the internal threaded cylinder 2018 will rotate in the opposite direction in the connecting plate 1 2013, so that the connecting cylinder 2017 drives the endoscope 2031 to move downward (downward is the direction close to the connecting plate 1 2013), thereby causing the internal support member 2041 and the expansion member 2042 to shrink inward, thereby achieving the closure of the oral positioning part 204.

[0065] The third positioning assembly includes a second driving assembly 202 and an endoscope assembly 203. The second driving assembly 202 is fixedly mounted on the fixing plate 2046. The endoscope assembly 203 is fixedly connected to the other end of the first driving assembly 201.

[0066] The endoscope component 203 is used to penetrate into the patient's throat and fix it, and the second driving component 202 is used to adjust the fixing state of the endoscope component 203 according to the fixing state of the oral positioning part 204.

[0067] like Figure 8-Figure 9 As shown, the second driving assembly 202 includes an air intake cylinder 2021 fixedly mounted on the fixing plate 2046, one side of the air intake cylinder 2021 is connected to a mounting cylinder 2024, and one end of the mounting cylinder 2024 is connected to an air intake hole 2025;

[0068] A slide plate 20210 is slidably provided on the inner wall of the air intake cylinder 2021. A threaded rod 2026 is fixed to one end of the slide plate 20210. The other end of the threaded rod 2026 passes through the air intake cylinder 2021 and is rotatably connected to the air intake cylinder 2021. An abutment plate 2023 is sleeved on the threaded rod 2026. A spring 2029 is provided between the abutment plate 2023 and the inner wall of the air intake cylinder 2021. The spring 2029 is sleeved on the outer wall of the threaded rod 2026.

[0069] The outer wall of the threaded rod 2026 is also provided with an external thread, and the outer wall of the threaded rod 2026 is threaded with a worm gear 2028. A worm 2027 is provided on the outer wall of the air intake cylinder 2021 through a connecting shaft, and the worm 2027 is threadedly connected to the worm gear 2028. An air outlet 2022 is opened on the outer wall of the air intake cylinder 2021, and the air intake cylinder 2021 is provided with a connecting pipe 2034 that is connected to the interior of the air intake cylinder 2021 through the air outlet 2022.

[0070] The endoscope assembly 203 includes an endoscope tube 2031 having one end fixedly connected to one end of the driving assembly 1 201, an oblique insertion tube 2032 fixedly provided on the other end of the endoscope tube 2031, an air bag 2033 sheathed on the outer wall of the endoscope tube 2031, and the other end of the connecting tube 2034 connected to the air bag 2033;

[0071] In the initial state, the endoscope tube 2031 and the oblique cannula 2032 of the endoscope assembly 203 are not inserted into the patient's throat, and the airbag 2033 is not inflated. The slide plate 20210 in the second drive assembly 202 is located at the initial position of the air inlet cylinder 2021, the spring 2029 on the threaded rod 2026 is at its natural length or pre-tensioned state, the abutment plate 2023 is in a corresponding position under the action of the spring 2029, and the worm gear 1 2028 and the worm 1 2027 are not rotating.

[0072] When preparing to begin a gastrointestinal endoscopy, the endoscope 2031 is first fixedly connected to one end of the drive assembly 201 and inserted along the patient's oral cavity and throat. The design of the oblique insertion tube 2032 helps guide the endoscope 2031 into the throat better because its special oblique structure can adapt to the physiological curvature of the throat, reducing the resistance during insertion and making the insertion process smoother.

[0073] While inserting the endoscope tube 2031, the first worm gear 2027 is rotated to allow air to flow into the air intake cylinder 2021 through the air intake hole 2025 of the mounting cylinder 2024. At this time, the oral cavity positioning unit 204 slowly opens the oral cavity under the rotation of the first worm gear 2027, providing the necessary space for the insertion of the endoscope tube 2031 and preventing the oral cavity tissue from obstructing the insertion of the endoscope tube 2031. Furthermore, the expanded state of the oral cavity positioning unit 204 affects the subsequent operation of the third positioning assembly, as the second driving assembly 202 needs to adjust the fixed state of the endoscope assembly 203 based on the fixed state of the oral cavity positioning unit 204.

[0074] When the endoscope tube 2031 is inserted to a certain position, in order to fix the endoscope assembly 203 in the throat, it is necessary to start the driving assembly 202. The medical staff manually rotates the worm 1 2027.

[0075] Because worm 1 2027 and worm wheel 1 2028 are threadedly connected, according to the principle of worm gear transmission, the rotation of worm 1 2027 drives the rotation of worm wheel 1 2028, which in turn causes axial movement of threaded rod 2026, which is threadedly connected thereto. Because slide plate 20210 is fixed to one end of threaded rod 2026 and threaded rod 2026 passes through and is rotationally connected to air intake cylinder 2021, when threaded rod 2026 rotates, it moves along its axial direction. When worm wheel 1 2028 rotates clockwise, threaded rod 2026 moves axially within air intake cylinder 2021, pushing slide plate 20210 to slide against the inner wall of air intake cylinder 2021. As threaded rod 2026 moves axially, the abutment plate 2023 mounted on threaded rod 2026 also moves accordingly. At this time, the spring 2029 is compressed, and the mounting tube 2024 can introduce gas through the air inlet 2025. When the slide plate 20210 slides past the air outlet 2022 and approaches the side of the abutment plate 2023, the gas can be transmitted to the air bag 2033 through the air outlet 2022.

[0076] During the adjustment process of the second driving component 202, the airbag 2033 is inflated through the connecting tube 2034. The inflated airbag 2033 expands in the throat, making it fit tightly against the inner wall of the throat, thereby fixing the endoscope 2031 and preventing the endoscope 2031 from moving during the inspection process, thereby ensuring the stability and accuracy of the endoscopic operation.

[0077] When the gastrointestinal endoscopy is completed, the gas in the airbag 2033 is first discharged through the connecting tube 2034 to shrink the airbag 2033 and release the fixation of the endoscope 2031. Then the endoscope 2031 is slowly taken out from the throat, and the worm 2027 is rotated in the opposite direction to drive the worm gear 2028 and the threaded rod 2026 to move in the opposite direction, so that the slide plate 20210 is reset on the inner wall of the air inlet cylinder 2021, and the abutment plate 2023 returns to its initial position under the elastic restoring force of the spring 2029, so that the entire drive assembly 202 is restored to its initial state.

[0078] In summary, through the cooperation of the driving component 202 and the endoscope component 203, and by utilizing the worm gear transmission and the elastic effect of the spring 2029, the fixed state of the endoscope 2031 in the throat can be accurately adjusted, so that the device can be adaptively adjusted according to the physiological structure of the throat and the state of the oral positioning part 204 of different patients, thereby improving the adaptability and fixed stability of the device, ensuring the stability of the position of the endoscope 2031 during the examination process, and helping to improve the accuracy and safety of the examination.

[0079] The inflation fixation method of the airbag 2033 avoids the damage to the laryngeal tissue that may be caused by traditional rigid fixation. Through soft contact and sealing with the inner wall of the laryngeal tube, it reduces the pressure and damage to the patient's throat and improves the patient's comfort and safety.

[0080] The cooperation between the driving component 202, the endoscope component 203 and the oral positioning part 204 ensures the coordinated work of the entire device during the gastrointestinal endoscopy, realizes seamless connection and coordinated operation from the mouth to the throat, and provides complete and stable positioning and operating conditions for the examination.
