[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings of the specification.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selectively exclusive embodiment from other embodiments.

[0031] Embodiment 1 Refer to Figures 1-4 , which is the first embodiment of the present invention. This embodiment provides an oropharyngeal airway dedicated for painless gastroscopy and colonoscopy with a multi-stage positioning function.

[0032] Specifically, it includes: a biting mechanism 100, which includes a biting component for assisting the patient to bite during gastroscopy and a first positioning component for assisting the patient in external fixed positioning; An endoscopy mechanism 200, which includes an oral positioning part 204 for assisting in fixation within the patient's oral cavity and an endoscopy component 203 for assisting in fixation within the patient's trachea; The first positioning component is detachably mounted on the biting component, and further includes a third positioning component. The third positioning component is fixedly connected to the oral positioning part 204, and the oral positioning part 204 is detachably mounted on the biting component.

[0033] The biting component includes a biting piece 101. On one side of the biting piece 101, a first mounting piece 102 is fixedly installed. On the first mounting piece 102, a second mounting piece 103 for fixing the oral positioning part 204 is provided. On the top of the second mounting piece 103, a breathing tube 104 is installed. A cavity is provided inside the breathing tube 104. On one side of the breathing tube 104, an air suction tube 106 is communicated. On the top of the breathing tube 104, air inlet tubes 105 for assisting the patient's nasal breathing are symmetrically communicated. On the other side of the biting piece 101, a tongue depressor 107 for pressing the patient's tongue is provided. On both sides of the first mounting piece 102, connection holes for detachably connecting the first positioning component are symmetrically provided.

[0034] Among them, the biting component includes a biting piece 101. The first mounting piece 102 on one side is used to connect and carry other components. The second mounting piece 103 on the first mounting piece 102 provides an interface for connecting the oral positioning part 204. At the same time, the breathing tube 104 on the top of the second mounting piece 103 is used to realize nasal breathing assistance; the cavity inside the breathing tube 104 can be used for gas flow. The air suction tube 106 and the air inlet tubes 105 are both communicated with the cavity, constituting a breathing passage; the air suction tube 106 can be used to connect with other air suction devices. The air inlet tubes 105 assist the patient to breathe through the nose, enabling the patient to maintain normal breathing during gastroscopy and colonoscopy examinations, avoiding dyspnea caused by the occupation of the oral cavity, and improving the comfort and safety of the patient; the tongue depressor 107 on the other side of the biting piece 101 is used to press the patient's tongue, which helps to prevent the tongue from blocking the operation path of the gastroscope and colonoscope. At the same time, it can position and protect the tongue to a certain extent to prevent accidental injury to the tongue; the connection holes on both sides of the first mounting piece 102 provide positions for the installation of the first positioning component. The backing plate 108 in the first positioning component is detachably connected to the biting mechanism 100 through the connection holes, which is used for adjustment and replacement according to different usage scenarios or the head sizes of different patients, improving the flexibility of the device.

[0035] The first positioning component includes a backing plate 108 detachably connected through a connection hole. At the other end of the backing plate 108, a plugging component 109 is fixedly provided. The plugging components 109 correspond to the backing plate 108 one by one. The two plugging components 109 are mirror-symmetrically distributed and are clamped with each other to form a lock.

[0036] The plugging component 109 includes an elastic band 1091 fixedly connected to the backing plate 108. At one end of the elastic band 1091, a plugging block 1092 is fixedly connected. Inside the plugging block 1092, a second mounting plate 1097 and a first mounting plate 1096 are fixedly provided along one side in the height direction. A positioning member 1098 is slidably provided inside the plugging block 1092. 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. A first limiting groove and a second limiting groove are respectively formed at the top and bottom of the plugging block 1092. One end of the positioning member 1098 passes through the second limiting groove and is limited by the plugging block 1092. A telescopic rod 1095 is fixedly provided on the positioning member 1098. At the other end of the telescopic rod 1095, a plug pin 1094 is fixedly provided. The other end of the plug pin 1094 passes through the first limiting groove. A fixed seat 1093 is also fixedly provided on the plugging block 1092. The end of the plug pin 1094 passing through the plugging block 1092 is fixedly connected to the fixed seat 1093. Among them, one end of the elastic band 1091 is connected to the backing plate 108, and the other end is connected to the plugging block 1092. The elastic band 1091 can provide a certain elastic deformation ability, enabling it to adapt to the head shapes and sizes of different patients, and playing a role in buffering and fitting.

[0037] The second mounting plate 1097 inside the plugging block 1092 is linear, and the first mounting plate 1096 is curved. One end of the positioning member 1098 is an arc-shaped structure and fits the curve of the first mounting plate 1096. Therefore, the positioning member 1098 slides on the first mounting plate 1096 inside the plugging block 1092, is located between the second mounting plate 1097 and the first mounting plate 1096, and is slidably connected to the first mounting plate 1096, restricting the sliding track and range of the positioning member 1098.

[0038] Limiting groove 1 and limiting groove 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 and the latch 1094 on the positioning member 1098 are combined, and the latch 1094 passes through the limiting groove 1 and is fixedly connected to the fixing seat 1093. The position and state of the positioning member 1098 can be changed by the extension and contraction of the telescopic rod 1095 and the position fixation of the latch 1094. When the two positioning members 1098 are mirror-imaged and close to each other, the two positioning members 1098 are closely attached and rotated counterclockwise relative to each other through the extension of the telescopic rod 1095, thereby realizing the locking function, which is used to firmly lock the first positioning component after adjusting its position to ensure the stability of the external fixation; 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. According to the size and shape of the patient's head, the position of the first positioning assembly can be preliminarily adjusted. During the adjustment process, the elastic band 1091 can be elastically deformed, 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 a suitable 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 latch 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 pipe 105 of the respirator 104 assists the patient in nasal breathing, and the air inlet pipe 106 can be connected to the air inhalation device 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 103 to prepare for the subsequent operation of the endoscope mechanism 200 in the oral cavity.

[0039] Example 2 Reference Figures 5-9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0040] 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.

[0041] The first driving component 201 includes a plug connector 2011. One end of the plug connector 2011 is provided with a gas supplement pipe 2012, and the other end of the plug connector 2011 is provided with a first connecting plate 2013. The inner wall of the other end of the first connecting plate 2013 is provided with internal threads, and an internal thread cylinder 2018 is arranged on the internal threads of the first connecting plate 2013. The top end of the internal thread cylinder 2018 is provided with a threaded seat 2016. A first sleeve 2014 is sleeved on the outer wall of the threaded seat 2016. The inner wall of the first sleeve 2014 is slidably connected to the outer wall of the first connecting plate 2013. A connecting cylinder 2017 is arranged on the internal threads of the inner wall of the internal thread cylinder 2018. The top end of the connecting cylinder 2017 is fixedly provided with a second sleeve 2015. The inner wall of the second sleeve 2015 is slidably sleeved on the outer wall of the first sleeve 2014.

[0042] Among them, the gas supplement pipe 2012 at one end of the plug connector 2011 is used to supplement gas or connect other auxiliary devices, and the first connecting plate 2013 at the other end is threadedly connected to the internal thread cylinder 2018 to achieve subsequent movement and force transmission; the internal thread cylinder 2018 and the connecting cylinder 2017 are in threaded cooperation, and a second sleeve 2015 is fixedly arranged at the top end of the connecting cylinder 2017. The inner wall of the first sleeve 2014 outside the threaded seat 2016 at the top end of the internal thread cylinder 2018 is slidably connected to the outer wall of the first connecting plate 2013, and the inner wall of the second sleeve 2015 is slidably sleeved on the outer wall of the first sleeve 2014. When the internal thread cylinder 2018 rotates, it will drive the second sleeve 2015 to generate relative movement relative to the first sleeve 2014.

[0043] The oral cavity positioning part 204 includes an inner support member 2041 fixedly sleeved on the outer wall of the second sleeve 2015, an expansion member 2042 fixedly sleeved on the outer wall of the first sleeve 2014, and a connecting collar 2043 sleeved on the outer wall of one end of the first connecting plate 2013. One end of the connecting collar 2043 is fixedly provided with a second worm gear 2044. 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 arranged on the outer wall of the plug connector 2011. A second worm 2045 is rotatably arranged on the fixing plate 2046. The second worm 2045 meshes with the second worm gear 2044; Among them, the second worm 2045 rotatably arranged on the fixing plate 2046 meshes with the second worm gear 2044. When the second worm 2045 rotates, through the transmission of the worm and worm gear, it will drive the connecting collar 2043 to rotate. Due to the connection relationship among the connecting collar 2043, the inner support member 2041, and the expansion member 2042, the inner support member 2041 and the expansion member 2042 will generate expansion or contraction movement, realizing the opening or closing action of the oral cavity; Specifically, when it is necessary to expand the patient's oral cavity, the worm gear two 2045 is manually driven, and the worm gear two 2045 drives the worm wheel two 2044 to rotate. Since the connecting collar 2043 is fixedly connected to the worm wheel two 2044, the connecting collar 2043 will rotate. At the same time, due to the threaded connection between the internal threaded cylinder 2018 and the first connecting plate 2013, and the sliding and relative movement between the first sleeve 2014 and the endoscope tube 2031, the inner support member 2041 and the expansion member 2042 will expand outwards, thereby expanding the patient's oral cavity. Conversely, rotating the worm gear two 2045 in the reverse direction can close the oral cavity positioning part 204, enabling the device to flexibly adjust the degree of expansion according to the size and shape of the patient's oral cavity, improving the adaptability of the device, ensuring sufficient operating space for subsequent endoscopic operations, avoiding damage to oral tissues, and at the same time improving the patient's comfort; Further, in the initial state, the inner support member 2041, the expansion member 2042, and the connecting collar 2043 in the oral cavity positioning part 204 are in an unexpanded state, that is, the inner support member 2041 and the expansion member 2042 are relatively contracted and do not perform an expansion operation on the oral cavity. The internal threaded cylinder 2018 in the first driving assembly 201 is threadedly connected to the internal thread of the first connecting plate 2013. The first sleeve 2014 is sleeved on the outer wall of the threaded seat 2016, and the inner wall of the first sleeve 2014 is slidably connected to the outer wall of the first connecting plate 2013. The inner wall of the second sleeve 2015 is slidably sleeved on the outer wall of the first sleeve 2014, and the connecting cylinder 2017 is fixed to the top of the endoscope tube 2031 and is threadedly connected to the internal threaded cylinder 2018. At the same time, the worm gear two 2045 on the fixing plate 2046 is in a meshed state with the worm wheel two 2044, but no rotational force has been applied yet; When it is necessary to perform an expansion operation on the patient's oral cavity, the medical staff manually rotates the worm gear two 2045. Since the worm gear two 2045 is meshed with the worm wheel two 2044, according to the worm and worm wheel transmission principle, the rotation of the worm gear two 2045 will drive the worm wheel two 2044 to rotate, and the rotation of the worm wheel two 2044 will cause the connecting collar 2043 fixedly connected to it to start rotating; The rotation of the connecting collar 2043 will drive the inner support member 2041 and the expansion member 2042 to produce corresponding movements; the inner support member 2041 is fixedly sleeved on the outer wall of the endoscope tube 2031, and the expansion member 2042 is fixedly sleeved on the outer wall of the first sleeve 2014. The relative position between the first sleeve 2014 and the endoscope tube 2031 is restricted by the threaded connection between the internal threaded cylinder 2018 and the connecting cylinder 2017 and their sliding sleeve relationship. When the worm wheel two 2044 drives the connecting collar 2043 to rotate, due to the sliding connection between the inner wall of the first sleeve 2014 and the outer wall of the first connecting plate 2013, and the threaded connection between the internal threaded cylinder 2018 and the first connecting plate 2013, the rotation of the internal threaded cylinder 2018 will drive the connecting cylinder 2017 to move relatively.

[0044] When the internal threaded tube 2018 rotates clockwise, it will push the connecting tube 2017 to move upward (upward is the direction away from the connecting plate 2013), and the connecting tube 2017 will drive the endoscope tube 2031 to move upward. Since the inner wall of the endoscope tube 2031 is slidably sleeved 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 gear 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.

[0045] 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 tube 2018 will rotate in the connecting plate 1 2013 in the opposite direction, so that the connecting tube 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.

[0046] The third positioning assembly includes a second driving assembly 202 and an endoscope assembly 203, wherein the second driving assembly 202 is fixedly mounted on the fixing plate 2046, and the endoscope assembly 203 is fixedly connected to the other end of the first driving assembly 201; 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.

[0047] like Figures 8-9 As shown, the second driving assembly 202 includes an air inlet cylinder 2021 fixedly mounted on the fixing plate 2046, one side of the air inlet cylinder 2021 is connected to a mounting cylinder 2024, and one end of the mounting cylinder 2024 is connected to an air inlet hole 2025; A slide plate 20210 is slidably provided on the inner wall of the air inlet cylinder 2021, a threaded rod 2026 is fixedly provided at one end of the slide plate 20210, the other end of the threaded rod 2026 penetrates the air inlet cylinder 2021 and is rotatably connected to the air inlet 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 inlet cylinder 2021, and the spring 2029 is sleeved on the outer wall of the threaded rod 2026; The threaded rod 2026 is also provided with an external thread on its outer wall, and a worm gear 2028 is threadedly provided on its outer wall. A worm 2027 is rotatably provided on the outer wall of the air intake cylinder 2021 via a connecting shaft, and the worm 2027 is threadedly connected to the worm gear 2028. An air outlet 2022 is provided on the outer wall of the air intake cylinder 2021, and a connecting pipe 2034 is provided on the air intake cylinder 2021 to connect to the interior of the air intake cylinder 2021 via the air outlet 2022.

[0048] The endoscope assembly 203 includes an endoscope tube 2031 whose one end is fixedly connected to one end of the driving assembly 201, an oblique insertion tube 2032 is fixedly arranged on the other end of the endoscope tube 2031, an air bag 2033 is sleeved on the outer wall of the endoscope tube 2031, and the other end of the connecting tube 2034 is connected to the air bag 2033; 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 drive assembly 202 is located at the initial position of the air inlet cylinder 2021, the spring 2029 on the threaded rod 2026 is in a natural length or pre-tightened state, the abutment plate 2023 is in a corresponding position under the action of the spring 2029, and the worm wheel 1 2028 and the worm 1 2027 are not rotating. When preparing to start gastrointestinal endoscopy, firstly, the endoscope 2031 is fixedly connected to one end of the driving assembly 201 and inserted along the patient's oral cavity and throat. The design of the oblique insertion tube 2032 helps to guide the endoscope 2031 into the throat better, because its special oblique structure can adapt to the physiological curvature of the throat, reduce the resistance during insertion, and make the insertion process smoother; While inserting the endoscope tube 2031, the worm 1 2027 is rotated so that the air inlet cylinder 2021 can start to take in air through the air inlet hole 2025 of the mounting cylinder 2024. At this time, the oral cavity positioning part 204 slowly opens the oral cavity under the rotation of the worm 1 2027, providing necessary space for the insertion of the endoscope tube 2031 and avoiding the obstruction of the oral cavity tissue to the insertion of the endoscope tube 2031. Moreover, the opening state of the oral cavity positioning part 204 will affect the subsequent operation of the third positioning component, because the driving component 202 needs to adjust the fixed state of the endoscope component 203 according to the fixed state of the oral cavity positioning part 204.

[0049] When the endoscope tube 2031 is inserted to a certain position, in order to fix the endoscope assembly 203 in the throat, the driving assembly 202 needs to be started. The medical staff manually rotates the worm 1 2027.

[0050] Since the worm 2027 and the worm gear 2028 are connected by threads, according to the worm gear transmission principle, the rotation of the worm 2027 will drive the rotation of the worm gear 2028; the rotation of the worm gear 2028 will cause the threaded rod 2026 connected to it by threads to generate an axial movement. Since one end of the threaded rod 2026 is fixed with a slide plate 20210, and the threaded rod 2026 passes through and is rotationally connected to the air inlet cylinder 2021, when the threaded rod 2026 rotates, it will move along its axial direction. When the worm gear 2028 rotates clockwise, the threaded rod 2026 will axially move in the air inlet cylinder 2021, pushing the slide plate 20210 to slide on the inner wall of the air inlet cylinder 2021. As the threaded rod 2026 axially moves, the abutting plate 2023 sleeved on the threaded rod 2026 will also move accordingly. At this time, the spring 2029 will be compressed. At the same time, the mounting cylinder 2024 can introduce gas through the air inlet hole 2025. When the slide plate 20210 slides past the air outlet hole 2022 and approaches the side of the abutting plate 2023, the gas can be transmitted to the airbag 2033 through the air outlet hole 2022; During the adjustment of the second driving assembly 202, the airbag 2033 is inflated through the connecting pipe 2034. After inflation, the airbag 2033 will expand in the throat tube, making it closely fit with the inner wall of the throat tube, realizing the fixation of the endoscope tube 2031, preventing the endoscope tube 2031 from moving during the inspection process, and ensuring the stability and accuracy of the endoscopic operation; When the gastroscopy is completed, first, the gas in the airbag 2033 is discharged through the connecting pipe 2034 to make the airbag 2033 contract, releasing the fixation of the endoscope tube 2031. Then, the endoscope tube 2031 is slowly removed from the throat tube, and the worm 2027 is rotated in the reverse direction, driving the worm gear 2028 and the threaded rod 2026 to move in the reverse direction, making the slide plate 20210 reset on the inner wall of the air inlet cylinder 2021. The abutting plate 2023 returns to the initial position under the elastic restoring force of the spring 2029, making the entire second driving assembly 202 return to the initial state.

[0051] In summary, through the cooperation of the second driving assembly 202 and the endoscope assembly 203, by utilizing the worm gear transmission and the elastic action of the spring 2029, the fixed state of the endoscope tube 2031 in the throat tube can be accurately adjusted, enabling the device to adaptively adjust according to the physiological structure of the throat tubes of different patients and the state of the oral positioning part 204, improving the adaptability of the device and the stability of fixation, ensuring the stability of the position of the endoscope tube 2031 during the inspection process, and being conducive to improving the accuracy and safety of the inspection.

[0052] The inflation and fixation method of the airbag 2033 avoids the damage that traditional rigid fixation may cause to the throat tube tissue. By the soft contact and sealing with the inner wall of the throat tube, it reduces the compression and damage to the patient's throat tube, and improves the comfort and safety of the patient.

[0053] The second driving component 202 cooperates with the endoscope component 203 and the oral positioning part 204, ensuring the coordinated operation of the entire device during gastroscopy and colonoscopy examinations, achieving seamless connection and coordinated operation from the oral cavity to the larynx, and providing complete and stable positioning and operation conditions for the examination.
