Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and in particular to a transnasal endoscope with a nasal mucosa protection function. Background Art

[0002] Transnasal endoscopes are commonly used diagnostic and therapeutic instruments in otolaryngology, widely used for examination and surgery of nasal and sinus diseases. Common transnasal endoscopes primarily consist of a body, light source, and camera system. The body is typically made of a hard material with a smooth surface, facilitating insertion into the nasal cavity for examination and surgical procedures.

[0003] The prior art, with publication number CN111297313B, provides a transnasal endoscope comprising an outer sheath, an inner sheath, and an endoscope. The outer sheath comprises an outer sheath positioning sleeve, a fixed-radius sheath, and a guide elbow, connected in sequence; the inner sheath comprises an inner sheath positioning sleeve, a straight sheath, and a flexible elbow, connected in sequence; the endoscope comprises a body, a rigid lens, a flexible lens, and an objective lens, and utilizes flexible image and illumination fibers for image transmission and illumination.

[0004] The prior art with publication number CN113975074B provides a head positioning device for ENT detection and its use method, which includes a base and a telescopic rod. The top of the base is rotatably provided with a rotating seat, and the top of the telescopic rod is connected to a fixed frame via a mounting frame; the bottom of the fixed frame is rotatably provided with a bracket, and a movable frame is provided on the side of the fixed frame away from the telescopic rod. The outside of the movable frame is provided with a cover, and a plurality of telescopic rods are slidably provided in the middle of the movable frame, and a limit assembly is provided at one end of the telescopic rod; the bottom end of the bracket is provided with a plane mirror and an illumination lamp;

[0005] Both of the above-mentioned transnasal endoscopes in the prior art lack positioning parts between the catheter and the patient's nasal cavity: in traditional nasal endoscopy, due to the lack of an effective positioning system, there is an obvious gap between the guide rod (the insertion part of the endoscope) and the nasal cavity. This problem causes many serious defects during the inspection process. Specifically, since the outer sheath, inner sheath, and flexible elbow components of the endoscope cannot form a stable fit with the inner wall of the nasal cavity, the guide rod is likely to touch the nasal mucosa when inserted into the nasal cavity, which may cause discomfort to the patient even under anesthesia. When the flexible elbow of the endoscope enters the nasal cavity without positioning, its front end will involuntarily touch the inner wall of the nasal cavity, causing the patient to feel tingling or discomfort, which in turn causes the patient to feel nervous and resistant, and even causes the patient's head to shake unconsciously. This shaking will not only intensify the friction between the guide rod and the nasal mucosa, but may also cause minor damage to the nasal mucosa, increasing the risk of bleeding.

[0006] Furthermore, due to a lack of positioning, the endoscope's objective lens cannot accurately align with the lesion within the nasal cavity, causing doctors to miss important details during observation and affecting diagnostic accuracy. When examining the nasal cavity of a patient with sinusitis, the unstable guide rod may prevent the objective lens from accurately aligning with the sinus opening, preventing doctors from clearly observing the lesion and delaying treatment.

[0007] At the same time, this gap will also cause negative pressure to form in the nasal cavity, affecting the patient's breathing comfort and further aggravating the patient's discomfort.

[0008] Therefore, traditional nasal endoscopes without a positioning system not only reduce the accuracy and safety of the examination, but also increase the patient's pain and the risk of complications. Summary of the Invention

[0009] In view of the deficiencies of the prior art, the present invention provides a transnasal endoscope with a nasal mucosa protection function, which solves the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] Transnasal endoscopes with nasal mucosa protection function include:

[0012] A guide rod, one end of which is equipped with a camera and the other end of which is connected to a display screen via a wire communication, and a fill light is fixedly installed at the end of the guide rod and located outside the camera;

[0013] The protective sleeve is movably mounted on the outside of the guide rod and is used to be inserted into the patient's nostrils; the inner wall of the protective sleeve and the outer wall of the guide rod are sprayed with a super-slip layer;

[0014] An annular airbag, which is fixedly mounted on the outside of the protective cover;

[0015] An air supply assembly is mounted on the protective cover and connected to the annular airbag, and is used to supply air to the annular airbag;

[0016] The restraint assembly includes a base plate and two vertical plates symmetrically fixedly mounted on the top of the base plate. A square airbag is fixedly mounted on one side of the vertical plate and the other side of the vertical plate, and both square airbags are connected to the air supply assembly;

[0017] A positioning piece is installed on the protective sleeve and can be connected to the guide rod to position or cancel the positioning between the guide rod and the protective sleeve; the positioning piece includes a positioning frame fixedly installed on the protective sleeve, a positioning rod is provided on the positioning frame and is movable along the direction of the guide rod, a rubber pad is fixedly installed on the side of the positioning rod close to the guide rod, a limiting plate is fixedly installed on the end of the positioning rod away from the rubber pad, a spring is provided on the outer sleeve of the positioning rod, and the two ends of the spring respectively conflict with the positioning frame and the limiting plate, a positioning plate is fixedly installed on the protective sleeve and on the side of the positioning frame away from the guide rod, and when the rubber pad conflicts with the guide rod, the limiting plate can conflict with the side of the positioning plate close to the positioning frame.

[0018] The present invention provides a transnasal endoscope with nasal mucosal protection function. Compared with the existing technology, it has the following advantages:

[0019] 1. By setting up two square airbags to clamp and position the patient's head, and at the same time making the annular airbag expand and form a conflict with the inside of the patient's nostrils, the protective sleeve is limited, and the guide rod is effectively limited. This design can effectively avoid the gap between the guide rod and the nasal cavity, and significantly reduce the shaking of the guide rod in the nasal cavity. Therefore, when performing a nasal endoscope examination on the patient, it can effectively avoid the patient's discomfort or head shaking caused by the shaking of the guide rod, reduce the friction between the end of the guide rod and the nasal mucosa in the patient's nasal cavity, reduce damage to the nasal mucosa, and achieve a protective effect on the nasal mucosa.

[0020] 2. The positioning piece can connect the protective cover and the guide rod together when not in use or in the early stage of endoscope insertion for synchronous operation. When the protective cover is inserted into the patient's nasal cavity, the positioning piece is unlocked to separate the protective cover and the guide rod, and the guide rod can be inserted separately.

[0021] 3. By spraying an ultra-slip layer on both the inner wall of the protective sleeve and the outer wall of the guide rod, using a Class II ultra-slip material such as polytetrafluoroethylene (PTFE), the friction between the guide rod and the protective sleeve is significantly reduced. This design not only facilitates the smooth sliding of the guide rod on the protective sleeve, but also reduces friction between the guide rod and the nasal mucosa when the guide rod is inserted into the patient's nasal cavity, further reducing irritation and damage to the nasal mucosa, improving patient comfort and examination safety.

[0022] 4. By combining head clamping and positioning with nasal cavity limiting functions, and utilizing a super-slip layer, the present invention significantly improves the efficiency and stability of nasal endoscopic examinations. This reduces discomfort and anxiety for patients during the examination, and reduces the need for interruptions or repeated procedures due to head shaking, thereby improving the success rate and efficiency of the examination.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] In order to solve the technical problems in the background technology, the following nasal endoscope with nasal mucosa protection function is provided:

[0046] Combine Figure 1 - Figure 10 As shown, the nasal endoscope with nasal mucosa protection function provided by the present invention includes:

[0047] The guide rod 1 has a camera 11 mounted on one end and a display screen 14 connected to the other end via a wire 13. A fill light 12 is fixedly mounted on the end of the guide rod 1 and located outside the camera 11. Specifically, a lens is fixed on the end of the guide rod 1 and located outside the fill light 12 and the camera 11.

[0048] A protective sleeve 2 is movably mounted on the outside of the guide rod 1 and is used to be inserted into the patient's nostrils;

[0049] An annular airbag 3, which is fixedly mounted on the outside of the protective cover 2;

[0050] An air supply assembly 4 is mounted on the protective cover 2 and connected to the annular airbag 3. The air supply assembly 4 is used to supply air to the annular airbag 3.

[0051] The restraint assembly 5 includes a base plate 51 and a vertical plate 1 52 and a vertical plate 2 54 symmetrically fixedly mounted on the top of the base plate 51. A square airbag 53 is fixedly mounted on the side of the vertical plate 1 52 and the vertical plate 2 54 close to each other, and both square airbags 53 are connected to the air supply assembly 4;

[0052] The positioning member 6 is mounted on the protective cover 2 and can be connected to the guide rod 1 . The positioning member 6 is used to position or cancel the positioning between the guide rod 1 and the protective cover 2 .

[0053] When performing a nasal endoscopy on a patient, first position the protective cover 2 and the guide rod 1 through the positioning member 6, place the bottom plate 51 on the bed, and when the patient lies flat on the bed, position the patient's head between the two square airbags 53, and inflate the inside of the two square airbags 53 through the air supply component 4 to deform the two square airbags 53, so that the opposite sides of the two square airbags 53 are engaged with each other, so that the two square airbags 53 clamp and position the patient's head. When the end of the guide rod 1 away from the wire 13 is inserted into the patient's nostril for inspection, the annular airbag 3 is driven by the protective cover 2 to be inserted into the inside of the patient's nostril. At this time, the annular airbag 3 is inflated through the air supply component 4. , so that the annular airbag 3 expands and comes into conflict with the inside of the patient's nostril, thereby limiting the protective cover 2 and achieving the limiting effect on the guide rod 1, thereby effectively avoiding the situation where a gap exists between the guide rod 1 and the nasal cavity when the guide rod 1 is inserted into the nasal cavity during nasal endoscopy of the patient, and the patient's head is clamped and positioned by the two square airbags 53, effectively avoiding the situation where the guide rod 1 causes discomfort to the patient and causes the patient's head to shake when the guide rod 1 is inserted into the nasal cavity during nasal endoscopy of the patient, thereby effectively reducing the friction between the end of the guide rod 1 and the nasal mucosa in the patient's nasal cavity, reducing the damage to the nasal mucosa in the patient's nasal cavity, and achieving the effect of protecting the nasal mucosa.

[0054] In this embodiment, the air supply component 4 includes an air guide tube 41 that passes through the protective sleeve 2 and is connected to the annular airbag 3. The other end of the air guide tube 41 is fixedly connected to a ventilation tube 42. The other end of the ventilation tube 42 is fixedly connected to a connecting tube 43 and a connecting tube 44 through a three-way joint. The end of the connecting tube 43 away from the three-way joint is fixedly connected to an airbag ball 45 connected thereto. Specifically, it should be noted that an exhaust valve is provided on the airbag ball 45. The airbag ball 45 is an existing structure and belongs to the well-known technical scope of those skilled in the art. It will not be described in detail here. Two air guide tubes 46 that are both connected thereto are fixedly installed on the connecting tube 43. The other ends of the two air guide tubes 46 are respectively connected to the two square airbags 53. A valve 421 is fixedly installed on the ventilation tube 42 to connect A valve 2 441 is fixedly installed on the tube 44 and on one side of the two air guide tubes 2 46 near the three-way joint. When in use, when supplying air to the two square air bags 53, the valve 1 421 is controlled to be closed and the valve 2 441 is opened. The air bag ball 45 is continuously squeezed and pressed to transport gas into the connecting tube 43. When the gas flows, the gas is transported to the two air guide tubes 2 46 through the three-way joint and the connecting tube 43, thereby achieving the effect of supplying air to the two square air bags 53; similarly, when supplying air to the annular air bag 3, the valve 2 441 is controlled to be closed and the valve 1 421 is opened. The air bag ball 45 is continuously squeezed and pressed to transport gas into the connecting tube 43. When the gas flows, the gas is circulated through the three-way joint, the ventilation tube 42 and the air guide tube 1 41 to the annular air bag 3, which is easy to operate.

[0055] In this embodiment, the inner wall of the protective sleeve 2 and the outer wall of the guide rod 1 are sprayed with a super-slip layer. The super-slip layer adopts polyfluorotetraethylene type II super-slip material, which reduces the friction between the guide rod 1 and the protective sleeve 2, facilitates the sliding of the guide rod 1 on the protective sleeve 2, and reduces the friction between the guide rod 1 and the nasal mucosa in the patient's nasal cavity when the guide rod 1 is inserted into the inside of the patient's nasal cavity, thereby reducing damage to the nasal mucosa. The positioning member 6 includes a positioning frame 61 fixedly mounted on the protective sleeve 2, and a positioning rod 62 is provided on the positioning frame 61 and is movable along the direction of the guide rod 1. The positioning rod 62 is fixedly mounted on one side of the guide rod 1. There is a rubber pad 63, and one end of the positioning rod 62 away from the rubber pad 63 is fixedly installed with a limit plate 64. The outer sleeve of the positioning rod 62 is provided with a spring 65. The two ends of the spring 65 respectively conflict with the positioning frame 61 and the limit plate 64. A positioning plate 66 is fixedly installed on the protective sleeve 2 and on the side of the positioning frame 61 away from the guide rod 1. When the rubber pad 63 conflicts with the guide rod 1, the limit plate 64 can conflict with the side of the positioning plate 66 close to the positioning frame 61. When in use, when the positioning between the guide rod 1 and the protective sleeve 2 is cancelled, the limit plate 64 is pushed to drive the positioning rod 62 to slide on the positioning frame 61, so that the rubber The pad 63 conflicts with the guide rod 1, the limit plate 64 is located on the side of the positioning plate 66 close to the positioning frame 61, and the spring 65 is deformed. At this time, the positioning rod 62 is rotated on the positioning frame 61 through the limit plate 64, so that the limit plate 64 can conflict with the side of the positioning plate 66 close to the positioning frame 61, and the force on the limit plate 64 is canceled. The spring 65 returns to its natural state, so that the limit plate 64 conflicts with the side of the positioning plate 66 close to the positioning frame 61, and the rubber pad 63 conflicts with the guide rod 1, thereby achieving the positioning effect between the protective cover 2 and the guide rod 1; the force on the protective cover 2 and the guide rod 1 is canceled. When positioning between the two, a force is applied to the limit plate 64, which causes the positioning rod 62 to rotate on the positioning frame 61 through the limit plate 64, so that the limit plate 64 is located outside the positioning plate 66. At this time, the force on the limit plate 64 is cancelled, and the spring 65 returns to its natural state, thereby driving the positioning rod 62 to slide and reset in the positioning frame 61 through the limit plate 64. The rubber pad 63 does not contact the guide rod 1, thereby canceling the positioning between the protective cover 2 and the guide rod 1, which is convenient for operation. The design of the rubber pad 63 avoids hard contact between the positioning rod 62 and the guide rod 1, which causes wear of the super-slip layer on the surface of the guide rod 1.

[0056] Example 2

[0057] like Figure 1 - Figure 10 As shown, based on the above embodiment, this embodiment further provides the following content:

[0058] In this embodiment, the outer wall of the annular airbag 3 forms a wavy profile, and a liquid suction component 7 connected to the protective cover 2 is installed on the bottom plate 51. The liquid suction component 7 includes a waste liquid tank 71 fixedly installed on the bottom plate 51, and a negative pressure pump 72 connected to the interior of the waste liquid tank 71 is fixedly installed on the waste liquid tank 71. A liquid suction pipe 73 connected to the interior of the waste liquid tank 71 is fixedly installed in the middle position of one side of the waste liquid tank 71. A through hole 21 is opened on the protective cover 2 and located on the outside of the guide rod 1. The liquid suction pipe 73 is connected to the interior of the waste liquid tank 71. The other end of the waste liquid tank 71 passes through the through hole 1 21 and is fixedly connected to the protective cover 2. A liquid filling port communicating with the interior of the waste liquid tank 71 is provided on the top. A sealing cover for sealing the liquid filling port is detachably mounted on the waste liquid tank 71. A liquid discharge valve communicating with the inner bottom wall of the waste liquid tank 71 is fixedly mounted on one side of the waste liquid tank 71. By setting the liquid suction component 7, when the protective cover 2 is inserted into the inside of the patient's nostril during nasal endoscopic examination, the through hole 1 21 is located directly below the guide rod 1, and the liquid suction tube The end 73 is connected to the inside of the patient's nostril. When there is nasal mucus in the patient's nostril, the negative pressure pump 72 is controlled to start, and the negative pressure pump 72 draws out the air in the waste liquid tank 71, so that negative pressure is formed in the waste liquid tank 71, thereby allowing the air in the patient's nostril to enter the suction tube 73. Since the through hole 121 is located just below the guide rod 1, the end of the suction tube 73 is located at the bottom wall of the patient's nostril, so that the nasal mucus in the patient's nostril can be sucked into the waste liquid tank 71 through the suction tube 73, achieving the purpose of The cleaning effect of the nasal mucus in the patient's nostrils; by setting the outer wall of the annular airbag 3 to form a wavy profile, there are multiple gaps between the outer wall of the annular airbag 3 and the inner wall of the patient's nostrils, which effectively avoids the formation of negative pressure inside the patient's nostrils. By setting the drain valve, it is beneficial to discharge the waste liquid in the waste liquid tank 71. Through the liquid filling port and the sealing cover, the sealing cover is used to achieve the sealing of the liquid filling port, and it is convenient to pour liquid into the waste liquid tank 71 through the liquid filling port, thereby facilitating the flushing of the inside of the waste liquid tank 71.

[0059] In this embodiment, a cleaning component 8 connected to the protective cover 2 is installed on the bottom plate 51. It can be understood that the cleaning component 8 is used to disinfect the nasal cavity after the inspection is completed, and at the same time, pre-clean and disinfect the endoscope to protect the normal function of the nasal mucosa. In specific implementation, the cleaning component 8 includes a liquid storage tank 81 fixedly installed on the bottom plate 51, and a liquid pump 82 connected to the inner bottom wall of the liquid storage tank 81 is fixedly installed on the liquid storage tank 81. The liquid outlet end of the liquid pump 82 is fixedly installed with a liquid pipe 83 connected to it. A through hole 22 is provided on the protective cover 2 and is located on the side of the guide rod 1 away from the through hole 1 21. The other end of the liquid pipe 83 passes through the through hole 22 and is fixedly connected to the protective cover 2. A liquid injection port connected to the interior of the liquid storage tank 81 is provided on the top of the liquid storage tank 81. The box 81 is detachably provided with a sealing cap for sealing the liquid injection port. When in use, the sealing cap is removed and disinfectant can be poured into the liquid storage box 81 through the liquid injection port. By designing the cleaning component 8, when the protective cover 2 is inserted into the inside of the patient's nostril, the through hole 1 21 is located just above the guide rod 1. After the nasal endoscopy of the patient is completed, when the guide rod 1 is pulled out, the liquid pump 82 is controlled to work to extract the disinfectant in the liquid storage box 81, thereby delivering it to the liquid passage 83 and passing through the other end of the liquid passage 83. The liquid flows out, thereby dripping onto the guide rod 1 and then flowing to the inside of the patient's nostril, achieving the effect of pre-cleaning and disinfecting the guide rod 1 and rinsing the inside of the patient's nostril. During this period, the negative pressure pump 72 is controlled to simultaneously absorb and clean the waste liquid dripping into the patient's nostril. In addition, after the nasal endoscope examination of the patient is completed, the guide rod 1 is pulled out so that the end of the guide rod 1 is located inside the nostril. The positioning member 6 is used to position the protective cover 2 and the guide rod 1, and the gas in the annular airbag 3 is discharged to cancel the positioning of the protective cover 2, thereby achieving the positioning of the protective cover 2 through the guide rod 1. When the disinfectant is sprayed, the guide rod 1 drives the protective cover 2 to move. With the cooperation of the guide rod 1 and the camera 11, the disinfectant can be accurately sprayed to a specific area in the nostril, ensuring that the disinfectant can evenly cover the area to be disinfected. The precise positioning avoids blind spraying of the disinfectant in the nasal cavity. Similarly, with the cooperation of the guide rod 1 and the camera 11, the opening of the suction tube 73 can be accurately aligned with the specific area in the nostril, thereby more effectively removing the liquid.

[0060] In this embodiment, a limiting frame 511 with an open top is fixedly installed on the top of the base plate 51, and the airbag ball 45 can be placed in the limiting frame 511. By setting the limiting frame 511, the airbag ball 45 can be limited and stored. A supporting mechanism 9 is installed on the side of the vertical plate 1 52 away from the vertical plate 2 54, and the display screen 14 is placed on the supporting mechanism 9. Through the design of the supporting mechanism 9, the positioning effect of the display screen 14 is achieved, which is convenient for medical staff to watch.

[0061] Example 3

[0062] like Figure 1 - Figure 10 As shown, based on the above embodiment, this embodiment further provides the following content:

[0063] 92 is rotatably mounted on the mounting plate 91, and a support plate 93 is rotatably mounted on the mounting plate 91 via a rotating shaft 92. A connecting column 94 is fixedly mounted on the top of the support plate 93, and a fixing plate 95 is ball-connected to the top of the connecting column 94. Specifically, it should be noted that the rotating shaft 92 is fixedly connected to the support plate 93, the rotation between the rotating shaft 92 and the mounting plate 91 is damped, and the rotation between the fixing plate 95 and the connecting column 94 is damped. A mounting groove 951 is provided on one side of the fixing plate 95, and the display screen 14 is fixedly mounted in the mounting groove 951. The support plate 93 is rotatably mounted on the mounting plate 91 via the rotating shaft 92, and the fixing plate 95 is ball-connected to the connecting column 94. When in use, medical personnel can use the support plate 93 to rotate the rotating shaft 92 on the mounting plate 91, and then rotate the fixing plate 95 around the connecting column 94, thereby adjusting the inclination direction of the fixing plate 95 to facilitate medical personnel to watch the display screen 14.

[0064] In this embodiment, the mounting plate 91 is hinged to one side of the vertical plate 52 by the hinge shaft 911. When the mounting plate 91 is in a vertical state, the support plate 93 can be fitted with the top of the vertical plate 52, and the fixing plate 95 can be fitted with the top of the vertical plate 2 54. An adjusting member for driving the hinge shaft 911 to rotate or stop rotating is installed on the vertical plate 52. The adjusting member includes a worm gear 912 and a worm 913. The worm gear 912 is coaxially fixed to the hinge shaft 911. The worm 913 is rotatably mounted on the vertical plate 52 and meshed with the worm gear 912. By setting the mounting plate 91 to be hinged to one side of the vertical plate 52 by the hinge shaft 911, when in use, the rotating worm 913 is driven by the worm gear 912 The movable hinge shaft 911 rotates on one side of the vertical plate 1 52, further increasing the adjustment range of the tilt direction of the fixed plate 95, which is further beneficial for medical personnel to watch the display screen 14. When not in use, the mounting plate 91 is driven to rotate around the hinge shaft 911 to a vertical state by rotating the worm gear 913, and the rotating shaft 92 is rotated horizontally on the mounting plate 91 through the support plate 93, so that the fixed plate 95 can be fitted with the top of the vertical plate 2 54, reducing the overall height of the support mechanism 9, making it easier to store the device. In addition, during this period, the fixed plate 95 can be rotated to a horizontal state, and the mounting groove 951 is located at the bottom of the fixed plate 95, thereby achieving a protective effect on the display screen 14.

[0065] The support plate 93 is provided with a through hole 931 for the annular airbag 3 to pass through.
