Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a device for removing foreign bodies from the larynx in the field of otolaryngology. Background Technology

[0002] In otolaryngology clinical practice, foreign body obstruction of the larynx is one of the most common emergencies. The types of foreign bodies involved are diverse, including nuts, fish bones, metal fragments, jelly, etc. It can occur in different groups of people, such as adults, children and the elderly. As an important passage for breathing and swallowing, the larynx is prone to obstruction by foreign bodies. This can cause symptoms such as pain when swallowing and hoarseness. In severe cases, it can lead to difficulty breathing or even suffocation. If not treated promptly and effectively, it may endanger the patient's life.

[0003] The core requirements for larynx foreign body removal are to accurately locate and grasp the foreign body to prevent it from shifting or falling out during the procedure and causing secondary damage, to provide necessary care for the affected area of ​​the larynx before and after the foreign body removal to reduce the risk of infection, and to ensure a clear view of the larynx during the procedure to provide good operating conditions for medical staff.

[0004] Currently, existing technologies for removing foreign bodies from the larynx have significant shortcomings and fail to meet the comprehensive needs of clinical diagnosis and treatment. Most removal tools only have a single gripping function, and the gripping angle is fixed, making it difficult to adjust flexibly according to the actual position of the foreign body in the larynx. For foreign bodies that are hidden or have unusual shapes, it is often difficult to achieve precise gripping, resulting in a low success rate and even the possibility of scratching the laryngeal mucosa during the operation. Furthermore, existing laryngeal foreign body removal devices often only have a single gripping function, and the gripping process can easily cause damage to the affected area, lacking subsequent disinfection and care of the affected area. Summary of the Invention

[0005] In view of the fact that most existing foreign body removal tools only have a single clamping function and a fixed clamping angle, it is difficult to flexibly adjust according to the actual position of the foreign body in the throat. For foreign bodies that are hidden or have special shapes, it is often difficult to achieve precise clamping, resulting in a low success rate of removal and even the possibility of scratching the laryngeal mucosa during the operation. The purpose of this invention is to provide an ENT foreign body removal device.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An ENT foreign body removal device includes a handheld rod with a clamping mechanism at its bottom. The clamping mechanism includes an upper clamp and a lower clamp, which work together to clamp foreign bodies lodged in the throat from multiple angles. A medication application component is provided inside the handheld rod for disinfecting and applying medication to the area in the throat where the foreign body is lodged. A spreading component is provided on the bottom side wall of the handheld rod for spreading the throat open.

[0008] Optionally, the clamping mechanism includes a vertical through hole in the hand handle, a pull rod slidably installed in the through hole, a lower clamping plate fixedly installed at the bottom end of the pull rod, a pull rope fixedly installed at the end of the pull rod away from the lower clamping plate, an upper clamping plate fixedly installed at the bottom end of the hand handle that cooperates with the lower clamping plate, matching limiting grooves respectively opened on the upper clamping plate and the lower clamping plate, a fixing ring fixedly installed in the through hole, a first spring fixedly installed at the bottom end of the fixing ring, the end of the first spring away from the fixing ring being fixedly connected to the top end of the pull rod, and a light provided at the bottom end of the lower clamping plate.

[0009] Optionally, a self-locking assembly is provided inside the perforation. The self-locking assembly includes a pair of rotating shafts fixedly installed on the inner wall of the perforation. A locking plate is rotatably installed on the rotating shaft. The locking plate has a slot that cooperates with the pull rope. The pull rope passes through the fixing ring. The two locking plates are located on both sides of the pull rope. The locking plate is provided with a spring piece. The end of the spring piece away from the locking plate is connected to the inner wall of the perforation. The pair of rotating shafts are located above the fixing ring.

[0010] Optionally, a pull tube is slidably installed inside the perforation, the pull tube is located above the two clamping plates, the pull rope passes through the pull tube, a connecting rod is fixedly installed at the bottom end of the pull tube, and an abutment ring for pushing the clamping plates is fixedly installed at the end of the connecting rod away from the pull tube.

[0011] Optionally, the medication application assembly includes a storage cavity formed within a handheld handle, the storage cavity surrounding the perforation, and a partition plate within the storage cavity dividing the interior of the storage cavity into two chambers. A through hole communicating with the storage cavity is formed within the handheld handle, the through hole being located below the storage cavity. A piston plate is slidably installed within the storage cavity, and a push rod is fixedly installed on the piston plate.

[0012] Optionally, one cavity is filled with disinfectant, while the other cavity is filled with medicine.

[0013] Optionally, a pair of second springs are fixedly installed on the inner wall of the through hole, and a sealing plate is fixedly installed on the other end of the second springs. The sealing plate is slidably connected to the inner wall of the through hole.

[0014] Optionally, a positioning shaft is fixedly installed on the sealing plate, and a dispersing blade is rotatably installed on the positioning shaft.

[0016] Optionally, a ball bearing is rotatably mounted at the bottom end of the support plate.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above solution, by setting up a clamping mechanism, the upper and lower clamping plates can be used to clamp foreign objects stuck in the throat from different angles, breaking the limitation of clamping from a single angle. The clamping direction can be flexibly adjusted according to the actual position of the foreign object in the throat, thereby improving the success rate of foreign object clamping.

[0019] By incorporating a medication application component integrated into the handheld handle, precise disinfection and medication application can be performed on the area where the foreign object is lodged in the throat before and after removal. This prevents infection during the removal process and provides medication to treat minor injuries to the throat caused by the foreign object, promoting throat recovery.

[0020] By incorporating a dispersing component, which is mounted on the handheld handle, the dispersing component can appropriately open the throat before foreign body retrieval and medication application, fully exposing the affected area to the operator's view. This allows the operator to clearly observe the location and condition of the foreign body and the throat, providing favorable conditions for subsequent precise operations.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0038] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0039] Generally, terms can be understood at least partly from their use in context.

[0042] like Figures 1 to 8As shown, this embodiment of the invention provides an ENT foreign body removal device, including a hand handle 10, one end of which is connected to a clamping mechanism 20. The upper clamping plate 24 and the lower clamping plate 23 included in the clamping mechanism 20 cooperate to clamp foreign bodies stuck in the throat from multiple angles.

[0043] The handheld lever 10 contains a medication application component 40, which is used to disinfect and apply medication to the area where a foreign object is stuck in the throat. A spreading component 50 is located on the side wall of the handheld lever 10 near the gripping mechanism 20. This spreading component 50 is used to spread the throat open, facilitating observation of the affected area. This ENT foreign body removal device uses the handheld lever 10 as its core supporting component, providing the gripping base for the entire device. The gripping mechanism 20, through the coordinated action of the upper clamp 24 and the lower clamp 23, can grip foreign objects stuck in the throat from different angles, breaking the limitation of single-angle gripping and allowing for flexible gripping based on the actual position of the foreign object in the throat. The adjustable gripping direction improves the success rate of foreign object retrieval. The medication application component 40 is integrated inside the handheld lever 10, allowing for precise disinfection and medication application to the area where the foreign object is lodged in the throat before and after removal, preventing infection during the removal process. It also provides medication to treat minor injuries to the throat caused by the foreign object, promoting throat recovery. The opening component 50 is mounted on the handheld lever 10. Before foreign object retrieval and medication application, the opening component 50 can appropriately open the throat, fully exposing the affected area to the operator's view. This allows the operator to clearly observe the location and condition of the foreign object and the throat, providing favorable conditions for subsequent precise operations.

[0044] like Figures 1 to 6 As shown, the clamping mechanism 20 includes a through hole 21 formed in the handle 10, the through hole 21 extending through the handle 10 in the vertical direction, a pull rod 22 slidably installed in the through hole 21, the bottom end of the pull rod 22 extending out of the through hole 21, a lower clamping piece 23 fixedly installed at the bottom end of the pull rod 22, a pull rope 25 fixedly installed at the end of the pull rod 22 away from the lower clamping piece 23, the end of the pull rope 25 extending out of the through hole 21, and an upper clamping piece 24 that cooperates with the lower clamping piece 23 fixedly installed on the side wall at the bottom of the handle 10. The clip is circular and surrounds the outer periphery of the end of the handheld rod 10. The bottom end of the upper clip 24 and the top end of the lower clip 23 are both provided with matching limiting grooves 26 around the periphery. A fixing ring 28 is fixedly installed in the through hole 21. The pull rope 25 passes through the fixing ring 28. A first spring 27 is fixedly installed at one end of the fixing ring 28. The end of the first spring 27 away from the fixing ring 28 is fixedly connected to the pull rod 22. A light is provided at the bottom end of the lower clip. Similar to the throat foreign body removal device integrating a flashlight device, this is existing technology and will not be described in detail here.

[0045] When the clamping mechanism 20 is working, the light is turned on to provide good lighting for the clamping process. The operator drives the pull rod 22 to slide in the through hole 21 of the hand handle 10 by controlling the pull rope 25. When the pull rope 25 is pulled, the pull rod 22 will drive the lower clamping plate 23 to move closer to the upper clamping plate 24. The upper clamping plate 24 and the lower clamping plate 23 cooperate with each other to clamp the foreign object in the throat. During the clamping process, the limiting groove 26 opened on the upper clamping plate 24 and the lower clamping plate 23 can limit the foreign object and prevent it from slipping during the clamping process, thus ensuring the stability of the clamping.

[0046] The fixing ring 28, which is fixedly installed inside the perforation 21, provides installation support for the first spring 27. When the pull rope 25 is released, under the elastic restoring force of the first spring 27, the pull rod 22 will drive the lower clamping plate 23 to reset, so as to perform the next clamping operation or release the foreign object. This structure realizes convenient control and automatic reset of the clamping action, and improves the operating efficiency.

[0047] A self-locking assembly 30 is provided inside the perforation 21. The self-locking assembly 30 includes a pair of rotating shafts 31, which are mounted on the inner wall of the perforation 21. A locking plate 32 is rotatably mounted on the rotating shaft 31. The locking plate 32 has a slot 33 that cooperates with the pull rope 25. A spring piece 34 is fixedly mounted on the locking plate 32. The end of the spring piece 34 away from the locking plate 32 is fixedly connected to the inner wall of the perforation 21. Under the action of the spring piece 34, the two locking plates 32 have a tendency to clamp the pull rope 25.

[0048] During the process of the lower clamping plate 23 moving to grab the foreign object driven by the pull rod 22, the pull rope 25 will move within the perforation 21. Due to the pulling force, the pull rope 25 can move between the two clamping plates 32. When it is clamped to a suitable position and needs to be fixed, the pull rope 25 is released, the pulling force disappears, and the clamping plate 32 installed in the perforation 21 through the rotating shaft 31 clamps the pull rope 25 under the elastic force of the spring piece 34. The slot 33 on the clamping plate 32 will tightly engage with the pull rope 25, thereby fixing the pull rope 25, thus keeping the pull rod 22 and the lower clamping plate 23 in the current position, realizing self-locking, effectively avoiding the pull rope 25 from loosening due to factors such as hand tremors during operation, and ensuring the stability after the foreign object is grabbed.

[0049] A pull tube 37 is slidably installed inside the perforation 21. A connecting rod 36 is fixedly installed at the bottom end of the pull tube 37. An abutment ring 35 for pushing the card plate 32 is fixedly installed at the end of the connecting rod 36 away from the pull tube 37. The pull rope 25 passes through the pull tube 37 and the abutment ring 35.

[0050] When the self-locking state needs to be released, the operator pushes the pull tube 37 to slide within the perforation 21. The connecting rod 36, fixedly installed on the pull tube 37, moves synchronously with the movement of the pull tube 37. The connecting rod 36 drives the abutment ring 35 to move towards the clamping plate 32. After the abutment ring 35 contacts the clamping plate 32, the operator continues to push the pull tube 37, which generates a thrust on the clamping plate 32, causing the clamping plate 32 to rotate around the rotating shaft 31, thereby compressing the spring 34. When the clamping plate 32 rotates to a certain angle, the clamping groove 33 separates from the pull rope 25, and the self-locking state is released. Under the action of the first spring 27, the pull rod 22 drives the lower clamping piece 23 to reset. This structure can achieve self-locking release with a simple pushing action, making operation convenient and ensuring the flexible use of the clamping mechanism 20.

[0051] The medication application assembly 40 includes a storage cavity 41, which is located within the upper half of the handle 10 and surrounds the upper half of the through hole 21. The storage cavity 41 is connected to a through hole 44, which is located within the lower half of the handle 10 and surrounds the lower half of the through hole 21. A piston plate 42 is slidably mounted within the storage cavity 41, and a push rod 43 is fixedly mounted on the piston plate 42. The top of the storage cavity 41 communicates with the outside, and the top end of the push rod 43 extends outside the storage cavity 41. The bottom end of the through hole 44 passes through the upper clamp 24 and communicates with the outside.

[0052] The storage cavity 41 of the medication application component 40 is used to store disinfectant and medication, providing a material basis for throat medication. When medication application is required, the operator pushes the push rod 43, which drives the piston plate 42 to slide within the storage cavity 41. The sliding of the piston plate 42 will generate pressure on the disinfectant or medication in the storage cavity 41, causing the disinfectant or medication to flow out through the through hole 44 on the hand lever 10 that communicates with the storage cavity 41, and then act on the area of ​​the throat that needs disinfection or medication. By controlling the pushing force and stroke of the push rod 43, the outflow of disinfectant or medication can be controlled to achieve precise medication application, meet different medication needs, and avoid medication waste.

[0053] A partition inside the storage chamber 41 divides it into two chambers. One chamber contains disinfectant, and the other contains medication. This allows the medication delivery assembly 40 to perform both disinfection and medication delivery functions simultaneously, eliminating the need for frequent changes to the storage container and improving operational efficiency. Both chambers are equipped with piston plates 42, each with a push rod 43 extending out of the chamber. In actual use, the operator can first push the push rod 43 corresponding to the chamber storing disinfectant, allowing the disinfectant to flow out through the through-hole 44 to disinfect the foreign object in the throat, killing any bacteria and preventing infection. After disinfection, the operator then pushes the push rod 43 corresponding to the chamber storing medication to deliver the medication to the affected area in the throat for treatment. The two functions work together seamlessly, providing comprehensive support for throat recovery.

[0054] like Figures 5 to 8 As shown, a pair of second springs 45 are fixedly installed on the inner wall of the through hole 44, and the other end of the second spring 45 is fixedly installed with the same sealing plate 46. The sealing plate 46 is slidably connected to the inner wall of the through hole 44.

[0055] The second spring 45, fixedly installed inside the through hole 44, provides elastic support for the sealing plate 46. The sealing plate 46 is slidably connected to the inner wall of the through hole 44. When no medication is being applied, the second spring 45 is in its natural state, keeping the sealing plate 46 within the through hole 44 and isolating the through hole 44 from the outside world. This effectively prevents leakage of disinfectant or medicine from the storage cavity 41, ensuring the purity and effectiveness of the medicine, and preventing contamination of the medicine when not in use. When the push rod 43 is pushed to increase the pressure inside the storage cavity 41, the pressure overcomes the elastic force of the second spring 45, pushing the sealing plate 46 to slide within the through hole 44, opening the through hole 44 and allowing the disinfectant or medicine to flow out smoothly. After the push rod 43 is stopped, the pressure inside the storage cavity 41 decreases, and under the elastic restoring force of the second spring 45, the sealing plate 46 returns to its original position, resealing the through hole 44.

[0056] A positioning shaft 47 is fixedly installed on the sealing plate 46, and a dispersing blade 48 is rotatably installed on the positioning shaft 47.

[0057] When disinfectant or medicine flows out of storage cavity 41 through through hole 44, the medicine will impact the dispersing blade 48, causing the dispersing blade 48 to rotate around positioning axis 47. The rotating dispersing blade 48 can fully disperse the outflowing disinfectant or medicine, so that the medicine is distributed in a more uniform and fine droplet form on the affected area of ​​the throat, increasing the contact area between the medicine and the throat tissue, improving the absorption efficiency of the medicine, thereby improving the disinfection and treatment effect, and avoiding the problem of uneven treatment caused by local accumulation of medicine.

[0058] like Figures 1 to 8 As shown, the expansion assembly 50 includes a pair of sliding grooves 51, which are formed on the side wall of the handheld rod 10. The sliding grooves are located below the storage cavity 41 and are set along the length of the vertical section of the through hole 44. A slide frame 52 is slidably installed in the sliding groove 51. The slide frame 52 is sleeved on the side wall of the handheld rod 10 and slidably connected to the sliding groove 51. A pair of expansion plates 53 are rotatably installed on the slide frame 52. The expansion plates 53 are provided with straight slots 56. A pair of fixing brackets 54 are fixed to the top of the upper clamping piece 24. A limiting rod 55 that cooperates with the straight slot 56 is rotatably installed in each fixing bracket 54. The two limiting rods 55 are respectively set in the two straight slots 56 and pass through the straight slots 56. A pair of electric telescopic rods 57 are provided at the top of the upper clamping piece 24. The output ends of the two electric telescopic rods 57 are fixedly connected to the slide frame 52. A ball bearing 58 is provided at the bottom of the expansion plate 53.

[0059] When the expansion assembly 50 is working, the electric telescopic rod 57 is activated. The output end of the electric telescopic rod 57 drives the slide 52 to slide within the groove 51 of the hand handle 10. During the sliding process, the slide 52 drives the expansion plate 53, which is rotatably connected to it, to move. The straight groove 56 on the expansion plate 53 cooperates with the limiting rod 55 rotatably installed in the fixed frame 54. The limiting rod 55 slides within the straight groove 56, which restricts and guides the movement trajectory of the expansion plate 53. As the slide 52 moves, the expansion plate 53 gradually unfolds under the action of the limiting rod 55, thereby opening the throat. By controlling the extension and retraction of the electric telescopic rod 57, the degree of opening of the expansion plate 53 can be precisely controlled to meet different throat conditions and operational needs. The electric drive method is more stable and labor-saving than the manual drive, improving the accuracy and convenience of the expansion operation.

[0060] A ball bearing 58 is rotatably mounted on the expansion plate 53, and the ball bearing 58 is located on the expansion plate 53 at the end away from the slide 52.

[0061] A ball bearing 58 is rotatably mounted on the end of the expansion plate 53 away from the slide 52. When the expansion plate 53 expands in the larynx and comes into contact with the larynx tissue, the ball bearing 58 can roll and rub against the larynx tissue. Compared with the expansion plate 53 directly sliding against the larynx tissue, the frictional force of rolling friction is smaller, which can effectively reduce the frictional damage of the expansion plate 53 to the larynx tissue, reduce the discomfort of the larynx tissue during the expansion process, and make the expansion action of the expansion plate 53 smoother, avoiding difficulties in the expansion operation or unnecessary damage to the larynx due to excessive frictional resistance.

[0062] The specific workflow of the technical solution provided by this invention is as follows:

[0063] When using this ENT foreign body removal device, the operator first holds the hand lever 10, aligns the device with the patient's larynx, and activates the electric telescopic lever 57. The output end of the electric telescopic lever 57 drives the slide 52 to slide within the slide groove 51. The slide 52 drives the expansion plate 53 to unfold. Under the guidance of the limiting rod 55 and the straight groove 56, the expansion plate 53 gradually unfolds. The ball bearings 58 on the expansion plate 53 roll into contact with the larynx tissue, opening the larynx and fully exposing the foreign body for observation.

[0064] After observing the location of the foreign object, the operator pulls the pull rope 25. The pull rope 25 causes the pull rod 22 to slide within the perforation 21. The pull rod 22 causes the lower clamping piece 23 to move closer to the upper clamping piece 24. The upper clamping piece 24 cooperates with the lower clamping piece 23 to clamp the foreign object through the limiting groove 26. At this time, the pull rope 25 is released. Under the action of the spring piece 34, the locking plate 32 in the self-locking assembly 30 engages with the pull rope 25 through the locking groove 33, achieving self-locking and preventing the foreign object from falling off.

[0065] If an infection risk is detected in the throat during the removal process, or if the throat is damaged after the foreign object is removed, disinfection and medication are required. Push the push rod 43 of the corresponding storage cavity 41. The push rod 43 drives the piston plate 42 to slide, squeezing the disinfectant or medicine in the storage cavity 41. The pressure overcomes the elasticity of the second spring 45, pushing the sealing plate 46 to slide and opening the through hole 44. When the medicine flows out, it impacts the dispersing blade 48. The dispersing blade 48 rotates around the positioning shaft 47, dispersing the medicine and applying it evenly to the affected area of ​​the throat.

[0066] After the foreign object is removed and medication is applied, push the pull tube 37. The pull tube 37, through the connecting rod 36, drives the abutment ring 35 to rotate the clamping plate 32, causing the clamping groove 33 to separate from the pull rope 25 and releasing the self-locking mechanism. Under the elastic restoring force of the first spring 27, the pull rod 22 drives the lower clamping plate 23 to reset. Then, the slide 52 is reset by the electric telescopic rod 57, the electric telescopic rod 57 is closed, and the expansion plate 53 is retracted, completing the entire throat foreign object removal and subsequent treatment operation.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
