The types of foreign bodies involved are diverse, including nuts, fish bones, metal fragments, jelly, etc. It can occur in different populations such as adults, children and the elderly. As an important passageway for breathing and swallowing, once foreign body obstruction occurs, it will not only cause patients to have symptoms such as swallowing pain and hoarseness, but also can cause severe respiratory difficulty and even asphyxia. If not treated in time and effectively, it may endanger the patient's life.

[0003] The core requirement of the foreign body removal operation in the larynx is to accurately position and clamp the foreign body, avoid displacement or falling of the foreign body during the operation process to cause secondary injury, and to provide necessary care to the larynx before and after the foreign body is removed to reduce the risk of infection, while ensuring a clear view of the larynx during the operation process to provide good operating conditions for medical personnel.

[0043] The hand-held rod 10 is internally provided with a medicine applying assembly 40, which is used for disinfecting and applying medicine to the part where the foreign body is stuck in the throat; the side wall of the hand-held rod 10 near one end of the clamping mechanism 20 is provided with a strutting assembly 50, which is used for strutting the throat, so as to facilitate strutting and observation of the affected part; the laryngeal foreign body removal device for otolaryngology takes the hand-held rod 10 as a core support component, and the hand-held rod 10 provides a holding basis for the whole device; the clamping mechanism 20 can perform clamping operation on the foreign body stuck in the throat from different angles by means of the cooperation of the upper clamping piece 24 and the lower clamping piece 23, breaks the limitation of single-angle clamping, can flexibly adjust the clamping direction according to the actual position of the foreign body in the throat, and improves the success rate of foreign body clamping; the medicine applying assembly 40 is integrated inside the hand-held rod 10, and can accurately perform disinfection and medicine applying operation on the part where the foreign body is stuck in the throat before and after the foreign body is removed, so as to avoid infection caused by the foreign body removal process, at the same time, medicine treatment is performed on the slight damage of the throat caused by the foreign body, so as to promote the recovery of the throat; the strutting assembly 50 is installed on the hand-held rod 10, and before the foreign body clamping and medicine applying operation are performed, the strutting assembly 50 can properly struts the throat, so that the affected part of the throat is fully exposed in the field of view of the operator, which facilitates the operator to clearly observe the position, state of the foreign body and the throat condition, and provides a good condition for subsequent accurate operation.

[0044] As shown in the Figures 1 to 6 The clamping mechanism 20 comprises a through hole 21 opened on the hand-held rod 10, the through hole 21 penetrates the hand-held rod 10 along the vertical direction of the hand-held rod 10, a pull rod 22 is slidingly installed in the through hole 21, the bottom end of the pull rod 22 extends out of the through hole 21, the bottom end of the pull rod 22 is fixedly installed with a lower clamping piece 23, the end of the pull rod 22 away from the lower clamping piece 23 is fixedly installed with a pull rope 25, the end of the pull rope 25 extends out of the through hole 21, the side wall of the bottom of the hand-held rod 10 is fixedly installed with an upper clamping piece 24 cooperating with the lower clamping piece 23, the upper clamping piece is circular and is arranged around the outer periphery of the end of the hand-held rod 10, the bottom end of the upper clamping piece 24 and the top end of the lower clamping piece 23 are both annularly provided with a limiting groove 26 matched therefor, a fixing ring 28 is fixedly installed in the through hole 21, the pull rope 25 penetrates the fixing ring 28, one end of the fixing ring 28 is fixedly installed with a first spring 27, the end of the first spring 27 away from the fixing ring 28 is fixedly connected with the pull rod 22, and the bottom end of the lower clamping piece is provided with a lighting lamp; the similar laryngeal foreign body removal device integrates a flashlight device, which is prior art and will not be described herein.

[0045] When the clamping mechanism 20 works, the lighting lamp is turned on to provide good lighting effect for the clamping process, and the operator drives the pull rod 22 to slide in the through hole 21 of the hand-held rod 10 by controlling the pull rope 25. When the pull rope 25 is pulled, the pull rod 22 drives the lower clamping piece 23 to move towards the upper clamping piece 24, and the upper clamping piece 24 cooperates with the lower clamping piece 23 to clamp the foreign matter in the throat. In the clamping process, the limiting groove 26 formed in the upper clamping piece 24 and the lower clamping piece 23 can limit the foreign matter to prevent the foreign matter from falling off during the clamping process, thereby ensuring the stability of clamping.

[0046] The fixed ring 28 fixedly installed in the through hole 21 provides mounting support for the first spring 27. When the pull rope 25 is loosened, the pull rod 22 drives the lower clamping piece 23 to reset under the elastic restoring force of the first spring 27, so as to perform the next clamping operation or loosen the foreign matter. The structure realizes convenient control and automatic reset of the clamping action, and improves the operation efficiency.

[0047] The through hole 21 is provided with a self-locking assembly 30. The self-locking assembly 30 includes a pair of rotating shafts 31 installed on the inner wall of the through hole 21. The rotating shafts 31 are rotatably installed with clamping plates 32. The clamping plates 32 are provided with clamping grooves 33 matched with the pull rope 25. The clamping plates 32 are fixedly installed with elastic sheets 34. The ends of the elastic sheets 34 away from the clamping plates 32 are fixedly connected with the inner wall of the through hole 21. Under the action of the elastic sheets 34, the two clamping plates 32 have a tendency to clamp the pull rope 25.

[0048] In the process of moving the lower clamping piece 23 by the pull rod 22 to clamp the foreign matter, the pull rope 25 moves in the through hole 21. Due to the action of the pulling force, the pull rope 25 can move between the two clamping plates 32. When clamping to the appropriate position needs to be fixed, the pull rope 25 is loosened, the pulling force disappears, the clamping plates 32 rotatably installed in the through hole 21 clamp the pull rope 25 under the elastic force of the elastic sheets 34, the clamping grooves 33 on the clamping plates 32 tightly clamp the pull rope 25, so as to fix the pull rope 25, and then the pull rod 22 and the lower clamping piece 23 are kept at the current position, realizing self-locking, effectively avoiding the loosening of the pull rope 25 caused by hand shaking and other factors in the operation process, and ensuring the stability after clamping the foreign matter.

[0049] The pull pipe 37 is slidably installed in the through hole 21. The connecting rod 36 is fixedly installed at the bottom end of the pull pipe 37. The abutting ring 35 for pushing the clamping plate 32 is fixedly installed at the end of the connecting rod 36 away from the pull pipe 37. The pull rope 25 penetrates the pull pipe 37 and the abutting ring 35.

[0050] When the self-locking state needs to be released, the operator pushes the pull tube 37 to slide in the through hole 21. The connecting rod 36 fixedly installed on the pull tube 37 will move synchronously with the movement of the pull tube 37, the connecting rod 36 drives the abutting ring 35 to move towards the clamping plate 32, after the abutting ring 35 contacts with the clamping plate 32, the operator continues to push the pull tube 37, the abutting ring 35 will generate a pushing force on the clamping plate 32, so that the clamping plate 32 rotates around the rotating shaft 31, thereby compressing the elastic sheet 34, when the clamping plate 32 rotates to a certain angle, the clamping groove 33 is separated from the pull rope 25, 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. The structure can realize the release of self-locking through a simple pushing action, the operation is convenient, and the flexible use of the clamping mechanism 20 is ensured.

[0051] The medicine applying assembly 40 comprises a storage cavity 41, the storage cavity 41 is arranged in the upper half of the handheld rod 10 and surrounds the upper half of the through hole 21, the storage cavity 41 is communicated with a through hole 44, the through hole 44 is arranged in the lower half of the handheld rod 10 and surrounds the lower half of the through hole 21, a piston plate 42 is slidably installed in the storage cavity 41, and a push rod 43 is fixedly installed on the piston plate 42; the top of the storage cavity 41 is communicated with the outside, and the top end of the push rod 43 extends to the outside of the storage cavity 41. The bottom end of the through hole 44 penetrates the upper clamping piece 24 and is communicated with the outside.

[0052] The storage cavity 41 of the medicine applying assembly 40 is used for storing disinfectant water and liquid medicine, and provides a material basis for throat medicine applying, when the medicine applying operation needs to be performed, the operator pushes the push rod 43, the push rod 43 drives the piston plate 42 to slide in the storage cavity 41, the sliding of the piston plate 42 generates a pressure on the disinfectant water or liquid medicine in the storage cavity 41, so that the disinfectant water or liquid medicine flows out through the through hole 44 of the handheld rod 10 which is communicated with the storage cavity 41, and then acts on the throat part which needs to be disinfected or applied with medicine, by controlling the pushing force and stroke of the push rod 43, the flow amount of the disinfectant water or liquid medicine can be controlled, precise medicine applying can be realized, different medicine applying requirements can be met, and medicine waste can be avoided.

[0053] The storage cavity 41 is provided with a partition plate to divide the storage cavity into two cavities, disinfectant water is arranged in one cavity, and liquid medicine is arranged in the other cavity; the medicine applying assembly 40 can simultaneously have disinfecting and medicine applying functions, the storage container does not need to be frequently replaced, the operation efficiency is improved, the piston plate 42 is arranged in each cavity, and the push rod 43 extending to the outside of the cavity is arranged at the top end of each piston plate 42, in actual use, the operator can push the push rod 43 corresponding to the cavity storing disinfectant water first, so that the disinfectant water flows out through the through hole 44, disinfects the foreign matter in the throat, kills possible bacteria, and prevents infection; after disinfection is completed, the push rod 43 corresponding to the cavity storing liquid medicine is pushed again, so that the liquid medicine is delivered to the throat part, and the throat injury is treated, the two functions are sequentially matched, and comprehensive guarantee is provided for throat recovery.

[0054] As shown in Figures 5 to 8 The inner wall of the through hole 44 is fixedly installed with a pair of second springs 45, the other end of the second spring 45 is fixedly installed with the same sealing plate 46, and the sealing plate 46 is in sliding connection with the inner wall of the through hole 44;

[0055] The second spring 45 fixedly installed in the through hole 44 provides elastic support for the sealing plate 46, the sealing plate 46 is in sliding connection with the inner wall of the through hole 44, when the medicine is not applied, the second spring 45 is in a natural state, the sealing plate 46 is maintained in the through hole 44, the through hole 44 is isolated from the outside, effectively preventing the disinfectant water or liquid medicine in the storage cavity 41 from leaking, ensuring the purity and effectiveness of the medicine, and avoiding the medicine from being contaminated in the non-use state, when the push rod 43 is pushed to increase the pressure in the storage cavity 41, the pressure will overcome the elastic force of the second spring 45, push the sealing plate 46 to slide in the through hole 44, open the through hole 44, and make the disinfectant water or liquid medicine flow out smoothly; after stopping pushing the push rod 43, the pressure in the storage cavity 41 decreases, and under the action of the elastic restoring force of the second spring 45, the sealing plate 46 resets to seal the through hole 44 again.

[0056] The sealing plate 46 is fixedly installed with a positioning shaft 47, and the positioning shaft 47 is rotatably installed with a scattering blade 48;

[0057] When the disinfectant water or liquid medicine flows out from the storage cavity 41 through the through hole 44, the liquid medicine will impact the scattering blade 48, causing the scattering blade 48 to rotate around the positioning shaft 47, and the rotating scattering blade 48 can fully scatter the flowing disinfectant water or liquid medicine, so that the medicine is distributed in the form of fine droplets on the affected part of the throat, increasing the contact area between the medicine and the throat tissue, improving the absorption efficiency of the medicine, and further improving the disinfection and treatment effect, avoiding the problem of uneven treatment caused by local accumulation of medicine.

[0058] As shown in Figures 1 to 8 The expansion assembly 50 includes a pair of sliding grooves 51, the sliding grooves 51 are opened on the side wall of the handheld rod 10, the sliding grooves are located below the storage cavity 41 and are arranged along the length of the vertical section of the through hole 44, the sliding grooves 51 are slidably installed with a sliding frame 52, the sliding frame 52 is sleeved on the side wall of the handheld rod 10 and is in sliding connection with the sliding grooves 51, a pair of expansion plates 53 are rotatably installed on the sliding frame 52, the expansion plates 53 are provided with straight slots 56, the top end of the upper clamping piece 24 is fixedly installed with a pair of fixed frames 54, a limiting rod 55 cooperated with the straight slot 56 is rotatably installed in each fixed frame 54, two limiting rods 55 are respectively arranged in the two straight slots 56 and penetrate through the straight slots 56, the top end of the upper clamping piece 24 is provided with a pair of electric telescopic rods 57, the output ends of the two electric telescopic rods 57 are fixedly connected with the sliding frame 52; the bottom end of the expansion plate 53 is provided with a ball 58.

[0059] When the expansion assembly 50 works, the electric telescopic rod 57 is started, and the output end of the electric telescopic rod 57 drives the sliding frame 52 to slide in the sliding groove 51 of the handheld rod 10. In the sliding process, the sliding frame 52 drives the expansion plate 53 connected with the sliding frame 52 to move. The straight slot 56 formed in the expansion plate 53 is matched with the limiting rod 55 rotatably arranged in the fixed frame 54. The limiting rod 55 slides in the straight slot 56, and the limiting rod 55 limits and guides the movement track of the expansion plate 53. With the movement of the sliding frame 52, the expansion plate 53 is gradually unfolded under the action of the limiting rod 55, so that the laryngeal part is expanded. The expansion degree of the expansion plate 53 can be accurately controlled by controlling the expansion and contraction of the electric telescopic rod 57, so as to meet different laryngeal conditions and operation requirements. The electric driving mode is more stable and labor-saving than the manual driving mode, and the accuracy and convenience of the expansion operation are improved.

[0060] The expansion plate 53 is rotatably arranged with the ball 58, and the ball 58 is located at one end of the expansion plate 53 away from the sliding frame 52.

[0061] The ball 58 is rotatably arranged at one end of the expansion plate 53 away from the sliding frame 52. When the expansion plate 53 is unfolded at the laryngeal part and contacted with the laryngeal tissue, the ball 58 can roll and rub with the laryngeal tissue. Compared with the direct sliding contact of the expansion plate 53 with the laryngeal tissue, the friction of the rolling friction is smaller, which can effectively reduce the friction damage of the expansion plate 53 to the laryngeal tissue, reduce the discomfort of the laryngeal tissue in the expansion process, and make the unfolding action of the expansion plate 53 more smooth, so as to avoid the difficulty of the expansion operation or the unnecessary harm to the laryngeal part caused by the too large friction resistance.

[0062] The technical scheme provided by the present application has the following specific working process:

[0063] When the ear-nose-throat laryngeal foreign body taking-out device is used, the operator first holds the handheld rod 10, aims the device at the laryngeal part of the patient, starts the electric telescopic rod 57, and drives the sliding frame 52 to slide in the sliding groove 51 through the output end of the electric telescopic rod 57. The sliding frame 52 drives the expansion plate 53 to unfold. Under the cooperation and guidance of the limiting rod 55 and the straight slot 56, the expansion plate 53 is gradually unfolded, the ball 58 on the expansion plate 53 rolls and contacts the laryngeal tissue, the laryngeal part is expanded, and the laryngeal foreign body is fully exposed, so that the laryngeal foreign body is fully exposed.

[0064] After observing the position of the foreign body, the operator pulls the pull rope 25, the pull rod 22 is driven to slide in the perforation 21, the pull rod 22 drives the lower clamping piece 23 to move towards the upper clamping piece 24, the upper clamping piece 24 cooperates with the lower clamping piece 23, and the foreign body is clamped through the limiting slot 26. At this time, the pull rope 25 is loosened, the clamping plate 32 in the self-locking assembly 30 is clamped with the pull rope 25 under the action of the elastic sheet 34, and self-locking is realized to prevent the foreign body from falling off.

[0065] If the larynx is found to have an infection risk during the clamping process or the larynx is damaged after the foreign matter is taken out, disinfectant needs to be applied, the push rod 43 corresponding to the storage cavity 41 is pushed, the push rod 43 drives the piston plate 42 to slide, and the disinfectant water or liquid medicine in the storage cavity 41 is squeezed, the pressure overcomes the elastic force of the second spring 45, the sealing plate 46 is pushed to slide, the through hole 44 is opened, the liquid medicine flows out and impacts the dispersing blade 48, the dispersing blade 48 rotates around the positioning shaft 47, and the liquid medicine is dispersed and uniformly applied to the larynx.

[0066] After the foreign matter is taken out and the medicine is applied, the pull tube 37 is pushed, the pull tube 37 drives the abutment ring 35 to push the clamping plate 32 to rotate through the connecting rod 36, the clamping groove 33 is separated from the pull rope 25, and the self-locking is released. Under the elastic recovery force of the first spring 27, the pull rod 22 drives the lower clamping piece 23 to reset.
