Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a rapid nasal foreign body removal device. Background Technology

[0002] Nasal foreign bodies are a common clinical condition, especially in children. They are often made of plastic or metal and are usually smooth, round (like beans, glass beads, or peanuts) or irregular in shape. Nasal foreign bodies can cause purulent discharge with a foul odor. If they accidentally fall into the trachea, they can cause suffocation. Therefore, they need to be removed promptly, usually using a removal hook.

[0003] For example, the utility model disclosed in authorization announcement number CN217066545U includes a rod body. A rod 1 is fixedly installed on one side of the rod body. A hook head is provided at the end of the rod 1 away from the rod body. A sliding rod 2 is installed on the other side of the rod body. An abutment part is provided at the end of the rod 2 away from the rod body. The abutment part can slide up and down with the rod 2 to approach or move away from the hook head. This method involves moving the hook head to the rear of the foreign object stuck in the nasal cavity using a handheld rod. For example, when the patient's head is facing the doctor, the area above the foreign object in the nasal cavity is the rear of the object. Then, the push rod is used to bring the abutment part against the foreign object. The hook head and the abutment part work together to clamp and fix the foreign object, confining it between the hook head and the abutment part. This ensures that the foreign object will not scratch the nasal cavity mucosa when it is removed, making it easy for the doctor to remove the foreign object quickly and safely. However, before removing the nasal foreign object, it cannot open the nasal cavity near the foreign object. When the hook head enters, it is easy to abrade the patient's nasal mucosa and cause injury. At the same time, it cannot quickly adjust the angle and direction of the hook head, affecting the efficiency of the hook head's entry. The overall operation is inconvenient. Therefore, we propose a rapid nasal foreign body removal device. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-4This utility model provides a technical solution: a nasal foreign body quick removal device, including a grip sleeve 3, and two sets of opening mechanisms 1 for expanding the nasal cavity are provided on one side of the grip sleeve 3;

[0030] A drive mechanism is provided inside the grip sleeve 3. The drive mechanism includes a bidirectional rack 31, which meshes with the transmission gear 15. The bidirectional rack 31 is movably set inside the grip sleeve 3 through a translation component. By moving the bidirectional rack 31, it can simultaneously drive two sets of transmission gears 15 to rotate synchronously in opposite directions.

[0031] The spreading mechanism 1 includes a transmission gear 15, which is mounted on a rotating shaft 14. The rotating shaft 14 is rotatably mounted inside the grip sleeve 3. A spreading arm 12 is also mounted on one side of the rotating shaft 14. The rotating shaft 14 is driven to rotate by the transmission gear 15, which can synchronously spread or retract the spreading arm 12.

[0032] The translation component includes an adjusting screw 33, which is rotatably mounted in a threaded hole. A toggle handwheel 32 is also mounted on the adjusting screw 33. By rotating the toggle handwheel 32, the rotation direction of the adjusting screw 33 can be controlled. The threaded hole is located on one side of the grip sleeve 3. One end of the adjusting screw 33 is rotatably mounted in a bearing sleeve 34, which ensures the rotation and movement of the adjusting screw 33. The bearing sleeve 34 is located on one side surface of the bidirectional rack 31. By rotating the adjusting screw 33, the bidirectional rack 31 can be driven to move laterally.

[0033] First, the location of the foreign object in the nasal cavity is determined using lighting equipment. Then, the two sets of spreading arms 12 are moved to the vicinity of the foreign object in the nasal cavity. At this time, the spreading arms 12 are in the retracted state. Then, the swivel handwheel 32 is rotated, which drives the adjusting screw 33 to rotate. The adjusting screw 33 rotates in the bearing sleeve 34, which drives the bidirectional rack 31 to move through the bearing sleeve 34. The bidirectional rack 31 moves simultaneously, which drives the two sets of transmission gears 15 to rotate in opposite directions. The transmission gears 15 drive the rotating shaft 14 to rotate, which drives the two sets of spreading arms 12 to rotate in opposite directions. By unfolding the spreading arms 12, the nasal cavity in the abdominal cavity of the foreign object is assisted in opening, increasing the gap between the nasal cavity and the foreign object, making it easier for the hook head 222 to move to the rear of the foreign object.

[0034] Furthermore, a limiting rod 35 is provided on the outer surface of the bearing sleeve 34, and a slider is provided at one end of the limiting rod 35. The slider is slidably disposed in the slide groove, which is disposed on the inner wall of the grip sleeve 3. When the adjusting screw 33 drives the bearing sleeve 34 to move, the bearing sleeve 34 drives the limiting rod 35 to move, and the limiting rod 35 drives the slider to move in the slide groove, thereby guiding and limiting the movement of the bearing sleeve 34.

[0035] Furthermore, the extension arm 12 is movably disposed within the adjustment port 13, which is located on the other side surface of the grip sleeve 3. During the unfolding process, the extension arm 12 moves within the adjustment port 13, facilitating the expansion movement of the extension arm 12.

[0036] Furthermore, an arc-shaped support arm 11 is provided at one end of the opening arm 12. The arc-shaped support arm 11 and the opening arm 12 are integrally formed. When the opening arm 12 is opened, it drives the arc-shaped support arm 11 to open, so that the arc-shaped opening arm 12 fits against the inner wall of the nasal cavity, which improves the comfort of the patient when using the nasal cavity.

[0037] Example 2

[0038] Please see Figure 2 , Figure 3 , Figure 5 as well as Figure 6 The grip sleeve 3 has a retrieval mechanism 2 in the middle. The retrieval mechanism 2 includes a support rod 23, which is movably mounted in a positioning sleeve 26. The positioning sleeve 26 is mounted in a central hole 25, which is mounted on the grip sleeve 3. An extension rod 221 is provided on one side of the support rod 23, which can adjust the movement depth and angle of the hook head 222. One end of the extension rod 221 is provided with a hook head 222 with gradually decreasing thickness, which can facilitate moving the hook head 222 to the back of the foreign object without damaging the patient's nasal mucosa.

[0039] Multiple springs 27 are provided on the outer surface of the positioning sleeve 26. One end of the spring 27 is connected to the center hole 25. The positioning sleeve 26 is deflected by the center rod 22. The positioning sleeve 26 causes the spring 27 to deform, which can adjust the deflection angle of the positioning sleeve 26, thereby adjusting the deflection angle of the hook head 222.

[0040] A center rod 22 is also provided at the other end of the bearing rod 23. One end of the center rod 22 passes through the adjustment cavity 24 and extends out of the other side of the grip sleeve 3. The adjustment cavity 24 is located in the middle of the bidirectional rack 31, the adjustment screw 33 and the plum blossom handwheel 32. A grip rod 21 is also provided on one side of the center rod 22 to facilitate the adjustment of the angle and movement depth of the bearing rod 23.

[0041] After expanding the nasal cavity, first push the gripping rod 21. The gripping rod 21 moves the central rod 22 within the adjustment cavity 24. The movement of the central rod 22 moves the bearing rod 23 within the positioning sleeve 26. The bearing rod 23 moves the extension rod 221, which in turn moves the hook head 222 to the foreign object position. Then rotate the gripping rod 21, which, through the central rod 22, drives the bearing rod 23 to rotate within the positioning sleeve 26. The support rod 23 then drives the hook head 222 to rotate, and rotates the hook head 222 to a position with a large gap between the foreign object and the object. At the same time, the gripping rod 21 swings. The gripping rod 21 drives the positioning sleeve 26 to deflect within the central hole 25 through the central rod 22 and the support rod 23, thereby adjusting the deflection angle of the hook head 222. Then, the gripping rod 21 is pushed, and the hook head 222 is moved through the gap to the rear of the foreign object. The gripping rod 21 is pulled back, and the hook head 222 removes the foreign object from the nasal cavity.

[0042] Furthermore, the end of the hook head 222 is provided with an arc-shaped guide portion 223, which can avoid damage to the nasal mucosa.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
