Description

Technical Field

[0001] The present invention specifically relates to a nasal foreign body removal device. Background Art

[0002] Foreign bodies in the nasal cavity refer to substances that enter the nasal cavity from outside and remain in the nasal cavity. They can be divided into the following three types: (1) non-biological, such as candy wrappers, plastic, plastic toys, buttons, necklace beads, glass beads, stones and soil; (2) plant, such as beans, peanuts and fruit pits; (3) animal, such as insects, roundworms, maggots and leeches. The main causes include the following: (1) Children are curious and may accidentally put toy parts or food into their nostrils, which enter the nasal cavity. They dare not tell their parents and forget about it until infection and bleeding occur, which is then noticed; (2) Food and roundworms enter the nasal cavity through the posterior nostril during vomiting or sneezing. Occasionally, live fish and shrimp jump into the nasopharynx and enter the nasal cavity through the posterior nostril; (3) Foreign bodies enter the nasal cavity due to trauma, combat injuries or work-related injuries, often accompanied by foreign bodies in the spiracles and eye sockets; (4) During nasal surgery, the surgeon accidentally fills the nasal cavity with gauze or oil gauze and forgets to remove it, which is called iatrogenic foreign body; (5) Insects can lay eggs in the nostrils of weak and comatose patients, which become foreign bodies in the nose such as maggots. Tropical residents who drink unclean river water or swim in unclean river water may have foreign bodies such as leeches enter the nasal cavity.

[0003] Nasal foreign bodies are common in clinical practice, and are more common in children. Foreign bodies are often round structures with smooth surfaces, which are difficult to remove. Ordinary medical treatment often uses a combination of spreaders and tweezers to remove them. However, there are two types of tweezers currently used in clinical practice. One type has a straight clamping part, which is convenient for insertion, but it is easy to cause loose clamping and slipping during clamping; the other type of tweezers has a clamping end that is tilted and bent inward. Although this type of tweezers is convenient for clamping, because both clamping ends are bent outward, it is easy to push the foreign body outward during the process of extending deep into the nasal cavity, and even cause the foreign body to fall into the pharynx or trachea, causing serious consequences. Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a nasal foreign body removal device, which is convenient for placing the clamping end deep in the nasal cavity and for removing round foreign bodies.

DETAILED DESCRIPTION

[0028] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0029] See also Figures 1 to 3 The present invention provides a nasal foreign body removal device, including an operating rod 100, a clamping portion 200 and a first rotating driving member 300.

[0030] Specifically, there are two operating rods 100, and the two operating rods 100 are hinged to each other to form a tweezer shape. One end of the operating rod 100 is an insertion end, and the other end is an operating end, and the insertion end can be inserted into the human nasal cavity. The insertion ends of the two operating rods 100 are hinged to a clamping portion 200 extending along the insertion end through a first hinge; and the first hinge is close to the inside. The first rotating drive member 300 is arranged at the hinge between the operating rod 100 and the clamping portion 200, and can drive the clamping portion 200 to rotate inward around the first hinge.

[0031] When in use, hold the operating rod 100, insert the clamping part 200 and the insertion end into the nasal cavity, so that the clamping part 200 is inserted between the foreign body and the inner wall of the nasal cavity, and then continue to push forward. When the clamping part 200 passes over the foreign body, the first rotating driving member 300 can drive the clamping part 200 to rotate inward around the first hinge to form a barb shape, and then pull the operating rod 100 backward, and the foreign body can be easily taken out through the clamping part 200.

[0032] When using the above-mentioned nasal foreign body removal device, since the operating rod 100 and the clamping part 200 are located in the same straight line during insertion, the device can be easily inserted. When removing the foreign body, since the two clamping parts 200 can bend inward to form a barb shape, they can be hooked on the surface of the foreign body to form a surrounding structure for the foreign body, thereby conveniently removing the foreign body.

[0033] In this embodiment, the first rotary drive member 300 includes a first airbag 310 and a first inflating device 320. The end of the operating rod 100 close to the clamping portion 200 is provided with a first mounting groove recessed inwardly, the first airbag 310 is arranged in the first mounting groove, the first inflating device 320 is connected with a first air pipe, and the first air pipe is connected to the first airbag 310. When the first airbag 310 is inflated, the first airbag 310 can extend out of the first mounting groove to lift the end of the clamping portion 200 outwardly, thereby driving the clamping portion 200 to rotate inwardly.

[0034] In the initial state, the clamping part 200 and the operating rod 100 are located on the same straight line. When the clamping part 200 is located on a foreign object, the first airbag 310 is inflated through the first inflation device 320, and the first airbag 310 expands outward, pushing the end of the clamping part 200 outward, thereby driving the clamping part 200 to rotate inward.

[0035] As a preferred embodiment, the device further includes a limiting structure 400. Specifically, the limiting structure 400 includes a limiting rod 410 and a linear motion driving member 420. A first plug hole is provided at the end of the operating rod 100 facing the clamping portion 200, and the limiting rod 410 can be slidably inserted into the first plug hole. A second plug hole coaxially arranged with the first plug hole is provided at the end surface of the clamping portion 200 facing the operating rod 100, and the other end of the limiting rod 410 can be slidably inserted into the second plug hole. The linear motion driving member 420 is arranged in the first plug hole and connected to the limiting rod 410. The linear motion driving member 420 can drive the limiting rod 410 to slide in the first insertion and second plug holes so that the limiting rod 410 is inserted into or out of the second plug hole.

[0036] In the initial state, the limit rod 410 is inserted into the second socket, which can prevent any clamping block 220 from swinging inward. When the clamping block 220 needs to rotate, the limit rod 410 needs to be driven inward and disengaged from the second socket by the linear motion drive member 420, so that the first airbag 310 can drive the clamping block 220 to rotate inward.

[0037] Specifically, the linear motion driving member 420 includes an elastic support member 421, a pull rope 422 and a wire winder 423. The limit rod 410 is arranged in the first plug hole through the elastic support member 421, and the wire winder 423 is arranged at the operating end of the operating rod 100. The pull rope 422 is wound on the wire winder 423, and the end of the pull rope 422 can slide through the operating rod 100 and connect with the end of the limit rod 410. Pulling the pull rope 422 can drive the limit rod 410 to retract and disengage from the second plug hole.

[0038] In the normal state and during the insertion process, the limit rod 410 is inserted into the second plug hole. When the clamping part 200 needs to be driven to rotate inward, the pull rope 422 is retracted by the winder 423, and the pull rope 422 pulls the limit rod 410 to retract and disengage from the second plug hole.

[0039] It should be noted that the wire winder 423 is a wire winding wheel or a reel with a self-locking function in the prior art.

[0040] In this embodiment, the clamping portion 200 includes a second rotating drive member 210 and a plurality of clamping blocks 220 hinged in sequence by a second hinge, and the second hinge is arranged close to the inner side. The second rotating drive member 210 is connected to all the clamping blocks 220 and can drive all the clamping blocks 220 to rotate inward at the same time, and two adjacent clamping blocks 220 abut against each other.

[0041] When in use, the clamping part 200 and the operating rod 100 are kept in a straight line, and the clamping part 200 is placed between the foreign body and the inner wall of the nasal cavity through the operating rod 100. When the clamping part 200 is located at the foreign body, the second rotating driving member 210 drives all the clamping blocks 220 to rotate inward, so that each clamping block 220 deflects toward the foreign body until it is wrapped around the surface of the foreign body, and then the operating rod 100 is pulled back, and the clamping block 220 will hook on the surface of the foreign body to take the foreign body out. In this way, by wrapping the clamping block 220 on the surface of the foreign body, the clamping force of the clamping part 200 can be increased, the clamping stability can be improved, and the chance of the clamping part 200 slipping can be reduced.

[0042] In this embodiment, the second rotary drive member 210 includes a second airbag 211 and a second inflating device 212. A second airbag 211 is provided between adjacent clamping blocks 220, and a second mounting groove is provided on the end surface between each two adjacent clamping blocks 220. A second airbag 211 is provided in each second mounting groove, and a second air pipe is connected to the second inflating device 212, and the second air pipe is connected to all the second airbags 211. When the second airbag 211 is inflated, the second airbag 211 can extend out of the second mounting groove to lift the end of the corresponding clamping block 220 outward, thereby driving the clamping part 200 to rotate inward.

[0043] When in use, the second airbag 211 only needs to be inflated or deflated through the second inflation device 212 to achieve bending or straightening of the clamping portion 200 .

[0044] It should be noted that, in specific implementation, the second inflatable device 212 can be the same device as the first inflatable device 320, and can be connected to the corresponding air pipe through a three-way connection. At the same time, the air pipe connected to the second airbag 211 should also be provided with a corresponding pressure gauge or switch valve.

[0045] As another preferred embodiment, a third mounting groove can be provided on the inner end surface of each clamping block 220, and an auxiliary grip 500 is provided in the third mounting groove. When the clamping block 220 rotates inward, the auxiliary grip 500 can extend from the third mounting groove. The auxiliary grip 500 is used to hook onto the surface of the foreign object.

[0046] Specifically, the auxiliary grab 500 includes a grab rod 510 and a stop block 520. One end of the grab rod 510 is hinged in a third mounting groove. The length of the grab rod 510 is greater than the thickness of the third mounting groove. The stop block 520 is set and fixed in the third mounting groove and is closely set to the hinge of the grab rod 510. It is located on the side away from the operating rod 100 relative to the grab rod 510.

[0047] When the clamping block 220 tilts toward the foreign object, under the action of gravity, the grab bar 510 automatically rotates downward and extends out of the third installation slot, and the grab bar 510 can be freely inserted into the corresponding pit, thereby further improving the gripping force.

[0048] As a more preferred embodiment, the grab bar 510 can be configured as an elastic bar, which is located in pits adapted to different depths.

[0049] How to use the above nasal foreign body removal device:

[0050] When in use, while ensuring that the limit rod is inserted into the second plug hole, hold the operating rod 100, insert the clamping part 200 and the insertion end into the nasal cavity, so that the clamping part 200 is inserted between the foreign body and the inner wall of the nasal cavity, and then continue to push forward. When the clamping part 200 passes over the foreign body, the pull rope 422 is retracted through the winder 423, and the pull rope 422 pulls the limit rod 410 back and disengages from the second plug hole. Subsequently, the first airbag 310 and the second airbag 211 are inflated through the first inflation device 320 and the second inflation device 212, driving the clamping part 200 to hold the surface of the foreign body. At this time, the grabbing rod 510 extends from the third mounting groove and grabs the pit on the surface of the foreign body. Finally, pull the operating rod 100 backward, and the foreign body can be easily taken out through the clamping part 200.

[0051] When using the above-mentioned nasal foreign body removal device, since the operating rod 100 and the clamping part 200 are located in the same straight line when inserted, the device can be easily inserted. When removing the device, since the two clamping parts 200 can bend inward to form a barb shape, they can be hooked on the surface of the foreign body to form a surrounding structure for the foreign body, thereby providing a stable wrapping force for the foreign body and conveniently removing the foreign body.
