[0030] Foreign bodies in the nasal cavity are a common emergency in otolaryngology, especially in pediatric otolaryngology. Due to children's curiosity, they like to stuff foreign bodies into their nasal cavities. If not handled in time, it may lead to local nasal congestion, infection, bleeding, or even slipping into the trachea and causing suffocation and other serious consequences.
[0031] Foreign bodies in the nasal cavity need to be removed promptly by ENT doctors using instruments. Existing nasal foreign body removal instruments are usually configured with an arc-shaped hook structure. The doctor uses the arc-shaped hook to reach into the nasal cavity and hook out the foreign body step by step. However, if the curvature of this arc-shaped hook structure is not enough, it is not easy to bring out the foreign body. If the curvature is too large, it is not easy to reach in along the foreign body, which makes the doctor more laborious during the operation.
[0032] Reference Figures 1 to 5 The present application provides a nasal foreign body removal device, including a cylinder 100, a slider 200, a straight tube 300, an elastic hook head 400 and a connecting rod device 500.
[0033] The front end of the cylinder 100 is provided with an opening, and a strip groove 110 is provided on the cylinder 100. The strip groove 110 extends along the length direction of the cylinder 100. The slider 200 is assembled inside the cylinder 100. The slider 200 can slide inside the cylinder 100. One end of the straight tube 300 is fixed at the opening of the cylinder 100. The straight tube 300 extends along the length direction of the cylinder 100. The elastic hook head 400 is an arc-shaped structure. The elastic hook head 400 is inserted into the straight tube 300. One end of the elastic hook head 400 is fixed to the slider 200. 00, the elastic hook head 400 can slide in the straight tube 300, and the connecting rod device 500 includes a first rod member 510, a second rod member 520 and an elastic component 530. One end of the first rod member 510 is hinged to one end of the second rod member 520, one end of the elastic component 530 is connected to the first rod member 510, and the other end is connected to the second rod member 520. The other end of the first rod member 510 extends into the strip groove 110 and is hinged to the cylinder body 100, and the other end of the second rod member 520 extends into the strip groove 110 and is hinged to the slider 200.
[0034] The elastic component 530 is a compression spring. When the present application is not in use, the elastic hook head 400 is hidden in the straight tube 300. The initial state of the elastic hook head 400 is a bent state. Under the constraint of the straight tube 300, the elastic hook head 400 is in a straight state in the straight tube 300.
[0035] In the present application, one end of the elastic component 530 is connected to the middle portion of the first rod 510 , and the other end is connected to the middle portion of the second rod 520 .
[0036] In some other embodiments, one end of the elastic component 530 is connected to the middle of the first rod 510 and is hinged, and the other end is connected to the middle of the second rod 520 and is hinged.
[0037] During use, the doctor holds the cylinder 100, first extends the straight tube 300 to a position close to the foreign body in the nasal cavity, and then slowly presses the connecting rod device 500. Under the push of the connecting rod device 500, the slider 200 will drive the elastic hook head 400 to extend from the end of the straight tube 300. When the elastic hook head 400 extends shorter from the end of the straight tube 300, it is basically in a straight line state, so it can easily pass over the foreign body. After the elastic hook head 400 passes over the foreign body, the straight tube 300 can be slowly moved away from the foreign body (to make room for the subsequent extension of the elastic hook head 400), and the connecting rod device 500 is continued to be pressed, so that the elastic hook head 400 continues to extend slowly. When the elastic hook head 400 extends longer, it will rebound to a bent state. After the elastic hook head 400 is extended into place, the cylinder 100 is pulled outward, so that the elastic hook head 400 in the bent state can drive the foreign body out of the nasal cavity. Therefore, in this application, since the elastic hook head 400 can move in the straight tube 300, the elastic hook head 400 can easily pass over the foreign matter in the nasal cavity. At the same time, the elastic hook head 400 will rebound to a bent state after being inserted into place, so it is easy to bring out the foreign matter.
[0038] After use, the doctor releases the pressure on the connecting rod device 500 . At this time, under the rebound force of the elastic component 530 , the connecting rod device 500 drives the elastic hook head 400 to retract into the straight tube 300 .
[0039] In the present application, the slider 200 is a cylindrical structure.
[0040] The slider 200 is provided with a connecting plate 210, which is hinged to the second rod 520. A connecting hole 211 is provided on the connecting plate 210, and the connecting plate 210 and the end of the second rod 520 are hinged via a rotating shaft.
[0041] In order to ensure that the slider 200 slides stably in the cylinder 100 and does not rotate relative to the cylinder 100, in some embodiments, slide grooves 220 are provided on both sides of the slider 200, and the slide grooves 220 extend along the length direction of the slider 200. A slide rail is provided inside the cylinder 100, and the slide rail extends along the length direction of the cylinder 100, and the slide grooves 220 cooperate with the slide rails.
[0042] The front end of the cylinder 100 is provided with a tapered end, and the rear end of the cylinder 100 is an open structure. One end of the slide rail extends to the rear end of the cylinder 100, and the other end extends to the tapered end. The two slide rails are distributed on both sides of the connecting rod device 500. The front end of the slider 200 is also provided with a tapered end, which can match the tapered end of the front end of the cylinder 100. One end of the chute 220 extends to the tapered end of the front end of the slider 200, and the other end extends to the rear end surface of the slider 200. When the connecting rod device 500 pushes the slider 200 to slide, the slider 200 can only move forward and backward along the slide rail. The cooperation between the slide rail and the chute 220 limits the rotation of the slider 200 relative to the cylinder 100.
[0043] In some embodiments, a ball head structure 410 is provided at one end of the elastic hook head 400 away from the slider 200. This prevents the end of the elastic hook head 400 from causing damage to the inner wall of the nasal cavity.
[0044] In some embodiments, a connecting tube 500 is fixed on the slider 200, and the connecting tube 500 is concentrically arranged with the cylinder 100. The rear end of the connecting tube 500 extends from the rear end of the cylinder 100, and the elastic hook head 400 is connected to the connecting tube 500. An air outlet 420 is provided at the end of the elastic hook head 400 away from the slider 200. The air outlet 420 is located on the rear side of the ball head structure 410. The outside of the air outlet 420 surrounds the elastic airbag 430. An air pipe 600 is provided inside the elastic hook head 400 and inside the connecting tube 500. One end of the air pipe 600 is connected to the air outlet 420, and the other end extends to the rear end of the connecting tube 500. When the foreign body in the nasal cavity is small and difficult to remove, after the end of the elastic hook head 400 is extended to the rear of the foreign body, the elastic airbag 430 is also located behind the foreign body. Gas is introduced into the elastic airbag 430 through the trachea 600, causing the elastic airbag 430 to swell. At this time, when the elastic hook head 400 is pulled out, the foreign body can be brought out through the elastic airbag 430.
[0045] In the embodiment shown in the present application, a circle of grooves 440 are provided on the elastic hook head 400 near the rear of the ball head structure 410, the air outlet 420 is provided in the groove 440, and the elastic airbag 430 is a silicone film wrapped around the groove 440. When the air outlet 420 releases air, the elastic airbag 430 made of silicone material will bulge.
[0046] The connecting tube 500 is fixed to the middle of the slider 200, and the front end of the connecting tube 500 extends from the front end of the slider 200. The elastic hook 400 is connected to the front end of the connecting tube 500. The elastic hook 400 is hollow, and the air pipe 600 is arranged inside the elastic hook 400 and the connecting tube 500.
[0047] An end plate is further provided at the rear end of the cylinder 100 , and an avoidance hole is provided on the end plate, and the rear end of the connecting pipe 500 extends out from the avoidance hole.
[0048] In some embodiments, a balloon 700 is installed at the rear end of the connecting tube 500, and the balloon 700 is communicated with the trachea 600. When the elastic airbag 430 needs to be inflated, the doctor can directly press the balloon 700 to inflate the elastic airbag 430.
[0049] In some embodiments, two air outlet holes 420 are provided, and the two air outlet holes 420 are arranged opposite each other. This allows for more uniform air discharge. The embodiments of the present application are described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present application.
