Abstract
Description
Technical Field
[0001] The utility model relates to a nasal foreign body remover, belonging to the field of medical equipment. Background Art
[0002] Foreign bodies in the nasal cavity usually occur when some small objects accidentally enter the nasal cavity, causing difficulty breathing or other discomfort symptoms. For example, children may put small objects into their nostrils. Children may put small objects such as melon seeds, buttons, and paper scraps into their nostrils when playing. For example, when eating, food may be inhaled into the nasal cavity. These foreign bodies are difficult to expel on their own and need to be removed by medical means.
[0003] At present, when it is necessary to remove foreign bodies from the nasal cavity, the removal instruments used are usually made on-site by doctors using paper clips or dental wires, and the accuracy is poor. There are also some nasal foreign body removers on the market, but there are still some inconvenient operating problems, which need to be further optimized. For example, the structure of some nasal foreign body removers is similar to that of an ear pick. When removing foreign bodies, it is necessary to continuously rub against the inner wall of the nasal cavity to "scrape" the foreign bodies out, which causes great damage to the nasal mucosa. For another example, the structure of some nasal foreign body removers is similar to that of dental forceps. They need to be opened at a certain angle to enter the nostrils and clamp the foreign bodies out of the nostrils. When encountering children or patients with small nostrils, the forceps-type structure is difficult to enter the nostrils. Utility Model Content

[0025] Reference Figures 1 to 3 The embodiment of the present application provides a nasal foreign body remover, including a fixing hook 11 and a movable column 2 with a front end (the end aligned with the nasal cavity when in use is defined as "front" in the present application, the same below) aligned with the fixing hook 11, a cylindrical shell 3 is sleeved on the outer periphery of the movable column 2, a fixing strip 1 extending from the front end of the cylindrical shell 3 and parallel to the movable column 2, the fixing hook 11 is connected to the front end of the fixing strip 1, the cylindrical shell 3 is fixedly connected to a palm handle 33, the middle part of the palm handle 33 is connected to a hinge shaft 5, the hinge shaft 5 is connected to the middle part of a finger handle 4, and one end of the finger handle 4 is connected to a transmission mechanism for controlling the movement of the movable column 2 along the cylindrical shell 3.
[0026] It should be noted that Figures 1 to 3 The size ratios between the components are not necessarily the same as in reality, in order to clearly show the smaller components. For example, compared with the drawings, in reality the fixing bar 1 and the movable column 2 are thinner, and the fixing hook 11 is smaller.
[0027] The palm handle 33 and the cylinder shell 3 always remain relatively still, and is actually a fixed handle. It is called a palm handle because it contacts the palm when in use; the finger handle 4 rotates around the hinge shaft 5, and is actually a movable handle. It is called a finger handle because it contacts the finger when in use. Before use, the front end of the movable column 2 is separated from the fixed hook 11.
[0028] When in use, first extend the fixing strip 1 into the nasal cavity so that the fixing hook 11 is at the deep side of the foreign body. After the fixing hook 11 hooks the foreign body, pinch the palm handle 33 and the finger handle 4, and the transmission mechanism moves the movable column 2 toward the fixing hook 11 until the front end of the movable column 2 reaches the shallow side of the foreign body (the side closer to the nostril in the nasal cavity), clamping the foreign body between the front end of the movable column 2 and the fixing hook 11, thereby smoothly clamping the foreign body out of the nasal cavity.
[0029] The nasal foreign body remover can clamp the front end of the movable column 2 with the fixed hook 11 by pinching the palm handle 33 and the finger handle 4, which is beneficial for the operator to hold the nasal foreign body remover firmly and control the clamping action with one hand. When entering the nasal cavity, the fixed bar 1 is advanced and the movable column 2 is advanced backward, and the fixed bar 1 is parallel to the movable column 2, which is beneficial for entering the smaller nostrils and clamping the foreign body. The foreign body is removed by clamping rather than scraping or sweeping, which causes less damage to the nasal mucosa.
[0030] In order to improve the clamping effect of foreign objects, the front end of the movable column 2 is a hemispherical pit 21, so that the front end of the movable column 2 becomes a tray that can receive foreign objects, which is helpful to prevent foreign objects from slipping off. The direction of the depression can be depression toward the rear end of the movable column 2.
[0031] The fixing hook 11 is a circular ring or an elliptical ring, which is convenient for removing foreign matter and is not easy to scratch the inner wall of the nasal cavity when entering the nasal cavity. Figure 2 , the fixing hook 11 forms an angle of 100°~120° with the fixing bar 1, and correspondingly, the front end of the movable column 2 is also inclined at the same angle to cooperate with the fixing hook 11. The fixing hook 11 forms a smaller obtuse angle with the fixing bar 1, which is conducive to placing the fixing hook on the deep side of the foreign body, and it is less likely to scratch the inner wall of the nasal cavity when clamping the foreign body and removing it. Specifically, when the fixing hook 11 is a circular ring, the plane where the circular ring is located forms an angle of 100°~120° with the fixing bar 1; when the fixing hook 11 is an elliptical ring, the long axis of the elliptical ring forms an angle of 100°~120° with the fixing bar 1.
[0032] For easy operation, the rear section of the movable column 2 extends out of the cylinder shell 3 and is provided with an ear plate 22. A spring 221 is connected between the rear end of the cylinder shell 3 and the ear plate 22, and the action direction of the spring 221 is parallel to the movable column 2. When the palm handle 33 and the finger handle 4 are pinched, the movable column 2 moves forward, and the ear plate 22 moves toward the rear end of the cylinder shell 3, so that the spring 221 is in a compressed state. After releasing the palm handle 33 and the finger handle 4, the elastic force of the spring 221 can automatically reset the movable column 2, and driven by the transmission mechanism, the finger handle 4 is also automatically reset.
[0033] Correspondingly, the barrel shell 3 is provided with a second screw hole and a second adjusting knob 32 matched with the second screw hole, and the inner end of the second adjusting knob 32 abuts against the movable column 2 in the barrel shell 3. Tightening the second adjusting knob 32 can fix the movable column 2 to prevent the movable column 2 from automatically resetting at an inappropriate time. In this way, the use operation becomes: when the front end of the movable column 2 and the fixing hook 11 are in a separated state, the fixing strip 1 is extended into the nasal cavity, so that the fixing hook 11 is at the deep side of the foreign body, the palm handle 33 and the finger handle 4 are pinched by hand until the foreign body is clamped between the front end of the movable column 2 and the fixing hook 11, the second adjusting knob 32 is tightened to clamp the foreign body out of the nasal cavity, and finally the second adjusting knob 32 is loosened, and the elastic force of the spring 221 is used to reset the movable column 2 and the finger handle 4.
[0034] Preferably, a slide groove for the fixing strip 1 to slide is provided in the cylinder shell 3, so that the length of the fixing strip 1 extending out of the cylinder shell 3 is adjustable, and a first screw hole and a first adjusting knob 31 cooperating with the first screw hole are provided on the cylinder shell 3, and the inner end of the first adjusting knob 31 abuts against the fixing strip 1 in the slide groove. Similar to the second adjusting knob 32, tightening the first adjusting knob 31 can lock the position of the fixing strip 1, and the length of the fixing strip 1 extending out of the cylinder shell 3 can be adjusted only after the first adjusting knob 31 is loosened.
[0035] The palm handle 33 and the finger handle 4 are hinged in an "X" shape, the upper end of the palm handle 33 is fixedly connected to the bottom of the barrel shell 3, and the upper end of the finger handle 4 is connected to the transmission mechanism. Below the hinge shaft 5, the finger handle 4 is in front of the palm handle 33. When pinching the handle, the fingers move while the palm does not move, which is conducive to holding the nasal foreign body remover steadily with one hand. Preferably, a protrusion 331 is provided on the palm handle 33, and the protrusion 331 is higher than the hinge shaft 5 and behind the finger handle 4. When holding the nasal foreign body remover, the protrusion 331 is against the base of the hand, which is more conducive to the operator holding the nasal foreign body remover steadily with one hand.
