Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a foreign body forceps for otolaryngology. Background Technology

[0002] Otolaryngological foreign body forceps are precision instruments specifically designed for otolaryngological medical procedures. Their main function is to safely and accurately grasp, remove, or adjust foreign bodies or pathological tissues, such as earwax, small insects, and polyps, in the patient's ear canal, nasal cavity, and throat. These forceps typically have a finely designed tip, allowing them to penetrate narrow and sensitive anatomical structures while minimizing damage to surrounding healthy tissues. They are essential tools for otolaryngologists in performing delicate diagnoses and treatments.

[0003] Existing ENT foreign body forceps have limitations during operation. Due to their design, they make it difficult to clearly observe the internal condition of the ear, nose, and throat simultaneously, requiring auxiliary equipment. Furthermore, due to structural factors, they are prone to falling off after grasping foreign bodies or tissues, which increases surgical risks and operational complexity, affecting diagnostic and treatment efficiency and patient safety. Therefore, we propose an ENT foreign body forceps. Utility Model Content

[0004] The purpose of this invention is to provide a foreign body forceps for otolaryngology to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ENT foreign body forceps, comprising:

[0007] The main body includes a gripping assembly with two rotating clamps for gripping.

[0008] An anti-detachment component is provided inside the main body. The anti-detachment component is equipped with a ratchet and a pawl, which cooperate with the clamping component to prevent detachment.

[0009] A monitoring component is disposed within the main body, and the monitoring component includes a pinhole camera and a display screen for monitoring the clamping status.

[0010] Preferably, the clamping assembly includes:

[0011] A rotating rod is disposed inside the main body, and a rotating shaft is fixedly connected to the outside of the rotating rod. The rotating rod and the main body are rotatably connected through the rotating shaft.

[0012] An outer tube is fixedly connected to one end of the main body, and two connecting plates are fixedly connected to one end of the outer tube;

[0013] Rotary clamps, two of which are rotatably connected between two connecting plates, and worm gears are fixedly connected inside each of the two rotating clamps;

[0014] An inner tube is set inside the outer tube. One end of the inner tube extends into the main body and is fixedly connected to an adapter rod. The adapter rod is rotatably connected to the upper end of a rotating rod. A spring is fitted over the inner tube. One end of the spring is fixedly connected to one end of the inner tube, and the other end is fixedly connected to the inside of the main body.

[0015] A worm gear is fixedly connected to the other end of the inner tube. The worm gear meshes with two worm wheels and is hollow.

[0016] Preferably, the anti-detachment component includes:

[0017] A ratchet, which is fixedly connected to the outer end of the rotating shaft;

[0018] The box body is fixedly connected to one side of the main body, the ratchet is disposed inside the box body, and an arc-shaped groove is provided on the outside of the box body;

[0019] A pawl is rotatably mounted inside the box. A torsion spring is fixedly sleeved on the rotating end of the pawl. One end of the torsion spring is fixedly connected to the outside of the pawl, and the other end is fixedly connected to the inside of the box. A screw is fixedly connected to the extended end of the pawl, and the screw extends out of the arc-shaped groove.

[0020] A nut, which is threaded onto the extended portion of the screw.

[0021] Preferably, the size of the nut is larger than the groove spacing of the arc groove.

[0022] Preferably, the monitoring component includes:

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] 1. By setting up the clamping assembly, gripping the handle and rotating rod will cause the rotating rod to rotate. The rotation of the rotating rod will cause the adapter rod to move, which in turn will cause the inner tube to move inside the outer tube. The movement of the inner tube into the main body will cause the worm to move synchronously. The movement of the worm will cause the two worm wheels to rotate synchronously. The rotation of the two worm wheels will cause the two rotating clamps to rotate relative to each other, thus performing clamping.

[0030] 2. By setting up an anti-detachment component, during the clamping process, the rotating rod rotates and drives the rotating shaft to rotate synchronously. The rotating shaft then drives the ratchet to rotate synchronously. As the ratchet rotates, the pawl engages accordingly, which can limit and hold the rotation of the ratchet. In this way, during the process of driving the two rotating clamps to rotate, due to the presence of the ratchet and pawl, the two rotating clamps will not loosen, thus preventing the clamped object from accidentally falling off.

[0031] 3. By setting up a monitoring component, the clamping end of the device is inserted into the patient's ear, nose, and throat. Then, the pinhole camera is turned on, data is transmitted via a data cable, and the clamping situation is observed on the display screen. Attached Figure Description

[0039] 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. Example 1

[0040] like Figure 1-6 As shown in this embodiment, a foreign body forceps for otolaryngology includes a main body 1. The main body 1 is provided with a gripping component 2, an anti-dislodgement component 3, and a monitoring component 4. The gripping component 2 is used to grip; the anti-dislodgement component 3 cooperates with the gripping component 2 to prevent dislodgement; and the monitoring component 4 is used to monitor the gripping status.

[0041] The clamping assembly 2 includes: a rotating rod 21, an outer tube 22, rotating clamps 23, an inner tube 24, and a worm gear 25. The rotating rod 21 is disposed inside the main body 1, and a rotating shaft 211 is fixedly connected to the outside of the rotating rod 21. The rotating rod 21 and the main body 1 are rotatably connected through the rotating shaft 211. The outer tube 22 is fixedly connected to one end of the main body 1, and two connecting plates 221 are fixedly connected to one end of the outer tube 22. The two rotating clamps 23 are rotatably connected between the two connecting plates 221, and a worm gear 231 is fixedly connected inside each of the two rotating clamps. The inner tube 24 is set inside the outer tube 22. One end of the inner tube 24 extends into the main body 1 and is fixedly connected to the adapter rod 241. The adapter rod 241 is rotatably connected to the upper end of the rotating rod 21. A spring 242 is sleeved on the inner tube 24. One end of the spring 242 is fixedly connected to one end of the inner tube 24, and the other end is fixedly connected to the inside of the main body 1. The worm gear 25 is fixedly connected to the other end of the inner tube 24. The worm gear 25 is meshed with two worm wheels 231. The worm gear 25 is hollow to facilitate the passage of the data cable 43.

[0042] In this embodiment, a handle 5 is fixedly connected to the bottom of the main body 1, which is convenient to hold and to rotate the rotating rod 21.

[0043] In practice, grip handle 5 and rotating rod 21 to rotate the rotating rod 21. The rotation of the rotating rod 21 causes the adapter rod 241 to move, which in turn causes the inner tube 24 to move inside the outer tube 22. The movement of the inner tube 24 into the main body 1 causes the worm gear 25 to move synchronously. The movement of the worm gear 25 causes the two worm wheels 231 to rotate synchronously. The rotation of the two worm wheels 231 causes the two rotating clamps 23 to rotate relative to each other for clamping. Example 2

[0044] Based on Embodiment 1, in order to prevent the object being gripped from accidentally falling off during gripping, an anti-detachment component 3 is provided.

[0045] like Figure 5-6As shown, in this embodiment, the anti-detachment component 3 includes: a ratchet 31, a housing 32, a pawl 33, and a nut 34. The ratchet 31 is fixedly connected to the outer end of the rotating shaft 211; the housing 32 is fixedly connected to one side of the main body 1, the ratchet 31 is disposed inside the housing 32, and an arc-shaped groove 321 is provided on the outside of the housing 32; the pawl 33 is rotatably disposed inside the housing 32, and a torsion spring 331 is fixedly sleeved on the rotating end of the pawl 33. One end of the torsion spring 331 is fixedly connected to the outside of the pawl 33, and the other end is fixedly connected to the inside of the housing 32. A screw 332 is fixedly connected to the extended end of the pawl 33, and the screw 332 extends out of the arc-shaped groove 321; the nut 34 is threadedly connected to the extended section of the screw 332; the size of the nut 34 is larger than the groove spacing of the arc-shaped groove 321, and tightening the nut 34 can fix the screw 332 outside the arc-shaped groove 321.

[0046] In practice, during the clamping process, the rotating rod 21 rotates, causing the rotating shaft 211 to rotate synchronously. The rotating shaft 211 then drives the ratchet 31 to rotate synchronously. As the ratchet 31 rotates, the pawl 33 engages accordingly, which can limit and hold the rotation of the ratchet 31. In this way, during the process of driving the two rotating clamps 23 to rotate, due to the presence of the ratchet 31 and the pawl 33, the two rotating clamps 23 will not loosen, thus preventing the clamped object from accidentally falling off. Example 3

[0047] Based on Embodiment 1 and Embodiment 2, a monitoring component 4 is provided to facilitate observation of the clamping situation.

[0048] like Figure 2-4 As shown, in this embodiment, the monitoring component 4 includes a pinhole camera 41, a display screen 42, and a data cable 43. The pinhole camera 41 is fixedly connected to one end of the worm gear 25; the display screen 42 is fixedly connected to one end of the main body 1; the data cable 43 is electrically connected to the pinhole camera 41 and the display screen 42; the data cable 43 passes through the worm gear 25, the inner tube 24, and the main body 1, and the data cable 43 is bound by a cable tie ring inside the main body 1 to prevent interference with the operation of other mechanisms.

[0049] In practice, the device's gripping end is inserted into the patient's ear, nose, and throat. Then, the pinhole camera 41 is turned on, data is transmitted via the data cable 43, and the gripping situation is observed via the display screen 42.

[0050] Working principle: First, insert the clamping end of the device into the patient's ear, nose, and throat. Then, turn on the pinhole camera 41 and observe through the display screen 42. Grip the handle 5 and the rotating rod 21 tightly, causing the rotating rod 21 to rotate. The rotation of the rotating rod 21 causes the adapter rod 241 to move, which in turn causes the inner tube 24 to move inside the outer tube 22. The movement of the inner tube 24 into the main body 1 causes the worm gear 25 to move synchronously. The movement of the worm gear 25 causes the two worm wheels 231 to rotate synchronously. The rotation of the two worm wheels 231 causes the two rotating clamps 23 to rotate relative to each other for clamping. During the clamping process, the rotation of the rotating rod 21 causes the rotating shaft 211 to rotate synchronously. The rotating shaft 211 in turn causes the ratchet 31 to rotate synchronously. As the ratchet 31 rotates, the ratchet... The pawl 33 engages with the ratchet 31, limiting its rotation. This prevents the two rotating clamps 23 from disengaging during rotation due to the presence of the ratchet 31 and pawl 33, thus preventing accidental drop of the clamped object. When another clamping action is needed, the screw 332 moves downward, causing the pawl 33 to rotate upward, disengaging it from the ratchet 31. Then, the nut 34 is rotated to fix the screw 332, thus fixing the pawl 33. Releasing the lever 21 causes the inner tube 24 to return to its original position via the spring 242, allowing the two rotating clamps 23 to open for the next clamping action, and vice versa.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
