Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an improved foreign body removal forceps for otolaryngology. Background Art

[0002] Foreign body remover is a medical device, commonly used in otolaryngology to remove foreign bodies in the patient's respiratory or digestive tract. In clinical treatment, many patients seek medical treatment because of foreign bodies entering the respiratory or digestive tract, such as fish bones or fruit cores. In the above cases, foreign body remover can be used to remove the foreign body.

[0003] Traditional foreign body removal forceps usually consist of a forceps head, a forceps body, a handle and a grip ring. When using foreign body removal forceps, otolaryngologists need to insert the forceps body and the forceps head into the patient's narrow ear, nose and throat, and clamp the foreign body to remove it. During this process, the doctor needs to maintain a high degree of concentration and keep his hands stable to avoid deviation, which may cause the clamped foreign body to damage the ear, nose and throat. However, the grip ring of traditional foreign body removal forceps is relatively smooth, which is not conducive to keeping the hand stable when clamping. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an improved foreign body removal forceps for ENT to solve the technical problem that the grip ring of the existing foreign body removal forceps for ENT is relatively smooth, which is not conducive to keeping the hand stable in the clamping state.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an improved foreign body removal forceps for otolaryngology, comprising a forceps body, a forceps head, a first handle, a second handle and a grip ring, the inner side of the grip ring is provided with an anti-slip pad and an adjustment mechanism, the adjustment mechanism comprises a screw and an arc block, a movable plate is provided at one end of the screw, a rotating head is provided at the end of the screw away from the movable plate, and a gasket is provided on one side of the movable plate.

[0006] By adopting the above technical solution, by setting up anti-slip pads and adjustment mechanisms, the doctor's hand stability and gripping feeling are enhanced during use by increasing friction and abutting limit respectively, effectively preventing surgical errors caused by hand slippage.

[0007] Furthermore, the anti-skid pad is made of anti-skid silicone material, the anti-skid pad is fixedly connected to the grip ring, and a bump is arranged on the anti-skid pad.

[0008] By adopting the above technical solution, the anti-slip pad made of non-slip silicone material provides excellent friction, and combined with the design of the bumps, it further enhances the adhesion between the hand and the grip ring and reduces slippage.

[0009] Furthermore, there are a plurality of protrusions, which are distributed in a circle, and the protrusions and the anti-slip pad are made of the same material.

[0010] By adopting the above technical solution, the design of multiple bumps can provide multi-point support according to the actual use of the doctor's hands and enhance the stability of holding.

[0011] Furthermore, the rotating head is fixedly connected to the screw, the screw is threadedly connected to the grip ring, the screw is rotationally connected to the movable plate, and the movable plate is fixedly connected to the gasket.

[0012] By adopting the above technical solution, rotating the rotating head can drive the screw fixedly connected to it to rotate. With the assistance of the threaded connection between the screw and the grip ring, the screw pushes the moving plate and the gasket fixed on the moving plate to make fine adjustments to their positions.

[0013] Furthermore, the movable plate is an arc-shaped plate structure, and the curvature of the movable plate is adapted to the curvature of the inner side of the grip ring.

[0014] By adopting the above technical solution, the movable plate with an arc-shaped plate structure is adapted to the curvature of the inner side of the grip ring, so that the movable plate can fit perfectly with the inner side of the grip ring when it is fully retracted.

[0015] Furthermore, the gasket is fixed on the inner side of the movable plate, and the gasket is made of memory foam.

[0016] By adopting the above technical solution, the fixed position of the gasket ensures the stability and comfort of the doctor's fingers during the operation.

[0017] Furthermore, a sliding rod is arranged on the outer side of the movable plate, and a sleeve rod is arranged on the outer side of the grip ring.

[0018] By adopting the above technical solution, the arrangement of the sliding rod and the sleeve rod can help the movable plate to remain stable when it contacts the hand.

[0019] Furthermore, the sleeve rod is fixedly connected to the grip ring, the slide rod is fixedly connected to the movable plate, and the slide rod is slidably connected to the sleeve rod.

[0020] By adopting the above technical solution, the fixed connection between the sleeve rod and the grip ring provides a solid supporting foundation for the slide rod, thereby ensuring the stability of the adjustment mechanism.

[0021] Furthermore, two groups of the sleeve rods and the slide rods are provided, and the two groups of the sleeve rods and the slide rods are symmetrically distributed along the screw rod.

[0022] By adopting the above technical solution, the symmetrically distributed sleeve rod and slide rod provide a balanced supporting force, avoiding hand instability caused by asymmetrical design.

[0023] Furthermore, two pliers heads are provided, and teeth are provided on the facing surfaces of the two pliers heads.

[0024] By adopting the above technical solution, when a doctor uses foreign body removal forceps to clamp a foreign body, the two forceps heads can be used to achieve clamping.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model provides anti-skid pads, bumps, screws, movable plates and gaskets. The anti-skid pads and bumps can prevent the hand from shifting by increasing the friction when the hand clamps the foreign object, thereby helping the hand to remain stable. At the same time, because the finger thickness of doctors using foreign body forceps is not consistent, the screws can be used to fine-tune the positions of the movable plate and the gasket. Regardless of the size of the doctor's finger, it can ensure that the gasket made of memory foam is always in contact with the back of the finger, further helping the finger to remain stable.

[0027] 2. The utility model can assist the movable plate to maintain stability when it contacts the hand by setting the sleeve rod and the slide rod, and avoid the movable plate from rotating randomly due to the force applied to the hand during use due to the rotation connection with the screw rod. At the same time, the slide rod is pulled out of the sleeve rod, or the sleeve rod is retracted to adapt to the fine-tuning process of the movable plate, avoiding the setting of the sleeve rod and the slide rod from hindering the adjustment of the movable plate.

The tooth design of the forceps heads 2 enhances the gripping force when clamping the foreign body and improves the success rate of the operation.

[0047] The implementation principle of the utility model is as follows: first, when in use, the doctor inserts the finger of one hand into the grip ring 5, the center of the finger contacts the anti-slip pad 6 and one side of the protrusion 7, and uses the other hand to rotate the rotating head 82, driving the screw 81 fixedly connected thereto to rotate, pushing the movable plate 85 and the gasket 86 to move, until the gasket 86 made of memory foam material stably abuts against the corresponding position of the back of the finger, ensuring that the finger will not deviate at will and there is no obvious discomfort on the back of the finger; in this process, as the movable plate 85 moves, the sliding rod 84 slides out of the sleeve rod 83 and extends, preventing the movable plate 85 from rotating due to the force when the hand applies force; afterwards, the doctor uses the assistance of an endoscope or other instruments to move the forceps body 1 and the forceps The head 2 extends into the part of the patient where the foreign body is stuck, clamps the foreign body, and removes it. During the removal process, the doctor's finger tips are limited by the friction of the anti-slip pad 6 and the protrusion 7, and the backs of the fingers are fixed by the movable plate 85 and the gasket 86 to prevent them from slipping out of the grip ring 5 during the hand exertion, which helps to keep the hand stable to a certain extent; after the foreign body is clamped out, the rotating head 82 can be rotated in the reverse direction to drive the screw rod 81 to rotate in the reverse direction. At this time, the sliding rod 84 slides back to the sleeve rod 83, driving the movable plate 85 and the gasket 86 to move outward, releasing the abutment restriction on the doctor's fingers, making it convenient for the doctor to pull his fingers out of the grip ring 5. When the movable plate 85 moves to the vicinity of the arc block 87, due to the curvature design of the arc block 87, the movable plate 85 can pass smoothly here.
