Description

Technical Field

[0001] The invention belongs to the field of otolaryngology instruments, and more specifically, belongs to an ear canal foreign body remover. Background Art

[0002] Foreign bodies in the ear canal refer to the injurious diseases caused by foreign bodies accidentally entering the external auditory canal. Foreign bodies are divided into three categories: non-biological, such as stones, small toys, etc.; plant, such as beans, seeds, etc.; animal, such as flying insects, cockroaches, etc.; clinical manifestations are foreign body sensation in the ear. If the foreign body exists for a long time, it may be complicated with infection or be wrapped by earwax to form earwax embolism.

[0003] Because the ear canal mucosa is thin and has a lot of secretions, when the foreign body in the ear canal is small and has a certain weight, it is easily wrapped by the secretions of the ear canal mucosa and has strong adhesion. It cannot be removed by softening the earwax and flushing. The nerves in the ear canal are very sensitive, and it is very painful when removing the foreign body.

[0004] When otolaryngologists remove small, heavy, and irregularly sized foreign bodies that are attached to the ear canal mucosa, they generally use foreign body forceps to clamp the foreign bodies in the ear canal. However, the foreign body forceps in the prior art require too high professional skills from doctors when operating them. When the patient is irritable or uncooperative, the tip of the foreign body forceps is prone to damage the external ear canal mucosa, causing pain to the patient, or the foreign body is easily pushed deeper into the ear canal when clamping the foreign body, and the clamped foreign body is prone to slipping. Therefore, a new technology is needed to improve this solution. Summary of the invention

[0023] In this embodiment, the other end of the support handle 4 is connected with the lower end side of the movable clamp 5, the movable clamp 5 is arranged longitudinally, and a limiting groove 5a is provided in the middle of the movable clamp 5. The limiting groove 5a is a laterally recessed contour, and the upper end side of the movable clamp 5 is elastically connected with the upper end of the limiting groove 5a, so that the whole formed by the clamp handle 6, the adjusting part 7, the connecting handle 8, and the traction block 10 can be inclined toward the overall direction formed by the support part 1, the support part extension part 3, and the support handle 4.

[0024] In this embodiment, the other end of the upper part of the movable clamp 5 is connected to one end of the clamp handle 6, and the other end of the clamp handle 6 is connected to the end of the adjusting member 7. The middle part of the adjusting member 7 is in a longitudinal convex shape. The adjusting member 7 is a deformable adjusting member 7, and the other end of the adjusting member 7 is connected to one end of the connecting handle 8.

[0025] In this embodiment, the other end of the connecting handle 8 is connected to the end of the traction extension 9. A traction block 10 is provided at the end of the traction extension 9. The longitudinal side of the traction block 10 is connected to the oblique side of the traction block 10 to form a tip 10a of the traction block 10. The longitudinal side of the traction block 10 is an arc surface, and the tip 10a is configured so that foreign matter in the ear canal adhering to the ear canal mucosa can be dropped by the tip 10a.

[0026] In this embodiment, the clamping handle 6, the connecting handle 8, the traction extension 9, and the traction block 10 are arranged horizontally, and the whole formed by the support part 1, the support extension 3, and the support handle 4 and the whole formed by the clamping handle 6, the adjusting part 7, the connecting handle 8, the traction extension 9, and the traction block 10 are arranged vertically, and the other end of the support extension 3 and the end of the traction extension 9 are in the same longitudinal plane, the length of the support extension 3 is A, and the length of the traction extension 9 is B, and A<B;

[0027] In this embodiment, the edge of the tip 10a of the traction block 10, the arc surface of the lower surface of the groove 2, and the arc surface of the lower surface of the support 1 are in contact with the contour of the external auditory canal. When the upper surface of the movable clamp 5 is under force, since the upper end side of the movable clamp 5 is elastically connected with the upper end of the limiting groove 5a, the clamp handle 6, the connecting handle 8, the traction extension 9, and the traction block 10 are formed as a whole in an inclined state. The tip 10a of the traction block 10 and the lower surface of the support 1 are in the same horizontal plane, wherein the edge of the longitudinal arc surface of the traction block 10 is consistent with the contour of the external auditory canal, so that the ear canal foreign matter adhered to the ear canal mucosa can be limited by the inclined surface of the tip 10a of the traction block 10 while avoiding damage to the ear canal mucosa.

[0028] In this embodiment, the distance between the two ends of the adjusting member 7 in the initial state is X, and the distance between the two ends of the adjusting member 7 after adjustment is Y, X>Y, so that the connecting handle 8, the traction extension member 9, and the traction block 10 form a whole lateral movement. Since the edge of the lower surface of the groove 2 forms an oblique angle with the outer surface of the support portion 1, the foreign matter in the ear canal limited on the inclined surface forming the tip 10a of the traction block 10 can be pushed to enter the groove 2 with less resistance. The edge of the tip 10a of the traction block 10 fits with the inner surface of the groove 2.

The upper end side of the movable clamp 5 is elastically connected with the upper end of the limiting groove 5a, so that the whole formed by the clamp handle 6, the adjusting member 7, the connecting handle 8, and the traction block 10 is tilted. Since the tip 10a of the traction block 10 is consistent with the contour of the external auditory canal, the ear canal foreign bodies adhering to the ear canal mucosa can be surrounded by the inclined surface of the tip 10a of the traction block 10, while avoiding damage to the ear canal mucosa; by making the distance Y between the two ends of the adjusting member 7 after adjustment less than the distance X between the two ends of the adjusting member 7 in the initial state, and the edge of the lower surface of the groove 2 By forming an oblique angle with the outer surface of the support portion 1, the foreign body in the ear canal limited on the inclined surface forming the tip 10a can be pushed into the groove 2 with less resistance. The inclined surface forming the tip 10a of the traction block 10, the side surface of the groove 2, and the bottom surface of the groove 2 form a semi-closed shape. The inclined surface forming the tip 10a of the traction block 10 can press the foreign body in the ear canal tightly into the groove 2, effectively solving the problem that when an ENT doctor clamps small and heavy foreign bodies of different shapes and sizes adhering to the ear canal mucosa, the external ear canal mucosa is damaged, causing pain to the patient, or the foreign body is pushed deep into the ear canal when clamping the foreign body, and the clamped foreign body is easy to slip.

[0030] In this embodiment, the support extension 3 and the support handle 4, the traction extension 9 and the connecting handle 8 are respectively connected through the bends 11, and the two adjacent bends 11 are arranged in parallel. The bends 11 are arranged so that the operating part of the ENT doctor and the external auditory canal mucosa where foreign objects are adhered are not on the same central axis, which facilitates operation.

[0031] In this embodiment, the outer surfaces of the support handle 4 and the connecting handle 8 are provided with anti-skid grooves 8a, which are serrated, and the lateral concave contour of the limiting groove 5a is adapted to the contour of the thumb tip.

[0032] The working principle of this embodiment is as follows:

[0033] S1: The operator's thumb presses against the outer surface of the limit groove 5a, the index finger and the middle finger press against the upper surface of the joint between the adjustment member 7 and the connecting handle 8; the ring finger and the little finger press against the lower surface of the support handle 4;

[0034] S2: Pull the ear canal to make the external auditory canal straighten, and push the lower surface of the support part 1 against the ear canal mucosa, so that the front end of the device (including the support part 1, the groove 2, the support part extension 3, the traction extension 9, and the traction block 10) extends into the external auditory canal where the ear canal foreign body is attached, and reaches the target position where the ear canal foreign body exists, so that the ear canal foreign body is located at the horizontal middle of the tip 10a of the traction block 10 and the edge of the lower surface of the support part 1;

[0035] S3: The index finger and the middle finger press against the connecting handle 8 and apply downward force. Since the clamp handle 6, the adjusting member 7, the connecting handle 8, the traction extension member 9 and the traction block 10 form a horizontally arranged whole, and the upper end side of the movable clamp 5 is elastically connected with the upper end of the limiting groove 5a, the whole formed by the clamp handle 6, the adjusting member 7, the connecting handle 8 and the traction block 10 can be tilted toward the whole direction formed by the support part 1, the support extension member 3 and the support handle 4, so that the tip 10a of the traction block 10 falls on one end of the target position. Since the edge of the tip 10a is an arc that fits the contour of the ear canal, the ear canal foreign matter adhering to the ear canal mucosa can be surrounded by the inclined surface of the tip 10a to limit the ear canal mucosa, while avoiding damage to the ear canal mucosa;

[0036] S4: The index finger and the middle finger press against the adjusting member 7 and apply a force in the direction of the limiting groove 5a, so that the distance Y between the two ends of the adjusting member 7 is greater than the distance X between the two ends of the adjusting member 7 in the initial state, so that the whole formed by the connecting handle 8, the traction extension member 9 and the traction block 10 moves laterally toward the adjusting member 7. Since the edge of the lower surface of the groove 2 forms an oblique angle with the outer surface of the support portion 1, the foreign matter in the ear canal limited on the inclined surface forming the tip 10a can be pushed into the groove 2 with less resistance, and the inclined surface forming the tip 10a of the traction block 10 can press the foreign matter in the ear canal tightly into the groove 2.
