Description

Technical Field

[0001] The invention relates to a foreign body remover, in particular to a foreign body remover for complex esophageal fold walls. Background Art

[0002] The esophagus is a muscle-made passage that connects the throat to the stomach. The esophageal wall includes a submucosa, which is composed of thick and loose connective tissue and contains esophageal glands that secrete mucus into the esophageal cavity through ducts. The mucosa and submucosa form seven to ten longitudinal folds, and the cross section is star-shaped. Foreign bodies in the esophagus are more common in the elderly and children. The elderly are mostly due to tooth loss or the use of dentures, poor chewing function, poor oral sensation, and a loose esophageal opening, which makes it easy to swallow foreign bodies by mistake, such as fish bones, chicken bones, and jujube pits; children are mostly caused by swallowing toys in their mouths, such as buttons, coins, pebbles, and chewing gum. In addition, esophageal stenosis or esophageal lesions are also common causes of esophageal foreign bodies. When the esophagus is diseased, wrinkles are likely to appear on the esophageal wall. At this time, when swallowing food, small foreign bodies are easily stuck in the folded wall. If foreign bodies in the esophagus are stuck for too long, it will lead to more complications, and the foreign bodies need to be removed in time. For foreign bodies stuck in the folds of the esophagus, the foreign body forceps currently used are of a caliper-type structure with poor freedom of movement and low control accuracy. Not only is it difficult to find the exact position to quickly remove the foreign body, but for some patients who have chicken bones or duck bones stuck in the esophagus vertically through the esophageal wall, directly pulling the bones out can easily damage the esophagus and increase the patient's pain.

A storage bag 45 is provided inside the auxiliary sleeve 4. A storage space 46 is formed between the storage bag 45 and the inner wall of the auxiliary sleeve 4. A suction tube 23 which penetrates into the interior of the forceps rod 2 is provided in the storage space 46.

[0026] An arc-shaped airbag 47 is provided inside the clamp rod 2 near the clamp head. A top block abutting against the inner wall of the clamp rod 2 is provided at the closed end of the arc-shaped airbag 47 , and a second inflation tube is provided at the open end of the arc-shaped airbag 47 .

[0027] The storage bag 45 includes a support grid 451, and a pleated isolation rubber film 452 is provided on one side of the support grid 451 facing the suction port 44. A one-way membrane valve 441 is provided at the suction port 44, and the membrane valve 441 is composed of two arc-shaped membrane petals abutting against each other. Through the provision of the membrane valve 441, only foreign matter can be sucked into the suction port 44, and foreign matter is prevented from escaping from the suction port 44; the support grid 451 stabilizes the structure of the storage bag 45, and prevents it from closing under negative pressure and affecting the storage space; the pleated isolation rubber film 452 can clamp and accommodate small foreign matter under negative pressure, thereby further preventing foreign matter from escaping.

[0028] The umbrella of the umbrella-shaped airbag 42 is composed of a plurality of arc-shaped pieces connected to each other. In the contracted state, the arc-shaped pieces are folded to each other. When inflated, the arc-shaped pieces are rotated and unfolded. The umbrella-shaped airbag 42 is used, and its structure is easier to extend into the esophageal folds. The rotational unfolding method reduces the damage to the inner wall of the esophagus, and the supporting effect on the esophageal folds is more stable, avoiding slippage.

[0029] The outside of the clamp rod 2 is also provided with a sleeve 24, on which a slider 25 is provided which is slidably connected to the sleeve 24, on which an elastic support plate 26 is symmetrically provided, and on which a silicone layer is wrapped on the outside of the elastic support plate 26; the sleeve 24 is also provided with a plurality of bayonet holes 27, and on the slider 25 is provided a buckle 28 which is engaged with the bayonet holes 27. The elastic support plate 26 is used to support the patient's oral cavity so that the patient's oral cavity is opened, which is convenient for medical staff to better handle; the elastic support plate 26 slides on the sleeve 24 through the slider 25, so as to adjust the position of the elastic support plate 26 and better adapt to different patients.

[0030] The opening end of the auxiliary sleeve 4 is provided with a mounting sleeve 5, which is rotatably connected to the auxiliary sleeve 4. The surface of the mounting sleeve 5 is provided with a sliding sleeve 51, and the interior of the sliding sleeve 51 is provided with an internal spline. The fixed clamp head 31 extends into the sliding sleeve 51, and the claw portion of the fixed clamp head 31 is larger than the sliding inner diameter of the sliding sleeve 51. The surface of the fixed clamp head 31 is provided with a plurality of convex strips 33 embedded in the internal spline. This structure realizes the rotation and movement of the fixed clamp head 31 relative to the auxiliary sleeve 4, so that the fixed clamp head 31 can accurately align with the stretched foreign body and quickly grab it.

[0031] The handle includes a fixed handle 11 and a movable handle 12 which are hinged to each other. A pair of arc-shaped elastic sheets 16 are provided between the fixed handle 11 and the movable handle 12. One end of one arc-shaped elastic sheet 16 is connected to the fixed handle 11, and one end of the other arc-shaped elastic sheet 16 is connected to the movable handle 12. The other ends of the two arc-shaped elastic sheets 16 abut against each other.

[0032] A movable seat 13 is provided in the connection end of the handle, one end of the movable seat 13 is connected to the movable handle 12, the other end of the movable seat 13 is rotatably connected to one end of the pull rod 21, and the other end of the pull rod 21 is connected to the movable clamp head 32; the connection end of the handle is rotatably connected to the clamp rod 2 through a connection part 14, and a rotating wheel 15 is provided on the connection part 14. By rotating the movable handle 12, the movable clamp head 32 can be driven to rotate by utilizing the linkage effect of the movable seat 13 and the pull rod 21 to achieve the clamping of foreign objects; by rotating the rotating wheel 15, the clamp rod 2 is driven to rotate, thereby driving the clamp head to rotate, and the clamping of foreign objects at different positions is achieved, and it is easy to control.

[0033] The lower end of the movable handle 12 is provided with a mounting seat 17, an adjustment bar 171 is hinged on the mounting seat 17, a rack 172 is provided on the adjustment bar 171, and a convex tooth 18 meshing with the rack 172 is provided below the fixed handle 11. The convex tooth 18 is engaged with the rack 172 on the adjustment bar 171 to fix the distance between the fixed handle 11 and the movable handle 12, thereby improving the firmness of clamping the foreign body and preventing the foreign body from falling due to the looseness of the handle during the removal of the foreign body from the esophagus.

[0034] Working principle: the patient's oral cavity is propped open by the elastic support plate 26, the auxiliary sleeve 4 is inserted into the esophagus, the location of the foreign body is observed, the foreign body is placed between two adjacent umbrella-shaped airbags 42, the tips of the adjacent umbrella-shaped airbags 42 are inserted into the folded walls on both sides of the foreign body, and the first inflation tube 22 inflates the umbrella-shaped airbags 42, so that the umbrella-shaped airbags 42 slowly expand, prop up the folded walls, and expand the esophagus; at this time, the two umbrella-shaped airbags 42 are convex and concave in the middle, and the foreign body is just stuck between the two umbrella-shaped airbags 42; if the volume of the foreign body is large, the rotating wheel 15 is turned, and the fixed clamp head 31 is driven to rotate by the rotation of the clamp rod 2, so that The fixed clamp head 31 is aligned with the foreign object, and then the clamp head is moved toward the side of the foreign object until the fixed clamp head 31 contacts the foreign object, and the foreign object can be clamped and removed with the movable clamp head 32. After the foreign object is clamped, the convex teeth 18 can be engaged with the rack 172 to improve the clamping degree; if the volume of the foreign object is small, air is sucked through the suction pipe 23, and the storage space 46 forms a negative pressure space, so that the foreign object is separated from the inside of the esophagus and sucked into the storage space 46 from the suction port 44. In addition, the folded structure of the storage bag 45 is tightened under negative pressure, which can better wrap small foreign objects and prevent small foreign objects from falling out, and the absorption is strong;

[0035] The arc-shaped airbag 47 can also be inflated to bend the forceps rod 2, which is made of a flexible and bendable material, so that the angles of the forceps head and the auxiliary sleeve 4 can be changed, making it more suitable for the complex environment in the esophagus.
