Detailed Description
In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.
A pull ring applied to a guide wire of a catheter pulled out through a nasal cavity in an oral cavity is shown in figure 1 and comprises a handle part 10, a fixed part 20 and a pull ring part 30, wherein the handle part 10 and the pull ring part 30 are both fixed on the fixed part 20, and the pull ring part 30 comprises an elastic closed ring; referring to fig. 2 and 3, the fixing portion 20 is a wedge-shaped body with a thin tail end, a thick head end and smooth sides, and an elastic tooth-protecting layer 21 is wrapped on the outer surface of the fixing portion 20.
The utility model discloses a be applied to oral cavity nasal cavity and pull ring of pulling away pipe seal wire, pull ring portion tractive stretches into the phlegm sucking pipe wherein, and handle portion is used for gripping, and the fixed part is used for fixed pull ring portion and handheld portion. The pull ring part 30 may be a closed ring surrounded by guide wires. The tooth protecting layer can be food-grade silica gel.
The utility model discloses a be applied to oral cavity intranasal cavity and pull ring of pulling out pipe seal wire, mainly used is through the scope retrograde nose bile duct implantation drainage art and esophagus support implantation art in, helps nose bile duct or fish tape to pull out by oral cavity to nasal cavity. Taking the nose bile duct as an example, the nose bile duct is implanted into the bile duct from the mouth in a retrograde manner through an endoscope, the tail part of the nose bile duct leaks outside the body, the nose bile duct outside the body can be drawn out from the nasal cavity through the oral cavity, the comfort degree of a patient is improved, complications are reduced, and the working pressure of medical staff is relieved. When in use, the pull ring part 30 of the pull ring enters the oral cavity and is lightly pasted on the posterior pharyngeal portion; then the sputum suction tube is inserted from the nasal cavity, enters the esophagus, then enters the pull ring part 30 of the pull ring downwards, and the pull ring is pulled lightly to pull out the sputum suction tube through the oral cavity; then the nasal bile duct is sleeved into the sputum suction tube, the sputum suction tube is pulled from the nasal part, when the sputum suction tube is pulled out of the nasal cavity, the nasal bile duct is pulled out together, the nasal bile duct is pulled out of the nasal cavity through a required path, and then the nasal bile duct is fixed to finish the operation, so that the operation can be smoothly finished. Compared with the traditional method, the passive blind fetching is changed into the active fetching, and meanwhile, the fetching improves the accurate rate of the traction of the nose bile duct, avoids repeated operation, enables the operation to be successful at one time, shortens the operation time and reduces the X-ray irradiation time of a patient.
The fixing part 20 is a wedge-shaped body with a thin tail end, a thick head end and smooth two sides, and an elastic tooth protection layer 21 wraps the outer surface of the fixing part 20. When the part of the body is put into the oral cavity, the body is lower than the front and back parts of the body, the patient feels comfortable, the mouth opening is not too large, the body cannot slide and hurt the teeth even if the body is bitten by the teeth, and the corners and the buccal sides of the mouth cannot be abraded due to smooth two sides. The pull ring part 30 is parallel to the horizontal plane of the fixing part 20, so that the area of the pull ring part 30 can be kept as large as possible, and the sputum suction tube inserted from the nasal cavity can be covered.
In an embodiment of the present invention, as shown in fig. 4, a groove 22 is disposed at the tail end of the fixing portion 20, and two threaded holes 23 are disposed in the groove 22; still include elastic cone anchor clamps, combine fig. 5 to show, elastic cone anchor clamps include connecting portion 41, slip ring 42 and toper clamping part 43, be equipped with breach 44 on the toper clamping part 43, the outside of connecting portion 41 is equipped with the screw thread, with screw hole 23 cooperation. This is a fixed connection that is removable. When the pull ring part 30 is installed, one end of the pull ring part is inserted into the conical clamping part 43, the sliding ring 42 is pulled to be clamped, and then the connecting part 41 is screwed into the threaded hole 23 to be fixed. The other end is operated the same. In an embodiment of the present invention, a line connecting two of the threaded holes 23 is parallel to a horizontal plane of the fixing portion 20; the tapered holding portion 43 does not go beyond the recess 22, and the tapered holding portion 43 is prevented from protruding out of the recess 21 and coming into contact with the oral cavity.
In an embodiment of the present invention, as shown in fig. 6, the handle portion 10 includes a first handheld portion 11 located at one end away from the pull ring portion 30 and a second handheld portion 12 located at the middle of the pull ring portion 30, the first handheld portion 11 is provided with a circular hole 13, and the second handheld portion 12 is provided with an annular groove 14. The second handheld part 12 is used for holding the palm upwards, is suitable for short-distance micro control and is convenient to insert into the oral cavity; the first handheld part 11 is used for holding the palm of the hand downwards, and the forefinger can be stretched into the round hole 13, so that the first handheld part is suitable for being pulled for a long distance, and the sputum suction tube can be conveniently pulled outwards.
To sum up, the preferred embodiment of the present invention is only, the protection scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the patent scope and the content of the specification of the present invention are all within the scope covered by the present invention.
