At least the outer surface 203 is formed to have a predetermined elasticity so that the second body 20 can be made of a metal material and / or a plastic material, It is possible to maintain a state in which it is well inserted in the ear canal and can not be shaken.
- the second body 10 may include a second-first end 201 and a second-second end 202 facing each other. As described above, when the second body 20 is inserted into the ear canal, The second-first end 201 has a smaller cross-section than the second-second end 202. [ When the second tip 2 is inserted into the ear canal, the second-first end 201 may be provided such that its cross-section is smaller than the inside of the ear canal so as to be positioned adjacent to the ear.
- a second handle 24 may be further provided on the outside of the second-second end 202 of the second body 20.
- the second handle 24 may be formed along the outer edge of the second-second end 202.
- the length S of the second body 20 may be defined as the length between the second-first end 201 and the second-second end 202, When inserted, the second-second end 202 can be set to a length that can be exposed to the outside of the ear.
- the second body 20 may be formed to have the same thickness from the second-first end 201 to the second-second end 202. However, the present invention is not limited thereto, May be formed so as to give a suitable thickness variation to be combined.
- the second-1 opening 21 may be located at the second-first end 201 and the second-second opening 22 may be located at the second-second end 202. As shown in FIG. 15, the second-1 opening 21 may be formed to be smaller than the second-second opening 22.
- the second communication passage 23 is located between the second opening 21 and the second opening 22 and the second communication passage 23 communicates with the inner surface 204 of the second body 20, Can be defined by the shape.
- the inner surface 204 may be formed to have a smooth surface for facilitating attachment and detachment of the first tip of the above-described embodiments.
- the first tip 1 of the above-described embodiments is inserted into the second communication path 23 of the second tip 2, and the injection needle passes through the first tip 1 Lt; / RTI > That is, the medical staff can insert the second tip 2 into the patient's ear first to observe the ear condition of the patient through the wider second communication path 23 more clearly.
- the position and / or condition of the eardrum can be confirmed through the headlight worn by the medical staff, so that it can be easily performed without using a microscope for eardrum injection as in the prior art.
- the first tip 1 is inserted into the second communication path 23, and the needle is allowed to pass through the first communication passage 13, thereby precisely piercing the eardrum.
- the medical staff can observe the ear condition more accurately and can perform accurate ejaculation scanning successively.
- the length S of the second tip 2 as described above may be equal to or longer than the length 1 of the first tip 1 described above. That is, in the coupled state, the first-second end 102 of the first tip 1 and the second-second end 202 of the second tip 2 may be structured to meet with each other, And the second end 102 is drawn inward from the second-second end 202.
- first tip 1 and the second tip 2 may have a structure in which the first-first end 101 and the second-first end 201 coincide with each other.
- the present invention is not limited to this.
- the first-first end 101 may protrude to the outside of the second-1 opening 21.
- the second tip 2 extends and protrudes toward the eardrum, the effect of extending the first tip 1 closer to the eardrum can be obtained.
- the structure may be such that the first-first end 101 does not protrude outside the second-1 opening 21 but is located inside the second-first end 201 have.
- the second tip 2 can be scanned as it is while being positioned adjacent to the eardrum, it is possible to prevent the patient from feeling a sense of heterogeneity as the first tip approaches the eardrum.
- 19 is a cross-sectional view showing another embodiment in which the first and second tips 1 and 2 are combined.
- the 1-1 opening 11 formed in the first tip 1 is formed to have a size slightly larger than the diameter of the injection needle so as to be large enough to allow the injection needle to pass therethrough,
- the 1-2 opening 12 can be formed to have a very large size.
- the first body 10 may have the same thickness from the 1-1 opening 11 to the 1-2 opening 12. Since the first tip 1 having such a structure has an angle change only within the range of the forming angle of the inner surface of the first body 10 forming the first communication path, the angle of the inner surface of the first body 10 It is possible to pierce the eardrum without shaking the needle.
- the first tip 1 as described above is joined to the second tip 2 as shown in Fig. 19, the first-first end 101 and the second-first end 201 are fixed
- the needle 1 having passed through the 1-1 opening 11 passes through the 2-1 opening 21 so that the angle range B at which the needle can move is narrowed,
- the practitioner may be able to push the eardrum only by injecting it in any way. Therefore, a more accurate ejaculation injection can be achieved.
- the first body 10 of the first tip 1 can be formed thinner than the first body 10 of the first embodiment described above, the first tip 1 can be mass-produced at a lower cost .
- the microscope can be operated only in the adjacent eardrum chair.
- the procedure is performed once, it is necessary to lie in the chair for more than 40 minutes. During the period, the chair can not be used for other treatments or treatments, and the patient has to discomfort for a long time in the uncomfortable chair.
- the needle may shake and the eardrum may be torn finely.
- the patient may move his / her head due to fear and pain during the procedure, and the motion of the patient during the procedure may cause tearing of the eardrum.
- the micropore of the tympanic membrane formed by the injection needle becomes larger, which may lead to perforation of the tympanic membrane causing the patient's hearing loss.
- the present invention can prevent the shaking of the injection needle due to the shaking of the medical staff or the movement of the patient, thereby reducing the possibility of perforation of the tympanic membrane after the procedure.
- It can be used as an eardrum tip for injecting into the eardrum.
