Embodiment 1

[0042] combined with Figure 1~2 , the helmet-type fixed artificial middle ear hearing compensation performance preoperative evaluation tester of the present invention, by comparing and evaluating the hearing compensation performance of different artificial middle ears, it is beneficial for patients to choose a more suitable artificial middle ear, and the hearing compensation performance of the artificial middle ear before operation The evaluation tester includes a helmet-type fixing device 100 , a coupling rod 200 , an actuator clamping device 300 , a two-dimensional slider adjusting device 400 , a Z-axis (ear canal direction) and an angle adjusting device 500 .

[0043] Such as image 3 , the helmet type fixing device 100 comprises a cross belt 110, a sliding buckle mechanism 120 and a headband 130, the cross belt 110 and the headband 130 are flexible materials, there are buttonholes at regular intervals on the cross belt 110 and the headband 130, and the sliding buckle mech...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that: Figure 3-5 and attached Figure 11 , attached Figure 12 , the present invention includes a helmet-type fixing device 100, a coupling rod 200, an actuator fixing device 300, a three-dimensional slider mechanism 700 and a gear mechanism 800;

[0053] The three-dimensional slider mechanism 700 includes a Z-axis slider mechanism 710, a Y-axis slider mechanism 720, an X-axis slider mechanism 730, and a slider fixing jaw 740; the slider fixing jaw 740 clamps the headband of the helmet-type fixing device 100 130, and then use bolts to fix the three-dimensional slider mechanism 700 and the helmet-type fixing device 100 through the threaded hole 750. Compared with the two-dimensional slider mechanism 400, the three-dimensional slider mechanism 700 can adjust the positioning of the coupling rod 200 to the position of the ear canal opening, It is also possible to adjust the displacement of the coupling rod 200 on...

Embodiment 3

[0058] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that: Figure 4-10 , the present invention includes a glasses-type fixing device 600, a coupling rod 200 and an actuator fixing device 300, an ear canal direction and angle adjusting device 500, and a two-dimensional slider mechanism 400;

[0059] The glasses-type fixing device 600 includes a spectacle frame 610, a spectacle frame 620 and a chute device 630, the spectacle frame 610 and the spectacle frame 620 support the whole device, the chute device 630 includes a guide rail 631 and a chute 632, according to the patient's head size, by adjusting the chute 632 to adjust the distance between the mirror frames 610, and then fix the whole device;

[0060] The two-dimensional slider mechanism 400 clamps the frame 610 of the glasses-type fixing device 600 through the slider fixing jaw 430 , and then fixes the two-dimensional slider mechanism 400 and the glasses-type fixing device 600 through the thr...

Abstract

The invention relates to a preoperative evaluation tester for hearing compensation performance of an artificial middle ear. The preoperative evaluation tester comprises a fixing and supporting device,a position and angle adjusting device, a coupling rod and an actuator clamping device, the fixing and supporting device is a flexible element, the position and angle adjusting device is fixed to thefixing and supporting device through bolts, the coupling rod is fixed to the position and angle adjusting device through bolts, the actuator clamping device is connected with the coupling rod througha thread pair, an included angle of 45 degrees is formed between the actuator clamping device and the coupling rod, and a layer of exciting film is arranged at the tail end of the actuator clamping device and attached to the output end of an actuator when the actuator is installed, so that the actuator directly couples with the eardrum. The position and angle adjusting device of the preoperative evaluation tester can adjust the pose of the output end of the actuator installed on the tester, accordingly, the output end of the actuator and the eardrum are better coupled, the effect of the actuator is made closer to the hearing compensation effect during implantation, and the hearing compensation effect after the artificial middle ear actuator is implanted into the body of a patient can be evaluated more accurately.

Description

technical field [0001] The invention relates to the technical field of hearing aids, in particular to an artificial middle ear hearing compensation performance preoperative evaluation tester. Background technique [0002] Hearing impairment is one of the most common diseases in the country. According to the mechanism of damage, hearing loss is mainly divided into sensorineural hearing loss and conductive hearing loss. In recent years, with the continuous improvement of the level of clinical surgery, the research on the implantation technology of various ossicular prostheses has made it possible for most patients with conductive hearing loss to reconstruct their hearing through surgery; Wearing traditional hearing aids improves hearing, but wearing traditional hearing aids has many disadvantages. For sensorineural hearing loss, it is generally better to wear traditional hearing aids to improve hearing, but wearing traditional hearing aids has many disadvantages, such as: po...
