Embodiment 1

[0032] Such as figure 2 As shown, a round window vibration-excited artificial middle ear actuator whose initial pressure can be monitored includes a support device 40 , a distance adjustment device 100 , a housing 80 and a telescopic device 200 . see Figure 4 , the supporting device is a combined structure including a base 41 , a spherical locking nut 44 and a spherical bracket 42 , and the front end of the supporting device 40 is connected to the distance adjusting device 100 . The supporting device 40 is fixed on the bone wall 8 opposite to the round window membrane 7 through implantation, and provides a fixed support for the entire actuator 10 . The rear end of the base 41 is fixed above the bone wall 8 opposite to the round window membrane 7 through bone nails. The support method of the actuator 10 in the ear of the present invention adopts a mechanical structure fixing method, and the rear end of the actuator 10 is fixed by the bone nails. It is fixed above the bone w...

Embodiment 2

[0041] Such as Figure 8 As shown, the support device 50 of this embodiment is set as the protruding part above the support plate 111 , and directly fixes the actuator 10 above the bone wall 8 opposite to the round window membrane 7 through bone screws. This embodiment can provide more stable support for the actuator 10, and is suitable for patients whose implantation environment near the round window is ideal. Other technical solutions are the same as in Embodiment 1.

Embodiment 3

[0043] Such as Figure 9 with Figure 10 As shown, the supporting device 60 of the present embodiment is set as a pawl bracket, and the pawl support is a square thin plate, and one end is a flat end connected to the support plate 111; the other end is provided with a pawl, and the pawl end is against the The bone wall 8 opposite to the round window membrane 7 , the detent structure can adapt to the complex shape of the bone wall 8 and provide stable support for the actuator 10 . In this embodiment, the bone nail fixation method is replaced by a support fixation method, which effectively reduces the operational difficulty of the surgical implantation process, and the support method does not need to be fixed by bone nails, which avoids the problem of secondary trauma. Other technical solutions are the same as in Embodiment 1.

Abstract

A round window excitation type manual middle lug actuator with the initial pressure capable of being monitored comprises a supporting device, a distance adjusting device, a shell and a telescopic device, the front end of the supporting device is connected with the distance adjusting device, the shell and the front end of the distance adjusting device form a moving pair, the whole telescopic deviceis located in the shell, and the front end of the telescopic device directly acts on a round window film; The supporting device is fixed on a bone wall opposite to the round window membrane through an implantation operation; Telescopic device comprises an expansion device, a load indicator, a spring and a coupling rod, the spring is arranged in the center of the rear end of the expansion piece and abuts against the rear wall of the inner side of the shell, the load indicator is arranged at the top of the rear end of the expansion piece, the expansion piece moves in the axial direction of theshell, the coupling rod is arranged at the front end of the expansion piece and directly acts on the round window film, and the maximum diameter of the front end of the coupling rod is 1 mm. The support rigidity of the actuator is improved, the loss of the output quantity of the actuator is reduced, the hearing compensation effect of the actuator is improved, and the initial pressure between the actuator and a round window film can be monitored.

Description

technical field [0001] The invention relates to a round window vibration-exciting artificial middle ear actuator whose initial pressure can be monitored, and belongs to the technical field of hearing aids. Background technique [0002] Hearing impairment is one of the common diseases affecting people's daily life. According to the mechanism of hearing impairment, hearing impairment can be divided into conductive hearing impairment and sensorineural hearing impairment. With the continuous deepening of otology research and the rapid development of ear microsurgery, most patients with conductive hearing loss can improve their hearing through surgery, but for sensorineural hearing loss, traditional hearing aids are generally used to improve hearing. . However, traditional hearing aids have problems such as low output gain (unable to compensate for a high degree of hearing loss), acoustic feedback, and ear canal blockage. Many patients are unwilling to wear them, and those who a...
