Embodiment 1

[0044] see Figure 4 , a fixed bracket for a round window vibration type artificial middle ear actuator, including a fixed shell 402, an elastic bracket 401, a positioning device 403 and a supporting back seat 404. refer to Figure 5 and Figure 6 , the fixed housing 402 is equipped with an actuator 107 inside, and a plurality of elastic brackets 401 are arranged symmetrically on both sides of the outside. The elastic support 401 includes a front elastic support 505 and a rear elastic support 506. The front elastic support 505 can adaptively deform in the bone groove 601 drilled beside the round window membrane 109 according to the spatial structure, so that it can fit in the bone groove 601 Form a stable support; the rear elastic support 506 is arranged at the rear end of the fixed housing 402 and its rear end is pushed against the bone wall 201 opposite the round window membrane 109, thereby preventing the rear end of the front elastic support 505 from getting loose during...

Embodiment 2

[0055] see Figure 7 and Figure 8, the support rear seat 404 includes a cantilever bracket 502 , a support column 503 , a guide rod II 803 and a load indicator 805 . The cantilever bracket 502 is a circular sheet with several cantilevers cut inside it, and the support column 503 is located in the middle of it. The guide rod II 803 is located on the upper side of the cantilever bracket 502 and has a ratchet on its upper surface; in addition, a rack groove 804 is opened in the middle of the guide rod II 803 to cooperate with the adjustment gear 802 . The load indicator 805 is a thin piece parallel to the cantilever support 502 and is arranged at the rear end of the cantilever support 502 to monitor the initial pressure between the actuator 107 and the round window membrane 109 .

[0056] see Figure 7 and Figure 8 , the positioning device 403 includes a limiting top cover II 806 , an adjusting knob 801 and an adjusting gear 802 . The limit top cover II 806 is arranged on ...

Abstract

The invention discloses a fixed support for a round window excitation type artificial middle ear actuator, which includes a fixed shell, an elastic support, a positioning device and a supporting back seat; there are several elastic supports, which are arranged symmetrically on both sides of the fixed shell. It is used to adjust the posture of the actuator, so that the actuator and the round window film are kept on the same axis; the positioning device is located on the top of the rear end of the fixed shell, and is used to adjust the position of the supporting rear seat, so that the supporting rear seat can be in a One-way step-by-step propulsion; the supporting rear seat is placed at the rear end of the fixed shell to provide support for the actuator, so that the initial pressure is maintained between the actuator and the round window membrane; when working, the actuator is installed in the fixed shell . Provide more stable and reliable support and fixation for the actuator through the mechanical structure; at the same time, the actuator fixing bracket can also monitor the initial pressure between the actuator and the round window membrane, and can be easily operated clinically A more precise control of the initial pressure is achieved, and the problem of uncontrollable coupling between the actuator and the round window membrane is avoided.

Description

technical field [0001] The invention relates to an auxiliary fixing device for ear surgery. More specifically, the present invention relates to a fixing bracket for a round window vibration-exciting artificial middle ear actuator. 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, sensorineural hearing impairment and mixed 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 pat...
