Embodiment 1

[0035] Combined with the manual figure 2--4. The round window vibration-exciting actuator with adjustable posture and posture includes a telescopic device 30, a fixed support device 20, and an angle and distance adjustment device 52. The telescopic device 30 is connected to the external energy supply device through wires, so The fixed support device 20 is fixed to the surrounding bone of the patient's round window through the bone nail 17, which provides a fixed support for the present invention. The telescopic device 30 is connected with the angle and distance adjustment device 52 through a thread pair. The actuating end of the telescopic device 30 is in contact with the round window membrane of the patient, and the telescopic device 30 is rotated by a torque measuring screwdriver to adjust the preload between the actuating end of the telescopic device 30 and the patient's round window membrane; the angle and distance adjustment device 52 is in contact with the fixed support...

Embodiment 2

[0043] Combined with the manual Figure 5 --6, the telescopic device selects a piezoelectric stack, and the telescopic device selects a telescopic device 60 with a displacement amplifying device, and the piezoelectric stack is placed in a displacement amplifying device 65, and the displacement amplifying device 65 One end is fixedly connected with the closed end of the housing, and the other end is fixedly connected with the connecting end of the transmission rod.

[0044] The displacement amplifying device has a rhombus-shaped symmetrical structure, and the diagonals are perpendicular to each other and are not equal. The piezoelectric stack is placed on the long diagonal of the rhombus-shaped displacement amplifying device. When the drive voltage is input to the telescopic device, the piezoelectric stack will deform under the inverse piezoelectric effect and perform telescopic motion. After being amplified by the displacement amplification device, the motion will be transmitt...

Embodiment 3

[0047] Electromagnetic actuators are used for the retractor.

[0048] Other technical solutions are the same as in Embodiment 1.

[0049] The structure of the torque-measuring screwdriver 40 used in the present invention is: the torque-measuring screwdriver 40 includes main rod 41, strain gauge 42, screwdriver head 43 and display screen 44, when the torque-measuring screwdriver 40 preloads the telescopic device, the strain gauge 42 will transmit the signal to the processing unit inside the screwdriver head 43 and display it on the display screen 44 to determine the size of the pretightening force.

Abstract

The invention provides an attitude-adjustable round window excitation type actuator comprising a telescopic device, a fixed supporting device and an angle and distance adjusting device. The telescopic device is connected with an external energy supply device through a lead. The fixed supporting device and the round window peripheral bone substance of a patient are fixed through a bone nail. The telescopic device is connected with the angle and distance adjusting device through a thread pair. The actuating end of the telescopic device is contacted with the round window membrane of the patient. The telescopic device is rotated through a torque measuring screwdriver to adjust the pre-tightening force between the actuating end of the telescopic device and the round window membrane of the patient. The angle and distance adjusting device and the fixed supporting device are contacted by a spherical pair and connected by a special screw, and the actuating angle of the telescopic device and the round window membrane of the patient is adjusted by adjusting the special screw. The telescopic device directly excites the round window membrane, and the attitude of the telescopic device can be adjusted through the angle and distance adjusting device according to the position of the round window membrane.

Description

technical field [0001] The invention relates to a round window vibration-exciting actuator with adjustable posture and posture, belonging to the technical field of hearing aids. Background technique [0002] Hearing impairment is one of the most common diseases in society. According to the different mechanism of injury, hearing impairment can be divided into conductive hearing impairment and sensorineural hearing impairment. With the continuous development of science, conductive hearing loss can generally be treated by surgery, but there is no good treatment method for sensorineural hearing loss under the existing science and technology, and hearing aids are mostly used to improve hearing. However, traditional hearing aids can only solve mild to moderate sensorineural hearing impairment; it is inconvenient to wear; the output sound signal and the sound signal fed back by the ear canal are prone to aliasing, which reduces the clarity of the sound signal that the patient final...
