37 results about "Middle ear function" patented technology

The primary function of the middle ear is to efficiently transfer acoustic energy from compression waves in air to fluid–membrane waves within the cochlea.

Middle Ear Fixation Structure

An implantable fixation structure includes a c-shape bone fixation clip adapted to fit over and attach to a bony bridge element in the middle ear of a patient. A c-shape electrode fixation clip is adapted to fit over and attach to an electrode array element in the middle ear of the patient. A connecting bar has a first end connected to the bone fixation clip and a second end connected to the electrode fixation clip. A coupling clip is connected to the connecting bar between the first end and the second end and adapted to fit over and attach to a cochlear implant element and hold the cochlear implant element in a desired position relative to the middle ear of the patient.

Ear vibration measurement method and device

InactiveCN106264548AAudiometeringSensorsCamera lensStapes head
An embodiment of the invention discloses an ear vibration measurement method and device. An SLD (superluminescent diode) emits near infrared light, the near infrared light is transmitted to a sample arm and a reference arm through an OC (optical circulator); light of the reference arm is focused on a reference mirror through a pair of lenses, light of the sample arm is input into a handheld probe through an optical fiber and is scanned to a tympanic membrane and a stapes head below the tympanic membrane through a scan lens and a relay lens in the probe; light returning from the sample arm and the reference arm is transmitted to the OC through an optical fiber coupler; projection is performed to a line-scan digital camera through a lens and grating scattering. By means of a low-coherence characteristic of a broadband light source and tissue penetrability of the near infrared light, the high-resolution tomography technology for internal microstructure of biological tissue is developed to vibration measurement, and the current situation that the department of otology can only perform indirect detection on middle ear functions clinically is changed.
