5 results about "Round window" patented technology

Systems and methods can be employed to access the middle ear through the tympanic membrane for the delivery of therapeutic agents to, for example, the round window niche adjacent to the cochlea under direct visualization. The systems and methods can also be used to improve accessibility and visualization for various otologic procedures, such as, but not limited to, cholesteatoma removal, tympanic membrane repair, and ossicular chain repair.

The present application relates to the technical field of otological microsurgery instruments, and discloses a cross-shaped round window membrane incision knife with depth control for otological minimally invasive surgery, which comprises a knife rod, a cross-shaped knife head is arranged at the operating end of the knife rod, a detachable depth control mechanism is arranged on the outside of the knife rod behind the cross-shaped knife head, a grip type handle assembly is arranged at the end of the knife rod away from the cross-shaped knife head, and the grip type handle assembly comprises a grip type handle, and a thimble is arranged at the end of the grip type handle close to the knife rod. In the present application, the cross-shaped symmetrical blade edge realizes multi-point stable support, effectively avoids the slippage of the knife head on the surface of the wet round window membrane, and the incision position is accurate; the sharp symmetrical cutting forms a regular cross-shaped incision, there is no disorganized tearing, the incision edge is neat, and this is beneficial to postoperative healing and electrode implantation sealing; the annular flange type depth control mark block forms physical limiting, the cutting depth is locked in a safe range, and overcutting damage to the inner ear is avoided in structure.

The present application relates to the technical field of biological medicine, and more particularly to a liposome dispersion liquid and ear drops for penetrating the tympanic membrane and the inner ear round window membrane. The present application designs a liposome dispersion liquid which can effectively penetrate the complete path of the tympanic membrane and the inner ear round window membrane after non-invasive ear drops through the external auditory canal, so as to avoid the tympanic membrane perforation caused by intratympanic injection and reduce the pain and discomfort of patients. The liposome dispersion liquid of the present application has good stability, the prepared ear drops can realize efficient delivery of targeted inner ear drugs, has the characteristics of non-invasive and convenience, and has a wide application prospect in the medical field.
