Ear Implants TRIZ Cases

Break-off shaft segments let surgeons match middle ear anatomy during implantation, improving fit, stability, and sound conduction.

A break-off connecting element lets surgeons adjust ossicular prosthesis configuration during surgery for better fit, sound transmission, and lower displacement risk.

Angled spring elements reconstruct the middle ear conductive chain while preserving sound transmission and mobility despite tissue scarring.

A spring washer preloads the ball joint to eliminate play while preserving vibration transmission after surgery.

Patient imaging guides 3D SLA fabrication of biocompatible stapes prostheses to improve anatomical fit and sound conduction.

Circumferential spikes on an ossicular prosthesis engage the stapes head, preventing displacement and improving sound conduction without custom shaping.

Monolithic lever system generates consistent clamping force on auditory ossicle prosthesis shafts via elastic deformation.

A prosthesis uses breakable web elements to detach radially outer portions and adjust the securing element surface area.

A suction grasper instrument stabilizes ossicular prostheses using pneumatic force at the distal tip.

A drug-eluting stapes prosthesis integrates medication delivery with mechanical replacement in a single implant.

A tympanic membrane repair device uses an overlay member, underlay member, and securement member to anchor a graft in place.

Integrated removable actuating jaws grip the incus directly, eliminating separate fixation tools and reducing hand tremor risks.

A prosthetic joint uses an elastic receiving part to allow rotary movement between fastening elements.

A modular middle ear prosthesis uses an elongate cavity to accept interchangeable plug inserts for precise length adjustment.

An arched titanium prosthesis anchors to the hammer handle via a U-shaped fork, leveraging middle ear muscles for stable sound transmission.

Segmented web elements in a ceramic head plate twist locally to accommodate eardrum movements, reducing pressure peaks on the tissue.

Elastic prostheses with adjustable lever conditions improve hearing by adapting to individual anatomical variations.

A variable-length ossicular prosthesis uses plastically deformable partial strands to adjust axial length intraoperatively.

A backing section projects into a receiving space to bear against the stapes head.

Segmented headplate elements assemble into a single standard prosthesis, reducing inventory complexity while maintaining sound transmission stability.

Arcuate bulges on the elastic clip improve implantation ease and stability while protecting adjacent vessels from impairment.

An elastic bar deforms the clamping jaws for placement, then recovers to fixate the prosthesis without damaging the auditory ossicle.

Breakable engagement part secures prosthesis during transport, eliminating handling damage and multiple tool requirements.

A thin metal sheet base plate with integrated holding webs secures auditory ossicle prostheses within compact packaging.

A ball joint prosthesis shaft adjusts length via snapping balls into recesses.

Adjustable helical coil eliminates crimping to prevent pressure necrosis and ossicular discontinuity.

Pointed projections penetrate the stapes footplate to prevent ossicular prosthesis displacement caused by trauma or cicatrisation.
