Bone Implant TRIZ Cases
- Patient-Specific Bone Graft Shaping for Glenoid Implant Seating
A bone press reshapes graft blanks to match worn glenoid surfaces, improving implant seating while preserving bone and reducing loosening risk.
- Convertible Humeral Anchor for Shoulder Prosthesis Conversion
A modular humeral anchor enables anatomic-to-reverse shoulder conversion without stem removal, helping preserve bone and biomechanics.
- Expandable Lordotic Intervertebral Cage Ratchet for Narrow Insertion
An integrated ratchet lets an intervertebral cage enter in a compact form, then expand and adjust lordosis to restore disc height and spine alignment.
- Tibial Baseplate Pockets and Keel for Stronger Cement Fixation
Recessed pockets, channels, and a textured keel improve bone cement interlock, reduce tibial baseplate micro-motion, and simplify fixation choice.
- Intervertebral Spacer Anchors for Single-Incision Spinal Fusion Stability
Simultaneous upper and lower anchor deployment stabilizes an intervertebral spacer, reducing motion and avoiding separate pedicle screw incisions.
- Expandable Spinal Fusion Implant for In-Situ Disc Spacing
A ramp-expanded spinal fusion implant is inserted through an endoscopic tube, then expanded in situ to maintain disc spacing and restore stability.
- Porous Ceramic Scaffold With Uniform Dual-Scale Open Pores
Cellulose-assisted foaming creates uniformly distributed large and micro open pores in porous ceramics for bone scaffolds and nutrient transport.
- Patient-Specific Implant Data Storage for Surgical Plan Access
Embedded implant data links patient anatomy, implant characteristics, and surgical steps to improve fit, alignment, and post-implant access.
- Hydraulic Taper Separation for Modular Orthopaedic Implant Disassembly
Pressurized fluid released through a transverse passage separates orthopaedic taper joints with less manual effort during revision or intraoperative disassembly.
- Bone Staple Structure for Compression and Stable Fixation
A movable bone staple with angled side sections and a resilient middle section improves compression, force distribution, and fixation stability.
- Segmented Bone Screw Structure for Precise Spinal Fusion Fixation
Oblique screw passages and segmented helical features improve alignment precision and fixation strength in spinal bone fusion.
- Expandable Spinal Cage Structure for Minimal-Access Lordotic Fusion
A three-piece cage expands laterally and vertically after insertion, enabling minimal-access spinal fusion with lordotic alignment and stronger support.
- Trephine Bone Graft Harvester With Integrated Morselized Bone Collection
A nested trephine cutter and distal scoop morselize, move, and retain bone at one site to avoid donor site pain and improve graft harvest efficiency.
- Demineralized Cortical Bone Gel for Moldable Shape Retention
Demineralized cortical bone particles are autoclaved into a cohesive gel that stays moldable while holding shape in bone void repair.
- Parallel Jaw Inserter for Expandable Cervical Interbody Implants
A parallel jaw inserter expands and locks a hinged cervical interbody implant, enabling adjustable lordosis with a smaller insertion footprint.
- Expandable Lordosis Spacer for Disc Height and Spinal Alignment
Inserted at minimal distraction height, this expandable spacer restores disc spacing and lordosis while reducing bone removal and installation force.
- Flexible Electrode Array for Intraoperative Prosthesis Biofilm Disinfection
Low-intensity currents through a shape-adaptive electrode array weaken implant biofilms in minutes and improve antibiotic action during surgery.
- MgO Osteostimulative Implant Surface for Bone Integration
A cured MgO-based implant surface adheres to bone, avoids thermal damage, and improves osseointegration and implant stability.
- Modular Spacer Mold Inserts for Precise Fit and Easy Extraction
Interchangeable inserts and detachable rigid half-shells form anatomically matched PMMA joint spacers in one step while easing extraction.
