Finger Joints TRIZ Cases
- Orthopedic Connection Assembly With Curved Groove Self-Alignment
A curved groove and truncated cone create self-aligning linear contact in orthopedic joints, avoiding insertion damage in tight spaces.
- Curved Taper Connection for Self-Aligning Orthopedic Components
A convex curved taper shifts point contact into a plastically deformed strip fit, securing orthopedic components without longitudinal expansion.
- Interphalangeal Implant Retainer for Contact-Free Precise Insertion
A jig retainer with driving rod insertion enables contact-free implant handling, precise placement, and simpler interphalangeal surgery.
- Crosslinked Polyisobutylene Polyurethanes for Durable Implants
Crosslinked polyisobutylene polyurethane resists oxidation and hydrolysis, improving implant toughness and long-term stability.
- Joint Implant Interface Registration for Rolling Motion Durability
Complementary curved interface features keep joint implant elements aligned in rolling motion, reducing wear while preserving hinge-like movement.
- Dermal Cap Geometry for Metatarsal and Metacarpal Joint Resurfacing
A shaped, freeze-dried dermal cap restores damaged metatarsal or metacarpal cartilage surfaces to relieve pain and improve joint function.
- Finger Joint Spacer Mold Cavities for Pressure-Free Bone Cement Filling
Split mold cavities with venting and fastening enable reproducible PMMA finger joint spacers in varied sizes without pressure filling.
- Lubricious MTP Joint Implant Geometry for Native Cartilage Articulation
A lubricious, layered MTP joint implant uses anatomy-matched curvature to lower cartilage stress, preserve bone, and ease revision surgery.
