Finger Joints TRIZ Cases
- Vacuum Gripper for Small Joint Prosthesis Cups
Triangular proximal parts and vacuum seals enable precise impaction of small joint prostheses, preventing bone damage from imprecise placement.
- Hydraulic Implant Introducer for Controlled Hydrogel Delivery
A hydraulic implant delivery system uses saline pressure to push hydrogel implants through a nozzle lumen into joint repair sites.
- Carpometacarpal Prosthesis with Tapered Stem and Porous Surface
A tapered component stem with a porous surface achieves friction-tight fixation within the metacarpal bone.
- Modular Bone Joint Implant with Dual Articulation Points
Segmenting the mechanism into two independent points accommodates shifting rotation axes, preventing subsidence and loosening in carpometacarpal joints.
- Curved Bone Plate for Ulna Stabilization
An arcuate bone plate distributes load across the distal radius to reduce stress concentration and tendon disruption.
