Product Details
Harmony Acetabular System: China Factory Suppliers for Advanced HA+Ti Coating and Press-Fit Stability
Surface Screw Hole Design
- DDH: 6 screw holes optimized for deformity fixation.
- Standard: 3 screw holes fixed to the posterior superior bone for effective anchoring.
Minimized Backside Wear
- Utilizes a triple locking system combining taper connection, concave tooth matching, and an annular anti-retrogression mechanism.
- High dome support ensures maximum contact between the polyethylene liner and outer cup for effective force transmission, reduced micro-motion, and minimized debris.
- An ultra-mirror polished inner surface further decreases liner wear.
Ti+HA Double Coating
- Increases cup surface roughness to enhance friction and provide immediate stability.
- Good biocompatibility, effectively inducing bone growth.
180° and Deepened Curvature Design
- 180° full coating coverage to increase the surface area for bone growth.
- 2mm extended cup can reduce soft tissue damage during liner implantation.
- Deepened curvature design to ensure sufficient bone coverage.
Frequently Asked Questions
What options are available for the screw hole design?
The system offers two options: a DDH configuration with 6 screw holes for deformity fixation, and a Standard configuration with 3 screw holes designed to fix to the posterior superior bone for effective anchoring.
How does the system minimize backside wear?
It utilizes a triple locking system (taper connection, concave tooth matching, and an annular anti-retrogression mechanism), high dome support for maximum contact, and an ultra-mirror polished inner surface to minimize liner wear and debris.
What are the specifications of the Ti+HA double coating?
The double coating features a porosity of 70%, with a Titanium (Ti) coating thickness of 325 µm and a Hydroxyapatite (HA) coating thickness of 50 µm.
What are the benefits of the Ti+HA double coating?
The Ti+HA coating increases the cup's surface roughness to enhance friction and deliver immediate stability, while offering excellent biocompatibility to effectively induce bone growth.
How does the 180° and deepened curvature design improve clinical outcomes?
The 180° full coating increases the surface area for bone growth, the deepened curvature ensures sufficient bone coverage, and the 2mm extended cup helps reduce soft tissue damage during liner implantation.
