1. General Description
The Crossbar interface acetabular grater head is a precision-engineered surgical instrument designed for acetabular preparation during total hip arthroplasty and revision procedures. It is compatible with advanced Crossbar connection systems, ensuring seamless integration with major global brands such as Stryker, Synthes, and Zimmer. In addition to Crossbar, Hexagonal and Bridgeback interfaces can also be produced to meet specific surgical and system requirements. The reamer handle typically uses the Hudson interface, but other connection types compatible with international brands like Stryker, Synthes, and Zimmer can also be produced. Manufactured from medical-grade stainless steel (420B), it offers exceptional durability, biocompatibility, and a hardness of approximately 45 HRC. Sizes are available in 1mm increments, allowing for precise customization in both minimally invasive and traditional surgeries.
2. Features
- Material: Constructed from medical-grade stainless steel (420B) for superior strength, wear resistance, and biocompatibility.
- Interface Options: Available with Crossbar, Hexagonal, and Bridgeback interfaces to suit a wide range of surgical systems.
- Handle Compatibility: Standard reamer handle connection uses the Hudson interface, with options for Stryker, Synthes, Zimmer, and other international systems.
- Precision Engineering: Sizes range from 36mm to 66mm, available in 1mm increments, ensuring accurate acetabular cavity preparation for implant placement.
- Polished Perforated Design: Lightweight design improves surgical visibility, reduces friction, and enhances material removal efficiency.
- Sterility: Delivered non-sterile; sterilization is required prior to use.
3. Intended Use
The Crossbar acetabular grater head is designed for orthopedic surgeries, specifically for the preparation of the acetabulum during total hip replacements and revision surgeries. Its precise design ensures optimal shaping of the acetabular cavity to fit the prosthetic cup.
4. Indications
- Primary Total Hip Arthroplasty: For patients with severe hip joint degeneration caused by osteoarthritis or rheumatoid arthritis.
- Traumatic Hip Injuries: Including acetabular fractures requiring total hip reconstruction.
- Hip Revision Surgeries: Where reshaping or replacement of the acetabulum is necessary.
- Developmental Dysplasia of the Hip (DDH): Corrective acetabular preparation for joint reconstruction.
5. Contraindications
- Active Infection: Localized or systemic infections at or near the surgical site.
- Severe Bone Loss: Patients with inadequate bone quality or quantity to support prosthetic implants.
- Material Sensitivity: Allergic reactions to stainless steel 420B or its components.
- Non-Surgical Alternatives: Situations where non-invasive treatment options suffice for the patient’s condition.
