Low Profile Mis Acetabular Grater Reamer Heads (Minimally Invasive Surgery)

1. General Description

The MIS Acetabular Grater Head is a specially designed surgical tool for minimally invasive hip surgeries (MIS), offering enhanced accessibility and efficiency compared to standard acetabular reamers. Its unique design, which features two missing quadrants, provides reduced bulk and improved maneuverability in smaller surgical incisions, making it ideal for MIS procedures. Manufactured from medical-grade stainless steel (420B), it combines high strength, biocompatibility, and durability, with a surface hardness of approximately 45 HRC. Compatible with Crossbar, Hexagonal, and Bridgeback interfaces, this grater head integrates seamlessly with major global surgical systems, including Stryker, Synthes, and Zimmer.

2. Features

• Optimized for MIS: The two missing quadrants reduce bulk, enhancing maneuverability in minimally invasive procedures.
• Material: Constructed from 420B stainless steel, offering superior durability, corrosion resistance, and biocompatibility.
• Interface Options: Available in Crossbar, Hexagonal, and Bridgeback designs, ensuring compatibility with leading global brands.
• Handle Interface: Standard connection is the Hudson interface, with additional options for Stryker, Synthes, and Zimmer handles.
• Precision Sizing: Available in 1mm increments (36mm to 66mm) for accurate acetabular preparation and implant fitting.
• Polished Perforated Design: Reduces weight, improves debris removal, and ensures smooth performance during reaming.
• Sterility: Delivered non-sterile, requiring sterilization before use.

3. Intended Use

The MIS acetabular grater head is designed for orthopedic surgeries, particularly for minimally invasive approaches to primary and revision total hip arthroplasty, where precise acetabular preparation is required.

4. Indications

1. Primary Total Hip Arthroplasty: For patients with advanced hip joint degeneration caused by osteoarthritis or rheumatoid arthritis.
2. Hip Fractures and Trauma: Cases requiring acetabular preparation and reconstruction.
3. Revision Hip Surgeries: To reshape or replace the acetabular cavity during implant revisions.
4. Developmental Dysplasia of the Hip (DDH): Corrective acetabular preparation for joint reconstruction.

5. Contraindications

1. Active Infection: Localized or systemic infections at or near the surgical site.
2. Severe Bone Loss: Patients with inadequate bone quality or structure for implant support.
3. Material Sensitivity: Allergic reactions to stainless steel 420B or its components.
4. Non-Surgical Alternatives: When non-invasive treatment options are more suitable for the patient's condition.
