BackThe NAVISURG StemDraw™ Hip Extractor is specifically designed to safely, accurately, and minimally invasively remove femoral stems during hip revision surgery. The device clamps directly onto the stem’s taper, enabling effective traction while minimizing bone and soft-tissue damage. Its integrated slap hammer system enhances force control, shortens operative time, and increases procedural efficiency for the surgeon.
1. Product Information
- Product name: NAVISURG StemDraw™ Hip Extractor
- Device Owner / Brand Owner: NOVAMED GLOBAL JOINT STOCK COMPANY
- Country of Origin: Vietnam
- Indications: Designed to assist in the removal of femoral stems in revision total hip arthroplasty, helping to minimize damage to surrounding bone and soft tissue.
2. Product Description
- The Novamed StemRelease™ System is designed to directly engage the taper of the femoral stem after removal of the femoral head.
3. Indications for Use
Used in the following cases:
- Revision surgery for removal of femoral stems in total hip arthroplasty.
- Stem loosening.
- Periprosthetic joint infection.
- Change of implant design or material during revision surgery.
- Fractured, worn, or failed femoral stems requiring replacement.
4. Contraindications
Not intended for use in the following cases:
- Fractured or severely deformed femoral stems with no accessible taper for engagement.
- The femoral bone too weak or unstable to withstand extraction forces.
- Limited surgical exposure with insufficient working space.
- Patients contraindicated for revision surgery.
5. Intended Users
- Orthopedic trauma and joint replacement surgeons.
- Operating room staff trained in orthopedic instruments.
- Surgical technicians assisting in revision arthroplasty procedures.
6. Product Advantages
Key advantages:
- Reduced bone damage: Provides linear extraction force, reducing the risk of femoral canal bone loss.
- Shorter operative time: Standardized extraction process, significantly faster than manual techniques.
- Optimized control: Supplied with a slide hammer allowing active traction or assisted extraction using surgical mallets.
- High durability: Manufactured from corrosion-resistant medical-grade steel, capable of withstanding high forces in complex revision cases.
7. Instructions for Use:
- Remove the femoral head component.
- Clean the taper of the femoral stem.
- Attach the instrument to the taper and securely tighten the clamping mechanism.
- Connect the slide hammer or traction mechanism.
- Apply axial traction to extract the stem from the femoral canal.
- Remove the instrument and proceed with the revision procedure.
8. Storage & Sterilization
- Steam sterilization according to regulations.
- Thorough cleaning after each use, particularly threads and clamping components.
- Store in a dry environment and avoid strong impacts.
- Do not use if deformation, cracks, loose threads, or malfunctioning clamps are observed.
9. Warnings
- For use only by surgeons trained in revision total hip arthroplasty.
- Avoid off-axis traction to reduce the risk of femoral fracture.
- Maintain a sterile environment throughout the procedure.
