Objectives

To procure, install, and commission a single surgical bone miller system at Dr Pixley Ka Isaka Seme Memorial Hospital. The primary objective is to enable intra-operative generation of autologous bone grafts for orthopaedic, spinal, and trauma procedures, ensuring clinical reliability, regulatory compliance, and long-term operational sustainability.

Scope

The contract encompasses the complete supply, delivery, installation, validation, training, and lifecycle support for one bone miller unit. Scope includes provision of the main machine, cutting assemblies, optional suction/dust management interfaces, sterilization-compatible accessories, and a starter pack for immediate deployment. The supplier must deliver comprehensive user and service documentation, conduct acceptance testing alongside hospital management, and guarantee spare parts availability, technical support, and software/firmware upgrades for a minimum of ten years post-installation.

Technical Requirements

• Performance & Capacity: Throughput of 0.05–1.0 kg/hour with vendor-stated yield per minute. Accepts bone fragments/cores up to 25 mm length and 8–15 mm thickness. Output particle sizes must be adjustable via cartridges, covering 0.5–3.0 mm and coarse 3–8 mm ranges, with distribution data provided.
• Safety & Thermal Management: Engineered to minimize thermal necrosis, maintaining strict temperature control at the cutting interface to preserve bone cell viability.
• Regulatory & Electrical Compliance: Must be newly manufactured (no refurbished units). Complies with IEC 60601-1 and 60601-1-2 medical electrical standards, CE certification, SANS wiring codes, and Occupational Health and Safety Act requirements. Features EMI protection, hospital-grade power cabling (minimum 3 metres), and a 15A approved plug.
• Documentation & Software: Includes complete English-language user and service manuals (bound or digital formats), circuit schematics, PCB layouts, fault-finding guides, and calibration/maintenance software. All software keys, passwords, and troubleshooting tools must be provided at no extra cost.
• Spares & Lifecycle Support: Firm written commitment to supply spares, components, and upgrades for ten years. Supplier must declare local KwaZulu-Natal spare inventory, specify spare parts delivery lead times, and provide loan units during repairs. Patient-safety-related upgrades must be supplied free of charge.
• Testing & Validation: Subject to potential clinical evaluation by department experts. Final acceptance testing must be conducted jointly with Health Technology Services and hospital management prior to payment release.

Skills Requirements

• Technicians must hold official training/certification from the original equipment manufacturer (OEM) to perform servicing, repairs, and calibration.
• Dedicated support personnel must guarantee response within 24 hours of equipment malfunction, with clear technician-to-equipment ratios disclosed.
• Capability to deliver structured operational and maintenance training to clinical staff and biomedical engineering teams.
• Proficiency in navigating South African medical device regulatory frameworks (SAHPRA, CE, IEC, SANS) and maintaining compliant documentation.
• Ability to coordinate site-specific installation, commissioning, and acceptance testing while adhering to hospital safety, infection-control, and electrical compliance protocols.

Explanation of Unusual Terms

• Autologous Bone Graft / Morselized Auto Graft: Patient-derived bone material milled intra-operatively for immediate implantation. Eliminates rejection risks and avoids reliance on donor bone sources.
• SAHPRA Registration: Mandatory licensing by the South African Health Products Regulatory Authority, confirming the medical device meets national safety, efficacy, and quality standards for clinical distribution and use.
• Thermal Necrosis Control: Critical engineering requirement ensuring the milling process does not overheat bone tissue, which would destroy living cells and compromise graft integration success.
• IEC 60601 Series: International standards governing the safety and essential performance of medical electrical equipment, ensuring protection against electrical hazards, mechanical risks, and electromagnetic interference.
