Objectives

The primary objective is to procure two portable diathermy electro-surgical units for clinical use at Ngwelezane Hospital. The procurement seeks to acquire reliable, high-performance medical equipment that meets rigorous safety and clinical standards, ensuring immediate operational readiness and sustained functionality through comprehensive warranties, training, and long-term maintenance support.

Scope

The scope covers the complete supply chain for two units, including delivery, installation, testing, calibration, commissioning, and initial training at the hospital. The supplier must provide all essential accessories, a starter pack for immediate operation, dual physical and digital copies of user and service manuals, and calibration software. Following a minimum twenty-four-month warranty period, the successful bidder must submit a fully costed, comprehensive maintenance and service agreement for three years, with a renewable option. The contract is a one-off supply evaluated under an 80/20 preference point system, with twenty points reserved for South African-owned enterprises. All prices must be firm, inclusive of VAT, and valid for ninety days.

Technical Requirements

• Performance & Operating Modes: High-power electrosurgical unit operating between 200 kHz and 3.5 MHz. Must support monopolar and bipolar modes with precise variable outputs: Pure Cut (0–300W), Blend (6–200W), Pin Point Coagulation (0–120W), Spray Coagulation (0–80W), and Bipolar Cut/Coagulation (0–70W).
• Safety & Alarm Systems: Integrated audible and visual alerts for activation and patient return electrode faults. The system must be fail-safe, instantly cutting power to zero upon electrode disconnection or inadequate contact. Simultaneous hand and foot switch activation must be electronically prevented.
• Controls & Interface: Touch-pad power regulation paired with a high-visibility digital display. The foot pedal requires mechanical anti-depression protection, fluid sealing, and detachable, reusable connectors.
• Electrical & Regulatory Compliance: Operates on 220V±10%, 50Hz single-phase AC with fused live and neutral circuits. Must comply with IEC 60601-1, IEC 60601-2-2, CE certification, SANS 0142 wiring codes, and Occupational Health and Safety Act regulations. Full electromagnetic interference protection is mandatory.
• Documentation & Training: Provision of two bound sets plus digital copies of user and original service/repair manuals, including schematics, PCB layouts, and fault-finding guides. Calibration and maintenance software must be supplied at no additional cost. Technicians must receive manufacturer-equivalent, PCB-level training with a formal certificate of competency.
• Warranty & Logistics: Minimum twenty-four-month warranty covering all maintenance, travel, and downtime extensions. A loan unit must be provided if the main unit is removed for repairs. Spare parts must remain available for ten years, with documented local stock levels and defined delivery timelines.

Skills Requirements

• Local Service Infrastructure: Establishment of a dedicated service and repair facility within KwaZulu-Natal, staffed by permanently employed or subcontracted technicians who hold original equipment manufacturer (OEM) certifications.
• Advanced Technical Expertise: Proficiency in calibrating, maintaining, and diagnosing electrosurgical equipment down to the individual circuit board component level. Ability to conduct formal acceptance tests and deliver structured, certified training programs for hospital engineering staff.
• Regulatory & Compliance Proficiency: Demonstrated knowledge of South African health product regulations, including possession of a valid SAHPRA license for medical device distribution. Familiarity with preferential procurement frameworks, Central Supplier Database (CSD) verification protocols, and tax compliance documentation.

Key Terms & Clarifications

Diathermy/Electrosurgical Unit: A medical device utilizing high-frequency electrical currents to precisely cut biological tissue or coagulate blood during surgical procedures.

Monopolar vs. Bipolar: Monopolar configuration uses a single active electrode and a distant patient return pad, while bipolar passes current between two tips on the same instrument, minimizing stray energy and reducing burn risks.

PCB-Level Training: Advanced technical instruction enabling engineers to troubleshoot, repair, and replace components at the printed circuit board level, rather than relying solely on module replacement.

SAHPRA License: Mandatory authorization from the South African Health Products Regulatory Authority, legally permitting a company to manufacture, wholesale, or distribute medical devices within South Africa.

IEC 60601-2-2: An international safety standard specifically governing the electrical safety, performance, and EMC requirements of high-frequency surgical equipment.
